Setting the Sweeping Height
• Park on level ground.
• Start the machine and raise the deck
using the LH lever located on the
console.
• Secure the deck using the deck lift
safety locks.
• Adjust gauge wheel to desired height.
The deck height is set from the factory
in the middle hole of both the tube
and the rod. At this setting, a new
brush will contact the surface. To
adjust the brush to be more aggres-
sive, raise the gauge wheel to the next
set of holes that line up. To be less
aggressive, lower the gauge wheel to
the next set of holes that line up. The
adjustments are approximately ¼”
(.64 cm) increments. Set the gauge
wheel height the same on both sides.
• Check the sweeping height. Repeat
the steps in this section until desired
sweeping height is determined.
Adjusting the Anti-Scalp Rollers
• The anti-scalp rollers are set from
the factory so that the surface of the
roller is approximately 1” (2.5 cm)
below the front edge of the deck. To
adjust, remove the bolts and nuts
identified below and adjust up or down
accordingly. The rollers can be
adjusted in 3/8” (.95 cm) increments.
These are intended as anti-scalp
rollers only and not intended to roll on
the ground continuously.
