Tips per Wheel 40

  • Impeller Clutch Torque Converter (ICTC) reduces wheel slippage and tip wear by modulating rim pull from 100 to 20 percent while depressing left pedal. After 20 percent rim pull is achieved the left pedal applies the brake.
  • Reduces wheel slippage without reducing hydraulic efficiency.
  • Improves fuel efficiency with its lock-up clutch torque converter providing direct drive.
  • Steering and Transmission Integrated Control System (STIC™) enhances operator comfort by integrating steering and transmission control functions in a single lever. Includes finger-controlled gear selection.
  • Low-effort integrated controls deliver faster cycles and help reduce operator fatigue.
  • The 836K's Steering System offers precise machine control enabled by its load-sensing hydraulic steering system.

  • High radiator air inlet with screen helps prevent trash from entering the radiator area, maintaining proper airflow and aiding debris to fall off.
  • Striker bars and optional cleaner fingers are located in front and behind the rear wheels and behind the front wheels. Striker bars help to keep wheels free of debris to assist the wheel tips in maintaining good compaction.
  • In cohesive material or severe packing conditions, optional cleaner fingers are available to further assist in keeping the wheel tips clean.
  • Roof extends past the cab doors and windows to minimize debris build up.
  • Suction fan allows ambient air to cool, enhancing cooling capacity. It also pressurizes the engine compartment, preventing trash build up.

  • More fuel efficient that previous model.
  • Engine Idle Shutdown can help you save fuel by avoiding unnecessary idling.
  • The 836K is built to be rebuilt, maximizing machine life, and minimizing environmental impact. Get the most from your investment, with our sustainable options including Cat Reman and Certified Rebuild programs.
