The document describes the Titan Attachments Skid Steer Stump Grinder, model 120STMPGRNDRv2 (part number 124117), an attachment designed for skid steers to grind tree stumps.
Function Description
The Skid Steer Stump Grinder is an implement that connects to a skid steer to remove tree stumps. It operates by using a cutting wheel with specialized teeth to grind down the stump. The device requires an electrical power source for all functions to operate properly, connecting via a 14-pin connector or by removing the adapter to expose wiring for a direct 12V power source. Hydraulic hoses are also connected for power.

Usage Features
The stump grinder is designed for safe and efficient operation when attached to a skid steer. Key usage features and safety guidelines include:
- Operator's Manual: Thoroughly reading and understanding the manual is paramount for safe operation.
- Safety Labels: All instructions on safety labels must be read and followed.
- Trained Personnel: Only adequately trained individuals should operate the equipment.
- Operator Position: The implement must be operated from the driver's seat only.
- Guards and Shields: All guards and shields must be in place and secured before operation.
- Unattended Operation: Never leave the tractor or implement unattended with the engine running.
- Clearance: Maintain clear working areas and ensure all persons are clear when raising implements.
- Clothing: Wear snug-fitting clothing to avoid entanglement with moving parts.
- Power-Driven Parts: Keep hands, feet, and clothing away from power-driven parts.
- Transport Safety:
- Comply with state and local laws.
- Maximum transport speed is 20 mph; do not exceed.
- Reduce speed on rough terrain or when towing loads without brakes.
- Follow tow load weight ratios: 20 mph for loads less than or equal to tractor weight, 10 mph for loads double the tractor weight. Do not tow loads more than double the tractor weight.
- Rollover Prevention: Travel at slow speeds, avoid sharp turns and sudden movements on slopes, carry the stump grinder close to the ground, and avoid holes, ditches, and obstructions. Do not operate on excessively steep slopes.
- Riders: Never allow riders or passengers on the stump grinder, nor use it as a work platform.
- Power Lines & Utilities: Prevent electrocution by checking clearance before raising equipment and having local utilities mark underground lines before digging. Never leave the operator's seat if equipment contacts electric lines.
- Raised Attachment: Never enter the area under a raised stump grinder due to crushing hazards. Lower the stump grinder to the ground, engage the parking brake, shut off the engine, and remove the key before servicing.
- Operating Speed: Keep the stump grinder low and move at slow speeds on rough or uneven terrain.
- Attachment/Detachment:
- Attach/detach on a firm, level surface.
- Verify quick-attach pins are secure and fully engaged.
- Connect hydraulic hoses, ensuring they are clear of pinch areas. The case drain hose must be connected.
- Connect to a 12V power source.
- Test functions in a clear open area.
- Personal Protective Equipment: Always wear face or eye protection, safety shoes, and other appropriate protective equipment.
- Substance Use: Do not operate under the influence of alcohol, drugs, or if feeling ill.
- Bystanders: Keep bystanders away from equipment while in use and clear them before starting.
- Exiting Machine: Turn off the machine before exiting the operator station.
- High-Pressure Fluids: Relieve pressure before disconnecting hydraulic lines. Use paper or cardboard, not body parts, to check for leaks. Wear protective gloves and safety glasses. Seek immediate medical attention if fluid penetrates the skin.
Maintenance Features
Routine maintenance is crucial for the longevity and safe operation of the stump grinder.
- Cutting Teeth Replacement:
- Support the stump grinder to prevent falling.
- Stop the skid steer engine and remove the key.
- Inspect cutting teeth for damage. Rotate the tooth 3 times before replacing it.
- To replace, remove the lock nut (1) and cutting tooth (2).
- Install a replacement tooth and lock nut, tightening the lock nut (1) to 95 lb./ft. (129 Nm) of torque.
- Inspections:
- Hydraulic Hoses and Fittings: Check daily for leaks. Replace if worn or damaged.
- Contamination: Inspect the unit for any buildup of dirt, stones, etc.
- Cutting Teeth: Check every 2 hours of use. Keep cutting teeth in good condition; replacing broken teeth ensures faster cutting and extends the life of remaining teeth.
- General Maintenance:
- Work in a clean, dry area.
- Lower the implement to the ground, put the tractor in park, turn off the engine, and remove the key before maintenance.
- Allow the implement to cool completely before working on it.
- Do not grease or oil the implement while it is in operation.
- Inspect all parts for good condition and correct installation.
- Remove buildup of grease, oil, or debris.
- Remove all tools and unused parts from the implement before operation.
- Emergency Preparedness:
- Be prepared for a fire.
- Keep a first aid kit and fire extinguisher handy.
- Keep emergency numbers for medical and fire services near the phone.
- Hearing Protection: Wear suitable hearing protection (earmuffs or earplugs) to prevent hearing impairment from prolonged exposure to loud noise. Avoid wearing radio headphones while operating machinery.
