SEM Track Type Tractor 822



Perfect for the transformation of rivers, lakes and landscape; and for the challenging demands of agriculture, irrigation, port and dam construction. Size selection is dependent on production requirements and project scale. This model is:

Efficient: Delivers outstanding levels of performance and maneuverability due to the hydrostatic drive system, that is controlled electronically, and the operational flexibility of a multi-functional joystick.

Productive: The ergonomic cabin section provides maximum comfort and visibility. The operator is kept fully aware of all vital functions by an advanced system that monitors machine operating conditions.

Reliable: Key features, such as the well-tested hydrostat design and world class pump and motors, contribute to a highly reliable machine. Hard-wearing undercarriage components provide longer life than its comparable leading competitor.

semi-universal blade

Semi-Universal (SU) blade

  • SU blade combines the excellent penetration of the S blade and the high production capacity of the U blade.
  • Designed for superior load retention and penetration in tightly packed materials.
  • L-shaped push arms bring the blade closer to the machine, providing excellent manoeuvrability, balance and blade penetration.
  • Blades feature a strong box-section design, made from high tensile strength steel to stand up to the most severe applications.
  • The undercarriage is provided by a world-class supplier ensures high reliability and resistance to wear.
  • Carrier rollers track rollers and idle rollers are all maintenance free.
  • Planetary final drive design delivers increased torque ratio for higher transmission efficiency and lower maintenance cost.
  • Durable final drive bearings and multiple wet disc brakes provide reliability, reduce system heat and extend overall life.
  • Machine structures are analyzed using Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) to identify and protect high-stress areas. Advanced structure welding technique, relieving welding stress.
