テイング制御装置。 A work implement 4 attached to the tractor 1 via a three-point linkage mechanism 12 is supported by a lift arm 3 of a hydraulic system 2 so as to be able to rise and fall freely, and when the work implement 4 is floating, the lift arm 3 is biased in the upward direction. In a floating control device equipped with a hydraulic cylinder 14 with an accumulator 16, the hydraulic cylinder 14 is a single-acting type, and a piston 18 and a piston rod 20 of this hydraulic cylinder 14 are connected.
A floating control device characterized in that a floating control device and a floating control device are separated so that they can freely come into contact with and separate from each other.
