Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The field of this invention is a grass clipping storage device for a riding mower such as a garden tractor, lawn tractor, or ride mower.

[Prior art]

In the prior art, as disclosed in Japanese Utility Model Application Publication No. 60-94037, the support member provided at the rear end of the vehicle body is composed of support posts that have a substantially gate shape when viewed from the front, and the left and right lower portions of the support posts are In a riding type lawn mower, which is removably attached to a bracket protruding from the left and right sides of the rear end of the vehicle body by pin connection, and in which the center portion of the entire surface of the left and right grass bags is hooked and supported at the upper left and right sides of the support post, respectively. This is a structure for attaching a grass bag, and as disclosed in Japanese Utility Model Publication No. 182731/1989, the bottom cover of the grass collecting case is opened and closed. That is, there are a replacement method and a dump method.

[Problem to be solved by the invention]

In the conventional technology mentioned above, when the grass bag is full of grass clippings, it is necessary to remove and attach two grass bags each time to remove the grass clippings. In grass mowing work, there is a problem that the number of times the grass bag is used is increased, which impairs work efficiency.In the case of the dump method, the structure is complicated and the cost is high, so it cannot be applied to small riding mowers. There was a difficult problem.

[Means to solve the problem]

This invention takes the following technical means to solve the above problems. That is, a grass cutting device is connected to the lower side of the vehicle body via a suspension link so as to be able to rise and fall freely, and the grass clippings from this grass cutting device are stored in a grass clipping storage device provided on one side of the vehicle body via a grass clippings discharge tube. In the riding mower configured as described above, the grass clippings storage device is provided with a horizontal support shaft on the upper part of a wide shielding frame facing the vehicle body side, and an operating arm and an operation arm extending in the front and rear direction are fixed to this support shaft. A grass clippings container with an open upper surface and a side surface of the shielding frame is locked to a support shaft and an operating arm, and the upper part of the grass clippings container is covered with a head cover that faces the discharge port of the grass clippings discharge tube.

[Effect]

In this invention, when mowing work in the garden is performed and the grass clippings container is full of grass clippings and the grass clippings are to be disposed of as a hanging method, the grass clippings container is lifted and the support shaft and the actuating arm are connected to each other. 1 is removed, the grass clippings container is carried to a predetermined location, the grass clippings are disposed of, and the empty grass clippings container is locked to the support shaft and the operating arm. In addition, when disposing of the grass clippings using the dump method, by rotating the operating arm, the rotating arm rotates and the opening side of the grass clippings storage body moves away from the shielding frame, and the opening side of the grass clippings container faces downward. The grass clippings in the container are discharged downward. Then, when the operating arm is returned to its original position, the opening of the grass clippings container will come into contact with the shielding frame.
It becomes a peeling state.
