The blade switch engages the electric clutch when pulled out to the “ON” position. When the blade switch is in the “ON” position the cutting blade(s) are engaged. The blade switch disengages the electric clutch when the blade switch is pushed in to the “OFF” position. When the blade switch is in the “OFF” position the cutting blade(s) are disengaged. The electric clutch is non-adjustable. The blade(s) should stop rotation in 5 seconds or less. If the electric clutch fails to stop the blade(s) rotation in 5 seconds, contact an authorized SNAPPER dealer to repair or replace.

Blades must stop rotating in 5 seconds or less after blades have been turned off. DO NOT operate machine until blade brake has been repaired and functioning properly. Contact your SNAPPER dealer for assistance.

4.2.6.MOWER DECK ADJUSTMENT (LEVELNESS) Side-To-Side (48” Decks)

Before making deck leveling adjustments, check the tire pressure. Add or release air as needed to bring pressure to 12 P.S.I. in front and 12 P.S.I. in rear tires. If tires are properly inflated and mowing is still uneven, adjust side-to-side deck levelness first as follows:

1.	Place YARD CRUISER on a smooth level
surface.
2.	Remove floor pan.
3.	Rotate outside blades so tips are pointed to
the sides of deck. See Figure 4.4. Measure the
distance from blade tips to floor. If the
measurement is within 1/8” from side-to-side, the
deck levelness is satisfactory. If the difference
from side-to-side is greater than 1/8”, continue to
