Ferris Industries 5900972, 5900645 Mower Belt Replacement, Troubleshooting, Adjustment & Repair

6.Manually position the left hand mower blade so that the tip of the blade is pointing towards the front and back of the mower. Measure from the front tip of the blade on the cutting edge to the ground. Record this distance. Measure from the back tip of the blade on the cutting edge to the ground. Record this distance.

Repeat this process for the right hand mower blade.

The front measurement should be 3” and the rear measurement should be 3-1/4”. If the measurements are correct, no further adjustment is necesary. If they are not correct continue with Step 7.

7.Loosen the jam nut (A, Figure 26) on the adjuster bolt (B) in the chain hanger clevis (C). Turn the adjuster bolt until the correct measurements are achieved. Ensure that all four hanger chains are taut, then retighten the jam nut against the chain hanger clevis.

MOWER BELT REPLACEMENT

To avoid damaging belts, DO NOT

PRY BELTS OVER PULLEYS.

PTO Clutch to Deck Belt

1.Park the machine 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.Remove the mower deck guard.

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.

3.Using a 1/2” breaker bar, place the square end in the square hole located on the end of the idler arm (A, Figure 27). Carefully rotate the breaker bar COUNTER-CLOCKWISE, which will relieve the tension on the belt exerted from the idler arm.
