4.4 BELT 

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 
1.  Empty the fuel tank. 
2.  Unhook the idler spring from the right rear wheel 
bracket. See Figures 4.16. 

 

 

 

IMPORTANT: DO NOT tip machine with carburetor or 
spark plug down. Oil from crankcase will saturate the air 
filter and cause the engine to be hard to start or not start 
at all. If contamination does occur, the air filter will have to 
be replaced. 

 
3. Remove the driven disc. Refer to Section 
“Replacing Driven Disc Rubber Ring” for driven disc 
removal procedure. 
4. Do not tilt mower with spark plug or carburetor 
down. Tilt mower up on its rear wheels and remove 
blade and blade hub. Assistance from another 
person may be necessary to hold mower in the 
tilted position.
