BLADE CARRIER INSTALLATION
Clean the spines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and install flatwasher and 1" hex nut. Tighten nut holding blade carrier to minimum 450 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 450 ft. pounds. Install and spread cotter pin.
NOTE: After a few hours of operation always recheck blade carrier retaining nut torque.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from falling.
SLIP CLUTCH
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the driveline.
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. To adjust the slip clutch, tighten the spring bolts to
The slip clutch should be checked periodically and adjusted to compensate for wear. The lining plates are 1/8" thick when new. Replace after 1/16" 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.
