Cat® Stump Grinders

Caterpillar 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, wood structures and land clearing. The basic 2-over-3-tine construction and wide jaw opening also lends itself well to material handling. This includes sorting, loading, and, where possible compacting, of rock, scrap, pipe, waste material, and demolition debris.
