Slope Indicate is included in the main machine display and shows side slope and uphill/downhill grades to help operators with slope work.AutoCarry automates blade lift to help you maintain consistent blade load and reduce track slip.*.

Traction Control automatically reduces track slip to save you time, fuel and track wear.*.Actively monitors machine load and track slip to help you reach optimal pushing capacity.* Blade Load Monitor gives you real-time feedback on current load versus the optimal blade load based on your ground conditions.Stable Blade works seamlessly with operator inputs to help produce a smoother surface when operating manually.Helps reduce operator fatigue by automatically maintaining straight travel with light loads or heavy loads on flat ground and side slopes. Steer Assist automates track and blade tilt steering.

For machines with 3D, operators can easily switch back and forth from full 3D automatics to Slope Assist.

Some blade and steering functions are automated so newer operators can work at productivity levels closer to their veteran counterparts. An air suspension seat (with seat-mounted controls) reduces operator fatigue and promotes high production.Ĭaterpillar markets the D3K2 Mulcher as a complete model configuration, and the HM518 mulcher cannot be retrofitted to standard D3K2 dozer models.Assist features help make work easier, especially for less experienced operators. 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.

The pressurized cab, with 360-degree visibility, is fitted with screens and "poly-carb" windows for added protection when mulching. Operator safety and comfort are priorities in the design of the D3K2 Mulcher. Finished debris size depends on the type of material being processed and the time allowed for multiple passes. The width of the HM518 mulcher, featuring a 72-in (1822 mm) wide drum, is matched to the operating width of the D3K2 for optimum efficiency and productivity. The reversing fan is beneficial as it reduces the time required to clean debris from the machine and ultimately optimizes machine uptime. The D3K2 Mulcher now comes standard with a reversing fan which automatically changes air flow direction periodically to purge debris from the radiator and enclosures. For added utility, the mulcher can be removed and an optional Cat VPAT (variable-pitch/angle/tilt) blade installed. Available with either a conventional long (XL) undercarriage or a low-ground-pressure (LGP) undercarriage, the machine works efficiently in soft underfoot conditions, on slopes, and in rough terrain.

The factory-built Cat ® D3K2 Mulcher combines the solid foundation of the D3K2 dozer with the ruggedly designed 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.
