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.
the locator tab fits into the corresponding hole |
found on the idler arm. See Figure 4.4. Tighten bolt |
securely. |
6. Reinstall footrest/floor pan assembly. |
