Notes to the reader
Because this publication is distributed in an international sales network, the devices in the pictures (both
standard and accessories) may vary from country to country. Some important protective covers, which are
required by law in some countries, have in some of the pictures been removed in order to ensure better
visibility to the part in question. The machine must not be used without the protective covers. To ensure user
safety, please check that all protective covers are undamaged and installed before starting work.
In this manual, the "left side" and the "right side" of the machine are always viewed from behind the machine
towards the driving direction.
Tume-Agri Oy continuously develops its products and reserves the right to make changes and improvements
to the products described in this manual without committing to change previously sold products.
2. GENERAL SAFETY INSTRUCTIONS
Read these instructions carefully before using, servicing or handling the TUME Seeder Fertilizer.
It is strictly prohibited to work or stay under a machine that is supported by the hydraulic system
only! Always close the safety valves of the lift cylinders to prevent the machine from collapsing.
Always lower the machine if you have to leave it unattended.
The support leg of the drawbar, which is available as accessory, is designed to facilitate fitting the
seeder to the fixed tractor pull point, or when used on top, to facilitate fitting the device to a rear
harrow. Use the support leg only when the hoppers of the machine are completely empty and it is
standing on a level surface. When dismounting the machine, always lower it down on the coulters and
ensure that it cannot move. Do not park the machine on sloping ground.
It is strictly prohibited to ride or sit on the footstep or the machine when it is moving! The driver must
ensure that there are no people near a moving machine.
Do not grease, adjust, or clean the machine when it is moving. When servicing the machine, turn off
the engine and put the hand break on.
All protective covers must be in place.
Make sure that the drawbar, hydraulic hoses and electric wires are correctly connected to the tractor
and the machine.
Damaged hydraulic hoses and connections must immediately be replaced. Ensure that the hydraulic
valves and connections on the tractor are undamaged and do not leak. The machine rests on them
during transportation.
Due to the structure of the machine's hydraulic system, it cannot be used unless the 12V power
supply is switched on.
If the power supply is damaged, utmost care must be taken when using the hydraulic system, because
the movements will be unlimited!

2
Hydraulic row markers, which are available as accessories, can move very fast, particularly if the
throttle valve is completely open, and the hydraulic input is high. Particular care should be taken
when raising and lowering the markers for the first time to test their operation. Ensure that nobody is
in the way or under a marker that is only supported by the hydraulic system!
Ensure that at least 20% of the tractor weight rests on the front axle of the tractor under all
circumstances. If necessary, use extra weights. Be particularly careful if the seeder fertilizer is
connected to a rear harrow, and you are lifting it with a tractor lifting device e.g. when backing.
The maximum speed in good conditions is 30 km/h. Take particular care and lower the speed when
driving over rough, uneven ground. It is preferable to move the machine only when the hoppers are
empty. It is forbidden to carry loads on top of the machine. Avoid driving over big stones or other
obstructions to keep tires undamaged.
Never choose a driving line, where the outermost wheels cannot touch the ground. This may cause
excessive tilting of the machine. Selecting the wrong driving line may lead to the machine turning
over.
Pay particular care when moving on top of the machine in for cleaning, or servicing purposes or for
filling the hopper.
The painted surface finish may emit hazardous gases when heated. Ensure sufficient ventilation
during e.g. possible welding.
Use only accessories and optional equipment that have been approved by the manufacturer. The
manufacture is not responsible for any alterations that are not made in accordance with the
manufacturer's instructions.
It is recommendable to use masks especially when using a seed-dressing device (available as
accessory). The seeder fertilizer does not essentially increase the noise level in the tractor cabin. The
possible need of hearing protection depends on the noise level of the tractor. Safety boots are
recommended when handling heavy and sharp components (such as parts of the drawbar and the set
of coulters).
If you need to transport your machine on public roads, keep the required road transport equipment
also up-to-date. Regulations may often be amended.
3. USE OF THE MACHINE
General
The Tume Nova Combi –seeder fertilizer is designed for simultaneous seeding and fertilizing particularly
in direct seeding conditions. Nova Combi is, however, also perfectly suitable for seeding minimally or
normally tilled soil.
The machine can also be used for only for seeding or only for fertilizing according to the conditions below.
Due to the structure of Nova Combi, its supporting wheels also compact the soil. In most cases the
supporting wheels close the furrows cut by the coulters.
Accessories increase the versatility of Nova Combi, and using the machine with an accessory enables
e.g. tilling or flattening the soil, seeding grass, treating the seeds before seeding, and putting tramlines on
the field simultaneously with seeding and fertilizing in one go.
Nova Combi must not be used for other than the above-mentioned purposes. It has not been designed for
e.g. transporting materials with fast speed, or storing materials in its hoppers. The loading place should be
near the field, and a fully loaded machine should be transported with a fairly low speed, taking into
consideration the load in the hoppers and the rough or uneven ground. (see section 8, page 9). It is
strictly forbidden to transport passengers on the machine!

