Troubleshooting
Problem
Cause
Fixing
The harrow tracks
are not covered
properly
Discs adjusted wrongly
The discs are adjusted for work in the
surface, so that an adequate amount of
soil is thrown back towards the harrow
tine
Length of the top rod
adjusted wrongly
Adjust top rod so that the middle section
is horizontal, lengthwise
One of the
outermost side
sections are
pressing too
much/not pressing
enough
The point of complete
extent of the side section
is adjusted wrongly
The point of complete extent can be
adjusted individually for each wing on the
adjustment bolt. The stubble cultivator
must be horizontal, lengthwise as well as
in the direction of the width
Excessive wear
and tear on the
harrow tines
The driving speed has
not been adjusted to the
conditions
Normally, a working speed between 8 and
12 km/h
is
appropriate.
However,
driving
should
always
be
done
according to conditions.
Wear and tear will increase significantly
as the speed is increased
Driving speed too high
with dry conditions
At a high driving speed, especially with
dry conditions, the wear and tear on the
tines will
increase significantly
The harrow tines
deviate too easily
The accumulator
pressure in the 3D stone
control is too low
Working pressure around 70 bar = green
area on the manometer. After the
adjustments have been done, shut the ball
plug valve and the hydraulic hose can be
disconnected from the tractor.
If the ball plug valve is not shut, the oil
will slowly seep back to the tractor and
the pressure on the installation may start
to drop
Harrow tines do
NOT deviate, even
if they come
across large stones
The accumulator
pressure in the 3D stone
control is too high
The manometer may NOT be in the red
area.
Working pressure around 70 bar = green
area on the manometer. After the
adjustments have been done, shut the ball
plug valve and the hydraulic hose can be
disconnected from the tractor.
If the ball plug valve is not shut, the oil
will slowly seep back to the tractor and
the pressure on the installation may start
to drop
