WARNING
!
To avoid serious injury or death:
Always shut power machine down following the “Shutdown
Procedure” provided in this manual before leaving the
1. Park skid steer with cutter on a level surface.
2. 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
than the front deck corner.
The Rotary Cutter should be operated with float chain
tight to hold front of cutter at the correct cutting height and
lift arms set to hold rear of cutter slightly higher off the
ground than the front.
IMPORTANT:
The front blade tip should be lower
than rear blade tip by approximately 1". The cutter is
subject to continuous material flow under the deck if
the rear blade is at the same height or lower than the
front blade causing horsepower loss, grass clumps,
blade wear, and frequent blade sharpening.
NOTE: Nominal Cutting Heigh
t 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.
As the skid steer travels over uneven terrain, the skid
steer hitch plate tilt angle and lift arm height will need
readjusting frequently to maintain correct deck
positioning.
Equipment Clearances
Visually inspect hydraulic hoses for possible pinch points
and length. Make any necessary adjustments before
putting equipment into service.
1. If necessary, have someone stand nearby that can
motion for the operator to stop if a problem develops
while checking for clearances.
2. With deck lowered to its minimum cutting height,
slowly retract hydraulic cylinders on end of loader
arms while watching for interferences between
between skid steer, skid steer wheels, and cutter.
Make sure hydraulic hoses are long enough and do
not become pinched through the full range of motion.
3. With hydraulic cylinders still retracted, slowly raise
cutter up while continuing to watch for interferences
between skid steer, skid steer wheels, and cutter
until height adjustment safety chain limit is reached.
4. Slowly extend hydraulic cylinders on end of loader
arms until front of deck is touching the ground.
5. Slowly lower deck down while retracting hydraulic
cylinders on end of loader arms until deck is level and
resting on the ground.
6. Be sure to make any necessary corrections to the
hydraulic hoses before putting cutter into service.

Nominal Cutting Height is the distance
from bottom of the front leading
cutting blade to ground level.
“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.
The rear deck corner should be raised
slightly higher above ground level than
the front deck corner.
