Claims

[Scope of utility model registration request]

The center float 9 is pivoted to the traveling aircraft so that it can freely swing up and down around the rear fulcrum X and can roll freely around the longitudinal axis Y.
A lift control means B is provided which raises and lowers the left and right wheels 8 in the same direction and by the same amount by vertical swinging based on ground pressure fluctuations, thereby maintaining the height of the working device 7 above the ground at a set height. A walk-behind paddy field working machine equipped with a rolling control means A that maintains the rolling posture of the working device 7 on the ground at a set posture by changing the relative height of the left and right wheels 8 through a rolling operation based on ground pressure fluctuations, A bracket 13 is attached to the front end of the center float 9 to enable relative rolling operation around the longitudinal axis Y, and the left and right side walls 15A of the engine mounting frame 15 are attached.
, 15A so as to be able to swing up and down about the horizontal axis, and the center float side bracket 13 is attached to the swinging tip of the engine mounting frame side bracket 16 so as to be able to swing up and down relative to the engine mounting frame. This walking type paddy field working machine has an engine-mounted frame side bracket 16 arranged in such a manner that the outer surfaces of left and right side walls 16a, 16a of the side bracket 16 are in sliding contact or substantially sliding contact with the inner surfaces of left and right side walls 15A, 15A of an engine-mounted frame 15.
