5.3PARKING BRAKE ADJUSTMENT

The parking brake can be adjusted to increase brake tension. (NOTE: If adjustment does not result in prop- er braking action, contact your authorized SNAPPER dealer for corrective action.)

1.Engage parking brake and measure height of left and right brake springs. See Figure 5.8. Compressed height of each spring should be 1-1/4". If not:

a.Disengage parking brake.

b.Tighten nyloc nut on each brake rod in one turn increments. See Figure 5.8.

c.Engage parking brake, recheck brake spring compression measurement, and repeat 'a' and 'b' as needed.

IMPORTANT - Do not adjust primary brake rod. Adjustment has been preset at the factory. See Figure 5.9.

8.Move deck lift lever and set the mower deck to the highest cutting position and recheck side to side blade tip dimensions. The difference between the two should be 1/8" or less.

NOTE: The deck timing rod is preset at the factory and requires no adjustments. See Figure 5.7.

9.The leveling blocks used in Step 4 should result in a proper deck pitch. If a pitch adjustment is required, use the two rear deck support eyebolts. Adjust up or down as required.
