• Carefully study and understand this manual.
• Do not wear loose-fitting clothing, which may catch in moving parts.
• Always wear protective clothing and substantial shoes.
• Assure that all tires are inflated evenly.
• Give the unit a visual inspection for any loose bolts, worn parts or cracked welds, and make necessary
repairs. Follow the maintenance safety instructions included with this manual.
• Be sure that there are no tools lying on or in the equipment.
• Do not use the unit until you are sure that the area is clear, especially of children and animals.
• Don’t hurry the learning process or take the unit for granted. Ease into it and become familiar with your
new equipment.

Before Operation
Important Safety Information

9
TRBC Heavy Duty Brush Cutter
• Children should not be allowed on the machine.
• Clear the area of small children and bystanders before moving the machine.
• If using a towing unit, securely attach implement by using a hardened 3/4” pin, a metal retainer, and safety
chains if required. Shift towing unit to a lower gear before going down steep downgrades, thus using the
engine as a retarding force. Keep towing vehicle in gear at all times. Slow down for corners and rough
terrain.
• Make sure you are in compliance with all local and state regulations regarding transporting equipment on
public roads and highways. Lights and slow moving signs must be clean and visible by overtaking or
oncoming traffic when machine is transported.
• Beware of bystanders, particularly children! Always look around to make sure that it is safe to start the
engine of the towing vehicle or move the unit. This is particularly important with higher noise levels and
quiet cabs, as you may not hear people shouting.
• NO PASSENGERS ALLOWED! Do not carry passengers anywhere on, or in, the tractor or equipment,
except as required for operation.
• Keep hands and clothing clear of moving parts.
• Do not clean, lubricate or adjust your equipment while it is moving.
• When halting operation, even periodically, set the tractor or towing vehicle brakes, disengage the PTO,
shut off the engine and remove the ignition key.
• Be especially observant of the operating area and terrain. Watch for holes, rocks or hidden hazards. Always
inspect the area prior to operation.
• DO NOT operate near the edge of drop-offs or banks.
• DO NOT operate on steep slopes as overturns may result.
• Operate up and down (not across) intermediate slopes. Avoid sudden starts and stops.
• The brush cutter must be equipped with all protective guards (as provided by the manufacturer) against
access to moving parts. Guards must be complete and fully functional. Never operate the implement with
guards removed.
• When stepping on the brush cutter, be aware that the surface may be slippery. Place your feet only where
there are protrusions provided for this purpose, which are shown in the figure below.
During Operation
Important Safety Information

10
TRBC Heavy Duty Brush Cutter
• Your brush cutter discharges debris out the front of the machine. When cutting with the Brush Cutter,
NEVER discharge material toward bystanders. All bystanders must be AT LEAST 75 feet away when
operating the cutter. NEVER allow bystanders near the machine while in operation. When cutting near
bystanders is unavoidable, DO NOT operate the cutter without the front guard flap in place (if equipped
with guard flap).
• ALWAYS clear the cutting area of objects (bottles, rocks, fencing wire, etc.) that may be picked up and
thrown.
• ALWAYS use a shatterproof cab door or the 3/8” thick safety chain that came with your Brush Cutter
(optional) when cutting. The door is used not only to protect the operator from flying debris, but also from
overhanging or protruding objects (tree limbs, rebar, vines etc.) from entering the cab and operator injury.

Debris Discharge Warnings

TRBC Heavy Duty Brush Cutter
• ALWAYS disengage power to the Brush Cutter and shut the skid steer loader engine off prior to leaving
the operator's cab or performing any inspection or maintenance to either the brush cutter or the skid steer
loader.
• NEVER place hands or feet under the Brush Cutter deck or near the blade system while the unit is in
operation.
• NEVER articulate (roll) the deck downward to a degree that exposes the operator to the blade system.
• ALWAYS release the pressure on the hydraulic system of the cutter prior to removing the attachment from
the skid steer loader or working on any part of the hydraulic system. Hydraulic hoses and components
operate under extreme pressure and heat. A small stream of fluid from a pinhole leak in a hydraulic hose
can penetrate the skin and/or cause burns. Whenever hydraulic fluid is injected into the body, seek medical
attention at once to reduce chances of a dangerous infection. ALWAYS wash skin with soap and water
after contact with hydraulic fluid, as it is an irritant to skin and eyes.
• Your Brush Cutter has been designed to reduce the likelihood of hydraulic system leakage. Each and every
hydraulic system is checked prior to shipment. However, over time, any hydraulic system may develop
fluid leaks. Small leaks may produce high-pressure discharge flows capable of causing injury should skin
come in contact with such discharge.
• Leaking fluid can make the deck and ground surfaces very slippery, causing difficulty in using tools and
also increasing the possibility of slips and falls. ALWAYS wipe away all fluid that may have leaked during
maintenance.
• NEVER operate a Brush Cutter on a "high-flow" skid steer loader unless the cutter is equipped with a
"high-flow" motor. Motor failure can occur if such use is performed. Damage incurred to the hydraulic
motor due to "high - flow" usage is not covered. Please refer to the front cover of the manual for the
maximum allowable flow for your Brush Cutter.

Cutting Operation
The brush cutter is capable of, and in fact intended to be utilized for, mulching trees and other vegetation of
varying heights and diameters of up to 5” - 6”. As a safety feature, when cutting large diameter vegetation, the
Brush Cutter is equipped with a hydraulic motor cushion valve for shut down of the blade system. This feature
lessens the chance of damaging the cutter's hydraulic system or blade system when cutting larger diameter
vegetation. Directions for use are as follows:
Cutting Ground Level Vegetation
Raise the rear of the brush cutter approximately 4” - 5” above ground level. The deck of the brush cutter
should be sloping downward and away from the operator. This is the optimum position for cutting materials
that are close to the ground. Please note: If the operator can see the blade system in operation, the back of the
brush cutter is raised TOO HIGH!
Cutting Ground Level Vegetation
Raise the front deck of the brush cutter up approximately l’ - 2’ above ground level. Do not lift the rear portion
of the deck. Keep it approximately 4" -5" above ground level. Slowly drive into the vegetation and use the
hydraulic tilt (roll) to bend or push the vegetation over. As you bend the vegetation over and drive into it, the
blades will cut it into. The vegetation can now be mulched by rotating the front of the brush cutter and driving
forward several feet. Then roll the back of the cutter down and back-drag atop the vegetation.
