Benefits and Features

  • Features pivoting seat with integrated multifunction LCD display and control console
  • Outstanding visibility to the front and rear of machine
  • Low sound levels and vibration for greater operator comfort and productivity

  • The rear vision camera enhances visibility for more complete operator control and safety.

  • Built around the exclusive Cat dual pump propel system, two pumps provide separate dedicated flow to drum drive motor and rear axle motor for exceptional gradeability and traction in forward and reverse.
  • Electronic propel control provides more precise machine control.

  • Maintenance-free hitch bearings.
  • Extended maintenance intervals for vibratory system and hydraulic system, providing more uptime and lower maintenance costs.

  • More weight at the drum and greater amplitude.
  • Automated speed control and vibratory system functions make it easy to ensure consistent, high quality compaction.

  • Exclusive semi-autonomous Command for Compaction technology automates compaction to offer complete process control and help promote more uniform results.
  • Measurement and documentation technologies help the operator determine when compaction has been completed to specification for greater productivity and uniform compaction quality.
  • Accelerometer-based (CMV) and exclusive Machine Drive Power (MDP) measurement technologies available.
