Troubleshooting Chart
Problem
Cause
Solution
Disc Harrow makes a high
center ridge.
Disc blades are moving too much soil to
the center.
Tilt Disc Harrow up at the rear by
shortening the center 3-Point link. See
“Disc Leveling Front To Rear” on page 15.
Decrease tractor speed.
Increase spacing between disc gangs by
moving all gang hangers on both sides
away from the center equal amounts.
Disc Harrow cuts a furrow
(valley) in the center.
Disc blades are not moving enough soil to
the center.
Tilt Disc Harrow down at the rear by
lengthening the center 3-Point link.
Increase tractor speed.
Reduce spacing between rear disc gangs
by moving all gang hangers on both sides
toward the center by equal amounts.
Disc Harrow makes ridges on
the out side cuts and furrows
just inside the ridges.
Too much soil is thrown out by the front
disc gangs.
Check front to rear disc leveling. Raise
front disc gangs by lengthening the center
3-Point link.
Reduce front disc gang angle by one
position.
Disc Harrow makes a furrow on
the out side cuts and a ridge
just inside the furrow.
Rear disc gangs are set too wide and picks
up soil beyond where the front gangs throw
it out.
Reduce spacing between rear disc gangs
by moving all rear gang hangers in toward
the center equal amounts.
Raise front disc gangs by lengthening the
center 3-Point link.
Disc Harrow does not pull
straight and/or shifts from side
to side.
Front disc gangs run deeper than the rear
disc gangs.
Tilt Disc Harrow down at the rear by
lengthening the center 3-Point link.
Disc gangs are not centered on the frame.
Center disc gangs on the Disc Harrow.
Front disc gangs not at the same angle.
Set Front disc gangs at the same angle.
Rear disc gangs not at the same angle.
Set Rear disc gangs at the same angle.
Disc Harrow leaves a
depression in the worked soil
behind tractor wheels
Tire slippage, heavy tractor, soft soil
conditions.
Add duals, increase tractor speed,
increase gang angle and/or increase
cutting depth.
Tilt Disc Harrow down at the rear by
lengthening the center 3-Point link.
Disc Harrow won’t settle down
and operate smoothly.
Disc gang angles are set too high.
Set disc gang angles at the smallest angle
required to do the job. Make sure front disc
gangs are set 3 degrees higher than the
rear disc gang angles.
Disc Harrow does not penetrate
soil properly.
Disc gangs are not set at enough angle.
Increase disc gang angles. Make sure the
front disc gangs are set 3 degrees more
than the rear disc gangs.
Outside front disc blades and/or
gang axle is bending or
breaking.
Making sharp turns and crossing ditches
with Disc Harrow in the ground.
Raise Disc Harrow out of the ground when
making sharp turns and crossing ditches.
Do Not cross deep ditches.
Gang axles become loose
Keep disc gang axle nuts tight. See
“Additional Torque Values”
on page 26.
