LEVELING MOWER AND ADJUSTING
PITCH
NOTE: To make measuring blade height easier, wrap a
wood block (approximately 1" x 5" or 2.5 cm x 12.7 cm)
with masking tape. With the end of the block on the
ground, mark the block with the mower blade. Measure
the distance from the end of the block to the mark.
1. Place mower in highest position.
2. Place anti-scalp rollers in highest position so they
do not touch the ground during adjustment.
3. Loosen upper nuts on hanger hooks.
4. Adjust height so blade is 4" (10.2cm) from ground
level. Turn lower nuts on hanger hooks clockwise
to lower rear of mower. Turn lower nuts
counterclockwise to raise rear of mower.
5. Adjust blade pitch so rear blade height is 1/8" to
1/4" (3 to 6mm) higher than front blade height.
Loosen flanged nuts and slide adjusting tabs up
or down to achieve proper pitch (Figure 8).
6. Tighten flanged nuts.
7. Tighten upper nuts on hanger hooks.
8. Reset anti-scalp rollers to match desired
attachment position.