3
Using the machine exceptionally for seeding only
When a fertilizer is not used, shift the middle wall of the hoppers to front position in order to enlarge the
capacity of the seed hopper.
If you want to ensure, e.g. because of the risk of soil drying, that the seeds are placed in the deepest
furrows, you can sow them through the fertilizer hopper. In that case you should also perform a calibration
test by using the fertilizer feeder and a calibration test chute. Note also, that the seeds may not be able to
pass through the fertilizer sieves. In that case you must remove the sieves.
To achieve maximum seeding power, both the hoppers can simultaneously be used for seeding. Note that
the calibration test must be performed for both of the feeders, and the total of the sums from both tests
forms the result representing the seeding volume.
Note, that in the above-mentioned exceptions, the seeding tables provided with the machine do not apply.
Using the machine for fertilizing only
Tume Nova Combi can also be used only for spreading fertilizer. The fertilizer is then loaded into either the
fertilizer hopper or the seed hopper, or both. Most of the instructions given in the previous chapter apply also
for spreading fertilizer only.
Please note, when loading the entire machine with fertilizer, that it is normally heavier than seeds. Do not
load the hoppers completely full, and adhere to the maximum allowable gross weights defined in the
technical specifications.
4. GENERAL SEEDING INSTRUCTIONS
Selecting the seeding depth
Nova Combi has double disc coulters with different diameters on the right and left disc. The smaller disc
defines the seeding depth, and the larger disc cuts a slightly deeper furrow for the fertilizers.
When selecting the seeding depth, the requirements of the particular seed in question and soil humidity
conditions must be considered. The correct seeding depth for the seeds you are planting should be
checked in good time, so that the seeding can take place when the humidity in that particular depth is
suitable. The suitable depth for small seeds usually varies between 1-3 cm, and for common crops the
seeding depth is usually between 4-5 cm. Always avoid seeding too deep. On the other hand, seeding
too shallow may cause problems in covering the seeds.
It is important to make sure that the smaller disc of Nova Combi reaches down to the humid soil. If the
seeding depth is too shallow, seeds may end up in dry soil, which will prevent them from germinating.
Correct seeding time
The correct seeding time is based on observing the soil humidity and temperature, as well as the
prevailing weather and weather forecasts. The optimal seeding time depends on the soil type and the
crop you are planting, so that it is impossible to give any general guidelines.
The soil at the seeding depth should be tillable, but sufficiently damp. The soil is too wet for planting, if it
packs into hard clods.
The seeding time of crops that are sensitive to frost may have to be postponed despite favorable soil
humidity conditions according to prevailing of expected weather conditions.
If zero tillage is applied and the soil is neither tilled in autumn nor in spring, the spring planting should take
place approx. 7-10 days later than when planting in tilled soil, because of the isolating and light reflecting
properties of vegetable remains.

