To solve the problem that a conventional tractor is configured so that an engagement hook provided at an auxiliary wheel side is moved along a shaft center direction of a tractor wheel to be engaged to and disengaged from an engagement beetle at the tractor wheel side, so that engagement of the engagement hook with the engagement beetle is loosened during work using the tractor.SOLUTION: A mounting fixture G for an auxiliary wheel of an auxiliary wheel for a farm tractor, which mounts an auxiliary wheel S on a tractor wheel 1, is constituted of an inner mounting fitting A having an engagement beetle 6 to be mounted on outside of a wheel 1 made of rubber of a farm tractor and an outer mounting fitting B that has an engagement hook 29 that engages with the engagement beetle 6 of the inner mounting fitting A and is detachably attached to the auxiliary wheel S made of metal. The engagement hook 29 is configured to be moved with a round handle 28 to the engagement beetle 6. The mounting fixture G for an auxiliary wheel is provided with an auxiliary wheel loosening prevention mechanism 35 that prevents the round handle 28 from rotating so as to prevent the engagement of the engagement hook 29 with the engagement beetle 6 from loosening.SELECTED DRAWING: Figure 3
【課題】従来、トラクターは補助車輪側に設けた係合フックをトラクター車輪の軸心方向に沿って移動させて、トラクター車輪側の係合杆に係合・離脱させる構成のため、トラクター作業中に係合フックと係合杆の係合が弛むという課題がある。【解決手段】農用トラクターのゴム製の車輪1の外側に取付けられる係合杆6を有する内側取付金具Aと、前記内側取付金具Aの係合杆6に係合する係合フック29を有し金属製の補助車輪Sに着脱自在に取付けられる外側取付金具Bとにより、トラクター車輪1に補助車輪Sを取付ける補助車輪用装着具Gを構成し、前記係合フック29は丸ハンドル28により係合杆6に対して移動する構成とし、前記補助車輪用装着具Gには前記丸ハンドル28が回転するのを防止することにより、係合フック29と係合杆6の係合が弛むのを防止する補助車輪緩み防止機構35を設けた農用トラクター用補助車輪の補助車輪用装着具。【選択図】 図3
