Section 3: Adjustments
Anti-Scalp Rollers
Refer to Figure 3-9:
The ZST40 mower has one anti-scalping roller (#3) and
the ZST48 mower has two anti-scalping rollers. Their
purpose is to minimize scalping of the ground when
mowing on rough uneven terrain. Their height should be
adjusted after setting the deck stop pin 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 And Leveling" on page 25.)
3. Remove 1/2" hex nylock jam nut(s) (#2).
4. Reposition anti-scalp roller(s) (#3) up or down in
mounting bracket (#1). See important note below.
IMPORTANT: The anti-scalp rollers will extend
below the deck bottom the distance shown below
when mounted in the following holes:
•
even with the deck bottom in the top hole.
•
1/2" below if mounted in the 2nd hole down.
•
1" below if mounted in the 3rd hole down.
•
1 1/2" below if mounted in the 4th hole down.
•
2" below if mounted in the bottom hole.
For protection of deck and blades, it is best if the
roller(s) are mounted in the lowest hole(s) possible
without rollers touching the ground.
For example:
If deck cutting height is set at 1 1/2", the rollers
should be mounted to the 3rd hole or 1" down from
the top hole.
5. Secure anti-scalp rollers to mounting bracket(s) (#1)
with 1/2"-13 hex nylock nut(s) (#2). Tighten nut(s) to
the correct torque.
