Working in a paddy field a conventional tractor may sink deeply because of the very high moisture content and low bearing capacity of the soil. The tractive efficiency may be so low as to prevent the tractor from moving. In order to raise the tractive efficiency of a boat-type further, according to a point of view about reducing energy consumption by reducing the volume of the blade cavity, an idea of four-footed walking boat-type tractor is put forward, and a walking device with two feet and four small wheels is designed and manufactured. It can move on the rails of a paddy soil bin to simulate the tractive performance of a boat-type tractor in the paddy field. Kinematics and dynamics of the walking device is analysed. Because it can ensure that the blade foot enters and leaves the soil vertically, and eliminates the functions of the soil compression and pick by the blade entirely, so the volume of the blade cavity can be reduced to a minimum and the efficiency of the walking system has been raised considerably. Thus, it is feasible to adopt a four-footed walking mechanism in the boat-type tractor.