4
Selecting the fertilizer
Tume Nova Combi uses the same coulter for spreading both the fertilizer and seeds, although in most
conditions they are placed slightly separately from each other. Fertilizers placed near the seeds can in
some conditions slow or prevent germination. Fine seeds (such as turnip rape or oilseed rape) and
skinless seeds (such as wheat) are most susceptible to such burn damages. Burn damages are currently
under research, but as there are no results yet, it is best to use traditional granular fertilizers from well
known manufacturers, with grains containing all the nutrients provided by the fertilizer. Fast soluble
nitrogen fertilizers (such as urea) should be avoided. There are no research results from using
mechanical fertilizer compounds.
They should be portioned moderately. Avoid high levels of fertilizing, or alternatively apply a divided
method, in which part of the fertilizers are applied to new growth.
General instructions for direct seeding
Applying direct seeding and omitting all soil tillage operations can result in great savings and enable
cultivation of large areas with limited machinery and personnel. In favorable conditions and particularly
with winter-grain, the yield under zero tillage is normal. In spring seeding zero tillage may result in slightly
lesser average yield compared to traditional methods.
It is recommendable to take the change to direct seeding into consideration already in the previous year,
at the latest. The field should be properly ditched, and no packed grooves made by wheels or other such
roughness should be found on the surface. Try not to stop the combine while threshing in order to avoid
forming heaps of straw in the field. The combine should have an efficient chuff cutter so that leftovers are
spread on top of the soil in as even a layer as possible. The stubble height should be less than 20 cm.
Direct seeding is best suited for autumn seeding, because in autumn the soil normally contains plenty of
moisture, which facilitates germination. Spring seeding season is often dry, and so is early summer. The
significance of the correct seeding time, soil structure, and soil type are emphasized when direct seeding
is applied to spring seeding. It is also essential to ensure the correct seeding depth and cover the seeds
properly. It is of utmost importance to make sure that the seeds will not remain visible on top of the soil!
Tume Nova Combi can be equipped with an covering disc in order to ensure that the seeds are properly
covered.
Weed control is of essential significance when direct seeding is applied. Practice has shown that annual
Glyfosate spraying in smaller dosages prior to germination either immediately before or after seeding
keeps couch grass fairly well in control. Other weeds, such as weeds grasses can, however, thrive along
the years. These should be controlled by using available chemicals, and if necessary, by applying rotation
of crops or fallowing. Fairly light soils with ideal humidity for direct seeding suffer most from weeds.
When applying direct seeding, crops should also be observed more carefully than usually in case of
diseases and pests. Control measures should be taken without delay when control thresholds are
exceeded.
Seeding into minimally tilled soil
Tume Nova Combi is extremely suitable for seeding into minimally tilled soil. Equipment that produces an
even, suitably fine, and compact soil, and which enables a sufficiently accurate working depth adjustment
should be used for minimal tilling.
Minimal tilling that takes place immediately before seeding should be extended slightly deeper than the
seeding depth, particularly in clayey soil. This ensures that suitable humidity remains in the seeding
depth.
For spring seeding it is recommendable to apply the following minimal tillage method: tilling is carried out
in 10-12 cm depth in autumn, which mixes the vegetable waste into soil surface layer, instead of letting it
form an insulating layer over the soil surface. This method enables seeding at the normal time in spring,
which is particularly important in countries with a short growth period. Tume Nova Combi enables direct
spring seeding into soil that has been lightly tilled in autumn. Light surface tilling can be carried out in
connection with seeding by connecting a Tume Cultipack rear harrow to the machine.
Seeding into normally tilled soil
Seedbed preparation should be performed by tilling the soil deeper than the seeding depth, particularly in
clayey soil. This helps maintain better humidity conditions in the seeding depth.
Coulters should be lightly pressured particularly when tilling light soil.

5
When you connect a Tume Cultipack rear harrow to Nova Combi seeder fertilizer, you can seed directly
into ploughed soil without prior separate tilling.
5. FIELD MACHINE TIRES
When applying direct seeding to certain fields, attention should be paid to maintaining and improving the
soil structure in order to maintain proper water management. The ground should also be as even as
possible.
When driving in the field, only such sets of tires that ensure sufficiently low surface pressure should be
used. Furthermore, the axle weight should be as low as possible. Driving in the fields should be avoided
in wet conditions.
6. DEPLOYMENT
Operating principle of wheel set
The longer cylinders at the ends of the machine turn a support tube frame extending the whole machine width
and used also for attaching the outer wheel pairs. Intermediate wheels are attached by joints to the tube
frame, and they are operated by their own operating cylinders. All these cylinders are connected to the same
hydraulic circuit, and have the same pressure. This is why the wheel pairs can adapt to roughness on the
ground surface, but can still maintain a stable rolling power through the entire working width (figure 1).
The structure of the support wheel set has been designed so as to provide equal pressure under all wheel
pairs when the machine is in operating position (down). When the machine is lifted to upper position, the
unfastened wheel pairs in the middle carry a slightly heavier load. This reduces the risk of damaging the outer
wheel pairs, which are most susceptible to damages during transport.
The seeding depth of the coulters is adjusted by the front working depth support wheels. The adjustment is
made separately for each coulter slide so that one wheel adjusts two coulters. The adjustment is made with
quick-release fasteners in front of the slide (figure 2). The maximum seeding depth is adjusted by pushing the
fastener latch in the lowest groove.
Correspondingly, in order to seed near the surface, fasten the latch in the upper grooves.
A special hoisting device should be used to hoist the Tume Nova on a truck (for instance to load it in the
factory). The machine is hoisted by the central wall located inside the hoppers towards the driving direction. It
has two oblong holes where you pass the hoisting devices (you will need two) and where the hoisting chains
are attached. Ensure that the chains are of equal lengths: The Nova seeder must be kept in upright position
when hoisted. Completely open the tarpaulin cover when hoisting to avoid damaging it!
You can also load Nova Combi on e.g. a truck using a loading bridge, or alternatively use a pallet equipped
with a sufficiently low ramp, and wide enough to fully accommodate the rear wheel set of the machine. Make
sure that the intermediate wheels do not fall down in between the loading bridges. As for the outer wheel
pairs, it is enough to fit only one of them on the pallet, if the machine is transported towards the driving
direction.
When backing, please note also the rear wheel scrapers, located near ground level. Beware of obstructions!
When backing over a high threshold, for instance, you can lift the scrapers by slightly lowering the machine.
Ensure that enough space is left under the coulters so that they do not hit any obstructions.

