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.
