<p><P>PROBLEM TO BE SOLVED: To provide a walk-behind lawnmower capable of keeping an inclination angle of a cutter constant while being capable of switching to move forward and backward, and tilting the cutter so as to lower the front side in the travelling direction by the switching. <P>SOLUTION: The walk-behind lawnmower capable of switching the travelling direction between a forward movement and a backward movement includes: a body frame (1); travelling wheels (3, 4); a driving part unit (2) attached to the body frame (1) swingably around an axis via pivoting parts (200, 200a) and including a motor (210) and a horizontally rotating cutter (7); a power transmission system (5) for transmitting power of the motor (210) to the travelling wheels (3, 4); a travelling direction switching units (60, 25) for switching the travelling direction between the forward movement and the backward movement; and inclination switching units (25, 251, 26, 27, 27a) swinging the driving unit (2) by switching the travelling direction to tilt the cutter (7) so as to lower the front side of the travelling direction at a required angle, and keeping the angle. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
