Bonnet mounting mechanism of riding rice transplanter

The conventional bonnet mounting mechanism is complex and has many components, thus causing hard detachment of a bonnet and hard maintenance. Thus, to solve the problem, a bonnet mounting mechanism of a riding rice transplanter has a fuel tank (136) and a bonnet (22) disposed at an upper front part of a body frame, wherein fixing parts (150) and (140) fixing the bonnet (22) to the transplanter are disposed at front and rear parts of the bonnet (22), respectively, and the bonnet (22), at the rear fixing part (150), is rotatably pivoted on the fuel tank (136) on the transplanter side and the pivoted part of the bonnet (22) is disposed between the rear end and the center of the bonnet (22) and, at the front fixing part (150), detachably fixed to a body cover (20) on the transplanter side and the interface part of the bonnet with the transplanter side is formed of a lever member extending in the longitudinal direction of the transplanter.
