ADJUSTMENTS
CHAINS
Tines may drop suddenly. Support the tines when
working underneath them. NOTE: It is normal for
there to be some play in the chain.
WHEEL AND TINE DRIVE CHAIN ADJUSTMENTS
1. Raise the machine and support it on the built in
jack stands. See jack stands section page 19.
Turn off the engine. This will allow one of the
sprockets to turn freely so the idler can take up
the slack.
2. Remove the side chain covers.
3. Tension by loosening the idler bolts and sliding
the idler in the adjusting slot to remove slack
from the drive. Tighten the idler bolts. Replace
chain covers.
NOTE: If there is no more adjustment, the chain
needs to be replaced. See Belt / Chain Replacement
Section
4. Start the engine and lower the machine. Stop
the engine and pin the jack stands in the operat-
ing position.
MAIN DRIVE CHAIN ADJUSTMENT
The main drive chain has an automatic tensioning
system that normally does not require adjustment.
As the chain wears, the tensioner advances and
locks the idler in the new position. If the automatic
tension has advanced all the way, it may be reset.
1. Raise the machine and support it on the built in
jack stands. Turn off the engine.
2. Remove the front and side chain covers.
Pull
the tensioner forward while lifting on the end
opposite of the spring to lock it in place.
3. Rotate the tire to get all the slack out of the top
span of the chain.
4. Loosen the idler bolts and move the idler in the
adjusting slot to remove the slack in the chain.
Tighten the idler bolts.
5. Move the tensioner off the locking notch to en-
gage the locking teeth.
6. Reinstall the chain covers. Start the engine and
lower the machine. Stop the engine and pin the
jack stands in the operating position.
