4.4.WHEEL DRIVE BELT SERVICE

On this machine, the engine belt transmits power from the engine to the drive disc. The drive disc powers the poly-v belt, which engages the transmission that powers the rear wheels. Should these belts become worn, they could cause slippage. The condition of the engine belt and poly-v belt should be checked after every 25 hours of mower operation.

4.4.1.Engine to Drive Disc Belt Replacement

1.Empty the fuel tank.

2.Unhook the idler spring and driven disc spring. See Figure 4.7.

3.Roll belt off of engine pulley

4.Remove belt from drive disc pulley groove and slide underneath driven disc

5.Reverse procedure to install new belt.

NOTE: The engine to drive disc belt does not require tension adjustment.

4.4.2.Transmission Poly-V Belt Tension Adjustment (Wheel Drive Control)

The transmission poly-v belt is tensioned by the spring on the end of the wheel drive control cable. Engaging the wheel drive control extends the spring applying tension to the belt, causing the drive to propel the mower. When engaged the spring should extend between ½” & ¾”. If extension falls out of this range adjustment is required. Refer to Section “WHEEL DRIVE CONTROL ADJUSTMENT” for the procedure.
