The invention provides an agriculture machine control valve, and belongs to the technical field of hydraulics. The agriculture machine control valve solves the problem that the rising and falling movement of an existing agricultural machine execution mechanism and the steering movement of an agricultural machine are not convenient to control. The agriculture machine control valve comprises a valve body and a steering control valve cavity located in the valve body. A steering valve rod is arranged in the steering control valve cavity and slides along the steering control valve cavity so that a steering oil inlet can be selectively communicated with a left steering oil opening, a right steering oil opening and a steering oil return opening. The control valve further comprises a three-position four-way M type electromagnetic valve. An oil inlet and an oil outlet are formed in the valve body. An electromagnetic valve port A and an electromagnetic valve port B of the three-position four-way M type electromagnetic valve are connected with an execution mechanism to drive the execution mechanism to rise and fall. An electromagnetic valve port P of the three-position four-way M type electromagnetic valve is communicated with the oil inlet. An electromagnetic valve port T of the three-position four-way M type electromagnetic valve is connected with the steering oil inlet. A first oil inlet passageway and a second oil inlet passageway are connected through a throttling passageway. The steering control valve cavity is connected with an oil return opening through oil return passageways. By means of the agriculture machine control valve, the work efficiency of the agricultural machine under a complex geomorphological environment is improved.
