Easy To Operate
  • Cat Advance Ride Management (ARM) seat suspension reduces end stroke movement of the load cylinder for a smoother ride.
  • Engine overspeed protection will automatically engage with no operator input when the machine is in eighth gear. The machine will assist in slowing the machine speed by canceling the throttle command and engaging the engine compression brake.
Execute Efficiency
  • The Cat C18 tractor and C15 scraper engines meet U.S. EPA Tier 4 Final or EU Stage V emission standards, contributing to lower fuel consumption.
  • Using draft-arm overflow guards diverts material away from the bowl, preventing material from getting caught between the draft arms and the bowl sides.
  • The new tractor hydraulic demand fan helps lower fuel consumption.
