When the grass catcher device 7 is installed in its proper position, an opening 17 (described later) serving as a grass receiving port is in close communication with a grass sending port (not shown) of the machine body.

As shown in FIG. 1a, the catcher frame 8 includes a front frame 11 formed of a rod or pipe material into a substantially rectangular shape, and a substantially U-shaped front frame 11 formed of a bent rod or pipe material. It consists of a rear frame 14 with a diagonal support rod 13 pivotally attached to a plane frame 12, and the front frame 11 is attached with the aforementioned locking pieces 10, 10, and insertion joints 1 are attached to the four corners of the front frame 11.
In order to form a joint tube 15a, as shown in FIG. 16 is front frame 1
It is a handle fixed to 1.

Further, as shown in FIG. 1d, the grass collecting bag 9 is entirely formed of a mesh body, and an opening 17 into which the catcher frame 8 is inserted is provided on the front surface thereof. When the grass collecting bag 9 is covered with the catcher frame 8, the inside of the ceiling surface is formed along the flat frame 12 of the rear frame 14, and the front frame 11 is formed along the edge of the opening 17. , and the length in the longitudinal direction is set to substantially match the length in the longitudinal direction of the catcher frame 8. Further, a locking tool 18, which is a semicircularly curved tip of a hard plate, is attached to the edge of the opening 17, and is hooked to the front frame 11 as shown in FIG. 1d.

Hereinafter, the usage and operation of the above configuration will be explained.

First, the tip connecting portion of the plane frame 12, which is a component of the rear frame 14, is inserted into the upper joint pipe 15a fixed to the front frame 11 of the catcher frame 8 that has been transported in a divided state. At the same time, the distal end connecting portion of the oblique support rod 13 is inserted into the joint tube 15a on the lower side while adjusting the angle.
In this way, the assembled catcher frame 8 is inserted into the grass bag 9 from its rear part through the opening 17 of the grass bag 9, leaving the handle 16 intact.
The positions of the edge and the front frame 11 are made to substantially match. In this state, the rear end of the catcher frame 8 has almost reached the rear end surface of the grass collecting bag 9.

Next, the locking tools 10, 10 of the grass collecting bag 9 are hooked onto the front frame 11 of the catcher frame 8. As a result, the grass bag 9 is restricted from moving by the catcher frame 8, and is suitably prevented from falling off. Further, the catcher frame 8 is restricted from extending its entire length in the front-rear direction, and the distal end connecting portion of the rear frame 14 is prevented from coming out from the joint pipes 15a.
