The present invention relates to a crop management device, which has been developed to allow movement without power while easily managing work at various heights in the process of managing and harvesting crops； Two first frames having a rectangular cross section extending in the front and rear direction and two second frames extending in the left and right directions are assembled to each other in the shape of a rectangular frame, the two are spaced apart from each other in the front and rear directions between the first frame A lower body composed of two first guide frames having a first guide groove extending in a longitudinal direction on an inner surface facing and fixed to extend in parallel； The chair is mounted on the upper surface of a rectangular plate shape, and one side of the circular ring is fixed to the top of the support rod and the support rod is vertically mounted on one side, and the basket or bag is inserted and fixed through the circular ring. An upper body on which a second guide frame having a second guide groove is mounted on outer surfaces in opposite directions with a narrower gap than the first guide frame； As long as the lower end is rotatably coupled to the rear end of the first guide frame and the upper end is formed with a first guide rod protruding to move into the second guide groove and a first roller mounted on the first guide rod. The pair of first lifting frames, the upper end is rotatably coupled to the rear end of the second guide frame and the lower end is mounted to the second guide rod and the second guide rod protruding to move into the first guide groove A pair of second lifting frames having a second roller formed thereon, first and second rotating shafts mounted on both sides intersecting with an 'X' so that the first and second lifting frames rotate with each other, and the second ends at both ends. A lifting block in which a first and a second rotation shaft are fixed and a fixing hole vertically penetrated at the cente
