SITE INSPECTION
Before operating your brush cutter, carefully
inspect the area to be cleared. Remove any
items that may be picked up and thrown
by the cutting blades, such as wire, pipes,
rocks, etc. Mark objects that are too large
to move. This is an important step to avoid
personal injury, damage to property, the
brush cutter, or your skid steer. If an object
is struck while operating the brush cutter,
immediately shut down power to both the
brush cutter and the skid steer. Any damage
should be corrected and tested before the
continuation of cutting.
SKID STEER AUXILIARY
HYDRAULIC FLOW
Check the specifications of your brush
cutter’s rated gallons per minute (GPM) to
correctly match the hydraulic flow of your
skid steer to ensure proper operation.
FOR YOUR SAFETY, READ THESE INSTRUCTIONS.
The following safety instructions are provided to alert you to precautions that, if
not followed, may cause serious injury to yourself or to others. Please read these
instructions completely. Brush Wolf/Cross-Tech Manufacturing cannot cover every
incident that might be a hazard. Extreme caution should be used at all times. Only
use your Brush Wolf brush cutter for the purpose for which it has been designed.
EQUIPMENT INSPECTION
Disconnect the unit from the skid steer.
To inspect or to make repairs under the
cutter deck, always block the unit securely
to prevent accidental release of the lift
mechanism.
Inspect all hydraulic connections to ensure
they are tight, and hoses and shields are in
good condition before applying pressure.
Hydraulic fluid can escape under pressure
and may cause serious injury or death. If
this type of injury occurs, seek medical
attention immediately.
SAFETY GEAR
Wear safety goggles, hearing protection,
and a hard hat. Only operate the skid steer
behind a shatterproof forestry-rated door
and cab.
SAFETY FIRST!

BRUSH WOLF OPERATOR’S MANUAL | SAFETY FIRST!
DO NOT operate near bystanders, vehicles,
pets, livestock, or buildings. Objects may
discharge while cutting with the brush cutter
and has the potential to cause serious injury.
DO NOT operate the brush cutter until
everyone on your work crew is alerted to the
dangers of walking up to the brush cutter while
in operation.
DO NOT operate the brush cutter in conditions
with poor visibility.
DO NOT operate while intoxicated or if taking
medications that may impair your senses or
reactions.
DO NOT allow children to operate the
brush cutter. Only individuals with skid steer
experience who are well acquainted with the
rules of safe operation should be allowed to
operate the brush cutter.
DO NOT operate the skid steer without a
shatterproof forestry-rated door and cab.
DO NOT place hands, feet, or other objects
under the deck while the brush cutter is in
operation.
DO NOT raise the mower deck while blades
are rotating. Operation with the mower raised
will expose the cutting blades and may cause
serious injury or death to yourself or others.
DO NOT allow anyone or any item on top of the
mower deck while in operation.
DO NOT expose the underside of the blades
towards the cab while in operation.
DO NOT continue operation if an unexpected
object is struck. IMMEDIATELY shut down
power to both the brush cutter and the skid
steer. Disconnect the hydraulic couplers from
the power source. Evaluate the damage, repair,
and then test the unit before operation.
DO NOT leave the brush cutter unattended
while in a raised position. Always make sure
both the runners are placed firmly on the
ground and shut down the skid steer.
DO NOT attempt to straighten blades. Order
replacement blades if blades are bent, cracked,
or damaged.

Verify your skid steer’s hydraulic flow
to ensure it is within the brush cutter’s
rating range. The brush cutter’s gallons
per minute (GPM) rating is located on the
serial tag of the brush cutter.
OPERATING YOUR BRUSH CUTTER
CHECK BLADES
Inspect blades to ensure they are sharp,
tightened correctly, and intact. Look for
damage, dullness, and cracks. See page 9
for details.
CHECK HYDRAULIC FLUID
A low level could indicate a leak and require
a closer inspection of your unit. See page 9
for details.
CHECK NUTS & BOLTS
Tighten the 1) blade carrier to the gearbox,
2) blade bolts/nuts, and 3) hydraulic motor
mount nuts to torque specification listed on
page 10.
INSPECT THE DRIVE COMPONENTS
Remove any foreign material.

