HM418 High Flow XHP Hydraulics Bite Limiter Mulcher

High-performance cutting and mulching of vegetation and overgrowth.



Use Mulchers for brush clearing, vegetation management, reclaiming untitled land, environmental maintenance, shredding pruned material and organic waste for biomass production.

High Performance Mulching

Designed for high-performance cutting, and mulching vegetation and undergrowth from typical wooded terrain. Reduces saplings, shrubs and trees into mulched material.

Rugged Mulching Head

Rugged mulching head processes trees up to 200 mm (8 in) diameter for effective land clearing applications.

Dual Speed Hydraulic Motor

Dual speed, axial piston motor provides smooth, efficient performance while delivering optimal torque under changing material loads.

Adjustable Push Frame

Standard adjustable push frame allows for control of trees for optimal cutting and efficiency. Low profile design improves operator visibility and pin-style segments provide the opportunity to control which section of teeth are cutting, improving tooth life.

Color-Coded Pressure Gauge

Color-coded pressure gauge is standard equipment that provides operator feedback in order to maximize productivity. With green, yellow, and red regions, the operator has indication of the load being applied to the mulcher and if adjustments can be made to maximize productivity in changing material loads.

Rear Chain Guard Protection

Rear chain guard protection reduces spread of material.

Serrated Steps

Serrated steps allow for safe and easy access in and out of the cab.

Lockable Service Panel
