Driven and Drive Disc Service
If the mower does not propel itself properly, check for the
following problems:
1. Grease on the drive disc (A, Figure 23) causing slippage.
2. Broken or disconnected drive spring (B).
3. Driven disc (C) is out of adjustment.
4. Driven disc rubber is worn - does not contact drive disc
properly.
5. Worn Poly-V belt (D) or engine drive belt (E).
If any of the above (1 thru 5) are causing problems, service
as follows:
Cleaning Drive Disc & Driven Disc
If oil or grease on the drive disc or driven disc is causing
slippage, clean the discs as follows:
1. Wipe away any oil or grease with a clean cloth.
2. Use either an approved grease solvent or hot, soapy
water to clean drive disc or driven disc.
3. Rinse components with clean water.
4. Dry components with a clean cloth.
Drive Spring Repair/Replacement
If the drive spring (A, Figure 24) is loose, reconnect. If the
spring is broken, replace with a new spring.
Note: Use a pair of needle nose pliers to install the drive
spring.
IMPORTANT: If the drive system continues slipping, refer to
the Troubleshooting section.
Driven Disc Adjustment
If the drive disc and driven disc are clean and the mower
drive is still slipping, adjust the driven disc as follows:
1. Move the ground speed control (A, Figure 25) into the
‘fast’ position.
WARNING
DO NOT attempt any maintenance, adjustments or service
with engine and blade running. STOP engine and blade.
Disconnect spark plug wire and secure away from spark
plug. Engine and components are HOT. Avoid serious
burns, allow sufficient time for all components to cool.
