Reduce stumps and surface roots with this gasoline‑powered grinder designed for ongoing property‑maintenance needs. The 420cc engine drives a carbide‑tooth cutting wheel that supports controlled grinding across the stump surface. A compact frame helps the machine operate in tight or restricted areas where larger equipment cannot reach.

The grinder’s structure suits property owners and small contractors who need a dependable tool for routine stump‑reduction tasks. Its layout supports steady operation during extended use.

Cutter Wheel and Teeth
Cutter Wheel and Teeth

Mounted on the 10-inch diameter cutter wheel are 8 sets of professional-grade teeth, enabling a cutting diameter of an impressive 12 inches . This allows for cutting stumps at a higher elevation from the ground. The pocket is forged from 42CrMo, and teeth are made of YG11C alloy, with a diameter of 1 inch. This design ensures more efficient stump cutting, improving work efficiency by approximately 35% compared to other types of teeth.

Chassis Rotation
Chassis Rotation

The design concept is to integrate the engine, cutter wheel, and handle into a single welded structure as a working unit. There is a set of rotating mechanisms between the working unit and the chassis. The lever on the right side of the handle can lock and release the chassis.

Left and Right Swing Rotation Angle
Left and Right Swing Rotation Angle

The chassis's left and right swing angle can reach 65 degrees, with a linear distance of up to 31.5 inches. This allows for easy cutting of stumps with a diameter of up to 31.5 inches, relying solely on the simple swinging of the chassis.

Tyre Fixation
Tyre Fixation

In our latest design, both tyres are fixed simultaneously, and the chassis swings left and right to perform tasks. The major advantage of this design is the ability to work more easily and continuously. Fixing both tyres at the same time ensures protection against collision injuries caused by operator errors, greatly improving operational safety.

Cutting Height and Depth
Cutting Height and Depth

With a maximum cutter wheel rotation diameter of 12 inches and a dual-wheel locking design, the handle can easily be pressed down, achieving a cutting height of 12 inches above the ground and a depth of 10 inches..

Adjustable Rotation Handle
Adjustable Rotation Handle

This lever controls the locking and releasing of the chassis. When the chassis needs to rotate during work, lift the lever. To move the machine to the next work area, return the lever to its original position, and simultaneously release the tire brake handle to enable movement.
