The invention belongs to the technical field of operation machinery and provides a tractor hydraulic system and a tractor. The tractor hydraulic system comprises a hydraulic output unit, a lifting mechanism, a steering mechanism and a flow dividing unit, the lifting mechanism comprises a working pump and a lifting unit which are sequentially connected, the steering mechanism comprises a steering pump and a steering execution unit which are sequentially connected, and the flow dividing unit is used for partially dividing hydraulic oil output by the working pump and the steering pump. And the hydraulic pressure is transmitted to the hydraulic input end of the hydraulic output unit. According to the hydraulic system of the tractor, the flow dividing unit is arranged, so that the flow needed when the steering execution unit and the lifting unit work normally can be guaranteed, large-flow output of the hydraulic output unit can be achieved, and therefore the probability that one of an accessory, the steering execution unit and the lifting unit is out of control due to insufficient flow is effectively reduced; the operation stability of the tractor is improved.
本发明属于作业机械技术领域并提供一种拖拉机液压系统及拖拉机。拖拉机液压系统包括液压输出单元、提升机构、转向机构和分流单元,提升机构包括依次连接的工作泵和提升单元,转向机构包括依次连接的转向泵和转向执行单元,分流单元用于将工作泵和转向泵输出的液压油部分分流,并输向液压输出单元的液压输入端。本发明中的拖拉机液压系统通过设置分流单元,既能够保证转向执行单元和提升单元正常工作时所需的流量,又能够实现液压输出单元的大流量输出,从而有效降低属具、转向执行单元、提升单元的其中一者因流量不足而失控的概率,增加拖拉机作业的稳定性。
