SLIP CLUTCH
If a slip clutch is incorporated in the PTO driveline, it is designed to slip, absorb the shock load, and protect the driveline. This clutch has 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. To adjust the disc clutch, tighten the 6 bolts until Belleville Spring is flat 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.
All Safety Shields, Guards and Safety devices including (but not limited to) - the Deflectors, Chain Guards, Steel Guards, Gearbox Shields, PTO integral shields, and Retractable Door Shields should be used and maintained in good working condition. All safety devices should be inspected carefully at least daily for missing or broken components. Missing, broken, or worn items must be replaced at once to reduce the possibility of injury or death from thrown objects, entanglement, or blade contact.
