Problem
Cause
Solution
Oil level incorrect Check oil level
Gearbox overheating
Oil grade incorrect
Check oil grade
Implement overloaded
Reduce forward speed
Wrong PTO speed
Ensure tractor PTO speed matches implement
Belt and pulley condition Replace if necessary
Excessive belt wear
Pulley alignment
Check alignment
Incorrect belt tension
Tension belts to spec.
Overloading of implement
Reduce forward speed or increase height of cut
Working angle to great Reduce offset of implements
P.T.O.. wear UJ failure
Shaft incorrect length I.e.
bottoming out
Resize PTO shaft as recommended
Lack of maintenance
Grease PTO shaft as recommended
Flails worn Replace worn flails
Cut Quality
Rotor speed/direction
Check tractor PTO speed
Crop condition
Look for suitable conditions
Rotor out of balance See rotor vibration
Rotor bearing failure
Wire/string in bearing
Remove wire/string
Lack of maintenance
Grease bearings to schedule
Water in bearing
Expel water with grease
Flails broken or missing Replace flails
Bearings worn or damaged
Replace bearings
Rotor vibration
Rotor bend
Re-balance/replace rotor
Build up of debris
Remove debris
Incorrect speed
Check rotor R.P.M.
Oil level incorrect Fill tank to correct level
Oil grade incorrect
Drain and refill tank with correct grade oil
Oil tank overheating
PTO speed too fast
Ensure the tractor's PTO speed matches implement
Ambient temperature too
high
Reduce work rate / install oil cooler
Machine overloaded
Reduce forward speed or increase height of cut
Machine overloaded Reduce forward speed or increase height of cut
Break-back operating
Frequently
Machine being used on
excessive incline
Switch off auto reset
Weight of machine being
carried upon rear roller
Use Autopilot or head float
