Caterpillar reveals redesigned mulcher

According to Caterpillar, some of the D1 mulcher’s new features include a sloped hood styling for improved visibility; a high-performance powertrain; closed-loop hydraulics and upgraded screening.

Design-matched with the Cat HM518 Mulcher, the D1 clears a 188.2 cm wide strip on each pass, making it an ideal machine for right-of-way construction and maintenance, site development, tree management and firebreak clearing. 

The new mulcher is powered by the 104hp Cat C3.6 Diesel Engine that meets U.S. EPA Tier 4 Final/EU Stage V emission standards. An alternate emissions package for the C3.6 is available to meet Tier 3-equivalent standards.

The machine’s new sloped hood improves visibility to the mulching head, allowing the operator to better assess the jobsite from the cab. Cleaning and maintenance is simple, with a standard auto reversing fan purging debris from the radiator and enclosures; while the hinged grill requires no tools to access the radiator for cleaning purposes.

Inside the pressurised, heated and air-conditioned cab, the controls are mounted on the air-suspension seat to isolate machine vibration from the operator and reduce fatigue.

An intuitive operator interface features a 10-inch color touchscreen monitor with standard reversing camera display to further improve visibility of the operator’s surroundings. An in-cab drum indicator offers quick glance of drum speed and direction to help the operator manage ground speed and mulching productivity.

The HM518 Mulcher frame features cladding material in high-wear areas for increased service life, while bolt-on wear plates deliver long wear life and are quickly replaced. Offering a drum speed range of 2,150 to 2,450 rpm, the drum’s 38 fixed teeth feature a single-bolt carbide tooth retention design for simple replacement. The mulcher’s closed-loop hydraulic circuit includes load-sensing hydraulics to prevent rotor damage when hitting an obstruction. The HM518 Mulcher has a 78.7cm maximum lift height, 36.8cm maximum tilt and 25-degree maximum angle to either side.

Contractors can choose between the conventional (XL) or low-ground-pressure (LGP) undercarriage design, offering 40.4 cm or 63.5 cm track shoe widths respectively.

In addition, the new D1 Mulcher can be equipped with an optional variable-pitch/angle/tilt (VPAT) blade in XL, LGP or Intermediate configuration.
