correct operation and exploitation of the spreader. Careful observance of the recommendation
included in the Manual will ensure safe and efficient machinery operation. In case of any problems
or doubts related to operation and
exploitation, please contact with an authorized seller or the manufacturer’s Sales Department.
I. OCCUPATIONAL HEALTH AND SAFETY
1. During any works carried out on the spreader’s mechanisms, that are jointed with a tractor
via a shaft, you need to turn the tractor’s engine off and take the key out of the ignition switch.
2. You must not operate or travel on the spreader or its drawbar when covers of mechanisms
and jointed-telescopic shafts are removed. Furthermore, you must not exceed the permitted
speed.
3. You must not leave the spreader on inclined surfaces or slopes without activating a
handbrake and securing the travel wheels with wedges.
4. It is dangerous to remain at the spreader’s back side during its operation as the manure may
contain various items, such us stones, wood, bricks, etc.
5. You need to be careful during any disassembly works, not to cause body injuries. In case of
injury you need to clean the wound immediately, disinfect it with hydrogen peroxide solution
and contact a doctor. An injured sport that is contaminated with manure can lead to infection
with tetanus bacteria.
6. Exceeding a permissible loading capacity can damage the machine and cause an accident
on the road.
7. You must not use the floor conveyor to unload heavy materials, such as rubble, gravel, sand,
etc.
8. Machinery operators shouldbe trained in the scope of applicable OHSand the HighwayCode
principles.
9. You need to observe all recommendations included in the Manual, and take special care in
doubtful cases.
10. Before you hit a public road you need to clean the machinery lights and attach a vehicle
marking plate on its rear side.
11. A manure spreader without a braking system, should be equipped with:
- wedges to be
placed under
wheels,
- security chains - if a spreader’s catch uncouples from the tractor’s
catch,
12. You must not load or unload the spreader (trailer) if it’s not coupled to the tractor.
13. When you go up and down the spreader use the intended safe ladder - with proper length
and location.
14. Whencarrying out assembly and disassemblyactions, you must always place the supporting,
safety devices and ladders in a position guaranteeing operational safety.

II. LIMITATIONS RELATED TO TRAVELING ON PUBLIC ROADS
The manure spreader is equipped with electric and pneumatic installations. It’s adjusted to
traveling on public roads with a tractor.
There is a bracket for a vehicle marking plate to be installed on the machinery’s rear side.
If you don’t have a vehicle marking plate, you can buy it in a manufacturer’s store.
NOTE: Before you hit the public roads you must connect the electric and pneumatic
installations wire of the spreader to the tractor, clean the
machinery’s lights and marking, check operation of the lights
and brakes. While traveling, you need to:
- follow the Highway Code regulations,
- restrain from exceeding the permitted speed of 25 km/h.
III. AGGREGATION, LOADING, TRANSPORTATION
1.
The machinery can be aggregated only to especially intended devices
2.
Take special care while aggregating the machinery!
3.
Before you uncouple the machinery, secure it against rolling down (a parking brake,
wedges under the wheels).
4.
The vehicle can be started-up only when safety devices are properly attached and
adjusted!
5.
There is a danger of tilt if the machinery is loaded unevenly, especially after uncoupling it
6.
If the machinery is loaded only partially, you may have certain difficulties with maneuvering
the tractor. In such a situation you must be especially careful while traveling.
7.
Remember that the tractor’s front axis is relieved, thus controllability of the vehicle is
hindered because of the load.
8.
Take additional load of the axis and total weight into consideration.
9.
Danger of tilting!
You can operate the spreader if the lateral surface inclination does not exceed 10°.
10.
Activate a proper gear while traveling down the slope (the same as the one that is
activated while going up the slope).
IV. FIRST START-UP AND RUNNING-IN OF THE MACHINERY
Before you start up the spreader for the first time, you need to:
- read and understand the Manual,
- complement the machinery regarding type of work,
- make sure that all screws are tightened and all chains are tense,
- lubricate or lubrication points according to table 4,
- carry out initial running-in of the spreader without load, in a parking position.
The running-in process must take two hours, including decreased rpm of the tractor’s drive during
the first hour. During the running-in process you must observe carefully whether the mechanisms
work smoothly, without any jams, cracks or excessive noise. When the initial running-in is completed,
make sure that the fixing bolts are tightened and the chains are tense. Remove all faults that you
notice. Final running-in process takes place within two days of operation, when all lubrication points
must be lubricated twice a day. When the running-in process is completed you need to check the oil
level in the gearbox and make sure again that all bolts are tightened and chains are tense.