FIGURE 1. Support wheel set FIGURE 2. Adjusting the working depth
Assembling the drawbar
The drawbar is assembled according to the figure 3 below, which also shows how the drawbar is attached to
the machine. Note that the drawbar is always attached on the upper slots on the lower lugs. Attach the
hydraulic push bar also to its upper slot.
Hydraulic hoses and electric wires should be attached carefully to ensure that they cannot be damaged under
any circumstances when driving (e.g. when jackknifing). Always pass the hoses inside the box girder of the
shaft.
FIGURE 3. Drawbar
Adjust the length of the push bar so that the machine is in a horizontal position when lowered and attached to
the tractor towing hook, wheel packer or rear harrow. Ensure that the push bar cylinder is at its shortest
position when making this adjustment. Adjustment of the drawbar is made according to the actual seeding
conditions in the field.
Attaching the machine to a tractor
Nova Combi is normally attached to the tractor towing hook. It is not recommended to attach the machine to a
rear hitch attached on the tractor lower links, because that would make the tractor front too light and reduce
steerability.
The hydraulic system of Nova Combi is connected to a hydraulic output intended for external single function
cylinders on the tractor. If the machine is equipped with markers (available as accessory), they are operated
by the same hydraulic valve as lifting and lowering the machine. In this case, however, the machine must be

7
connected to the tractor's double function hydraulic output. Please note that in many tractors you should use
special hydraulic couplings recommended by the tractor manufacturer. If necessary change these parts to
those suitable to your tractor in order to ensure proper operation or the hydraulic system. The hydraulic
cylinder on the drawbar also requires an additional double function output.
Using the seeder fertilizer requires a 12 V electric connection. Electrical diagrams for the connections are
displayed on the following page .
The maximum lifting and lowering heights are adjusted by an electric valve (figure 5), which is controlled by a
pointer adjustment element located on the face bar of the machine (figure 4). The adjustment curve has two
hand-operated knobs equipped with magnets. The maximum movement range of the machine is adjusted by
using these knobs: one of the knobs adjusts the upper position, and the other adjusts the lower position /
weighting of the coulters. See section 15, Adjusting the working depth. NOTE! If the Nova Combi is equipped
with an AgromasterCan or Agrocont electronic control unit available as an option, a different method is used
for lifting and lowering. For lifting and lowering in such a case, please refer to AgromasterCan or Agrocont
guide book!
NOTE! When moving the machine, tractor power supply must be connected. Failing to use the electric valve
may lead to serious tire or coulter damage. When the electric valve does not limit the lifting movement, the
machine can be lifted so far up that the tires hit the coulters, and get damaged. IF THE ELECTRIC SUPPLY
IS OFF, UTMOST CARE MUST BE TAKEN DURING LIFTING IN ORDER TO AVOID SUCH DAMAGE.
The coupling box in front of the machine is equipped with light indicators. The green light in the middle is
always on when the machine is turned on. When the pre-defined upper position is reached, the upper red
lamp lights. Correspondingly, when the pre-defined lower position is reached, the lower red lamp lights.
If your machine is equipped with row markers, it also has a junction box shown in the figure below. Ensure
that the power cable is correctly connected: Red indicates + , Black indicates - . If your tractor is not equipped
with machinery power supply, it is best to use the battery for power supply. IN THAT CASE, PLEASE NOTE:
An extra fuse to plus conductor near the battery!
NOTE! If the Nova Combi is equipped with an AgromasterCan or Agrocont electronic control unit
available as an option, it has none of the controllers/switches described in this manual. In such a case
refer to the control unit manuals for instructions.

