From a family of machines with over 20 years of landfill experience, the 836K is powered with field-proven technologies to keep operations running at their peak.Cat Landfill Compactors are designed with durability built in, ensuring maximum availability through multiple life cycles. With optimized performance and simplified serviceability, our machines allow you to operate more efficiently and safely. Introduced in 1993, the 836 has been the industry leader for over 20 years. Focused on helping our customers succeed, we have continued to build upon each new series. The 836K continues our legacy of reliability, performance, safety, operator comfort, serviceability, and efficiency.

  • 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.

  • Cat Compaction Control system uses Machine Drive Power (MDP) technology to measure rolling resistance and correlates it with landfill compaction. 3D mapping indicates where to work and when layers are at optimum density. The system eliminates voids, optimizes cell space and documents results.
  • VisionLink 3D Project Monitoring provides managers with detailed compaction analysis to more effectively monitor and manage operations.
  • DETECT technologies help keep people and equipment safe by keeping operator aware of the work area and by monitoring and reporting unsafe conditions, like avoidance zones.
  • COMPACT technologies combine advanced compaction measurement, in-cab guidance and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and in fewer passes.
  • Rear vision camera greatly enhances visibility behind the machine to help the operator work with greater confidence and at peak potential while keeping people and assets safe.
  • Product Link is deeply integrated into your machine, giving you access to information like machine location, hours, fuel usage, idle time and event codes via the online VisionLink user interface. Helps effectively manage fleet and lower operating costs.

  • Railings, ladders and non-slip surfaces enhance technician and operator safety.
  • Rearview camera with in-cab monitor increases operator awareness around the machine.
  • Reduced vibrations to the operator with isolated cab mounts and seat mounted implement and steering controls.
  • Low interior sound levels.
  • Pressurized cab with filtered air.
  • Engine and power train guards prevent trash build-up and shield components.
  • Front frame guards prevent trash build-up inside the frame and protects components and hydraulic lines.
  • Axle wrapping and seal guarding prevents material from wrapping and binding around the axles and assists when cleaning is needed.
  • Transmission oil tube is guarded to resist damage from debris.
  • The fuel tank is positioned away from the debris in the front frame and is easily accessed.
  • 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.
