<p><P>PROBLEM TO BE SOLVED: To provide a mower capable of further increasing the inclinable angle in a vertical direction of a movable frame provided with a rotary blade on the mowing side of a tilted surfaces, in the mower capable of performing the mowing work on both of a horizontal surface and the tilted surfaces simultaneously. <P>SOLUTION: This mower includes a main frame (2) equipped with a main rotary blade and subsidiary rotary blades (36) capable of rotating on surfaces having different angles from that of the main rotary blade. Each of the subsidiary rotary blades (36) is provided on movable frames (3, 3a) mounted in parallel on both sides of a main frame (2) so as to be able to swing in the vertical direction through a hinge part (31). On the main frame (2) side, a main driving shaft (22) driven by an engine is provided, the movable frames (3, 3a) have driven shafts (37) moving in association with the subsidiary rotary blades (36), the main driving shaft (22) and driven shafts (37) are provided as shifted by a prescribed distance, and between both of the shafts (22, 37), drive shafts (38, 38a) are connected through universal joints (220, 370). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
