Caterpillar 140K Motor Grader SpecificationsCaterpillar 140K motor graders feature a Cat C7 six-cylinder engine that uses Caterpillar’s highly advanced ACERT™ combustion technology and produces up to 171 flywheel horsepower (FWHP).

Other notable features of the Caterpillar 140K motor grader include:

  • electronic throttle control, automated protection against downshifting when the grader is travelling too fast and variable horse power (VHP)
  • automated torque management and an Autoshift feature
  • direct drive powershift transmission with electronic control, with eight speeds in forward motion and six in reverse
  • a load-sensing, closed-centre hydraulic system
  • a frame designed for maximum strength and durability, and an optimally shaped moldboard with large throat clearance.
