PROBLEM TO BE SOLVED: To carry out an arbitrary lifting and lowering operation, a forced lifting and lowering operation, a working state change operation and an automatically lifting and lowering operation while reducing a manufacturing cost and improving reliability. SOLUTION: This agricultural implement is equipped with a first electrically- driven actuator 43 for operating a switching valve 40 of a mechanical operation type for changing a flow state of a hydraulic oil to a hydraulic cylinder 2 for lifting and lowering an implement 4, a second electrically-driven actuator 43 for operating operation clutches 41 and 42 for intermitting a transmission to the implement 4 and a controller 39 for controlling operations of each electrically-driven actuator 43 based on detection information from detection means 32-35 and 37 for detecting operations of operation tools 31 and 36 of a driving part 14. A spool 40A of the switching valve 40 is mechanically connected to a ground body 15 so that the spool is located at a neutral position at a standard position of the ground body 15, at a rising position in a state of the ground body 15 positioning higher than the standard position and at a lowering position in a state of the ground body 15 positioning lower than the standard position.