5.2. Floor conveyor.
The floor conveyor is composed of closed chains connected via strikes, constructed from a hot-rolled
channel bar (Fig. 4).
The conveyor is driven by a hydraulic engine and a hydraulic transmission installed on the spreader’s
right side. The feed rate (dose) is adjusted in a stepless way, witha oil flow regulator, whichis located
above the spreader’s drawbar. The conveyor can feed forwards and backwards.
The conveyor is tensed with pressure springs, which at the same time play an amortization role, and
which must be pressed properly. Detailed information about the stretcher are described in point
6.4.3.

Mechanism adjusting tension of the chains, individually for each chain, are located in the
front part of the load-carrying body.
When the conveyor feeds forwards (towards the tractor), you must be
careful so the moved material does not damage or push the front wall of
the load-carrying body.
The floor conveyor can be controlled only during its operation.
5.3. Braking system.
The manure spreader is equipped with a braking system, including:
-service brake - of a pneumatic type, controlled from the tractor’s driver cab
-parking brake - hand, started with a crank located at the front part of the trailer Distribution
of particular elements of the braking system is presented in Fig. 5 scheme.

The service brake, with rated load on the trailer, according to the Highway Code regulations, allows
to reach a delay in braking of at least 2.5 m/s2, with braking distance below 10 m. The auxiliary
parking brake holds the spreader uncoupled from the tractor on a surface inclined at up to 16%
(elevation or drop). Structure of the braking system ensures automatic activation of brakes of both
wheels in case of unexpected uncoupling of pneumatic installations of the trailer and tractor.
5.4. Hydraulic installation.
The hydraulic installation is coupled to the tractor with AGRIC push-in fittings. There are two
options of coupling, depending on how manypairs of hydraulic sockets the tractor is equipped with.
In a standard version there are two pairs of fittings, and in the second versions there is a possibility
to install a hydraulic divider to control particular hydraulic devices via a single pair of fittings.

6. Machinery utilization and adjustment for work.
6.1. Machinery preparation and adjustment for work
The spreader is sent from the facility completely assembled, adjusted for manure spreading. While
preparing the spreader for work, you need to couple it to the tractor.
For that purpose, you need to place the drawbar at the tractor’s catch level (a catch for single-axis
trailers) using an adjustable support screwed to the front part of the frame. When the spreader is
coupled and the tractor’s catch is locked, you need to rotate the crank 4, which moves the movable
part of the support upwards or downwards, until you feel resistance. If the obtained clearance is
too small, you can free the flange 3 through removingthe pin 5, and place it in an intended transport
position.
While uncoupling the machine when the work is done, the actions related to adjustment of the
support must be repeated in a reversed order.

