Problem
Gearbox overheating
Excessive belt wear
P.T.O.. wear UJ failure
Cut Quality
Rotor bearing failure
Rotor vibration
Oil tank overheating
Break-back operating
Frequently
Excel 606, 686, 726 & 836
Cause
Oil level incorrect
Oil grade incorrect
Implement overloaded
Wrong PTO speed
Belt and pulley condition
Pulley alignment
Incorrect belt tension
Overloading of implement
Working angle to great
Shaft incorrect length I.e.
bottoming out
Lack of maintenance
Flails worn
Rotor speed/direction
Crop condition
Rotor out of balance
Wire/string in bearing
Lack of maintenance
Water in bearing
Flails broken or missing
Bearings worn or damaged
Rotor bend
Build up of debris
Incorrect speed
Oil level incorrect
Oil grade incorrect
PTO speed too fast
Ambient temperature too
high
Machine overloaded
Machine overloaded
Machine being used on
excessive incline
Weight of machine being
carried upon rear roller
Machine not set vertical
Solution
Check oil level
Check oil grade
Reduce forward speed
Ensure tractor PTO speed matches implement
Replace if necessary
Check alignment
Tension belts to spec.
Reduce forward speed or increase height of cut
Reduce offset of implements
Resize PTO shaft as recommended
Grease PTO shaft as recommended
Replace worn flails
Check tractor PTO speed
Look for suitable conditions
See rotor vibration
Remove wire/string
Grease bearings to schedule
Expel water with grease
Replace flails
Replace bearings
Re-balance/replace rotor
Remove debris
Check rotor R.P.M.
Fill tank to correct level
Drain and refill tank with correct grade oil
Ensure the tractor's PTO speed matches implement
Reduce work rate / install oil cooler
Reduce forward speed or increase height of cut
Reduce forward speed or increase height of cut
Switch off auto reset
Use Autopilot or head float
