Benefits and Features

  • Advanced Productivity Electronic Control System (APECS) delivers improved transmission shifting performance and a higher level of comfort for operators.
  • Decelerator pedal acts as a brake, transmission neutralizer and an engine decelerator to override the engine speed selected by the throttle lock. Allows the operator to slow speeds when the throttle lock is engaged and to return to throttle lock without pressing a resume or set button.
  • Electro hydraulic controls increase productivity with responsive implements feature. Operate comfortably with easy-to-use soft-detent controls.
  • Steering System provides confident machine operation and precise control enabled by the 815K's load sensing hydraulic steering system.
  • Increased efficiency with variable displacement piston pumps that give operators precise positioning for easy maneuvering in tight areas with 42 degree articulation in each direction.
  • 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.

  • Designed and made with purpose-built structures to remain safe and durable for the long run.
  • Long-life-designs, materials and robotic welding ensure multiple life cycles and ability to withstand the toughest conditions.
  • Full box-section rear frame resists torsional shock and twisting forces.
