Deck Cutting Height Adjustment
Deck height is adjustable from 1 1/2” to 4 1/2” in 1/4”
increments. The holes in the height adjusting bar are
spaced at 1/2” intervals. By turning the height adjusting
stop around, 1/4” increments can be attained due to the
1/4” plate that is part of the stop. Refer to Figure 3-8.
EXAMPLE: When the height adjusting stop is placed in
the 1 1/2” hole, with the 1/4” plate facing to the front of the
unit, the cutting height is at 1 1/2”. When the height
adjusting stop is placed in the 1 1/2” hole, with the 1/4”
plate on the operator’s side of the hole, the cutting
height is at 1 3/4”.
When the height adjusting stop is placed in one of the
holes, with the 1/4” plate on the operator’s side of the hole,
the deck height will be set at one of the following: 1 3/4”,
2 1/4”, 2 3/4”, 3 1/4”, 3 3/4” or 4 1/4”.
When the height adjusting stop is placed in one of the
holes, with the 1/4” plate facing to the front of the unit, the
deck height will be set at one of the following: 1 1/2”, 2”,
