PURPOSE:To maintain the chassis horizontal even on a slope, by providing a detector for detecting the inclination of chassis to the left and right and adjusting the rear wheel up and down in correspondence to the output from said detector to bring the chassis horizontal. CONSTITUTION:During planting work, inclination of the chassis 1 to the left and right is detected by a detector 35 and when the agricultural machine travels on an inclined field in the contour line direction, the output from the detector 35 will cause forward rotation of a motor 21 through a controller. Consequently the rotary shafts 24, 24 at the left and right of a speed reduction gear 22 are rotated in the clockwise and counter-clockwise directions respectively to rotate the left and right transmission cases 9 up and down through a line mechanism comprising an operating rod arm 25, rod 30, rolling arm 31, rod 32, etc. Consequently the left and right rear wheels 3 are adjusted up and down in the reverse direction to maintain the chassis horizontal. |
