It may NOT
seem inconvenient and unnecessary to read and observe
the operating instructions. It is not enough to hear and see
from others that an implement is good, and then to buy it
and believe that everything takes care of itself. The person
concerned would then not only cause damage to himself,
but also make the mistake of assuming that the cause of any
problems is due to the implement, instead of himself. To
ensure success, one has to go into the spirit of things, and
instruct oneself about the purpose of all equipment on the
implement and gain experience with its handling. Only then
can one be satisfied both with the implement and oneself.
These operating instructions aim to achieve this.

5 Layout and mounting the implement
Layout and mode of operation
The multi-metering unit is a spreading and seeding unit with a capacity of 40/100
litres.
The seeding shaft is driven by a 12-V gear motor, which is regulated using the
control box. The speed of the seeding shaft can be comfortably adjusted using the
control box from the driver's seat. With the MDS version (with spreading plate),
the working width can also be adjusted from the driver's seat.
As an option, there is the possibility of adjusting the speed of the seeding shaft to the
speed of the tractor by using various speed sensors (available as an accessory).
Furthermore, tractor linkage sensors are also available as an option, which are
responsible for automatically switching on and off at the headland.
Power can be supplied to the control box either through the 3-pin standard socket or
optionally directly from the battery.
Mounting the implement
To mount the seeder on the soil tillage implement, use the
counter plate that is supplied as a standard, which can be
bolted onto the frame of various implements.
Counter plate for mounting
To attach the seeder, you should use at least 8 bolts with a diameter of 10 mm and
the required length to ensure secure and firm attachment of the implement.
Please note that that the MDS must be mounted at a height of more than 1.5 m
(delivery height of the spreading plate).

Quality for Professionals
To mount the implement on the three-point linkage of the tractor, bolt the tractor
linkage drawbar between your seeder and the supplies counter plate. You should use
at least 8 bolts with a diameter of 10 mm. Then install the supplies top link bracket
onto the frame of the spreader. Now you can attach the spreader onto the three-point
linkage of your towing vehicle.
CAUTION: APV is not liable for improper mounting or faulty use of the implement.
Installation of the baffle plates on the MDP and MDG
The baffle plates can be mounted using the standard supplied hexagon shaft or
directly (without the hexagon shaft) onto the soil tillage implement.
The following points must be noted when
mounting onto the implement (cultivator,
harrow, etc.):
•To install the baffle plates, you must
bend the "tabs" on the sides towards
the rear (approx. 80°, see Fig.: 4)
using pliers and then bolt or weld them
with the hexagon shaft onto the
implement.
•To prevent the baffle plates from sliding to the sides on the hexagon shaft,
fasten the baffle plates with a chisel and hammer (see Fig.: 5, Fig.: 6).
•The baffle plates should be evenly distributed over the entire width of the
implement, with a max. spacing of 75 cm.
NOTE: for proper distribution, the max. spacing between the baffle plates may not
exceed 75 cm. For the MDP (6 outlets), this results in a maximum working width of
4.5 m.

Quality for Professionals
•The baffle plates should have approx.
40 cm clearance from the tilled soil!
•The seed hoses should flow into the
dispersion plates vertically (90°).
Therefore, the baffle plates should
also be mounted vertically (90°) on
the hexagon shaft! (Fig.: 7).
NOTE: when hose routing, ensure that they do not have a gradient (see Fig.: 8),
otherwise the hoses can get clogged!
Fig.: 7
Fig.: 8

Quality for Professionals
Hose connection
•Slightly loosen the locking bolts (not completely)!
•Apply a little silicone spray onto the hoses (only on the outside!) to make it easier
to push them through the sealing. The hoses must be completely pushed in (until
you feel the stop) so that the seed can flow smoothly.
•Then tighten the bolts. The seal is pressed together and thus holds the hose
firmly.

Proper selection of the seeding shaft
Before filling the hopper with seed, it is important to select the proper seeding shaft
(Flex20, fine or blind).
The selection is based on the properties of the seed and the rate to be spread.
A seed wheel accessories kit is included in the standard scope of delivery for the MD:
6 x Flex20 seed wheel
12 x f seed wheel
12 x fb seed wheel
12 x O-ring 14.1 x 1.6
2 x seed metering wheel hexagon shaft

