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 excavator/backhoe. If
an object is struck while operating the brush
cutter, immediately shut down power to both
the brush cutter and the excavator/backhoe.
Any damage should be corrected and tested
before the continuation of cutting.
EXCAVATOR/BACKHOE AUXILIARY
HYDRAULIC FLOW
Check the specifications of your brush
cutter’s rated gallons per minute (GPM)
to correctly match the hydraulic flow of
your excavator/backhoe 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 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 excavator/
backhoe. 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 excavator/
backhoe 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 excavator/backhoe
experience who are well acquainted with the
rules of safe operation should be allowed to
operate the brush cutter.
DO NOT operate the excavator/backhoe
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 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
excavator/backhoe. 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 excavator/backhoe.
DO NOT attempt to straighten blades. Order
replacement blades if blades are bent, cracked,
or damaged.

Verify your excavator’s/backhoe’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 8
for details.
CHECK HYDRAULIC FLUID
A low level could indicate a leak and require
a closer inspection of your unit. See page 8
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 9.
INSPECT THE DRIVE COMPONENTS
Remove any foreign material.

1) Ensure pins or quick couplers are properly
connected from the brush cutter to your
excavator/backhoe.
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.
2) 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 excavator/backhoe. If you have a HIGH
FLOW excavator/backhoe and brush cutter,
attach the case drain to the excavator/
backhoe. 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.
3) 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.
4) 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.

When done, lower lift arms, make sure the
cutter is placed flat on the ground, throttle
down on the excavator/backhoe, 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.
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 excavator/backhoe
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 excavator/backhoe 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.

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

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.
