4.2MOWER 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 3” to 3-1/4" clearance between the Blade Engagement Lever and the edge of the Latch Plate. Check this by disengaging the Blade Lever as shown in Figure 4.1. Perform the following measurement and adjustment.

1.With the blade engagement lever disengaged, measure the distance between the front of the blade lever and the edge of the latch plate. The dimension should be 3” to 3-1/4" clearance between lever and edge of plate. See Figure 4.1. If the dimension is incorrect go to step 2.

2.Remove Belt Cover. Refer to Section “BLADE BELT COVER REMOVAL”.

3.If dimension is greater than 3-1/4”, rotate nut clockwise to increase brake tension. If dimension is less than 3”, rotate nut counter-clockwise to decrease brake tension. See Figure 4.2.

4.Reinstall belt cover and tighten bolts securely.

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.
