Claims

[Claims for Utility Model Registration] (1) An aircraft body having drive wheels that are rotationally driven by an installed engine, which are provided on the aircraft body perpendicular to the traveling direction of the aircraft and are rotationally driven by the engine. a top surface reaping device in which a plurality of top surface cutting blades having cutting blades whose tips are spread outward from each other are oriented in a radial direction on a rotary drive shaft, and their base ends are loosely attached with pins; A lawn mower comprising a case rotatably provided adjacent to the lawn mower, and a slope cutting device having a plate-shaped rotary blade attached to a vertical drive shaft provided in the case and rotationally driven by the engine. (2) A plurality of upper cutting blades of the upper cutting device are arranged in parallel in the axial direction with respect to the rotary drive shaft, and the rows of the upper cutting blades are shifted in phase, and the mounting positions of the front and rear upper cutting blades are shifted. 2. The mower according to claim 1, wherein the mower is installed in a mower. (3) The case of the slope reaping device is rotatably connected to the machine body by a hinge, and the chain fixed to this case is attached to a chain sprocket equipped with a motor installed on the machine body, so that the angle of inclination of the case can be adjusted as desired. Claim 1 characterized in that the angle can be set to
Lawn mower as described in section. (4) A claim characterized in that an output drive shaft provided on the aircraft body and connected to the engine to be rotationally driven and an input shaft connected to the vertical drive shaft of the case are connected by a telescoping shaft via a universal joint. The mower described in paragraph 1. (5) The rotational drive shaft of the top surface reaping device is characterized in that it rotates in a direction in which the tip of the top surface cutting blade scoops in the direction of movement of the machine, and the vertical rotation shaft of the slope surface reaping device is rotated in a clockwise direction when viewed from above. The mower according to claim 1.
