BLADE BRAKE ADJUSTMENT
(SINGLE BLADE DECK)
The BLADE BRAKE ASSEMBLY is designed to stop Blade
rotation within 3 seconds after the BLADE CONTROL
LEVER has been pushed downward to "OFF". Should the
Blades not stop within 3 seconds, the BLADE BRAKE must
be adjusted as follows:
1. Turn KEYSWITCH to "OFF".
2. Lower Deck to lowest position
3. Push BLADE CONTROL LEVER downward to "OFF"
position.
4. Inspect BRAKE BAND closely in order to determine
approximate amount of adjustment required.
5. Pull BLADE CONTROL LEVER upward to 'ON" position
(this loosens the brake assembly, allowing adjustment).
6. Tighten BRAKE BAND by loosening jam nut and turning
T-nut, on end of eyebolt, clockwise 1 to 2 turns, or until
brake band tightens. Make sure flanged lip on T-nut is
positioned vertically to fit over top edge of anchor. See
