The invention relates to the technical field of agricultural machinery, and discloses a crawler tractor. The crawler tractor comprises a rear supporting shaft, a front supporting shaft, a power shaft,a gearbox, a diesel engine, front wheels and a tractor body, wherein the front end of the power shaft is fixedly connected with the rear end of the gearbox; the front end of the gearbox is fixedly connected with the diesel engine; and the diesel engine is fixedly mounted on the tractor body. Through arrangement of a crawler belt and rubber wheels, the tractor can be exchanged between a crawler belt mode and a wheel mode to perform multi-mode operation; through single crawler belt mode operation, enough pulling force can be effectively provided for the tractor to enable the tractor to operatein the field; through single-wheel mode operation, convenience is provided for remote transportation of the tractor, and transportation cost is reduced; through the crawler belt and wheel double modes, powerful dragging force is provided, and enough bearing force is achieved; thus, through exchanging of three modes, the pulling-out machine can be used in more occasions and adapt to different terrains, and the economical efficiency of the tractor is improved.
本发明涉及农业机械技术领域,且公开了一种履带拖拉机,包括后支撑轴、前支撑轴、动力轴、变速箱、柴油发动机、前置轮和机身,所述动力轴的前端与变速箱后端固定连接,所述变速箱的前端与柴油发动机固定连接,所述柴油发动机固定安装在机身上。通过履带和橡胶轮的设置,使得拖拉机在履带式与轮式进行调换,进行多模式运行,其中,单一履带模式作业,有效为拖拉机提供足够的拉力,使其在田间进行作业;单一轮式模式作业,为拖拉机的远程运输提供便捷,减少运输成本,履带、轮式双重模式,提供强有力的拖拽力,并且具有足够的承载力,三种模式之前的调换,使得脱拉机可以使用于更多的场合,适应不同地形,提高拖拉机的经济性。
