WARNING
Engage parking brake, disengage power to cutter, shut off Skid
Steer, remove key and ensure that all moving parts have come
to a complete stop before dismounting from Skid Steer.
IMPORTANT: The blades should be positioned to
cut material only at the front of the cutter. If deck is
level or back of cutter is lower than the front, then the
blades are subject to continuous material flow
resulting in cutting clumps at the discharge chute,
horsepower loss, high blade wear, and frequent
blade sharpening.
NOTE: Nominal Cutting Height is the distance
from bottom of cutter blade to ground level at the
front of the cutter. Subtract 1 1/2" from Nominal
Cutting Height to determine distance (A). Distance
(A) is measured from bottom of front skid shoes to
ground level.
1.
Park Skid Steer with cutter on a level surface.
2.
Adjust ratchet jack to raise gauge wheel up until it is
even with bottom of front skid shoes.
3.
Use Skid Steer hydraulics to lower Skid Steer lift
arms and to tilt cutter hitch plate angle until bottom of
skid shoe at the front deck corner is dimension (A) off
the ground and the rear deck corner is slightly higher
off the ground than the front deck corner.
4.
Adjust ratchet jack to lower gauge wheel until it is at
ground level.
5.
With gauge wheel at ground level, use Skid Steer
hydraulics to adjust cutter hitch plate angle until the
float chain sags.
!
CAUTION
Do Not over angle hitch plate forward. Over angling can
cause damage to deck, hitch and gauge wheel.
The Rotary Cutter should be operated with gauge wheel
on the ground, slack in float chain, and deck rear slightly
higher off the ground than deck front. As the operator
travels over uneven terrain, the Skid Steer hitch plate tilt
angle and lift arm height may need some readjusting to
maintain correct deck positioning.

Cutter Hitch Plate
Ground Level
Nominal Cutting Height is the
distance from bottom of the
front leading cutting blade to
ground level.
The rear deck corner should be raised
slightly higher above ground level
than the front deck corner.
24585
“A” is 1 1/2" less than Nominal Cutting Height
and is the distance from bottom of Skid Shoe
at the front deck corner to ground level.
Float Chain should sag when gauge wheel is
resting on level ground. Adjust hitch plate
tilt angle to put a sag in the Float Chain.
