Claims (1)

[Scope of utility model registration request] In a walk-behind paddy field work machine that maintains the machine body in a substantially constant working posture with respect to the field surface by vertical displacement of the running wheels, the base end of the vertical movement mechanism of the running wheels swings toward the machine body. a first chain case which is pivotably supported; a second chain case whose proximal end is bendably provided on the distal end side of the first chain case and a running wheel is pivoted on the distal end side; A swinging arm is swingably supported on the fuselage side at a position rearward of the swinging support shaft of the second chain case, and a swinging arm whose distal end side extends forward and is pivotally connected to the second chain case, The running wheels are swung around the pivot on the machine side of the swinging arm, and are moved up and down in the vertical direction during the range of vertical movement when working in paddy fields, and further down beyond the range of vertical movement when working in paddy fields. A walking type paddy field working machine characterized in that the running wheels are configured to be displaced by a large amount of backward movement when the vehicle is in use.
