Overview

The Dosko Swivel Action Stump Grinder is engineered to make stump removal easier, smoother, and more comfortable for the operator. Featuring an innovative swiveling grinder head, this unit allows the cutting wheel to glide left and right across the stump with minimal effort. Simply position the grinder, engage the single-lever wheel lock, and let the swivel action do the work—reducing fatigue while improving control and efficiency.

Benefits:

  • Effortless grinding motion: Swivel action technology allows smooth left-to-right sweeping without constant repositioning.

  • Improved operator comfort: Reduced physical strain makes longer grinding sessions easier and more controlled.

  • Cleaner, safer operation: Side discharge design directs debris away from the operator and machine.

Features:

  • Swivel action grinder head: Designed for easy sweeping action across the stump for faster, more efficient grinding.

  • Honda GX engine: Reliable, long-lasting power trusted for professional stump grinding applications.

  • Single-lever wheel lock: Secures the unit in place during operation for added stability.

  • Direct belt drive: Efficient power transfer with durable, low-maintenance operation.

  • Cyclone air cleaner: Helps extend engine life in dusty jobsite conditions.

  • Oil shutdown sensor: Protects the engine by preventing operation with low oil levels.

  • 1.375-inch diameter bearings: Built for durability and smooth, consistent operation.

  • Side discharge frame: Keeps grindings away from the operator and improves visibility.

  • Five-position handlebar: Adjustable handlebar provides added comfort and control during operation.

  • Greenteeth® 3-in-1 tooth system: 700 Series teeth feature a concave “dish” cutting edge that shears rather than shreds; teeth rotate in three 120-degree increments for a fresh cutting edge in minutes.
