The utility model provides a formula of walking machine of ploughing can switch into the ground connection posture of removal usefulness or the non - ground connection posture of arable land usefulness with the wheel to can switch the posture of controlling that becomes the posture of controlling that to carry out the clutch pole and restrict the clutch pole. Join wheel and support arm, and constitute the support arm for rotating to the fore -and -aft direction, thereby constitute the ground connection posture for the wheel being switched into removal usefulness, the non - ground connection posture of the usefulness of perhaps ploughing, be equipped with the clutch pole that is used for operating the clutch to the hand in the operation with the handle, this clutch is used for the drive of switch -on and disconnection arable land device, and the constitution does, the clutch becomes " switch -on " when the operation personnel control the clutch pole, the clutch does not become " disconnection " when not controlling the clutch pole, it pins down the board to be equipped with near the clutch pole, it becomes the posture of controlling that can carry out the clutch pole for switching to pin down the board constitution, the posture of controlling with restriction clutch pole.
