5.3.6. Ensuring the steerability of the tractor
The calculation of the stability of the tractor - seed drill combination is provided in the
attachment Calculating the stability of the tractor - seed drill combination. The steering response of a
small tractor may be compromised when it pulls the seed drill, because some of the weight of
the seed drill rests on the tractor's rear axle. If steering response is weak, we recommend the use
of front weights on the tractor. The tractor's weight transfer system should also be switched off,
since when using the weight control system, the height of the lifting device may change based
on the load and impact the seeding depth.
5.3.7. Adjusting the middle markers
Figure. 5.3.7. - 90. Adjusting the middle markers
1. Loosen the two screws (1).
2. Adjust the width of the marker axle (3).
3. Adjust the toe-in (2) by rotating the disc around the axle (3).
The marker should plough a furrow deep enough to be visible in the ground.
The distance between the centreline of the seed drill and the furrow made by the
middle marker should be 3 metres for the FX300 and 4 metres for the FX400.
However, the adjustment is indicative. Check the adjustment in the eld to avoid
overlapping seeding and stripes in accordance with section 6.14. Securing the
position of the middle markers. Overlapping seeding and stripes may be
generated if the operator sits at an angle in the tractor, for example.
4. Tighten the two screws (1).
