If the Hub is removed from the Shaft for any reason, the Shaft and Hub should be coated with a heavy grease before reassembly to prevent Hub from freezing to Shaft.
Seasonal Slip Clutch Maintenance
It is important that the slip clutch slips when an obstacle or load heavier than the setting is encountered. Before using the cutter each season, use the following procedure to make sure the slip clutch will slip and give the overload protection required.
1.Loosen Bolts (8) until gap between adjusting nut (7) and guide ring is approximately 1/16”.
2.Attach machine to tractor, set engine at approximately half throttle and quickly engage PTO. This procedure will break slip clutch facings loose and allow the proper torque to be maintained.
3.Return the bolts to their original position as described above.
NOTE: If machine sits outside longer than 30 days and is exposed to rain and humid air, the clutches should be removed from machine and stored in a dry area. Slip Clutch facings will soak up moisture and cause the metal plates to rust badly. When this occurs, the
