This creation is related to an independent hydraulic power supply system for planters and harvesters. The independent hydraulic power supply system can be installed on the machine platform of the planter (harvester). It includes a hydraulic pump and a control valve. ； The hydraulic pump is connected with the control valve, the hydraulic pump provides hydraulic power, the output of the hydraulic oil is controlled by the control valve, and the output of the control valve is connected to the hydraulic drive of the planter (harvester) The device is used to provide the operating power required for the operation of the planter (harvester) without relying on the traction machine to provide power.本創作係有關一種播種機、採收機之獨立油壓動力供給系統，該獨立油壓動力供給系統可設置於播種機(採收機)之機台上，其包含有油壓泵及控制閥；該油壓泵與控制閥相連通，由油壓泵提供油壓動力，由控制閥控制液壓油之輸出動作，該控制閥之輸出端係連接至播種機(採收機)之油壓驅動裝置，藉以提供播種機(採收機)運作時所需之運轉動力，可不需再依賴曳引機提供動力者。
