TOMAHAWK FAULT FINDING CHART
–
PART 1
Symptom
Fault
Possible Solutions
High power
Consumption.
Bale fed too quickly into crossbeater.
Blades too aggressive.
Worn blades or dual chop tips
Reduce bed chain speed.
Reduce aggression of blades.
Sharpen or fit new blades/tips.
Rotor won't
start.
Bale jammed hard against crossbeater.
Reverse bed chain.
Material in rotor housing jamming rotor.
Reverse rotor to clear blockage.
Slip clutch setting too low.
Check setting and adjust.
Bed chain no
longer
operates or
only very
slowly. Failure
may be
sudden or
intermittent.
Tractor hydraulic oil pressure low.
Check pressure delivered by tractor.
Relief valve setting too low.
Adjust relief valve or replace if spring worn.
Material jammed between bed chain and
bodywork.
Clear material and check bed chain tension.
Bed chain rear shaft towards end of
adjustment allowing stones to jam chain.
Shorten bed chains if sufficient space in front of
tensioner.
Bed chain has come off the sprockets.
Check sprocket grooves are clean and sprocket
condition, replace the bed chain and tension it.
Bed chain broken.
Check sprocket groove is clean and that the
chamber below the floor is free from obstructions.
Repair chain and refit.
Scraper has jammed sprocket.
Replace scraper.
Motor not turning.
Check connections and tractor hydraulics. If motor is
seized reverse flow to release. Consult your dealer if
this fails.
Sprockets seized.
Replace bearings.
Dirt or contamination in the proportional
flow slice or relief valve controlling the bed
chain speed.
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.
Slow
Discharge.
Bed chain speed too slow.
Increase forward speed of the bed chain.
Bed chain speed too slow.
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.
Material jammed hard against bale
restraint above crossbeater.
Reverse bed chain direction for at least 5 seconds until
feed is restored.
Blades / dual chop tips blunt or worn.
Sharpen, reverse or replace blades.
Rotor speed low.
Check that slip clutch is not slipping
-
indicated by hot
clutch assembly.
Check tractor tachometer.
Bale stops
discharging.
Crossbeater not rotating.
Replace shear bolt in drive sprocket.
Gearbox in neutral.
Remove material from rotor housing before
restarting and select correct gear.
Bed chain not rotating.
See solutions in bed chain section above.
Bed chain overloaded with clamp silage.
If relief valve pressure correct then reduce load size.
Fitting a larger bed motor will allow full load.
