CUTTING HEIGHT ADJUSTMENT
The cutting height for vertical mowers can be adjusted
between 0-4 inches (0-102 mm). Actual cutting height
may vary somewhat from the heights given depending
on turf conditions and other factors.
Maintain air pressure in caster wheels at 22-24 psi
(152-165 kPa) to improve cutting height application.
Check air pressure when tires are cool. Inflate both
tires to the same pressure.
It is not necessary to remove cutting unit from tractor
when making adjustments.
Park the tractor on a flat, level surface. Raise the cut-
ting unit until the caster wheels are 3-4 inches (75-100
mm) off the ground. Stop engine and remove ignition
key. Place blocks under cutting unit so it is supported
on all sides.
Vertical mowers can be adjusted two different ways
depending on turf conditions and type of cut desired.
For normal operation, adjust both the push arm and
rear roller, along with the caster wheels – top portion of
Table 12E-1. This allows the height of cut to be
adjusted between 0-4 inches (0-100 mm) and lifts the
rear roller slightly off ground during operation. This
reduces wear to the rear roller and provides anti-scalp-
ing control.
To improve anti-scalping control or create striping
effects, remove adjusting pin from push arm and adjust
height using only rear roller and caster wheel – bottom
portion of Table 12E-1. This adjustment allows the rear
roller to ride over the ground surface and limits height
of cut from 0 to 2-1/2 inches (0-63 mm).
Figure 12E-5. Push Arm Adjustment (Right Side
Shown)
The push arm adjustment pins (Figure 12E-5) can be
inserted into one of nine holes. Use Table 12E-1 (col-
umn #2) for pin placement. The pins must be inserted
in the same hole on both sides of the mower.

WARNING
Never attempt to change height of cut with the
engine running. Serious personal injury can occur
from contact with moving parts.
NOTICE
When cutting undulated areas, lower cutting heights
may cause scalping. Adjust height accordingly to
prevent turf damage.
WARNING
To prevent serious injury, lower deck until it is resting
completely on the supports. This will prevent it from
accidentally lowering while making adjustments. Dis-
engage all drives, engage parking brake, stop
engine and remove ignition key.
NOTICE
With the rear roller adjusted down, roller bearing life
is reduced.
