Section 4 - ADJUSTMENTS & REPAIR 
 
WARNING 
DO NOT attempt any adjustments, maintenance, 
service or repairs with the engine running. Stop 
engine. Stop blade. Engage parking brake. Remove 
key. Remove spark plug wire from spark plug and 
secure away from plug. Engine and components are 
HOT. Avoid serious burns; allow all parts to cool 
before working on machine. Fuel Filler Cap and Vent 
must be closed securely to prevent fuel spillage. 
 
4.2.2.  MOWER DRIVE BELT ADJUSTMENT 
(FOR 25/28" DECKS ONLY) 
1.  Remove mower drive belt cover.  Refer to 
Section “CHECK MOWER DRIVE BELT”. 
2.  Move blade lever up and over to the “ON” position. 
3. Place deck cutting height in the 3rd position. 
Measure the belt spacing between idler pulley and 
belt. The distance should measure 1-1/4” but no 
less than 1”. See Figure 4.3. 
 
FIGURE 4.3 
 
4.  If the distance is less than 1”, adjust belt tension. 
5.  Move blade lever to the “OFF” position. 
6.  Loosen hardware that secures the clamp that 
anchors the front frame assembly to the rear main 
case. See Figure 4.4. 
7.  Pull front frame forward until belt spacing, with 
blade lever “ON”, measures 1-1/4”. 
8.  Retighten hardware that secures clamp. Make 
sure hardware is tightened securely. 
IMPORTANT: The SNAPPER Rear Engine Rider Models 
with 33” decks do not require belt tension adjustment. But, 
if front frame assembly clamp is loosened for any reason, 
recheck belt spacing between idler pulley and belt. With 
blade lever in the “ON” position, the distance should 
measure 1-3/4”. 
9.  When belt adjustment is complete it will be 
necessary to check Clutch/Brake Cable slack. 
10.  Disengage parking brake and allow pedal to 
remain in the engaged wheel drive (Up) position. See 
Figure 4.4A. 
11.  Clutch/Brake Cable should have approximately 
3/16” of slack. If the cable does not have slack 
adjustment of cable must be performed.

12.  Peel back the rubber clutch/brake pedal pad and 
push one ferrule through hole in pedal to attain slack 
in cable. See Figure 4.4A. Recheck cable for the 
approximate 3/16” of slack. Replace pedal pad when 
adjustment is complete. 
 
IMPORTANT: Too much slack may cause improper 
clutching and braking could be affected. Too little slack 
may cause improper clutch function. Recheck service 
brake/park brake and readjust if necessary. Refer to 
Section “SERVICE BRAKE/PARK BRAKE 
ADJUSTMENT”.
