MAINTENANCE
TIRES AND WHEELS
Before working on any tires and wheels make certain the Cutter is jacked up high enough and securely
supported. When installing laminated or airplane tires, be sure the flat side of the lug nut is against the Wheel.
When installing Sectional Tires and Wheels note the direction of travel and the curvature of rubber segments in
the tire (See Assembly Section). Do not exceed 15 M.P.H. on Sectional Tires. When removing Airplane Tires,
let all of the air out of the tire before removing lug nuts or wheel bolts or nuts. Remove valve core to make
certain that there is no air pressure left in tube before separating wheel halves to dismount tires. DO NOT
LOOSEN WHEEL CLAMP BOLTS BEFORE PRESSURE IS REMOVED FROM TUBE AND TIRE TO
PREVENT EXPLOSIVE SEPARATION OF WHEEL HALVES WITH POSSIBLE SERIOUS BODILY INJURY.
Maximum airplane tire inflation pressure is 50 PSI, minimum inflation pressure is 20 PSI. Inflate ribbed
implement tires to manufacturer rated PSI as shown on the tire sidewall.
SEASONAL TORQUE LIMITER 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/frozen
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 MntP-R-0018) on springs
until the springs can freely rotate, 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-
0018.
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 and tighten the nuts on the
springs to their original position of 1-9/16"
compressed spring length (top of washer to
pressure plate).
