HOC911 Self Propelled Swivel Head Stump Grinder

The HOC911 is a professional-grade self-propelled stump grinder powered by a Honda GX690 22.1 HP engine with electric start. Designed for demanding stump removal applications, it combines self-propulsion, a swivel grinding head, tungsten carbide cutting teeth, and a hydraulic walk system to provide precise and efficient operation across challenging terrain.

Powerful Honda GX690 Engine

The HOC911 is equipped with a Honda GX690 22.1 HP net engine and electric start for reliable power and convenient startup. Its high-torque engine provides the power required for demanding stump grinding operations while supporting the machine’s self-propelled movement.

Self-Propelled Hydraulic Walk System

The combination of a V-belt and hydraulic walk system provides smooth power transfer and controlled machine movement in both forward and reverse. The system is designed to make maneuvering easier across challenging jobsite conditions.

Swivel Head & ErgoSwivel™ Handle

The swivel head design allows the cutting head to move across the stump without requiring constant machine repositioning. The ErgoSwivel™ handle features 45-degree bidirectional adjustment, providing additional control when working around obstacles and in tight spaces.

High-Performance Grinding System

With a maximum blade disk speed of 2,200 RPM and a 12.6-inch (32 cm) blade disk, the HOC911 is built for efficient stump grinding. Its cutting system is designed to grind up to 18 inches above ground and approximately 9 inches below ground.

12 Tungsten Carbide Cutting Teeth

The grinder comes equipped with 12 tungsten carbide teeth arranged for effective cutting performance:

• 4 left-cutting teeth
• 4 right-cutting teeth
• 4 straight teeth

This configuration is designed to provide efficient cutting action while removing stumps from multiple angles.

Electromagnetic Power Clutch

The patented North American Electromagnetic Power Clutch provides controlled engagement and disengagement of the cutting system. It is designed for smooth operation while helping extend machine component life.
