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 and stores the grass in a grass collection container.

(Prior art) A conventional riding mower has an engine mounted on the rear of a vehicle body that spans the front and rear wheels, a control device mounted on the front, and allows grass clippings to be taken out from the front. A grass container is attached to the rear of the vehicle 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 prior art, the grass collection container is located behind the rear wheels, and as the amount of stored grass increases, the longitudinal balance of the vehicle body will be lost, so the capacity must be reduced. Moreover, there was a problem in that the overall length of the device was long.

This problem is solved by placing the control device in the center of the vehicle body.
This problem can be solved to some extent by installing a grass collection container on the front of the vehicle. However, if the grass collection container is mounted on the front of the vehicle body, the exhaust air after transporting the grass clippings will be applied to the operator behind it. Although it is conceivable to extend the exhaust duct from the grass collection container to the rear of the seat, placing it on the side of the seat will impede the operator's ability to get on and off the vehicle and work.
