SG18B Stump Grinder

Photos

Cat® Stump Grinders are designed to economically remove stumps in residential, commercial and agricultural settings. They offer increased production over tow-behind grinders in situations where multiple stump removal is required. The right balance of cutting wheel speed and torque makes quick work of most tree varieties.

Adjustability

Adjustable cutting wheel swing, extension and depth for superior operator control.

Hydraulic Controls

Swing and extension are controlled hydraulically from the operator's compartment using an electro-hydraulic valve for greater productivity and swing cycle time efficiency.

Dual Height Pivoting Stand Feet

Heavy-duty, dual height, pivoting stand feet provide a stable platform when grinding. Feet are adjustable to compensate for specific machine coupler-to-ground height and tire diameters.
