Problem/Fault
Potential Cause
Solution
Difference between the
adjusted and real spread
amounts or deviations
occur
Disturbed field surface
Take care to prepare a uniform seed bed to avoid deviation
in the spread amounts since the high vibration will cause
deviations in the number of wheel rounds.
Incorrect throttle/slide
cover adjustment
Adjust the throttle and slide cover according to the seed
size.
Incorrect transmission oil
selection
The viscosity of the transmission oil no. 140 changes to
adversely affect the function of the cams inside the
transmission at low temperatures. Thus, oils such as
80W90 (W: Winter) suitable for winter conditions when the
temperature is low must be preferred.
Incorrect hopper gear
adjustment
Adjust the gear position according to the type of seed to be
planted.
Calibration fault
Make the calibration in accordance with the instructions
set out in the user manual and exercise due care. Use
correct coefficient during calibration.
Scaling fault
Ensure that the scale you are using measures
correctly and that you place the scale on a smooth
surface and determine the tare before scaling.
Transmission failure
Contact with the service.
Deviations in row
spacing
Shift in the coulters
Reset the row spacing of the coulters.
Wear and fatigue in triangle
rubber chocks
Replace the chocks.
Sagging in the coulters
Wear and fatigue in triangle
rubber chocks
Replace the chocks.
Seed remains uncovered
in tractor wheel tracks
Seed bed is left rough
Settle the seed bed by means of a roller.
Incorrect seeding depth
Increase the seeding depth.
The box cover is
opened due to vibration
The lock tension spring is loose
Switch the lock tension spring to the next slot on the scale.
The automatic cover
does not open. It
does not stay still
when it is open.
Gas pistons are worn out
Replace the gas pistons.
Too much/little
clearance remains
between two passages.
Markers are not properly
adjusted
Ensure that a distance equals to the drill’s working width
exists between the marker discs and the drill’s center.
Difference between the
coulters and the
spread amount
Different position adjustment
between the slide covers
Check whether all the slide covers are in the same position
and aligned.
