CUTTING HEIGHT _________________________________________________________

Cutting height for decks can be adjusted from 3/4 to 5-1/4
in. (19-133 mm) in 1/4 in. (6 mm) increments. Actual
cutting height may vary somewhat from the heights given
depending on turf conditions and other factors.
NOTICE
When cutting undulating areas, lower cutting heights
may cause scalping. Adjust height accordingly to
prevent turf damage.
1. Park the mower on a flat, level surface. Fully lower
cutting units. Stop engine and remove key from
ignition.
!
WARNING
To prevent serious injury, lower deck until it is resting
completely on the front casters and rear roller. This
will prevent it from accidentally lowering while making
adjustments. Disengage all drives, engage parking
brake, stop engine, and remove ignition key.
2. Refer to the chart provided for desired cutting
height.
!
CAUTION
Use proper lifting techniques when lifting or lowering
deck housings. The deck housing assemblies weigh
approximately 50 lbs (23 kg).

pins (A). Lift outer spindle shaft (B) slightly and
remove 1/2 in. (13 mm) spacers (D) and/or 1/4 in (6
mm) spacer (E) from bottom one at a time until
desired height is obtained. Carefully remove blocks
and lower deck housings (C). Place remaining
spacers on top of spindle and insert snap lock pins.
Washer (F) is always on top, under snap lock pin.
4. To raise height of cut, remove all three snap lock
pins (A). Carefully lift deck housing (C) above
desired cutting height and support with blocks. Add
1/2 in. (13 mm) spacers (D) and/or 1/4 in. (6 mm)
spacer (E) as required until desired height is
obtained. Lower deck housing. Place remaining
spacers on top of spindle and insert snap lock pins.
