GENERAL SAFETY PRECAUTIONS
WARNING! PROTECT AGAINST FLYING DEBRIS
Always wear proper safety glasses, goggles, or a face shield when driving pins in or
out, or when any operation causes dust, ying debris, or any other hazardous mate-
rial.
WARNING! LOWER OR SUPPORT RAISED EQUIPMENT
Do not work under raised booms without supporting them. Do not use support mate-
rial made of concrete blocks, logs, buckets, barrels, or any other material that could
suddenly collapse or shift positions. Make sure support material is solid, not de-
cayed, warped, twisted, or tapered. Lower booms to ground level or on blocks. Lower
booms and attachments to the ground before leaving the cab or operator’s station.
WARNING! USE CARE WITH HYDRAULIC FLUID PRESSURE
Hydraulic uid under pressure can penetrate the skin and cause serious injury or
death. Hydraulic leaks under pressure may not be visible. Before connecting or dis-
connecting hydraulic hoses, read your prime mover’s operator’s manual for detailed
instructions on connecting and disconnecting hydraulic hoses or ttings.
•Keep unprotected body parts, such as face, eyes, and arms as far away as
possible from a suspected leak. Flesh injected with hydraulic uid may develop
gangrene or other permanent disabilities.
• If injured by injected uid, 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 treat-
ment.
• Wear safety glasses, protective clothing, and use a piece of cardboard or wood
when searching for hydraulic leaks. DO NOT USE YOUR HANDS!

OPERATION
STUMP GRINDER
9773 7-29-14-2
INTENDED USE: This unit is designed for grinding stumps up to 12" (30.5 cm) high. Use in
any other way is considered contrary to the intended use.
GENERAL INFORMATION
The BRADCO stump grinder is perfect for landscaping and maintaining parks and mu-
nicipalities. The easy maneuverability of the skid steer allows access to areas often inacces-
sible and it is easily moved from site to site. The offset 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. Therefore the
time required to remove the stump grinder from the skid steer and attach a bucket for clean up
is greatly reduced from conventional stump grinders. Due to this arrangement, thorough knowl-
edge of the skid steer controls is necessary for machine operation. Read your skid steer opera-
tor's manual for information regarding skid steer operation before attempting to use the stump
grinder.
Follow all installation instructions 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 BE-
FORE OPERATING THE STUMP GRINDER.
OPERATE THE STUMP GRINDER FROM INSIDE THE OPERATOR'S STATION
OF YOUR SKID STEER LOADER ONLY.
1. Swing the stump grinder all the way to the right, align the grinder with the stump in such
a fashion that the skid steer is as level as possible from left to right.
2. Position the cutting wheel to the right of the stump. Lower the frame so the grouser pads
are resting on the ground. This will assist in stabilizing the unit for even cutting and re-
duce the inadvertent movement of the skid steer.
NOTE: It is recommended that the pivot pin, attaching the mounting bracket to the yoke,
be perpendicular to the ground or as close to perpendicular as possible for the best per-
formance of the unit.
NOTE: Be sure the cutting wheel is not contacting the ground.
3. Activate the auxiliary hydraulics to the stump grinder and increase the engine to full
RPM.
4. Adjust the cutting wheel to cut approximately 1 to 1-1/2" of stump.
75578
17

9774 7-29-14-2
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.
5. Swing the cutting wheel to the left across the top of the stump on the edge closest to
the skid steer. Lower the grinder another 1 to 1-1/2" and swing the cutting wheel back
across the stump to the right.
6. Continue cutting in this manner. If the wheel stalls, reduce the depth of the cut. Move
the skid steer as required to allow cutting a new area.
NOTE: Do not move into the stump while making a cross sweep. Machine and/or tooth
damage could result from motor overload.
NOTE: Make shallow cuts when cutting surface roots. Large chips can be broken off
and thrown if the cut is too deep.
