Available with either a conventional long undercarriage or a low-ground-pressure undercarriage, the new model works efficiently in soft underfoot conditions, on slopes, and in rough terrain. For added utility, the mulcher can be removed and an optional Cat VPAT blade installed.
The pressurized cab, with 360-degree visibility, is fitted with screens and "poly-carb" windows for added protection when mulching. The pressure gauge mounted to the mulcher frame allows the operator to easily monitor mulcher performance, and the hydraulically adjustable push guard and hydraulically operated front hood provide an added measure of safety. An air suspension seat, with seat-mounted controls reduces operator fatigue.
Caterpillar markets the D3K2 Mulcher as a complete model configuration, and the HM518 mulcher cannot be retrofitted to standard D3K2 dozer models. The new model does provide an added choice in combination with the Cat 299D XHP skid steer and 586S site-prep tractor.