FIGURE 4: Adjusting the coulter pressure FIGURE 5: Lift and lowering valves
Driving instructions
When lowering the machine, it must always be simultaneously moved forward. Otherwise the coulters can get
clogged.
Avoid unnecessary driving on seeded areas. Select a suitable driving technique so as to leave as few tire
marks on the seeded area as possible.
In its upper position, the machine rests on the hydraulic valve of the tractor. This is why it is important to
ensure that the hydraulic valve of the tractor cannot accidentally be opened or start leaking during transport.
The cylinder safety cocks must always be kept open during road transport!
The front of the machine can be lifted by the tractor hydraulic system during seeding e.g. to avoid blocking.
This is done by using the drawbar cylinder which is controlled by the cylinder's own double function valve. The
same cylinder should be used also during road transport in order to achieve a larger ground clearance. In
seeding the cylinder is, however, used only when needed.
When used on even ground, the machine should be in a horizontal position. If the machine tilts forward, the

9
push bar of the drawbar should be extended. If the machine tilts backwards, the push bar of the drawbar
should be reduced. Check the seeding depths after driving a while, and adjust if necessary. Check the marker
adjustment also by evaluating the seams.
NOTE! Lift and lower the machine only when it is moving forward. Never back the machine
when the coulters are down on the ground and power transmission is on.
Check regularly, that the coulters are not clogged. Check also all seed and fertilizer pipes and remove
possible blockages. When you start seeding, estimate the area that can be managed with one hopperfull.
After that you can determine the correct hopper filling time with an electric hectar counter (accessory).
Ensure that there is a sufficient amount of seeds and fertilizer in the hopper. Because of the bottom design,
particular attention should be paid to this especially in the beginning. Do not store seeds or fertilizer in the
hopper for many days, particularly in damp weather. Dampness may make fertilizer difficult to spread.
Suitable driving speed is more important when using Nova Combi than when using traditional seeding
machines. In general, a slightly higher speed is recommended for direct seeding, compared to traditional
seeding into pre-tilled field. The suitable speed for tilled soil is usually approx. 7-10 km/h: When seeding peas,
the maximum speed is 6-7 km/h. The maximum speed during transport with the hopper empty is 30 km/h.
7. GROUND WHEEL OF THE FEEDING DEVICE
Feeding devices are powered by the ground wheel located on the left side of the machine. The ground wheel
is attached to the hopper, and is lifted when the machine is lifted. When the machine is lifted, the ground
wheel is comes off the ground, and the feeding stops. This makes having a separate power transmission
switch unnecessary.
NOTE! Do not turn the ground wheel towards backing direction! Lift the machine always to its uppermost
position before backing the tractor.
The moment the feed is detached/connected can be adjusted by lifting or lowering the ground in relation to the
hopper. This happens by adjusting the drive cable attachment point in the hub of the wheel set tube frame.
It is also possible to retract the ground wheel during transport. Then the total transport width corresponds to
the machine nominal width of: 3 or 4 meters. Optional positions are shown in figures 6 and 7.
Figure 6: Ground wheel in working position Figure 7: Ground wheel in transport position

10
8. FILLING THE HOPPERS
Filling the hoppers
When the seeding starts, it is recommended to drive the machine on the field with hoppers empty. The
fertilizers and seeds are brought to the field e.g. with a trailer, and the hoppers are filled at the field parcel. If it
is necessary to fill the seeder fertilizer far away from the parcel, extreme care must be taken when driving with
full hoppers. The maximum transport speed of 30 km/h is only allowed when driving with empty hoppers on
good roads! The maximum speed allowed when driving with full hoppers is 15 km/h.
Observe the speed at which the hoppers empty out:
• By looking into the hopper from time to time, after stopping the machine
• By reading the hectare counter (accessory) after checking how large an area can be seeded
by one hopperfull, and after noting the hectare counter reading from the previous filling
• By using electronic monitoring devices, which are available as accessories. The machine
alerts you, when there is a certain amount of fertilizer or seeds left in the hopper.
Adjustable hopper volume
You can move the middle wall between seed and fertilizer hoppers to enable adjusting the hopper volumes.
To adjust, unscrew the locking screw on the support bar and turn the middle wall to the desired position
(figure 8). Remember to lock the support bars after the adjustment. Note, that the middle wall height can also
be adjusted.
Figure 8. Adjustment bar on the hopper middle wall.
Filling the hoppers
The machine filling height is fairly large, and the hopper volume is large. This is why it is recommended to use
big sacks for filling (NOTE! Requires sufficient hoisting apparatus), or e.g. feeder spiral technology.
Big sacks can be handled with various loaders. Do not go under a hanging load. Do not lower a big sack on
top of the seeder fertilizer frame. Do not overfill the seeder fertilizer. Find out the best methods for partial
emptying of a big sack.

