Benefits & Features

Reliable Performance

    • Cut trees up to 152 mm (6 in) in diameter with the HM2615 and up to 305 mm (12 in) with the HM4015.
    • Two rotor types:
      • Standard – rotor with teeth only
      • Bite limiter – rotor with teeth separated by ribs to help prevent rotor stalling and creates finer shredded materials
    • Variable torque hydraulic piston motor shifts between high speed, low torque and low speed, high torque to give you speed when you need it and power when it counts.
    • Brackets allow the mulchers to be mounted on different excavators.
      • HM2615 – 11-16 ton tracked excavators, 13-17 ton wheeled excavators
      • HM4015 – 16-26 ton tracked excavators, 18-22 ton wheeled excavators
    • The staggered tooth design reduces stalling and jamming
    • Mulcher teeth options vary by application and preference on final material size:
      • Standard: Most commonly used option. Fairly fine final product used where there is minimal rock present and durability is needed.
      • Rock Crushing: Larger final product, but can work in applications where rocks are present.
      • Bite Limiter: Very fine final product due to aggressive edge of the blade with the limiters and counter knives. Use where rocks are minimal and there are large amounts of standing timber.
    • Hardened Counter Blades reduce finished material size and increase the rate of composting.

Easy Maintenance

    • Access internal components quickly and easily with bolt-on service panels.
    • Poly Chain Belt driven transmission eliminates slippage on startup, reducing maintenance costs.
    • The motor is integrated into the frame to protect it from dust, damage, and impact from falling debris.
    • Ensure service panel security with access bolts recessed into the panel, protecting them from debris.
    • Get back to work faster with field-replaceable wear parts

Prioritized Safety

    • Hydraulic Mulching door keeps the work environment and equipment safe by dispersing materials according to your application and surroundings.
    • The mulching door operation is controlled by electric diverter valve or medium pressure hydraulic kits from the cab.
      • Door closed – right of way clearing, near powerlines and pipelines, and roadside maintenance.
      • Door open – vegetation management, jobsite clearing, forest wood fuel removal, and firebreaks.
    • Flow control valve protects the motor from excessive flow
    • Ground level primary grease points keep you safe while performing daily maintenance
    • Bolt-on, replaceable skids keep the mulcher from going into the ground or into materials expediting wear or causing damage.
