The D6R features a choice of an isolation-mounted, pressurized cab that reduces noise and vibration. Large, single pane windows offer good views all around the machine for maximum productivity and enhanced job site safety. The Comfort Series seat is offset by 15 degrees for better visibility. It features fully adjustable positioning and armrests to provide a comfortable platform when working on steep grades or slopes. Gauges and warning lights on the in-dash instrument cluster are easy to read, even in direct sunlight. The Cat Monitoring System Display gives operators and service technicians easy access to operating and maintenance information. The system provides three levels of warning and system monitoring so the operator can stay informed and still concentrate on the job. Heating and Air Conditioning vents evenly distribute airflow within the cab. The cab can also feature optional dual pane glass for extreme cold weather environments for further operator comfort.

Differential steering puts you on the leading edge of productivity by maintaining power to both tracks while turning. When one track speeds up, the other slows down an equal amount. Maneuverability - especially with large blade loads - is improved, as well as cycle times in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes because both tracks are powered during turns. A single tiller bar controls all directional and speed functions for ease of operation.

Standard Heavy Duty undercarriage components are designed for extended wear life in abrasive conditions and high impact applications like forestry, side-slopes, or working in rocky or uneven terrain. Heavy duty track is designed for enhanced penetration. The leading and trailing edges of each track shoe overlap the adjacent shoe to increase durability and component life.

L-shaped push arms bring the blade closer to the machine, providing excellent maneuverability, balance and blade penetration. The design provides solid lateral stability and better cylinder positions for constant pry-out independent of blade height.

The AccuGrade system automates blade control for improved grading accuracy and more cost effective operation. Sensors calculate precise blade slope and elevation, then automatically adjust the blade to maintain grade. Automated blade control improves efficiency by reaching grade faster and in fewer passes, reducing the need for traditional survey stakes or grade checkers.

The D6R features a monitoring system that provides feedback to operators with easy-to-read gauges and warning lamps that allows the operator to concentrate on the job at hand. With the use of a Cat Electronic Technician (ET), your Cat dealer can determine historical performance parameters of the machine. The Cat Monitoring System is designed to:
  • Reduce downtime
  • Match software to unique application needs
  • Provide feedback on machine performance events
