Overview

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.

Features

Application

Designed to economically remove stumps in residential, commercial and agricultural settings. Offers increased production over tow-behind grinders in situations where multiple stump removal is required.

Drive System

Direct drive system features a variable speed, unidirectional, gerotor style motor for optimal cutting wheel speed and high torque for efficient grinding performance.

Heavy Duty Cutting Wheel

Heavy-duty cutting wheel and 32 bolt-on and replaceable carbide teeth provide maximum durability and cutting efficiency.

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.
