61" iCD Mower Deck
Install Deck Drive Belt
To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
1. See Figure 24. Remove the height adjustment pin
and lower deck.
2. Loosen the 5/16" bolts securing the mower deck
guards and remove the guards.
3. Belt is partially installed on the deck pulleys. Make
sure the V-side of the belt runs in the pulley grooves
(Figure 25).
4. Install the drive belt on the gearbox pulley, the
spindle pulleys and idler pulleys.
WARNING
Use extreme caution when rotating the idler
pulley with the wrench, due to the increased
tension in the spring as the idler pulley is being
rotated. Injury may result if the wrench is
prematurely released while the spring is under
tension.
5. Using a 3/4" combination wrench, rotate the spring-
loaded idler pulley (A, Figure 26) COUNTER-
CLOCKWISE and slide the drive belt over the edge
of the stationary idler pulley (C). Make sure the
V-side of the belt runs in the pulley grooves (Figure
25). Carefully release the tension on the wrench.
6. Reinstall the mower deck guards and tighten the
5/16" hardware to secure in place. Raise deck and
reinstall height adjustment pin (Figure 24) at desired
mowing height.
