12" Cutting Wheel with 6 Carbide Teeth

The heart of the GUO110 is its 12-inch stump-grinding blade equipped with six carbide cutting teeth.

Carbide provides the durability needed for repeated contact with dense wood, while the rotating cutting assembly removes material a little at a time as the operator works the grinder across the stump.

The direct-drive configuration helps deliver engine power efficiently to the cutting wheel for consistent grinding performance.

Grind Stumps Below Ground Level

Rather than simply cutting a stump flush with the soil, the GUO110 is designed to grind material below ground level.

Published cutting capability includes:

• Up to approximately 10" above ground
• Up to approximately 12" below ground

Grinding below grade allows the remaining area to be backfilled after the job is finished, helping prepare the location for landscaping, grass, or other property improvements.

Compact & Maneuverable

At approximately 149.5 lbs., the GUO110 provides substantial cutting equipment while remaining compact enough for walk-behind operation.

The 10-inch rubber wheels help the operator reposition the machine around a property and maneuver it into areas that may be difficult to reach with larger stump-grinding equipment.

The SuperHandy GUO110 is well suited for:

• Residential stump removal
• Property maintenance
• Landscaping
• Tree removal cleanup
• Yard renovation
• Farm and ranch maintenance

Direct Belt-Drive Performance

The GUO110 uses a direct belt-drive system rather than relying on a slipping clutch to transfer cutting power.

This arrangement is designed to provide efficient power delivery from the engine to the cutting wheel, helping the carbide teeth maintain effective cutting performance as they work through the stump.

Important Operating Information

Stump grinding can throw wood chips, dirt, rocks, and other debris at high speed. Always wear appropriate:

• Eye protection
• Hearing protection
• Work gloves
• Protective footwear
• Long pants and suitable work clothing

Before grinding, inspect the area for rocks, metal, fencing, buried utilities, sprinkler lines, and other objects that could contact the cutting wheel.

Never operate the grinder near bystanders, children, or animals.
