Description

[Detailed Description of the Invention] The present invention relates to a reversing grass collecting device for a hand tractor.

Conventionally, a reversing grass catcher for a hand tractor has a support frame attached to the front part of the hand tractor via a mounting bracket, and rotating discs at each end of the frame.
It is rotatably supported in a state where it faces front and back, and is eccentric to the right and left sides of the same disc, and a tine bar is attached to each of the three equally divided positions on the same circumference of the disc via a support shaft. It is constructed by installing three tine bars and hanging the tines vertically downward on each tine bar.When harvesting the cut grass by turning it over, the tines are hung down through the tine bars. Since the same process is performed by rotating the tines in the direction of travel from the grounding point while holding them, it is safe to say that the rotational movement of the tines is done in the same way when collecting grass, and that sufficient processing is done in both cases. I couldn't say it.

In the present invention, by configuring the tine bar so that it can be rotated within a certain range around the support shaft, the tines that are vertically installed on the tine bar can be tilted at a certain angle toward the front or rear of the tine bar. It is an object of the present invention to provide a reversing grass collecting device for a hand tractor, which is constructed as follows, and allows the tines to fully exhibit a grass collecting function and a reversing function.
