2. Description of the Related Art Conventionally, a technique related to a Lonemore catcher box has been known. However, in the conventional Lonemore catcher box, when discharging grass clippings from the catcher box,
Two types of operations were required: unlocking the lock fittings that lock the lid, and then unlocking the lid with the box opening / closing lever. In order to simultaneously perform the above two operations, the link mechanism is complicated. In addition, although a catcher box full sensor has been provided in the past, there is a problem that the retention status of grass clippings inside the catcher box is different because the type of grass and the specific gravity of the grass clippings are different. It was.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a tractor equipped with a lawn mower is operated by one operation of a box opening / closing lever provided on the side of the driver's seat to release the lock fitting of the lid and rotate the lid. Both of them can be opened, and conversely, in the case of closing, the lid is first closed and then the lock fitting can also be engaged by one operation of the box opening / closing lever. . In addition, the full sensor inside the catcher box that detects whether or not the lawn is full can be slid up and down along the sensor bracket to change the position. Even if there is a difference in the specific gravity of the grass, the grass can always be filled up to the maximum capacity of the catcher box B.

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. In Claim 1, Lonemore M
In the catcher box of the Lonemore, which throws the lawn cut by the thrower S into the catcher box B by the thrower S arranged on the side of the lawn mower M, the cover of the catcher box B is provided so that the cut grass in the catcher box B can be released. 12 is configured to be rotatable and openable, the lid 12 of the catcher box B can be opened and closed by operating the box opening / closing lever 10, the operation of the box opening / closing lever 10 is configured in two stages, and the lid is opened by the first operation.
