MAINTENANCE
WING SLIP CLUTCH (CAT IV)
There are two friction lining plates in this slip clutch. The correct adjustment procedure is to tighten M10 bolts
until spring is flat against pressure plate and there is no gap. Loosen each bolt two
revolutions for correct
settings. DO NOT
tighten bolts so that GAP noted in Mnt-R-0137 is less than 1/16".
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. There
are two types of clutches furnished. (1) A clutch with 8 coil springs and (2) A clutch with a single disc spring
with 6 adjusting nuts.
1. Loosen nuts (Figure Mnt-R-0150 & Mnt-R-0137) 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-0150 & Mnt-R-0137.
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 coil spring clutch to their original position as noted in previous
paragraphs.