11
9. EMPTYING THE HOPPERS
7. EMTYING THE HOPPERS
Emptying the fertilizer hopper
The fertilizer hopper is usually emptied through the coulters. Adjust the feeder to maximum feed, spread e.g. a
tarpaulin under the machine and turn the bottom valve lever of the fertilizer feeder to its lowest position. The
hopper is almost completely emptied. Use e.g. a brush to push the remaining fertilizer to the feeding
chambers. Turn the feeder a few rounds with the crank in order to empty the chambers. Swing the bottom
valves quickly with the lever a few times to remove any possible fertilizer remains.
Emptying the seed hopper
The seed hopper is emptied in a similar way to the fertilizer hopper.
10. USING AND ADJUSTING THE SEED FEEDING DEVICE
Overview
The seed feeder consists of threaded cylinders, bottom valves equipped with springs, and adjustable bottom
plates (figure 10). The feeding chambers are located on the bottom of the hopper. This solution enables
maintaining a stable dosage of seed despite possible tilting of the machine either sideways of towards the
driving direction. The feeding device is made of non-corrosive materials. The bottom valves under the feeding
rollers are adjustable. The adjustment lever is at the rear end, in the middle of the machine (figure 10). For
seeding fine seeds the gear ratio of the power transmission can be adjusted by turning the power
transmission cassette.
FIGURE 9. Adjusting the feed with hand wheel FIGURE 10. The feeder operating principle
Seed dosage is regulated by adjusting the feeding roller sideways in relation to the feeding chamber with the
hand wheel located on the left. The hand wheel is locked with a plastic lever, which also contains the main
feeder dosage scale of 0-10. The numbers correspond to one hand wheel round. The adjustment is read from
the inner surface of the hand wheel. The hand wheel has 10 locking positions per one turn, marked by the
numbers 0-9. This amounts to a total of 100 different adjustments. Correspondingly, when using fine seed

12
transmission (cassette position II) 100 feed adjustment positions are available in a smaller range.
NOTE! To adjust the feed, push the plastic locking lever towards the rear end of the machine
(arrow direction) and turn it simultaneously 90 degrees. This will unlock the hand wheel.
To increase the dosage, turn the hand wheel counterclockwise. When you know the suitable dosage of seed,
you can choose a normative feeder adjustment position from inside the machine cover.
Note the suitable cassette position. You should make the adjustment by approaching the desired position
always from a higher adjustment position. If the original adjustment is lower than required, turn the hand
wheel counterclockwise for 1/2 - 1 turns above the intended adjustment. After that return to the desired
position by turning the wheel.
After making the adjustment, turn the locking lever into the groove on the hand wheel to lock the wheel and
the lever. Note that the adjustments given in the seeding table are normative, and the actual dosage varies
with different lots of seeds. We recommend checking the required dosage by performing a calibration test.
If impurities accumulate in the feeding device, the cylinders may get clogged, which may considerably distort
the dosage. Regular cleaning is recommended. The cylinders can be cleaned by adjusting the dosage to zero,
and back to desired position. You should then remember the adjustment instruction given above: turn first 1/2-
1 turns over the desired adjustment position.
If the machine is equipped with a seed dressing device, the calibration test must be repeated after seeding
approximately an area of one hectare. The dressing agent may reduce the dosage amount with up to 20%!
NOTE! Do not use force to turn the hand wheel to zero position. Simultaneous turning of the
feed shaft facilitates adjustment.
Instructions for using the seeding table and performing the calibration test are provided further
below.
NOTE! The maximum speed when seeding peas and beans is 6 – 7 km/h
Turning the power transmission cassette