6.3. Loading and unloading the trailer.
The trailer should be loaded with a crane, loader or conveyor. The load should be
distributed evenly throughout the whole surface of the load-carrying box floor. Loading of the
manure (peat or compost) should be realized from the rear to the front side of the trailer, what
exerts positive influence on quality of later spreading. Loading of other materials with utilization of
the trailer as a transportation mean, should take place in a reverse order, i.e. from the front to the
rear side of the trailer. While transporting loads that exert significant point pressure on the load-
carrying box floor, what should be avoided, you need to lay thick planks on the surface, providing
surface load, and protecting from damaging the floor and chain conveyor.
6.4. Principles of correct use of the machinery.
6.4.1. Adjustment of the manure dose.
During the fertilization process, the machine’s floor conveyor feeds in direction that is
opposite to the direction of travel, from the tractor to the spreading adapter. The conveyor can
feed in the other direction only in special circumstances, i.e. the machine is clogged or there is a
procedure of cleaning the spreading rollers from foreign elements, but not more than 30 cm.
The conveyor feeding direction depends on the hydraulic oil flow direction through the system,
and the feed rate is adjusted in a stepless manner, with a flow rate hand wheel.
There should be no pressure in sockets and plugs of the push-in fittings during
the coupling process. The coupling must be strong and reliable.
When the work is done, disconnect the cables in a reverse order.
6.4.2. Spreading adapter
Safety and reliability of the adapter’s operation depends to a significant extent on foreign
bodies located in the manure (e.g. stones, wood, etc.). Furthermore, strings present in the manure
can wrap the spreading rollers, causing a drop in the adapter efficiency. The entangled strings
must be immediately removed, otherwise a failure can occur. The wrapped string must be removed
with a sharp tool.
The adapter should be installed on the spreader’s frame with a crane. For this purpose, connect
hooks of the sling with the adapter’s catches located in its upper part.
If the spreading adapter is blocked, you must turn the hydraulic drive of the
floor conveyor off.
Bearing in mind significant oil pressure, which is necessary for proper operation
of the machine, the tractor must have a working system of external hydraulics
and a proper oil level.
A4VS and A2VS vertical adapters
The spreader can be equipped with two kinds of horizontal adapters, four-roller A4VS and two-
roller A2VS. The four-roller vertical adapter has spreading drums, inclined at a level of 15°. Two
internal drums have smaller diameter than the external drums, what causes lower rotational
speed of cutting knives located at the circumference, and this better break-up of the manure. The
two-roller vertical adapter has two spreading drums with a large diameter, inclined at the level of
15°.
Bigger diameter causes bigger working width. Worn-off knives can be replaced with new

Operating Manual
TYTAN premium
- page 16 -
ones. The drums are embedded on an intersecting axis gear with flexible clutches, and bearing
mounted from the top in ball bearings. The manure fed by the floor conveyor is received by the
rollers and spread on the field. While working with a vertical or horizontal adapter, the damper must
be taken maximally upwards. Safety and reliability of the vertical adapter’s operation depends to
a significant extent on foreign bodies located in the manure (e.g. stones, wood, etc.). Furthermore,
strings potentially present in the manure can wrap the spreading drums. The entangled strings
must be removed at they can lead to lower quality of manure spreading. The wrapped string must
be removed with a sharp tool. The adapter should be installed on the spreader’s frame with a
crane. For this purpose join the sling hooks with the adapter’s catch, located in its upper part, and
place it on guide pins of the spreader’s frame, and lock the locks coupling the adapter to the
machinery.
The shut-off valve is located on the adapter’s right side. It protects the rear cover of vertical
rollers from unexpected dropping during repairs and removal of foreign bodies, i.e. stones,
strings, etc.
The four-roll adapter is intended mainly for spreading manure.
The two-roll adapter has two discs, 950 mm in diameter each, which support sowing of loose
materials. This adapter can be utilized for manure, peat, chicken manure and lime spreading.
NOTE: Utilization of the two-roller vertical A2VS adapter for sowing of lime,
significantly increases consumption of the adapter’s working elements.
It is recommended to spread lime with a disc adapter.
Vertical disc adapter
The disc adapter is constructed from two discs with blades, three gearboxes with bevel
gears. There is a horizontal adapter - equipped with two horizontal spreading drums - located
above the disc adapter. Its task is to break up larger particles of the material falling on the
spreading discs. Threading of the worms is located symmetrically on the drum in such a manner
that the fertilizer is drawn inside the adapter during the spreading process. It is embedded in a
tight housing, and it rotates counter-clockwise to the direction of the floor conveyor feed. The
lime or fertilizer fed by the floor conveyor is broken up into fine particles by cutting knives, and
thrown on the spreading discs. While working with manure or compost, the rear damper must be
lifted maximally.
While working with lime or other loose material, the damper is opened at the height
of automatic piling of the fertilizer.
This adapter cooperates with a disc adapter, which spreads the falling and fermented
manure (compost), peat, sludge, chicken manure and lime.
Volumetric adapter
The volumetric attachment is constructed from two side walls and a hydraulically lifted flap. If
you want to mount the attachment, you need to demount the damper. Put the plugs of
hydraulic hoses of the attachment into the socket located on the pole at the right side of the
machinery.
Demounting the rear wall / damper
1. Lift the damper maximally upwards with the hydraulic means.
2. Attach the slings of the lifting device in the damper’s catches.
3. Remove the cylinder’s eyes from the damper’s pins.
4. Remove the damper from guides.
5. Lower the cylinders hydraulically to a bottom position