1 hexagon shaft
2 O-ring
3 f seed wheel
4 Blind fb seed wheel
5 Flex 20 seed wheel
6 Spacing discs
The number and type of the seed wheels must be the same for each outlet.
The arrangement and design of the seed wheels depends on the required spread
rate and the seed type.
This can be read from the seeding table, after the spread rate was calculated as
explained in section 6.8.
The O-ring is inserted in the groove on the hexagon shaft, and then the seed wheels
are attached.
For example: 1 fine seed wheel or: 1 Flex20 seed wheel
(per outlet) 1 blind seed wheel 1 spacing disc
1 spacing disc
This sequence is repeated until the shaft is fully equipped. Now the seeding shaft is
sealed with an O-ring.
The seeding shaft does not have a defined installation direction, since each outlet is
equipped individually.
CAUTION: it is important that the closed side of the blind fb seed wheel (Fig.: 12/4) is
always resting on the f fine seed wheel (Fig.: 12/3) and the spacing discs are placed
between the open sides of the seed wheels.
5 spacing discs must be installed for each combination.
Furthermore, the fine seed wheels must be arranged offset beside each other (Fig.:
15).

Scope of use for the Flex20 seeding shaft:
Generally for granulated fertiliser, high rates or large grain sizes.
E.g.: Grass mixtures, rye, barley, wheat, oats, etc.
Scope of use for the fine-toothed seeding shaft
Generally for low rates or small grain sizes as well as micro granules.
Small seeds such as oil rape seed, clover, phacelia, slug pellets, etc.
TIP: the spread rate can be reduced by using blind or extra-fine seed wheels.
However, ensure that the same number and type of seed wheels are installed for
each outlet!
CAUTION: it is important to select the combination of seed wheels such that the
seeding shaft settings on the control box are ideally between 20 % and 80 %.
This ensures good regulation and homogeneous delivery of the seed even with
ground speed related spreading at very low or high speeds!

Spreading width of the MDS
The spreading width depends on the
density and the shape of the seed as well
as the speed of the spreading disc. The
MDS is designed such that it can spread
seed (slug pellets) uniformly over a width of
up to 28 m. For this to succeed, the battery
and the alternator must be in good
condition. The precise settings for the
spread rate, working width etc. can be
taken from the setting chart under point
6.10. The spreader must be mounted at
least 1.5 m above the ground to achieve
optimal spreading density.
Fig.: 15
Fig.: 16

16
Quality for Professionals
NOTE: when the MDS is mounted on implements with small working widths and the
seed should be spread directly in/in front of the roller, the spreader can also be
mounted slanted slightly downwards.
However, we recommend installing a precision dispersion plate (available as an
option) to achieve more precise spreading results with small working widths up to
max. 4 m.

Point of impact adjustment for the MDS
The point of impact adjustment can be used to adjust the entire spreading pattern by
20° in both directions. This can be important for some spreading materials. For
example, if the spreading pattern is turned by 15° to the right, the point of impact
adjustment is turned by 15° to the left. If you move it further to the right, a boundary
spreading function can also be obtained.
Spreading disc, lateral distribution, and throwing vanes for
the MDS
The spreading disc must rotate counter clockwise. The spreading plate has 2
throwing vanes that are positioned not quite parallel to each other. They are only
slightly adjustable, since their arrangement and shape are already trimmed for
perfect lateral distribution. The spreading cone is only corrected using the point of
impact adjustment and the throwing vanes. To achieve optimal lateral distribution for
the selected working width, you must then still adjust the setting of the throwing
vanes on the spreading plate. When doing so, be sure to disconnect the power
supply from the control box!
To adjust the throwing vanes, loosen them and turn the
throwing vane to the required position. Then tighten all of
the bolts again!

towards "Point 1".
NOTE: the seeding shaft can only be switched on when the spreading plate is rotating!

Dismounting (changing) the seeding shaft
To dismount the seeding shaft, proceed as follows:
NOTE: when changing the seeding shaft, ensure that the hopper is completely
empty.
After installing the seeding shaft, check the implement for smooth running.
•Empty the hopper completely.
•Remove the hood on the side for the drive rollers.
•Using the socket wrench supplied on the cover, loosen the nut so that the cover
can be pulled off upwards.
•Pull the round belt off of the drive rollers (Fig.: 24).
•Screw off the locking nuts of the cover plate for the seeding shaft on the side
(Fig.: 25).
•Now remove the entire seeding shaft along with the side cover plate (Fig.: 26).
•Read the required equipment of the seeding shaft from the seeding table (Point
6.11).
•Now the new seeding shaft can be installed in the implement.
•Install the disassembled parts again in the reverse sequence.

Agitator
Use of the agitator is only required for seed
types that tend towards bridging or for very
light seed (e.g. for grasses).
When the agitator is not required, you only
have to remove the driving belt that is
spanned on the drive wheels between the
agitator and the seeding shaft.
