Description

Technical field

[0001] The present invention relates to a work machine lifting device of a ground work vehicle, and more particularly to a work machine lifting device of a ground work vehicle that uses hydraulic pressure to lift the work machine. Background technique

[0002] The tractor, which is a ground work vehicle, can use an engine mounted on the front part of the vehicle body to rotationally drive the tilling claws of the work machine provided at the rear part of the vehicle body. The working machine is connected to the rear part of the vehicle body so as to be able to move up and down (up and down) by an upper link, a lower link, and the like. The working machine can realize the adjustment of the left and right inclination by the hydraulic cylinder for working machine tilt, and can realize the raising and lowering by the hydraulic cylinder for lifting of the working machine. That is, the two lower arms used to support the working machine on the lower side of the vehicle b...