3) Inspect the hydraulic couplers and wipe off
water, dust, or any debris which can damage
hydraulic components. Once cleaned,
connect the couplers from the cutter to
the auxiliary hydraulic system on the skid
steer. If you have a HIGH FLOW skid steer
and brush cutter, attach the case drain to
the skid steer. Twist the collars of the quick
connect couplers to secure the hydraulic
connections. Do not operate the brush
cutter on high flow hydraulics (over 30 GPM)
unless the brush cutter is equipped with a
high flow motor as this may cause damage
to the motor and void the warranty.
4) Make sure the hoses are routed in a way
that allows the head to make a full range of
motion. If hoses are too long and pinching
or binding, they can be made shorter by
loosening the hose bracket and feeding
additional hose length back to the cutter
deck.
5) Confirm all safety measures have been
completed per the Safety First! section
(pages 2-3). Most importantly, make sure
the area is clear of people and pets.
1) Connect the brush cutter to your skid steer
with the universal Quick Tach Mount Plate.
2) Once connected, visually check the lock
pins to make sure the brush cutter is
securely locked into place. Raise the brush
cutter to 12” above ground level. Loop the
lift limit chain through the chain ring on your
skid steer and back to the chain bracket on
your brush cutter.
NOTE: All Brush Wolf brush cutters come
from the factory with the female flat faced
coupler on the pressure line and the male
coupler on the return line.

When done, lower lift arms, make sure the
cutter is placed flat on the ground, throttle
down on the skid steer, and shut off the
hydraulic flow to the brush cutter. Stop the
engine and engage the parking brake before
leaving the cab. Noise at shut down is normal.
DISCONNECTING HOSES:
To disconnect hoses, use proper hand
protection as the couplers may be hot. Always
replace caps on hoses once removed to
prevent contamination.
OPERATING STEPS
WHEN DONE CUTTING
1) Enter the shatter-proof cab door, engage
the seat belt, release the brake, and start
the engine. The runners of the brush
cutter should be as close to the ground
as possible. Never raise the brush cutter
more than seven (7) inches off the ground
while in operation.
2) Slowly apply hydraulics to the brush cutter
and increase the engine speed to high idle.
Make sure the unit is operating smoothly
before moving the skid steer forward.
3) Check for proper blade rotation. Blades
should spin COUNTERCLOCKWISE as
viewed from above (see Figure 3). If
rotation is reversed (clockwise), either
inverse the flow from your machine or switch
the QD couplers on the hose ends.
When temperatures are below zero, allow
additional time for hydraulic fluid to warm
up.
4) Maintain skid steer speed appropriate for
the volume of brush to prevent stalling.
5) Stay alert for drop-offs, rocks, holes,
abandoned wells, and septic tanks. Do not
operate or drive across a steep embankment
as this may cause a rollover and possible
injuries or death.
6) To cut large diameter brush and trees,
move forward slowly to make the cut.

Inspect blades before each use to ensure
they are sharp, tightened correctly, and
intact. Look for damage, dullness, and
cracks. Blades should rotate freely and be
clear of obstructions. Replace the entire set
of blades if damaged.
CAUTION: Always replace the entire set of
blades. Never weld or straighten damaged
blades, as loss of blade integrity may result.
CHECK HYDRAULIC HOSES AND HOSE
SAFETY SHIELD
Check for wear, damage, or leaks. Replace if
damaged.
INSPECT THE DRIVE COMPONENTS
Inspect before each use and remove foreign
material.

FIGURE 4: GEARBOX LUBRICATION
DIAGRAM
CHECK THE GEARBOX FOR PROPER
LUBRICANT
To check the lubricant level, remove the
pipe plug from the side of the gearbox. The
lubricant should be the same level as the
plug (see Figure 4). If low, add 85W-140
gear lube.
IMPORTANT: DO NOT overfill as too much
lubricant may rupture the gearbox seals.
