PROBLEM TO BE SOLVED: To provide a leveling plate-supportingdevice of an improved rotary plowing unit, capable of performing the level preparation of rice paddies. SOLUTION: This leveling plate-supporting device of a rotary plowing unit is provided by connecting the rotary plowing unit 1 at the rear part of an agricultural tractor as capable of being lifted up and down, covering the upper direction of a multiple number of plowing claws 8 rotating in a state of up cut and mounted at a plowing shaft 6 with a main plowing cover 9 having a wide width in left and right directions, mounting a rear plowing cover 10 at the rear part of the main plowing cover 9 as freely turning up and down, pivoting a leveling plate 12, forwardly and upwardly inclined, at the rear end of the rear plowing cover 10 so as to be freely turned up and down, and installing a leveling plate-supporting means for supporting the leveling plate 12 in a low pressure state for reducing its own weight by pulling the plate 12 up between a plowing frame and rear plowing cover 10. It is possible to perform a level preparation work of rice paddies by reducing protruded mud soil from left and right both sides of the leveling plate 12 even in the paddy preparation plowing work.
