4.2  WHEEL DRIVE CONTROL ADJUSTMENT 
IMPORTANT: There should always be some slack in 
the wheel drive control cable when the wheel drive 
control is released. 

The Wheel Drive Control requires periodic 
adjustment to maintain proper belt tension on the 
transmission poly-v belt. Verify proper tension by 
checking the extension of the spring located at the 
end of the wheel drive control cable. 
1.  Stop engine and allow sufficient time to cool. 
2.  Engage wheel drive control. The length of the 
spring located at the end of the drive control cable 
should increase between ½” and ¾”. See Figure 4.4. 
If the spring does not increase between ½” and ¾”, 
adjustment is required. 
3.  To adjust the amount the spring extends (belt 
tension) slide the black spring cover up to expose 
the spring. Unhook the cable eyelet from the spring. 
4.  Grip the hook on the spring and turn either 
Clockwise or Counter-clockwise. Clockwise 
increases spring extension and belt tension 
Counter-clockwise decreases spring extension and 
belt tension. 
5.  Attach the control cable eyelet to the spring and 
recheck spring extension. If spring extension is 
correct slide the spring cover down over the spring. 
Start engine, and with blade control released (blade 
stopped) verify the wheel drive functions properly. If 
spring extension is not correct turn spring  
Clockwise / Counter-clockwise. 
6.  If drive problems persist after adjusting the spring 
extension Refer to Section “TROUBLESHOOTING” 
of this manual or contact your local Snapper Dealer 
for assistance. 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

 

 
 
 

 
4.3  DRIVEN DISC SERVICE

of clutch cable, worn belts, oily belts or broken 
springs. If the mower does not propel itself properly, 
check for the following problems: 
1.  Grease & oil on drive disc causing slippage. 
2.  Broken or disconnected drive spring. 
3.  Driven disc is out of adjustment. 
4.  Driven disc rubber ring is worn - does not contact 
drive disc properly. 
5.  Worn Poly-V Belt or engine drive belt. 
 

NOTE: If any of the above (1 thru 5) are causing 
problems, service as follows: 

 
4.3.1.  Cleaning Drive Disc & Driven Disc. 
If oil or grease on the drive disc or driven disc is 
causing slippage, clean 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.
