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. 

 
4.1  ENGINE ADJUSTMENTS & REPAIR 

Refer to the engine owner’s manual for those 
adjustments and/or repairs that can be made by the 
owner. 

 
4.2  MOWER DECK & COMPONENT ADJUSTMENTS 

The following mower deck and component 
adjustments and repairs can be made by the owner.  
However, if there is difficulty in achieving these 
adjustments and repairs, it is recommended that 
these repairs be made by an authorized SNAPPER 
dealer. 

 

WARNING 

Once blade is disengaged it should come to a stop in 3 
seconds or less. If the blade continues to rotate after 3 
seconds the blade brake must be adjusted. DO NOT 
continue to operate the machine if the blade brake is 
not operating properly. 

 
4.2.1.  BLADE BRAKE ADJUSTMENT 
The automatic Blade Brake should stop the blades 
within 3 seconds anytime the blades are 
disengaged by moving blade lever to the "OFF" 
position or by releasing the Blade Pedals. When 
the Blade Brake is properly adjusted there should 
be 1/8" to 1/4" clearance between the Blade 
Engagement Lever and the back of the Latch 
Plate. Check this by disengaging the Blade Lever 
and depressing the Blade Pedals as shown in 
Figure 4.2. If clearance is greater than 1/4" 
perform the following adjustment. 
1.  Remove Belt Cover. Refer to Section “BLADE 
BELT COVER REMOVAL”. 
2.  
With the blade engagement lever disengaged, 
hold the blade pedals down and measure the 
distance between the front of the blade lever and the 
rear of the latch plate.  The dimension should be 1/8” 
to 1/4” clearance between lever and plate.  See 
Figure 4.2.  If the dimension is incorrect go to step 3. 
3. If dimension is greater than 1/4”, rotate nut 
clockwise to increase brake tension.  If dimension 
is less than 1/8”, rotate nut counter-clockwise to 
decrease brake tension.  See Figure 4.1. 
4.  Reinstall belt cover. 

 
 
 
 

WARNING 

DO NOT operate machine until blade brake is 
adjusted and functioning properly. If blade stop time 
can not be achieved with the adjustment procedure 
described above, take machine immediately to an 
authorized Snapper dealer.
