working order.
4
Always wear safety goggles or glasses when working on equipment.
5.
Use only manufacturer recommended replacement parts. Other parts may
be substandard in fit and quality.
WARNING! Escaping fluid under pressure can have sufficient force to penetrate
the skin, causing serious personal injury. Fluid escaping from a
very small hole can be almost invisible. Use a piece of cardboard or
wood, rather that hands to search for suspected leaks.
Keep unprotected body parts, such as face, eyes, and arms as far
away as possible from a suspected leak. Flesh injected with hydraulic fluid may develop gangrene or other permanent disabilities.
If injured by injected fluid, see a doctor at once. If your doctor is not
familiar with this type of injury, ask him to research it immediately to
determine proper treatment.

INSTALLATION INSTRUCTIONS
GENERAL INFORMATION
The following instructions will help you to mount your stump grinder onto
your skid-steer loader. The stump grinder uses the quick-attach system for ease
of installation. Therefore, if you know how to attach your bucket, attaching the
stump grinder should prove no problem.
Remember to read all safety warning, decals and operations instructions
before operating the attachment. If there is any portion of this manual that you do
not understand, contact your dealer.
IMPORTANT!
OPERATING THE STUMP GRINDER WITH THE INCORRECT MOTOR FOR YOUR SKID-STEER WILL GREATLY REDUCE THE
EFFICIENCY OF THE UNIT. MATCH THE HYDRAULIC FLOW (GPM) OF THE
SKID-STEER WITH THE HYDRAULIC FLOW (GPM) OF THE MOTOR IN THE
STUMP GRINDER DRIVE ASSEMBLY.
INSTALLATION INSTRUCTIONS
1.
2.
3.
Remove any shipping banding from around the stump grinder and skid.
Remove any attachment from the front of the loader.
Following all standard safety practices and the instructions for installing an
attachment on your skid-steer operator's manual, install the stump grinder
onto your skid-steer.
NOTE: IT IS IMPORTANT TO MAKE SURE THE LOCKING MECHANISM ON
YOUR QUICK ATTACH IS ENGAGED, THEREFORE LOCKING THE ATTACHMENT ONTO THE SKID-STEER.
4.
5.
Lower the unit to the ground and remove the key.
Relieve any pressure from the auxiliary hydraulic system and after making
sure that there is not any foreign matter on the hydraulic couplers, connect
the couplers to the auxiliary hydraulic system of your skid-steer loader.
DISCONNECT INSTRUCTIONS
1.
2.
3.
4.
5.
With the stump grinder extended out, lower the unit onto its side. NOTE:
Since the teeth will be exposed to bystanders, it is recommended to place
the unit towards the wall or in such a location to avoid inadvertant contact
with with the cutting wheel.
Following Safety Shut Down Procedures; stop the engine and set the
parking brake, relieve any pressure in the hydraulic lines.
Disconnect the power and return hoses from the auxiliary hydraulics.
Following all standard safety practices and the instructions for disconnecting an attachment in your skid-steer operator's manual, disconnect the

OPERATING INSTRUCTIONS
STUMP GRINDER
GENERAL INFORMATION
The BRADCO stump grinder is perfect for removing small stumps and
bushes. The easy maneuverability of the skid-steer allows access to areas often
inaccessible, and it is easily moved from site to site. The compact design offers
excellent visibility, and can be used in tight spaces around buildings and homes.
The quick attach mounting plate allows for easy hook-up and disconnect. Due
to this arrangement, thorough knowledge of the skid-steer controls is necessary for
machine operation. Read your skid-steer operator's manual for information regarding skid-steer operation before attempting to use the stump grinder.
Follow all installation instructions (Section F) for the proper installation of the
unit onto your skid-steer before operating.
STUMP GRINDING OPERATION
WARNING! CHECK THE WORK AREA AND KNOW WHERE ALL UTILITY
LINES ARE BEFORE OPERATING THE STUMP GRINDER.
1.
Set the speed selector on the skid-steer to slow, if so equipped. Start the
engine and position the grinder on the nearest side of the stump and to
the left.
2.
Lower the unit so you are grinding at a depth of 1/4" to 2".
NOTE: The cutting depth of each pass will be determined by the type of
tree. Certain varieties of trees will allow for a deeper cut than trees containing a lot of sap.
NOTE: It is recommended that the cutting wheel be perpendicular to the
stump or as close to perpendicular as possible for the best performance of
the unit.
3.
Activate the auxiliary hydraulics to the stump grinder and increase the
engine to full RPM. NOTE: It is recommended to always use full
throttle (maximum engine speed) when cutting with the stump
grinder.
4.
There are two methods of grinding, depending on the stump size and
operator preference. The skid-steer can be driven back and forth across
the stump, or the operator can swing the grinder using the skid-steer
controls. See Figure #1. NOTE: If you take too deep of a cut, the
grinder will stall. Raise slightly and try again. Continue grinding until
you have ground down a few inches.

GRINDING BY DRIVING THE
SKID-STEER BACK AND FORTH.
5.
Raise the loader arms to the original height, and move the grinder to the
right. Repeat steps #2 through #4 until you reach the right side of the
stump.
6.
Return the grinder to the left of the stump, lower and repeat steps #2
through #5 until you have ground the stump into the ground.
7.
Stop the grinder by de-activating the auxiliary hydraulics.
NOTE: It is recommended that the grinder be angled when grinding roots,
and that you grind along the length of the root by moving the skid-steer
over the root.
NOTE: Some operators prefer to operate the grinder at an angle for either
spoil placement or to increase productivity in tight spaces.

MAINTENANCE
STUMP GRINDERS
WARNING! Avoid serious injury. Lower the stump grinder to the ground, set
the parking brake, stop the skid-steer engine and remove the key
before leaving the operator's seat. If unit must be left raised for
maintenance block the unit securely to prevent accidental release
of the lifting mechanism. Disconnect the hydraulic couplers.
REPLACING TEETH
When replacing the teeth the unit must be placed on its side or blocked securely
off the ground to allow the wheel to rotate.
The teeth should be inspected regularly (every 8 hours) for tightness and to
ensure they are not worn or that the carbide tip is not missing or chipped. Tighten and
replace as necessary.
Replacing Square Teeth:
1.
With unit securely blocked off the ground and hydraulic couplers disconnected, remove lock nuts on teeth being replaced.
2.
Position new teeth and replace existing lock nut with new one provided.
3.
Torque to specification. (See Section "O".)
Replacing Bolt-On Teeth:
1.
With unit securely blocked off the ground and hydraulic couplers disconnected, remove the two sockethead capscrews securing the tooth to the
wheel.
2.
Position the new tooth on one side while retaining the existing tooth on the
other side and secure in place with the existing sockethead capscrews.
NOTE: Be sure to maintain the existing tooth pattern when replacing any
bolt-on teeth.
3.
Torque to specification. (See Section "O".)
REPLACING HYDRAULIC MOTOR
When replacing the hydraulic motor the unit should be either securely
blocked off the ground or attached to a hoist with the hydraulic couplers disconnected.
NOTE: Field replacement of the internal motor seals voids warranty.
1.
With unit securely positioned and the motor cover removed, disconnect the
hydraulic couplers and then tag and disconnect the hydraulic fittings and
hoses from the hydraulic motor. Note the hose routing for re-installation.
2.
Loosen the two sockethead capscrews on the collar. See Figure #1
