OPERATING INSTRUCTIONS

STUMP GRINDER


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.

5.

6.

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.

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.

Stop the grinder by de-activating the auxiliary hydraulics.

7.

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 & SERVICE


Regular maintenance is the key to long equipment life and safe operation. Maintenance requirements have been reduced to the absolute minimum. However, it is very important that these maintenance functions be performed as described below.

•

•

•

•

•

•

•

•

DAILY

Check all bolts and nuts for tightness.

Check mounting hardware on teeth and torque to min. 150 - max 180 ft. lbs.

Check teeth for damage, and replace as needed.

Check all safety guards and covers to make sure they are installed correctly.

Check for missing or illegible Safety Decals.

Replace any missing bolts or nuts with approved replacement parts.

Check hydraulic system for hydraulic oil leaks. See procedure below.

Visually inspect the machine for worn parts or cracked welds, and repair as necessary.

EVERY 40 HOURS

Lubricate all grease fittings.

(One on each flange bearing and one on center pivot.)

•

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 than 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.
