The Hongwei-40 tractor equipped with a triangular half track walking device. This walking device is designed by the Guangdong Agricultural Machinery Research Institute and is specifically designed for use with the Hongwei-40 tractor. It passed the provincial scientific research appraisal in October 1979. With this device, the front wheels of the tractor are still retained, only the rear wheels are removed and replaced with this set of toothed straight triangular track plates. Therefore, it retains some of the performance of wheeled tractors while also having some of the characteristics of tracked tractors. It has the following advantages: 1. Due to good adhesion between the teeth and soil, it is not easy to slip and is not suitable for use
A half track tractor walking device has been developed to address the problems of poor climbing ability and low operating efficiency of wheeled tractors in hilly areas during field operations. The device mainly consists of walking brackets, deceleration mechanisms, track drive wheels, guide wheels, several support wheels, rubber belts, and tension wheel mechanisms. It has good adaptability to mountainous areas with certain slopes and is not easy to slip. Field driving performance tests have shown that the relative error between the front wheel linear velocity of the tractor and the linear velocity of the track drive wheels is controlled within, which meets the performance requirements of power machinery in field operations. The successful development of this track walking device is of great significance for promoting the development of agricultural mechanization in hilly and mountainous areas
