PURPOSE:To conduct snow-removing work without colliding with a rivet, etc. on a road by mounting a box, to the edge section of the lower end of a rear opening section thereof an angle material is formed, to the rear section of the tractor in elevation-free shape and upward pointing the rear section of the supporting post of the box. CONSTITUTION:A box 30, a front section, left and right side sections and the bottom thereof are formed by metallic plates 31-34, is mounted to the rear section of the tractor through three-point links, etc. A plurality of the metallic posts 39 in the before and behind direction are set up under the bottom plate 34, and upward pointed toward the rear ends of the rear sections when viewing from the sides of the metallic posts 39, and the angle material 52 is mounted to the lower end section 44 of the rear opening section of the box 30. When the tractor is backed and snow is scraped, the edge section 45 does not collide with the rivet (a) even when the metallic rivet (a), etc. are projected to a road surface, and the edge section is not damaged because it is blunted by the angel steel 52. |
