CHECKING AND ADJUSTING TENSION ON CLUTCH BELTS

Maintaining correct belt tension is impor- tant to good tilling performance and long belt life. A loose belt will slip on the engine andtransmission pulleysand causethe tines andwheels to slow down

-or stop - eventhough the engine is running at full speed. A loose belt will also result in premature belt wear.

While checking belt tension, also check for cracks, cuts or frayed edges. A belt in poor condition should be replaced.

Checking and Adjusting

ForwardClutchBelt Tension

It is important to maintain correct tension on the forward clutch belt. A loose belt will causethe tines andwheels to slow down - or stop completely - even though the engine is running at full speed.

A loose belt will also result in premature belt wear.

•Check belt tension after the first two hours of break-in operation and after every 10 operating hours.

•At the end of eachtilling season, check the belt for cracks, cuts or frayed edges. A belt in poor condition should be replaced.
