SEASONAL CLUTCH MAINTENANCE
It is important that the clutches slip when an obstacle or load heavier than the clutch setting is encountered.
Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or humid air it is
important to make sure that the clutch lining plates are not rusted/corroded together. Before using the cutter
use the following procedure to make sure the clutch will slip and give the overload protection required.
1. Loosen nuts (Figure Mnt-R-0090) on springs until the springs are free, yet remain secure on bolts.
2. Attach cutter to tractor and start the tractor. Set the engine speed at 1200 RPM.
3. Mark outer plates as shown in Figure Mnt-R-0090.
4. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates
should break loose (check the mark).
5. Turn tractor off. Tighten the nuts on the disc spring clutch until Belleville spring is flat, then loosen each nut
2 turns.
STORAGE
Your rotary cutter represents an investment from which you should get the greatest possible benefit. Therefore,
when the season is over, the cutter should be thoroughly checked and prepared for storage so that a minimum
amount of work will be required to put it back into operation for the next season. The following are suggested
storage procedures:
1. Thoroughly clean the cutter.
2. Lubricate the cutter as covered in Maintenance
Section.
3. Tighten all bolts and pins to the recommended
torque.
4. Check the cutter for worn or damaged parts.
Make replacements immediately.
5. Place driveline in storage position resting on
bracket.
6. Store the cutter in a clean, dry place with the
cutter housing resting on blocks.
7. Use spray touch-up enamel where necessary to
prevent rust and maintain the appearance of
the cutter.
PROPER TORQUE FOR FASTENERS
The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to
this chart to determine the grade of bolts and the proper torque except when specific torque values are
assigned in manual text.
RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL*
NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine
oil. They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants are
used. This applies to both UNF fine and UNC coarse threads.
