Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a riding mower that cuts grass such as lawns with a mower attached to a vehicle body frame and stores the grass in a grass collecting container.

(Prior art) A conventional riding mower has an engine mounted on the rear part of a body frame on which the front and rear wheels are suspended, and a control device mounted on the front part. A grass collecting container is attached to store the grass cut by the mower, and the rear wheels serve as driving wheels and steering wheels.

(Problems to be Solved by the Invention) In the above-mentioned prior art, the grass collection container is located behind the rear wheels, so the amount of storage in the vehicle increases (and the front-to-back balance of the vehicle body is lost, so the capacity must be reduced). Of course, 4.
Another problem was that the overall length of the device was long.

This problem can be solved to some extent by placing the control device in the center of the vehicle body and mounting a grass collection container at the front of the vehicle body. However, even if the grass collection container is mounted on the front of the vehicle body, if the bottom height of the container is located higher than the front wheels, its capacity cannot be increased very much, and progress in streamlining the work is unlikely.
