360° Visibility

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

Seat Mounted Controls

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

Pressurized Cab

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

Hinged Radiator Grill

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

Tractor Platform

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

Long Life Mulching Head

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

Hydraulically Controlled

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

Closed Loop Hydrostatic Circuit

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

Reversible Drum

Easier operation and improved productivity.

Drum Speed Bar Indicator

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

Engine

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

Undercarriage

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.

Reversing Fan

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