13
FIGURE 11. Power transmission cassette II = Grain, II = Fine seed
When the bigger sprocket of the cassette is upwards, you have a grain adjustment. When the smaller
sprocket of the cassette is upwards, you have a fine seed adjustment. The adjustment is marked on the
cassette casing to its visible side. Figure 11 shows a grain adjustment. Turn the cassette as follows: Remove
the shackle pins and pull the cassette from its axles. Turn the cassette upside down. The setting is shown on
the cassette label.
Bottom valves
The dosage accuracy depends on the distance between the bottom valve and the feeding rollers. Therefore
the correct position of the bottom valves is important, and they should not be adjusted after the calibration
test, or the test must be repeated. If a foreign object should go between the bottom valve and the feeding
rollers, the bottom valves yield.
Below we have listed advisory values for the most common seeds. If you use other seeds than those in the
list, compare their size and features to those below, and perform a calibration test with appropriate
adjustments.

11. USING AND ADJUSTING THE FERTILIZER FEEDING
DEVICE
Overview
There is an equal number of fertilizer and seed feeding chambers on the machine. Correct dosage is
regulated by adjusting the feeding rollers sideways in relation to the feeding chamber with the hand wheel
located on the right.
The feeding chambers are located on the bottom of the hopper. This solution enables maintaining a stable
dosage of seed despite possible tilting of the machine either sideways of towards the driving direction.
Feeding rollers are plastic cylinders equipped with threaded serration. The bottom valves under the feeding
rollers are adjustable. The adjustment lever is in the middle of the machine front end. The entire feeding is
made of non-corrosive materials.
All types of granular fertilizers can be fed through the fertilizer hopper. The feeder is not suited for spreading
powdery fertilizers.
Adjusting the fertilizer feed
The dosage is adjusted by turning the hand wheel on the right side of the machine. The hand wheel is locked
with a plastic part, which also contains the main feeder dosage scale.
NOTE! To adjust the feed, push the plastic locking lever towards the rear end of the machine
(arrow direction) and turn it simultaneously 90 degrees. This will unlock the hand wheel.
To increase the dosage, turn the hand wheel counterclockwise. When you know the suitable dosage of
fertilizer, you can choose a normative feeder adjustment position from inside the machine cover.
You should make the adjustment by approaching the desired position always from a higher adjustment
position. If the original adjustment is lower than required, turn the hand wheel counterclockwise for 1/2 - 1
turns above the intended adjustment. After that return to the desired position by turning the wheel.
After making the adjustment, turn the locking lever into the groove on the hand wheel to lock the wheel and
the lever. Note that the adjustments given in the seeding table are normative, and the actual dosage varies
with different lots of fertilizer. We recommend checking the required dosage by performing a calibration test.
The machine can also be equipped with electronic control devices, which are available as accessories
(AgromasterCan, Agrocont tai CE-21). Then the fertilizer side has no hand wheel, but the device is controlled
by a set of levers powered by a actuator motor.
The bottom valves are normally set to slot 2. If wet fertilizer gets into the feeder, the feeding rollers may get
clogged, which may considerably distort the dosage.
The cylinders can be cleaned by adjusting the dosage to zero, and back to desired position. You should then
remember the adjustment instruction given above: turn first 1/2-1 turns over the desired adjustment position
(form a bigger value towards a smaller one). Instructions for using the seeding table and performing the
calibration test are provided further below.
To disconnect the fertilizer feeder, remove the shackle pin from the feeder shaft end on the right end of the
machine.

12. EXAMPLES OF USING THE SOWING CHART
General
The seeding table below features three different usage examples. Note, that the dosages shown on the table
are only advisory. The actual dosage depends on the seeds in question; seed properties vary considerably
between different species and years.
To define the correct dosage, perform a calibration test, which is explained further below.
FIGURE 13. Seeding table
Adjustment example for grains
Case 1. You want to seed 200 kg/ha of oats.
• Check the correct bottom valve position in the upper right corner of the seeding table, under
"grain". The correct adjustment is "2"
• Select the graph "oats"
• Check that the machine transmission is set to "1"
• Start from the edge of table, at 200 kg/ha
• Proceed along the horizontal line to where this line intersects the graph "oats"
• Proceed straight down from this intersection to the scale which shows that the correct
adjustment is "6.8"
This means that the hand wheel should be opened by 6 full turns plus 0.8 turns. The handwheel is locked to
slot 8.

