Troubleshooting Problems
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
Increase turning radius to reduce PTO angle
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
Remove wire/string
Grease bearings to schedule
Expel water with grease
Rotor Vibration
Flails broken or missing
Bearings worn or damaged
Rotor damaged / bent
Build up of debris
Incorrect speed
Replace flails
Replace bearings
Re-balance/replace rotor
Remove debris
Check rotor RPM
Tractor external oil
supply
overheating/not
staying in detent
High back pressure in returns line
Too much oil flow
Connect implement return hose to a free flow
returns on tractor
Reduce to 45lt/per min or less
Control levers
stiff/not operating
Cables trapped, rusted or snapped
Ensure cables are routed correctly
Keep levers covered when not mounted on
tractor
Slip clutch excessive
slip
Friction discs worn
Bearing or drive line failure
Replace friction discs
Check drive train for free smooth running
Wide angle PTO joint
premature wear
Tractor & implement turning at too
sharp an angle
Lack of maintenance
When turning at a sharp angle disengage PTO
Refer to service schedule
Decks dropping
Ram seal leaking
Cable sticking/out of adjustment
Control valve worn
Replace ram seals
Replace/adjust cables
Replace control valve
