4.4 MOWER BLADE BRAKE ADJUSTMENT

WARNING

The following procedure requires the engine and
blades to be operated. Exercise extreme caution. Clear
area of loose parts & tools first. Only operate blades
when seated in the operator’s seat.

The blade brake when properly adjusted will stop
blade rotation in 3 seconds or less when the blade
control lever is moved to the “OFF” position.
Blade brake adjustment is made by turning the
adjustment nut on the threaded brake rod. The
brake is initially set with 7/16” of thread exposed
beyond the nut. See Figure 4.9. Verify this setting
before attempting any adjustments.
To tighten the brake (stop blade rotation quicker)
turn the adjustment nut clockwise - ONE TURN
ONLY.

IMPORTANT: DO NOT over-tighten blade brake.
Tighten one turn and check function of brake. If
blade stop time remains over 3 seconds, turn
adjustment nut one more turn clockwise. If blade
stop time remains over 3 seconds DO NOT
OPERATE machine. Contact your local SNAPPER
Dealer for assistance.
