Troubleshooting
Problem Cause Solution
Gearbox Overheating
Oil level incorrect
Oil grade incorrect
Implement overloaded
Wrong P.T.O. speed
Check oil level
Check oil grade
Reduce forward speed
Ensure tractor P.T.O. speed
matches implement.
Excessive Belt Wear Belt and Pulley condition
Pulley Alignment
Incorrect belt tension
Overloading of implement
Replace if necessary
Check Alignment
Tension belts to spec.
Reduce forward speed or
increase height of cut.
P.T.O. wear UJ failure Working angle too great
Shaft incorrect length i.e.
Bottoming out
Lack of maintenance
Reduce offset of implement
Resize P.T.O. shaft as
recommended
Grease P.T.O. shaft as
recommended.
Cut quality Flails worn
Rotor speed/Direction
Crop condition.
Replace worn flails
Check tractor P.T.O. speed
Look for suitable conditions.
Rotor bearing failure Rotor out of balance
Wire/string in bearing
Lack of maintenance
Water in bearing.
See rotor vibration
Replace bearings
Re-balance/replace rotor
Remove debris.
