2006 CAT HM315

A lightly used CAT HM315 that spent most of its life in storage is hard to find. This hydraulic mulching head gives land-clearing crews a 57-inch cutting path without adding another dedicated machine to the fleet.

Who This Machine Is For

• Land-clearing contractors — clear brush, shrubs, saplings, and small trees with a compatible carrier.
• Forestry crews — maintain trails, right-of-ways, fire lanes, and wooded properties.
• Utility contractors — control vegetation around access roads and utility corridors.
• Property owners — reclaim overgrown acreage using a skid steer or compact track loader.
• Operators comparing mulching equipment — our forestry mulcher guide explains where these heads fit.

What It Grinds

• Brush and undergrowth — reduces dense vegetation into ground-level mulch.
• Saplings — the fixed-tooth rotor cuts and processes young trees.
• Small trees — CAT rates the HM315 for material up to 8 inches in diameter.
• Pruned wood and organic debris — processes suitable material for cleanup or biomass applications.

This is a forestry mulching head, not a wood chipper or production grinder. Its capacity depends on the carrier, hydraulic output, tooth condition, material, and terrain.

Specs in Plain Language

The HM315 has no engine; its axial-piston motor needs approximately 31.5–36 GPM at 2,828–5,075 PSI, so buyers must confirm carrier compatibility. Its 57-inch working width covers nearly five feet per pass, while the 72-inch overall width matters for transport and access. The V-belt-driven rotor carries 34 fixed teeth and operates at 1,800–2,100 RPM. Buyers maintaining other size-reduction equipment can also review our grinder tips and hammers.
