CHAIN REPLACEMENT
NOTE:
It is recommended replacement chains
from Schiller Grounds care, Inc. be used. Schiller
Grounds Care, Inc. supplies a premium quality chain
cut to the correct length. Replace all chains together
for best results under normal circumstances.
Tension on new chains will need to be adjusted after
the first several hours of operation after the chains
run in. See Chain Adjustment Section.
MAIN DRIVE CHAIN
1. Start the engine and raise the machine ion the
jack stands. Se jack stands section page 19.
Stop the engine. Open the transaxle by pass
valves so you can rotate the tines and axles
manually.
2. Remove the front, side and tine chain covers.
3. Push down on the spring end of the tensioner to
disengage the locking teeth. Pull the tensioner
forward and lock it in place by setting the bolt in
the locking notch.
NOTE: If replacing all chains, leave main chain
broken and lying in place while the wheel and tine
chains are replaced. It is easier to replace those
chains with the main chain broken because the
wheel and tine sprockets turn freely with the main
chain disconnected.
4. Break the chain by removing the connector link.
Inspect the sprockets. If any sprockets are worn,
remove the chain and replace sprockets before
installing the new chain. If the sprockets are still
in good condition, connect the new chain to the
old chain and use the old chain to pull the new
chain around the sprockets. Remove the old
chain and connect the ends of the new chain
with a new connector link. NOTE: Install all con-
nector links so the closed end is in the direction
of forward travel.
5. Push the idler up to take all the slack out of the
new chain and tighten the idler bolt. Make sure
the slack is out of the top span of the chain.
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.
TINE CHAIN
Tines may drop suddenly. Support tines when work-
ing underneath them.
1. Start the engine and raise the machine on
the jack stands. Stop the engine. Open the
transaxle by pass valves so you can rotate the
tines and axles manually.
2. Remove the front, side and tine chain covers.
3. Break the main chain and leave it lying on the
machine.

4. Loosen the idler mounting bolt and back off the
idler.
5. Break the chain by removing the connector link.
Inspect the sprockets. If any sprockets are worn,
remove the chain and replace sprockets. If the
sprockets are still in good condition, connect
the new chain to the old chain and use the old
chain to pull the new chain around the sprockets.
Remove the old chain and connect the ends of
the new chain with a new connector link. NOTE:
Install all connector links so the closed end is in
the direction of forward travel.
6. Take the slack out of the chain by moving the
idler in the adjusting slots. Tighten the idler
mounting bolt. Reinstall main chain.
7. Reinstall the chain covers. Start the engine and
lower the machine. Stop the engine and pin the
jack stands in the operating position.
