  • A lower sloping hood line provides improved peripheral vision to the mulching head, allowing the operator to better assess the jobsite.
  • Mounted on the air suspension seats, these controls isolate the machine vibration from the operator, reducing operator fatigue.
  • Primary display is a 254 mm (10") touchscreen color monitor with back up camera.
  • Heated and air conditioned cab offers 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 C3.6 diesel engine meets U.S. EPA Tier 3 equivalent 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.
  • Improves engine air filter life by removing large debris particles.
  • The D1 features the lowest fuel consumption in this size class with the same great performance you've come to expect.
