Troubleshooting Chart

Problem

Cause

Solution

Machine makes
intermittent clicking noise

Normal noise if rotor is turning with tines out
of the ground.

Normal

Rotor stalls (will not turn)

Quick couplings did not engage.

Reconnect quick couplings to skid steer.

Skid steer hydraulic flow is not engaged.

Engage skid steer hydraulics.

Traveling too fast for tilling conditions.

Slow down ground speed.

Hydraulic flow from skid steer is inadequate

Check hydraulic flow at the tiller.

Skid steer is low on hydraulic oil.

Add hydraulic oil to skid steer.

Hydraulic hose has a break.

Replace hydraulic hose.

Hydraulic hose has an obstruction.

Remove obstruction or replace hose.

Hydraulic motor is damaged.

Repair hydraulic motor.

Hydraulic line is pinched

Fix pinched line.

Hydraulic lines have air in them.

Engage hydraulics to tiller until air is
purged from hydraulic lines.

Obstacles are entangled in tines and/or rotor.

Reverse tines for 2 seconds and then
switch back to original direction may clear
obstacles. If required, manually clear rotor
and/or tines of obstacles.

Tiller makes excessive
noises or vibrates
excessively

Obstacles are entangled in tines and/or rotor.

Clear rotor and/or tines of obstacles.

End bearing is worn or damaged.

Replace end bearing.

Tines are bent or broken.

Replace damaged tines.

Tillage depth is
insufficient

Tiller is carried by skid steer.

Lower skid steer arms.

Skid steer has insufficient power.

Increase skid steer engine speed.

Tine cutting edges are not sharp.

Replace or reverse tines.

Tines are bent.

Replace tines.

Tines are incorrectly installed.

Check tine placement.

Shanks are set too deep.

Raise or remove shanks.

Obstacles are entangled in tines and/or rotor.

See last solution for “Rotor stalls”

Soil texture too coarse

Motor speed is too slow.

Ground speed is too fast.

Increase skid steer engine to full speed.

Decrease ground speed.

Soil texture too fine

Ground speed is too slow.

Increase ground speed.

Machine skips or leaves
crop residue

Tines are badly worn or broken.

Replace worn tines.

Ground speed is too fast for conditions.

Reduce ground speed.

Rotor speed is too slow.

Increase engine speed.

Direction of rotor rotation is not efficient.

Reverse rotor direction.

Tines operating behind
skid steer tires show
increased wear

Skid steer tires can compact soil causing tines
that operate in the compacted soil to have
increased wear.

Considered as normal wear.
Replace worn tines.

Tines balling up with soil

Tines are worn or bent.

Replace tines.

Tines are incorrectly installed.

Install tines correctly.

Skid steer ground speed is too fast.

Decrease skid steer ground speed.

Soil is too wet.

Wait until soil dries.

Tiller bumping on ground

Obstacles are entangled in tines and/or rotor.

See last solution for “Rotor stalls”

Tines are not installed correctly.

Install tines correctly.

Tines are worn or bent.

Replace tines.
