Caterpillar D3K2 Dedicated Mulcher has a 72-inch-wide Drum

The Cat D3K2 Mulcher combines the foundation of the D3K2 dozer with the Cat HM518 mulcher to take on a mix of small-to-medium-diameter material in a wide range of applications, including right-of-way construction/maintenance, site development, tree management, and fire-break clearing.

Available with either a conventional long (XL) undercarriage or an LGP undercarriage, the new model works efficiently in soft underfoot conditions, on slopes, and in rough terrain, Cat says. For added utility, the mulcher can be removed and an optional Cat VPAT (variable-pitch/angle/tilt) blade installed. The width of the HM518 mulcher, featuring a 72-inch-wide drum, is matched to the operating width of the D3K2.

The pressurized cab is fitted with screens and "poly-carb" windows for added protection when mulching. The D3K2 Mulcher comes as a complete model configuration; the HM518 mulcher cannot be retrofitted to standard D3K2 dozer models.