Adjustment example for fine seeds
Case 2. You want to seed 8 kg/ha of turnip rape.
• Check the correct bottom valve position, "1", in the upper right corner of the seeding table
• Look at the small seeding table
• Start from the left side of the small seeding table, at 8 kg/ha
• Move right along the horizontal line from 8 kg/ha to the intersection with graph "rape"
• Proceed straight down from this intersection to the scale on the bottom which shows that the
correct adjustment is ”2.2”
• Check the transmission rate of "II" on the upper left corner of the small table. Use the fine seed
adjustment in the power transmission, i.e. turn the cassette to the level indicated by position
"II".
Adjustment example for fertilizer
Case 3. You want to seed 500 kg/ha of NPK granular fertilizer .
• Check in the upper right corner of the seeding table, that the correct bottom valve adjustment
for granular fertilizer is "2". The fertilizer side has a factory installed sprocket Z 17.
• Start from the edge of the bigger seeding table, at "500 kg/ha"
• Proceed along the horizontal 500 kg/ha line towards the right, until it intersects with graph
"granular fertilizer Z 17", if the sprocket Z 17 is used. (black line in the chart).
• Move straight down from the intersection, to see that the correct reading of the main scale on
the adjusting wheel locking lever is "7.2". After adjustments perform a calibration test to
ensure the correct dosage.
NOTE! When aiming at an exceptionally high level of fertilization (over 700 kg/hectare), turn
the front double sprocket at the left end of the machine in order to select Z 22. It is then
possible to seed up to approximately 900 kg of fertilizer/hectare. In that case, follow the red
fertilizer line in the chart!
13. CALIBRATION TEST
General
As the adjustment levels in the sowing chart are only advisory, a calibration test must be performed before
seeding. Adjust the machine according to the seeding table prior to the calibration test.
Check the following:
• Position of the transmission cassette setting I/II
• Bottom valve adjustments (seed and fertilizer)
• Seeding amount (with the hand wheel)
• That the optional tramline device is not operational
• Fertilizer volume (with the hand wheel)
• That the bottom plates are completely open
• That the hoppers contain fertilizer and seed.
Lift the machine slightly from the ground so that the ground wheel comes off the ground and can be rolled.
The rolling is easy if you install the rotating apparatus as shown in Figure 14.The rotating apparatus is located
underneath the cover at the left end of the machine.
The pipelines of the machine (both seed and fertilizer) can easily be set to the calibration test position

17
simultaneously. To do this, you need to be in front of the machine (Figure 15).
• Lift the lock piece up.
• Push the tube racks backwards.
• Make sure that the tube rack moves smoothly and not at a slant, for example.
There are three ways to perform the calibration test:
• Simultaneously for the seed and fertilizer, in which case all power transmission pins are in
place.
• Separately for the seed, in which case you need to remove the snap ring pin from the end of
the fertilizer axel. Remember to replace the pin after the calibration test
• Separately for the fertilizer, in which case you need to remove the seed-side cassette pin.
Remember to replace the pin after the calibration test.
FIGURE 14. Ground wheel in calibration test position
FIGURE 15. Tube racks in calibration test position
The Tume Nova Combi has calibration test trays as standard equipment for both seeds and fertilizer, which

18
makes it easy to perform the calibration test.. You can keep the trays in place also during seeding. Always
remember, however, to empty the trays from dust, etc, before performing the calibration test.
When you have completed the calibration test, pull the calibration test trays out and weigh the seeds and
fertilizer in them.
NOTE! Remember to pull the tube racks back in front after the calibration test. After that the
seeds and fertilizers will be conveyed to coulters again instead of calibration test trays.
FIGURE 16. Emptying the calibration test tray
Calibration test simultaneously for fertilizer and seed
Turn the lever a few rounds to properly fill the feeding chambers. After this, empty the calibration test trays
carefully.
Turn the ground wheel for as many rounds as is specified for your machine type in the seeding table. The
rotation speed must correspond to the driving speed.
Weigh the seed and fertilizer in the seeding troughs. If the calibration test was performed with a number of
rounds that corresponds to one are, you can obtain the seeding dosage per hectare by multiplying the
weighed results by 100.
When you have performed the calibration test, retract the tube rack to the seeding position and lock the
handle lock in its place.
Put the calibration test equipment back to its place underneath the protective case.
Put the rotating apparatus of the ground wheel back in place and close the protective covers.
Using the calibration test equipment on the fertilizer side
The test is performed as described above, but you must detach the pin of the power transmission cassette
during the calibration test. Put the emptying coil in the calibration test tray underneath the fertilizer chambers.
