4.4 HOW TO START AND STOP THE DISC MULCHER
FORESTRY DISC MULCHER CONTROLS
Your Forestry Disc Mulcher is designed to run o the skid steer loader’s auxiliary hydraulic system,
and is activated and deactivated by a control in the operator’s cab. The height and tilt functions of
your disc mulcher are operated with the control handles or pedals in the cab. Consult your skid steer
operator’s manual for instructions regarding these functions.
HYDRAULIC FLOW REQUIREMENTS
When operating the cutter, set the skid steer engine RPM to a speed that will produce the required
ow. Your skid steer dealer can measure the ow available on your machine and recommend a
throttle setting that is compatible with this attachment.
FDM44 = 20-30 GPM
FDM44 = 30-44 GPM
FDM60 = 32-44 GPM
FDM60 = 45-60 GPM
NOTICE
DO NOT exceed the designed ow rate (GPM) of your disc mulcher. Place a check mark in
the box next to your model for reference:
STARTING THE DISC MULCHER
WARNING
To avoid serious injury or death from thrown objects and ying debris, ensure no

NOTICE
Make sure the case drain hose is properly attached to the prime mover’s case drain connection. Warranty
may be void if attachment is ran without the case drain hose connected. Excessive hydraulic pressure
can blow out seals and damage the motor.
Verify that hydraulic hoses are securely locked to the skid steer hydraulic couplers before starting the
disc mulcher.
NOTICE
Before operating mulcher, check the hydraulic uid level in the skid steer and add oil if necessary.
WARNING
To avoid serious injury by hydraulic uid injection into your skin, never use your hand or
other body parts to locate a hydraulic leak. Detect leaks with a piece of wood or card board.

4.6 GENERAL OPERATING TIPS
LEARN
what the mulcher deck looks like in a level position when you are seated in the skid steer. Knowing
what a level mulcher deck looks like will prevent you from damaging the cutting teeth and disc by
mulching too close to the ground.
SLOW
the skid steer if the engine “bogs” down or if the disc speed is too slow because of too much load.
LISTEN AND FEEL
If you feel a strong vibration while cutting, slow the skid steer and see if the vibration stops. If not, stop
the mulcher, turn o the skid steer engine and investigate the cause. Refer to the “Troubleshooting
Chart” on page 32.
ALWAYS
be aware of your surroundings and pay attention to obstacles and terrain in front of you.
ADJUSTING MULCHER HEIGHT & LEVEL
Use the skid steer loader’s lift and tilt controls to adjust the height and level of the mulcher deck. Refer
to your skid steer operator’s manual for instructions on these controls.
WARNING
To prevent serious injury or death from ying debris, do not operate this mulcher if you
can see the cutting disc while seated in the operator’s seat. Lower the attachment before
continuing.
CAUTION
Use care when operating on uneven terrain or any type of sloped surface. Keep your cutter
low to the ground when working in these conditions to avoid a roll over that could result
in minor or serious Injury.

Ironcraftusa.com4.7 tree cut procedures 23Ironcraftusa.com4.7 tree cut procedures 22
4.7 TREE CUT PROCEDURES
HOW TO CUT TREES (NO MULCHING)
With the mulcher deck a few inches
above ground and in a level position
cut the tree using the left side of the
cutting head.
Slowly drive the skid loader forward
so that the right side of the mulching
disc cuts the tree.
Continue to push the tree away from the skid steer
with the push bar.
While cutting, continue driving
forward and tilt the mulcher back to
feed tree into top of mulching disc.
Tilt the front of the mulcher deck
down and back drag over remaining
branches to to rene the mulch.
For larger diameter trees make a notch cut on one side of the tree then drive skid loader to opposite
side of the tree to nish the cut and push the tree away from the skid loader.
CUT CAPACITIES
model material size tree size
FDM44 4" 8" DIA
FDM60 6" 14" DIA
When planning your cutting operation consider your mulcher’s cut capacity as shown in the chart below.
CAUTION
Always inspect work area before starting the cutter. Locate and mark any utilities, steel
posts, rocks or any other objects that could damage the mulcher during operation. Never
assume the work area is safe.

VERTICAL MULCH METHOD
CAUTION
Do not operate the mulcher with the skid loader arms fully raised on uneven or sloped
terrain as the skid loader may roll over resulting in serious injury.
Figure 4.7c - Vertical Mulch Method
4.8 TREE CUTTING TIPS
TIPS
1. Wait until the disc is up to speed before cutting to prevent material from jamming in the disc.
2. Slow down when mulching or cutting thick material to prevent machine from “bogging” down.
3. Allow the mulcher to come up to operating speed before making a cut.
4. Use the vertical mulch method when mulching trees larger than 6” in diameter.
REMOVING JAMMED MATERIAL
1. Switch o the auxiliary hydraulic circuit.
2. Place the outside edge of the mulching disc on a tree and rotate skid loader so the disc turns opposite
of its cutting direction allowing the jammed material to back out the feed side of the mulcher.
Raise the skid loader arms and tilt the
mulcher forward. Cut the top of the tree
on the left side of the cutting disc and push
the top of tree away from the skid loader.
Tilt the back at a 45 degree angle and
drop the mulcher onto the tree by low-
ering the skid loader arms.
