Safety When Working Under Cutter Deck
Never work under the cutter deck until:
• The cutter is sufficiently braced and supported
• The tractor engine is off, brake is set, and key is removed
• PTO has been disengaged
• Driveline is disconnected
• Rear tractor tires have been secured with tire chocks
• The cutter is cooled
Warning! Failure to follow these safety guidelines can result in serious injury or death.
Initial Maintenance
Warning! These maintenance practices must be followed every hour for the first eight hours of
operation; the practices must also be performed every hour for the first eight hours following the
removal/replacement of any of the components named in this section. Check daily thereafter.
1.
Tighten the bolts and tapered shank keeper bolt holding the slip clutch to the input shaft of the gear box.
Caution! Failure to tighten the keeper bolts will shorten the life of the slip clutch hub.
2. Check for debris deposited between the blade bar and the blades. Debris found jamming or locking
the blades must be removed to insure that the blade may pivot freely on the blade bolt.
Warning! Failure to maintain freely pivoting blades will cause severe vibration or blade breakage
which can result in injury or death.
3. Tighten blade bolts and blade bar nut.
Warning! Failure to tighten blade bolts and blade bar nut can cause blade bolts, blades, or output
shafts to break, which can result in injury or death.
4. Check for debris deposited around the output shaft or tail wheel axle.
5. Tighten gearbox mounting bolts.
Caution! Failure to keep the gearbox bolts tightened can cause the blades to strike the bottom of the
cutter deck or break the output shaft of the gearbox.
Daily Maintenance
1. Repeat all steps listed under the “Initial Maintenance” section on a daily basis after the initial
maintenance has been performed.
2. Lubricate the driveshaft tubes and U-joint.
3. Lubricate the tail wheel hub.
4. Check and maintain the proper amount of lubricant in the gearbox.
The recommended lubricant
for the gear box is SAE 85-140 weight gear oil or equivalent.
5. Check the blades; sharpen or replace as necessary.
When sharpening blades, only sharpen the
beveled edge. Also, be certain that paired blades weigh within 1 oz. of each other. When
replacing blades, replace both blades of the pair.
