Main Characteristic


Advanced hydrostatic transmission with hydraulic mechanical drive. Wheel-motors in full time. High efficiency and splendid inching-function, excellent mobility and simple construction.

The design on principle “Human is the most important” make a good ergonomics-installation. Outstanding visibility of driver through its low profile of body. The cab can go up and down. Perfect signal and emergent system make operating safely and comfortably.

Main hydraulic components made by world-known companies such as Rexroth,MICO therefore have a high reliability and function-price ratio.

The hydraulic transmission system of this tractor is simple and clear, there are only a little rotate parts in the chassis. The layout of hydraulic pipes and electric cables are centralized and in good order.

Advanced four-wheel independent steering-by-wire technology. There are four reorientation models which make it pull round flexibly. No sideslip in the tyre.
