AP-SC2560 & AP-SC2572 Skid Steer Rotary Cutter 326-836MK

Deck Leveling with

Optional Gauge Wheel

Refer to Figure 2-4:

WARNING

To avoid serious injury or death:
Always shut power machine down using the “Shutdown

Procedure” provided in this manual before servicing,

adjusting, cleaning, or maintaining the attachment.

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.

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.

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.

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.

IMPORTANT:

Do not over angle hitch plate forward.

Over angling can cause damage to deck and hitch.

Nominal Cutting Height

“A”

Gauge Wheel

Ratchet Jack

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.

39173

“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.
