Bulldozer-skidder for skidding cut down trees model "STANISLAV" -704-04-BKU


PETERSBURG MACHINE BUILDING PLANT LLC is a manufacturer wheeled tractor equipment of 5-9 traction classes. Modern, the energy-rich tractor-bulldozer "STANISLAV" -704-04-BKU features high performance, economy, reliability, perfect design, comfort and serviceability. Bulldozer "STANISLAV" -704-04-BKU completed with additional mounted forestry equipment with jaw gripper (skidder for skidding cut down trees).

The tractor bulldozer has an improved frame structure with a balancer, located on a sub-motor bridge. By increasing the strength of the frame, on a tractor-bulldozer with additional mounted forestry equipment with a jaw grip (skidder for skidding cut trees) possible installation of an engine with a capacity of up to 600 horsepower. Among others advantages of "STANISLAV" -704-04-BKU:

  • imported axles with increased efficiency and a cross-axle differential lock function;
  • the use of a modern, specially designed manual transmission with hydromechanical gear shifting without interrupting the power flow for agricultural purposes;
  • as an option, it is possible to connect an additional hydrostatic transmission, which provides a smooth start-up and allows the tractor to move when working at a speed in the range from 0 km / h to 4.6 km / h;
  • updated cab design with roll cage and increased viewing angles;
  • improved components of the hydraulic system with a large resource and reliability;
  • a large selection of internal combustion engines with a capacity of 240 to 400 horsepower;
  • advanced gimbal.

The plant guarantees prompt delivery of the required amount of tractor machinery and equipment. All tractors are subject to the official guarantee.
