Anti-Scalp Rollers
Refer to Figure 3-12:
The mower has four 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 stop pin to the preferred cutting height.
IMPORTANT: The anti-scalp rollers will extend
below deck bottom the distance shown below when
mounted in the following holes:
• Top hole: rollers are even with deck bottom.
• 2nd hole: rollers are 1/2" below deck bottom.
• 3rd hole: rollers are 1" below deck bottom.
• 4th hole: rollers are 1 1/2" below deck bottom.
• Bottom hole: rollers are 2" below deck bottom.
For protection of deck and blades, it is best if the anti-
scalp rollers are mounted in the lowest holes
possible without them touching the ground.
For example:
If deck cutting height is set 1 1/2" above ground, the
rollers should be mounted in the 3rd hole down or 1"
below the deck bottom.