Operating Manual
TYTAN premium
- page 17 -
Dose of the spread manure depends on:
- feeding speed of the floor conveyor, resulting from the hydraulic oil flow rate through the
flow adjuster.
- spreader’s speed of travel on the field;
- volume weight of the applied fertilizer;
- working width;
Indicative values of fertilization in tones per one hectare (t/ha) are provided in the table on pages
23 - 26.
NOTE:
While spreading the manure, the load-carrying box’s damper must be lifted maximally with
hydraulic cylinders. Partial opening of the damper can cause certain resistance during
transportation of manure towards the adapter, causing damage to the conveyor, pushing the
damper out of the guides or damaging the hydraulic cylinders lifting the damper. The damper can
be opened partially while spreading loose materials; the minimum gap should be 400 mm.
While spreading manure, peat or compost use only lower
floor conveyor feeding speeds, in the range between 1 to 10 on the flow adjuster scale. If you
want to increase the dose of spread material, lower the working speed.
Higher speeds (10-12) serve for automatic unloading of the trailer. In order to get
the best spreading parameters (widths and uniformity) rotations on the tractor’s PTO should be
kept at the level of 520 - 550 rpm.
Lower rpm in the spreading procedure causes a significant drop in the machine’s working
parameters.
The ladder fixed at the load-carrying box’s side enables access to the interior in order to control
the filling level or carry out operational and repair activities.
6.4.3. Adjustment of the conveyor chains tension.
While utilizing thespreader, and first of all in the initial period, you must pay special attention
to maintenance of a proper tension of the conveyor chains. Backlash of the chains visible while
raising them perpendicularly to the direction of movement, at the half length of the load-carrying
box, should be as low as possible. Adjustment is realized via stretchers located in the machine’s
front part.
Fig. 11
Mechanism for tensioning chains of the floor conveyor.
If the work range of the stretcher does not allow further tensioning of the chain, you need to remove
a proper number of the chain links. You shorten the chain by cutting off at least two chain links,
multiplying the number in case there is a need to shorten the chain more. Always remove the same
number of links from all chains.

6.4.4. Adjustment of brakes (Fig. 5)
The brakes are adjusted separately from each of the four wheels of the trailer.
In order to check for backlash and adjust the brakes, you need to:
couple the spreader with a tractor and secure the tractor from rolling down; lift
the wheelset axis with a hoist;
protect the trailer against dropping and release the wheels’ brake;
using the handbrake crank 1, via the strings 2, shift the arms of the brake expander by 1/3 of
maximum movement, two wheels of the trailer should be braked then; carry out an analogical
action for the remaining wheels of the trailer, using a pneumatic cylinder;
if shift of the arms of the brake expander necessary to brake any wheel exceeds 1/3 of the
maximum movement, you need to adjust the brakes by changing mutual position of toothed bars
on brake expanders; in order to do it you need to partially untighten the castellated nuts tightening
the toothed bars;
when the adjustment is completed, press the toothed bars with castellated nuts and secure with
new cotter pins.
NOTE!
If the brakes are adjusted properly, the aggregate (tractor + trailer) with rated load, traveling at a
speed of 20 km/h, should stop at the distance of 10 m from the beginning of braking, while both
wheels should brake evenly. Having traveled the first 100 km, you must check and possibly adjust
the machine’s brake.

6.4.5. DRIVE THROUGH JOINTED SHAFTS
1.
Mounting and demounting of the jointed shaft can be
carried out only when the motor is turned off and the
key is taken out of the ignition switch!
2.
You must never turn the jointed shaft on if the motor is turned off!
3.
Nobody can be present near the working jointed
shaft!
4.
Take care of attachment and adequate condition of the protection pipe and the jointed
shaft cover!
5.
It’s possible that after turning the motor off, the
aggregate will be working due to force of inertia. You
must not approach the machine in such a situation.
Works on this part can be carried out only after the
drive is immobilized.
