The following mower deck and component adjustments and

PER dealer.
Blade Brake Adjustment
The automatic Blade Brake should stop the blades within 3
seconds any time the blades are disengaged by moving the
blade lever to the “OFF” position or by releasing the Blade
Pedals. If the blades take longer than 3 seconds to stop,
perform the following measurement and adjustment.
1. With the blade engagement lever disengaged, measure
the distance between the front of the blade lever
(A,
Figure 32)
and the edge of the latch plate
(B)
. The
dimension
(C)
should be 3” to 3-1/4” clearance between
the lever and the edge of the plate. If the dimension is
incorrect go to step 2.
2. Remove the belt cover. Refer to the section entitled
“BLADE BELT COVER REMOVAL”.
3. If the dimension is greater than 3-1/4”, rotate the brake
adjustment nut
(A, Figure 33)
clockwise to increase
brake tension. If the dimension is less than 3”, rotate
the nut counter-clockwise to decrease brake tension.
4. Reinstall the belt cover and tighten the bolts securely.
