LKT 81 ITL

The concept of the LKT 81 ITL forest wheel tractor retains the tried-and-tested classic layout of the LKT 81 T with all-wheel drive of the same size and a pivoting frame.

Skidder is steered by articulation of the frames by two hydraulic cylinders. Articulation of frames around the vertical pin is possible up to 43 °. Such designed chassis, in connection with a 93 kW engine unit, a hydrodynamic transmission with under-load shifting, a mechanical single-stage transfer case and the possibility of blocking the hydrodynamic converter, allows excellent manoeuvrability and driving even in very demanding terrain.

LKT 81 ITL is designed for pulling the logs from the stand by the method of collecting rope. It has an ideally dimensioned double-drum winch with a pulling force of 80 kN.

After pulling the logs to the tractor, they are transported by towing in a semi-trailer.

The front blade is specially designed for ramping logs and can also be used for simple earthworks

  • Safety cab with modern design provides the operator with greater comfort, allows an ideal view outside and better material handling
  • Two hydraulic articulation cylinders extend the service life, improve the stability of the machine and its strength
  • Gearbox with hydrodynamic converter provides precise and comfortable shifting under load (without clutch and stopping)
  • Optional remote control for driving and steering simplifies the operation of the tractor and increases safety at work
