Possible Solutions
Reduce bed chain speed.
Reduce aggression of blades.
Sharpen or fit new blades/tips.
Reverse bed chain.
Reverse rotor to clear blockage.
Check setting and adjust.
Check pressure delivered by tractor.
Adjust relief valve or replace if spring worn.
If relief valve pressure correct then reduce load size.
Fitting a larger bed motor will allow full load.
Clear material and check bed chain tension.
Shorten bed chains if sufficient space in front of
tensioner.
Check sprocket grooves are clean and sprocket
condition, replace the bed chain and tension it.
Check sprocket groove is clean and that the
chamber below the floor is free from obstructions.
Repair chain and refit.
Replace scraper.
Check connections and tractor hydraulics. If motor is
seized reverse flow to release. Consult your dealer if
this fails.
Replace bearings.
Remove the proportional cartridge and relief valve from
the flow control slice inspect for contamination clean
and replace. If problem persists or re occurs regularly
replace tractor hydraulic oil with new clean oil.
Fit inline filter kit.
Increase forward speed of the bed chain.
Insufficient oil flow from tractor. Check oil level on
tractor and/or adjust flow rate. Consult dealer if
hydraulic flow cannot be controlled using tractor valve.
See handbook for recommended speeds.
Reverse bed chain direction for at least 5 seconds until
feed is restored.
Sharpen, reverse or replace blades.
Check that slip clutch is not slipping - indicated by hot
clutch assembly.
Check tractor tachometer.
Replace shear bolt in drive sprocket.
Remove material from rotor housing before
restarting and select correct gear.
See solutions in bed chain section above.
