Deck Cutting Height Adjustment
Refer to Figure 3-11 on page 29:
Deck height is adjustable from 1” to 5” 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.
EXAMPLES:
•
When the height adjusting stop is placed in the 1” hole,
with the 1/4” plate facing to the front of the unit, the
cutting height is at 1”. When the height adjusting stop is
placed in the 1” hole, with the 1/4” plate on the
operator’s side of the hole, the cutting height is
at 1 1/4”.
•
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 1/4”, 1 3/4”, 2 1/4”, 2 3/4”, 3 1/4”, 3 3/4”, 4 1/4" or
4 3/4”.
•
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 1/2”, 2”, 2 1/2”, 3" 3 1/2" 4", 4 1/2" or 5".
The notch located at the rear of the right height adjusting
bar is used when the deck is placed in the transport
mode.

Anti-Scalp Rollers
Refer to Figure 3-15:
On the front of the mower deck are four anti-scalp
rollers (#6). Their purpose is to minimize scalping the
ground when mowing on rough uneven terrain. Their
height should be adjusted after setting the deck stop to
the preferred cutting height.
1.
Position mower and deck on a flat level surface.
2.
Set deck to the preferred mowing height. (Refer to
"Deck Cutting Height Adjustment" on this page.)
3.
Remove 1/2" hex nylock jam nuts (#4) from all four
anti-scalp rollers (#6).
4.
Reposition anti-scalp rollers up or down in the roller
mounting notches (A) with carriage bolts (#2 & #3) as
shown. See important note below.
5.
Secure anti-scalp rollers to the mounting brackets
with flat washers (#5) and 1/2"-13 hex nylock
nuts (#4). Tighten nuts to the correct torque.

IMPORTANT: The anti-scalp rollers will extend
below blade cutting height the distance shown below
when mounted in the following holes:
•
1/4" below if mounted in the top notches.
•
3/4" below if mounted in the 2nd notches.
•
1 1/4" below if mounted in the 3rd notches.
•
1 3/4” below if mounted in the bottom notches.
For protection of the deck and blades, it is best if the
rollers are mounted in the lowest possible notches
without the roller touching the ground.
For example:
If deck cutting height is set at 1", the rollers should be
mounted to the 2nd notches down from the top.
