Caterpillar has launched its new Cat D1 Mulcher, complete with its high-performance powertrain, closed-loop hydraulics and upgraded screening. The machine has been specially created to optimise performance when clearing a mix of small- to medium-diameter materials. Design-matched with the rugged Cat HM518 Mulcher, the D1 Mulcher clears a 188.2 cm (72 in) wide strip on each pass, making it the right machine for right-of-way construction and maintenance, site development, tree management and firebreak clearing.
The new mulcher is powered by the 77.6kW (104hp) Cat C3.6 diesel engine meeting 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 lower sloping hood line improves visibility to the mulching head, allowing the operator to better assess the jobsite from the cab. Standard auto reversing fan purges debris from the radiator and enclosures, plus the hinged grill requires no tools to access the radiator for cleaning.
Featuring cladding material in high-wear areas, the new HM518 Mulcher frame offers increased service life. To increase machine versatility, the new D1 Mulcher can be equipped with an optional variable-pitch/angle/tilt (VPAT) blade in XL, LGP or Intermediate configuration.
