①Horizontal: When the general wheeled farming unit is working, the right wheel of the tractor walks in the furrow. In order to make the first plough body connect with the previous stroke. To ensure that no missed tillage or re-tillage occurs, the distance from the end of the first plough body to the inner side of the rear wheel is generally 1~2cm. Crawler The right crawler of the tractor walks on the uncultivated land. In addition to ensuring the plough width, it is also necessary to prevent the crawler from collapsing the ditch wall.
The distance from the end of the first plough blade to the outside of the crawler is 10-20cm (this value is related to soil properties).
②Longitudinal: The longitudinal configuration of the plough should ensure that the rear wheel edge of the tractor does not prevent the first plough from turning over the soil when the unit is working. When the plough is raised or lowered or the ground is turning, the tractor shall not collide with the tractor. Under this premise, each part should be as close as possible to the tractor to improve the longitudinal stability of the unit and shorten the length of the ground.
