Mower Belt Replacement - 36” Deck Models

NOTICE

To avoid damaging belts, DO NOT PRY BELTS OVER PULLEYS.

1.Park the tractor on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key.

2.Lower the mower deck to its lowest cutting position and remove the mower deck guards.

3.Using a 1/2” breaker bar, place the square end in the square hole located in the end of the idler arm (A, Figures 40). Carefully rotate the breaker bar CLOCKWISE, which will relieve the tension on the belt exerted from the idler arm.

WARNING

Use extreme caution when rotating the idler arm with the breaker bar, due to the increased tension in the spring as the idler arm is being rotated. Injury may result if the breaker bar is prematurely released while the spring is under tension.

4.Slide the drive belt over the edge of the stationary idler pulley (B). Carefully release the tension on the breaker bar.

5.Loosen the hardware that secures the stationary idler pulley and the chevron belt idler pulley (B & C) to the cutter deck and slide both pulleys forward towards the front of the deck. Remove the old chevron belt. Remove the old deck drive belt.

6.Install the deck drive belt on the PTO pulley, the spindle pulley and the adjustable idler pulley. Do not install the deck drive belt on the stationary idler pulley (B, Figure

41)at this time.
