4.3.5.  BLADE BRAKE ADJUSTMENT 

The SNAPPER SCRAMBLER is equipped with an 
electric clutch/brake that should stop blade rotation 
in 5 seconds or less after being turned off. If blades 
continue to rotate longer than 5 seconds, 
adjustment or replacement is required. When 
properly adjusted, a .010” to .012” feeler gauge will 
fit thru the three inspection slots located on the side 
of the clutch as shown. See Figure 4.5. Excessive 
clearance can adversely affect the function of the 
clutch and produce blade stop times over 5 
seconds. To adjust, turn the three adjusting nuts 
clockwise to reduce clearance. The clearance at 
each of the three slots must be set the same.

WARNING 

Blades must stop rotating in 5 seconds or less after 
blades have been turned off. DO NOT operate 
machine until blade brake has been adjusted or 
repaired and is functioning properly. Contact your 
SNAPPER dealer for assistance. 

 

4.3.6.  CHECKING MOWER BLADE 
STRAIGHTNESS 

The straightness of the mower blade(s) is essential 
for smooth, even mowing. Check blade 
straightness as follows. 

NOTE:

 

Follow Steps 1 

thru 4 for all deck sizes. 
1.

 Close vent on fuel cap and make sure cap is 

tight.  Figure 2.2. 

2. 

Remove key from ignition switch. Engage 

parking brake. 

3.

 Remove spark plug wire(s) and secure away 

from spark plug(s). 

4.

 Raise cutting deck to highest setting.  With a 

floor jack, carefully raise front of machine to gain 
easier access to under deck.  Block machine 
securely.
