CHECKINGAND ADJUSTING REVERSEDRIVE BELTTENSION
Maintaining correct tension on the reversedrive belt is important to good performance and long belt life. A loose belt will slip on the engine andtransmis- sion pulleys and causethe tines and wheelsto slow down - or stop com- pletely - even though the engine is running at full speed. A loose belt can also result in premature belt wear.
If there is no reverseaction when the
ReverseClutch Control knob is pulled out, then the belt tension is too loose.
When checking belt tension, also check the belt for cracks, cuts or frayed edges and replace it as soon as possible.
