。 A horizontal control hydraulic cylinder 5 is provided between the lift arm 2 of the tractor 1 and the arm 3 connecting the work implement 21 to maintain the work implement 21 connected to the front or rear of the tractor 1 in a substantially horizontal position. In the interposed tractor 1, hydraulic oil is supplied to a hydraulic cylinder 24 for horizontal lateral movement, which is provided independently of the hydraulic cylinder 5, and is used to horizontally move the work implement 21 attached to the tractor 1. A hydraulic control device for a tractor, characterized in that a circuit is provided, and a switching mechanism 26 is provided to selectively send hydraulic oil to the horizontal control hydraulic cylinder 5 or the left/right lateral movement hydraulic cylinder 24.
