4.4. BELT SERVICE 

On self-propelled mowers, the engine belt transmits 
power from engine to 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 which would impair 
mower performance. The condition of the engine belt 
and poly-v belt should be checked after every 25 hours 
of mower operation. 
 
 
 
 

4.4.1.  Engine Drive Belt Replacement 
 

(Standard and Stretch Type Belts) 

1.  Empty the fuel tank. 
2. Standard Belt: Unhook the idler spring from the 
right rear wheel bracket. See Figures 4.18. 
2.A. Stretch Belt: Proceed to Step 3. There is no idler 
pulley on these models to disconnect. See Figure 
4.18A.
