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
2.Attach cutter to tractor and start the tractor. Set the engine speed at 1200 RPM.
3.Mark outer plates as shown in Figure
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
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.
