ABSTRACT:
Disclosed is a method of adjusting a tractor to a horizontal position and an apparatus for performing the same. The method comprises the steps of determining whether or not the tractor is in an automatic mode, determining whether the tractor is in a flat land or in a slope land if the tractor is in the automatic mode, adjusting a height of the body with respect to a ground if the tractor is in the flat land, determining a driving direction of the tractor if the tractor is in the slope land, adjusting the body to the horizontal position by controlling the body in left and right directions thereof if the tractor is driving in a contour direction, adjusting the body to the horizontal position by controlling the body in front and rear directions thereof if the tractor is driving in a latitudinal direction, and adjusting the body to the horizontal position by controlling the body in front, rear, left and right directions thereof if the tractor is driving in an oblique direction. The body of the tractor can be maintained to the horizontal position while the tractor is driving and the height of the body with respect to the ground can be adjusted, so the crops can be prevented from being damaged. The apparatus can rapidly adjust the body of the tractor to the horizontal position.
