7. MACHINE SETTINGS
The Overseeder 3D has several options for setting the machine optimally.
7.1 Adjusting the working depth
The working depth can be adjusted by turning the top rod.
If the top rod is turned, causing it to be shortened, the machine will rotate forward and the result is that
the sowing depth is set deeper.
This works if the ground that should be treated is sufficiently soft to be cut.
If the ground is too hard, the machine can also be constructed more heavily by additional weight sets
(see Section 12.1) and/or by filling the rear roller with water to obtain the correct sowing depth.
If the rear roller is filled with water, remove it before it starts to freeze!
7.2 Setting the seed-element valves
The machine is suitable for sowing different types of seeds. Furthermore, the seeder can also be used
in combination with various tractors and you can sow at different speeds. To adjust the machine to the
various factors, the machine’s sowing installation must be adjusted. The seed elements have a
number of functions (see Figure 4b):
1. If the seed-element valve is closed, no seeds can flow out of the hopper when the
machine is idle (e.g., during transport).
2. To empty the hopper after sowing, the valve (a sowing element) can be opened so
that the seeds can run out of the hopper.
3. The seed-element valve can be adjusted according to the size of the seeds that will be
sown. In case of fine grass seed, the element valve must be closed completely. Then
the gear wheel grabs the seeds. In the case of larger seeds, the space between the
gear wheel and the valve is not large enough to let the seeds pass. Therefore, the
valve needs to be opened more for larger seeds. Adjusting the size of the opening can
be done using the valve adjustment handle. The handle can be adjusted by loosening
the stellar knob (1), selecting the required position by means of the indication sticker
(2), and retightening the stellar knob (see Figure 4a).
Figuur 4a Figuur 4b
7.3 Setting the quantity of seeds using the gearbox
By affecting the setting of the seed elements, the delivery of seeds can be set to additional or fewer
seeds. Each seed element contains a rotor that transports the seeds. By affecting the speed of the
rotors, the quantity of seeds can be adjusted. The gearbox can continuously variable adjust the speed.
Do the following to adjust the quantity of the seeds:

13
1. Loosen the stellar knobs (1) (see Figure 5).
2. Rotate the stellar knob (2) to change the settings. You can see the settings on the
sticker (3).
3. Retighten the stellar knobs (1).
Figure 5
7.4 Dispensing test
The quantity of seeds should be adjusted for the correct operation of the Overseeder 3D. See the
Tables 1, 2 and 3 for an indication of the required quantity.
You should consider the following instructions for this:
!! Make sure that the Overseeder 3D is standing on its legs and is detached from the
tractor (see Section 6.2) !!
You will need the following accessories for adjusting the quantity of seeds:
1. A scale
2. A tray for weighing the seeds
3. Enough seeds for filling the hopper for minimum 30%
The procedure is as follows (see Figure 6):
1. Set the flap of the seed-element valves (4) to 0.
2. Fill the hopper with seeds and make sure that these are evenly spread throughout the
hopper.
3. Loosen the stellar knob (1) and slide the seed dispensing bin (2) out of the machine.
4. Rotate the seed dispensing bin 90° and slide it back into the machine.
5. Turn the wheel (3) 13 rotations counter-clockwise.
6. Remove the seed dispensing bin (2) out of the machine and collect the seed in a tray.
7. Weigh the seeds in kilograms and multiply the outcome by:
Overseeder 3D 1275: 474
Overseeder 3D 1575/1575LV: 384
Overseeder 3D 2075: 291
The resulting outcome is the amount of seeds in kilograms that should be spread per hectare.
To obtain the outcome in pounds per acre, multiply the resulting outcome by 0.89.
!! Attention !! If the bin is in a high position, it may cause the release of a large quantity
of seeds. Then divide the 13 rotations in several smaller steps!

8. TRANSPORT
The user is responsible for transporting the machine on public roads.
Verify the national legislation regarding the regulations. Related to the weight of the machine, it is
recommended not to drive faster than 20 km/h (12.4 mph) with a lifted machine. A higher speed can
be dangerous for the driver and/or the public and can even damage the machine.
!! When the machine is raised off the ground, the front axle of the tractor has to support
minimum 20% of the tractor’s weight !!

18
9. PUTTING THE MACHINE INTO OPERATION
9.1 Safety
Before using the Overseeder 3D, you should check the following:
1. Are there loose objects in the field? First remove these objects.
2. Are there slopes? The maximum slope is 20 degrees for this machine. Always go from top to
bottom.
3. Are there hard objects in the ground? If so, use the Overseeder 3D at adjusted speed.
4. Is there danger of flying objects (e.g., golf balls) that distract the attention of the driver? If so,
the Overseeder 3D CANNOT be used.
5. Is there danger of sinking / sliding away? If so, postpone the work activities.
6. If the soil is frozen or very wet, postpone the activities until conditions improve.
7. Check whether the hopper is not too damp. Dampness can cause the seeds to stick to each
other and this leads to a poor result.
8. Do NOT make sharp curves when the Overseeder 3D touches the ground.
9.2 Working speed
The maximum safe working speed of the machine is approx. 12 km/h (7.5 mph). However, the user should
check which speed is optimal to achieve the required result per individual situation and soil treatment.
9.3 General remarks for using the Overseeder 3D
−A field can be treated two or three times in different directions in order to obtain a
higher sowing density.
−Do NOT make sharp curves and preferably drive in straight lines to prevent damage to
the machine and the ground.
−If a hard object in the ground is hit, the knives can get damaged. In that case, try to file
the burrs or replace the knives.
−If the knives get damp, seeds can stick to each other and accumulate between the
knives.
−Try to make sure that the knives do not get damp or postpone sowing until the
conditions are better.
−NEVER drive in reverse when the machine stands on the ground.
9.4 Start / stop procedure
Before starting to sow, check the following points:
!! Make sure that the machine and the tractor cannot move while you are detaching
them !!
!! Switch off the tractor engine before detaching the machine !!
−Check the knives for damage and repair them, if necessary.
−Check whether the passageway to the sowing elements is not blocked (funnels,
sowing pipes, etc.).
−Check whether the machine is not wet or damp, predominantly in the sowing system.
−Check the ‘image’ of the sowing by rotating the runner once (counter-clockwise).
−Check whether the drive runs smoothly.

19
STARTING TO SOW
The start procedure is VERY important. If this procedure is not executed as described below, it might
result in serious damage to the machine. The procedure is as follows:
1. Put seeds in the seed container.
2. Set the required dose of seeds by adjusting the gearbox (see Section 7.3).
3. Move to the location where you want to start.
4. Start at a speed of approx. 3 km/h (1.9 mph).
5. While driving, lower the machine gently and in a controlled manner, until the
sowing elements cut into the ground.
6. Increase the speed until the correct drive speed is achieved.
STOPPING TO SOW
1. Decrease the driving speed to approx. 3 km/h (1.9 mph).
2. While driving, lift the machine off the ground.
3. Go to the next location and start again as described above.
It is absolutely necessary to work according the aforementioned procedures. If the
machine is put into the ground in a non-operating position, serious damage to the
machine might occur.
While driving, lower the machine carefully and in a controlled manner during treatment.
NEVER drive in reverse when the machine stands on the ground.
