Description

[Detailed description of the invention] This invention consists of a rotating blade that rotates along a horizontal plane and a rotary blade that rotates along an inclined plane that is inclined with respect to the horizontal plane, at a position closer to the front of the aircraft that travels with the traveling unit. The rotary blades are installed in parallel on the left and right when viewed from the front, so that the grass growing on the top of the ridge and the grass growing on the slope of the ridge can be cut at the same time. This invention relates to improvements to mowers used to cut grass.

With the mower configured as described above, the grass that is cut from the slope of the ridge by the rotary blade that acts on the slope of the ridge falls into the field, making it troublesome to dispose of it afterwards. There's a problem.

The purpose of the present invention is to solve these problems, so that the grass cut from the slope of the ridge is sent up to the top of the ridge, so that it is combined with the grass cut on the top of the ridge. The goal is to propose new means.

In order to achieve this object, the mower according to the present invention has a rotary blade that rotates along a horizontal plane and a rotary blade that rotates along a horizontal plane and a mower that runs along a slope that is inclined with respect to the horizontal plane. In a lawn mower equipped with a rotary blade that rotates and is installed side by side on the left and right when viewed from the front, a feed plate that rotates integrally with the rotary blade is mounted on the upper surface of the rotary blade that rotates along the slope. It is characterized by being constructed by providing a sweepback angle in the direction of rotation of the rotor.

Next, an example of implementation will be described with reference to the drawings.

When driven and rotated, the upper surface 90 of the ridge 9 and the ridge 9
Grass growing on both the slope 91 and the slope 91 can be cut at the same time.

At this time, the grass cut from the slope 91 of the ridge 9 by the rotary blade d is sent up to the upper surface 90 of the ridge 9 by the feed plate e provided on the upper surface of the rotary blade d, and It merges with the grass growing on the upper surface 90 of the ridge 9 and is cut down by the rotary blade c, accumulates on the upper surface of the ridge 9, and is post-processed together with the grass cut down by the rotary blade c. The state will be as follows.

As explained above, the lawn mower according to the present invention has a rotary blade that rotates along a horizontal plane and a rotary blade that rotates along an inclined plane that is inclined with respect to the horizontal plane, at the front part of the machine body that runs by the traveling mechanism. In a lawn mower, which is installed side by side on the left and right when viewed from the front, a feed plate that rotates together with the rotary blade is placed on the upper surface of the rotary blade that rotates along the inclined surface, and is retracted in the direction of rotation of the rotary blade. Because the structure is equipped with corners, when grass is cut from both the top surface of the ridge and the slope at the same time, the grass cut from the slope of the ridge is cut from the top surface of the ridge. The grass joins the grass that is being cut and accumulates on the upper surface of the ridge, making post-treatment of the cut grass easier.
