Supplemental Slip Clutch Instructions for the
RTH, RTN & RTNR Tillers
Bush Hog RTH, RTN and RTNR tillers may have either of two different types of slip clutches.
The drivelines equipped with Belleville spring plates require a more precise measurement
than the clutches equipped with external coil springs.
The compression of the Belleville spring many need to be adjusted if the clutch slips with the
original settings. Clutch slippage may occur from excessive tractor horsepower or ground
speed. If clutch slips, stop the tractor and tighten the adjusting nuts one flat at each of the
clutch bolts. Continue this process until the clutch stops slipping. Be sure to adjust the eight
nuts equally. Find the proper settings for your model in the chart below.
CAUTION:
Failure to compress the Belleville spring plate to the correct measure-
ment may cause damage to the implement and / or the tractor due to
improper slip clutch torque settings
