DECK BELT REPLACEMENT
(Refer to Fig. 21)
Major causes of belt failure are improper in-
stallation and tension. Before installing a
new belt, check spindle shafts and bearings
for excessive endplay and wear by moving
each spindle shaft side to side and up and
down. Be sure they turn smoothly and freely.
Make sure idler is still aligned with spindle
sheaves.
Check sheave grooves for cleanli-
ness and wear. If grooves require cleaning,
use a cloth moistened with a nonfl ammable
nontoxic degreasing agent or commercial de-
tergent and water.
Avoid excessive force during installation. Do
not use tools to pry belt on or roll belt over
sheaves. This can cause hidden damage and
premature belt failure.
1. Position the mower deck in the lowest (1.5
inch) cut height setting and remove the left
and right belt shields.
2. Loosen the lock nut (A) and back off (coun-
terclockwise) the draw nut (B) until tension
is released from the old belt (C) and it can
be lifted off the deck sheaves.
3. Install the new belt following Fig. 21 for
proper belt routing.
4. Reset the belt tension using the procedure
in the “Deck Belt Adjustment” section.
5. Re-install the left and right belt shields.
