To adapt to the environment of mountain orchard road transport characteristics, according to the tracked vehicle running characteristics, its general layout requirements were put forward based on the improvement of side rollover resistant capability of the tracked vehicle for mountain orchard. After the completion of all assembly designs, in order to improve side rollover resistant capability of the tracked vehicle for mountain orchards, the general layout of the system design was completed. The vehicle’s 3-D model was established and carried on the simulation. The simulation results showed that the design met the design requirements, and shortened the period of design.
