Benefits and Features

Easy viewing of the job site operating area PLUS a rearview camera.

Mounted on the air suspension seats, these controls isolate the machine vibration from the operator, reducing operator fatigue.

Heated and air conditioned cab offer comfortable working environment resulting in less operator fatigue and improved productivity.

Allows for easy clean out of radiator without the need for tools.

Balanced and rugged for operating in rough terrain and soft underfoot conditions.

New Cat® HM518 mulcher frame is designed for longer life using cladding material in high wear areas.

Mulcher conveniently operates with a hydraulically operated front door and adjustable push bar.

Delivers efficient, high performance power to the mulcher head, using less pump flow.

Easier operation and improved productivity.

In-cab indicator, aids operator in managing ground speed and overall mulching productivity.

Cat C4.4 diesel engine meets U.S. EPA Tier 4 Final/EU Stage IV emission standards.

Cat Sealed and Lubricated Track with 406 mm (16 in) or 635 mm (25 in) track shoes provides superior flotation and stability for wide range of operating conditions.

Auto reversing fan changes air flow direction to purge debris from radiator and enclosures.
