MAINTENANCE
BLADE CARRIER HUB INSTALLATION
Clean the spines on both the blade carrier and output shaft. position carrier on the gear box output shaft and
install flat washer and 1" hex nut. Tighten nut holding blade carrier to minimum 400 ft. pounds, strike the carrier
on the hub several times with a heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent
damage to the nut and threads. Retighten the nut to 400 ft. pounds. Install and spread cotter pin.
NOTE: Always recheck gear box output shaft slotted blade carrier retaining nut torque after a few hours
operation.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.
SKID SHOES
Wing skid shoes are replaceable and should be checked and replaced as required.
SLIP CLUTCH
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the
driveline. There are two types of clutches furnished. (1) A clutch with 6 coil springs and (2) A clutch with a
single disc spring with 6 adjusting nuts.
After the first hour of operation, the slip clutch should be checked for overheating. After this first check, the slip
clutch should be checked weekly or anytime there is overheating. (1)To adjust the coil spring slip clutch, tighten
the spring bolts 1/8 (maximum) turn at a time. Bolts should NEVER be adjusted to the point where the cpo;
springs are compressed solid. (2) To adjust the disc clutch, tighten the 6 bolts until they bottom out and then
loosen each of them 2 turns.
The slip clutch should be checked periodically and adjusted to compensate for wear. The lining plates are 1/8"
thick when new. Replace after 1/32" wear. If the mower has been idle for an extended period of time, or in wet
weather, before operating check to be sure the friction lining plates are not rusted/corroded together. Should
this occur refer to the procedure described in the "Seasonal Clutch Maintenance" section on the next page.
There are two friction lining plates in the slip clutch. These should be checked weekly for oil or grease, wear,
and moisture which could cause corrosion on the drive plates.
CENTER SLIP CLUTCH
There are four friction lining plates in this slip clutch. The spring length shown in Figure Mnt-R-0150 includes
the washer thickness. DO NOT adjust spring length (including washer) less than 1-15/32". Springs will become
solid and torque rating of clutch will increase drastically, which could cause a driveline failure.
