As the sowing machine, as shown in Japanese Patent Application No. 1-316888 filed by the applicant of the present invention, a chute for supplying cut grass to the ground is provided at the rear of a wheel-running type fuselage. Tensioners have been proposed. In the configuration according to this proposal, the wheels of the body do not pass through the cut turf laid on the ground, so that the state after the laying is easily maintained in a good state.

〔発明が解決しようとする課題〕[Problems to be solved by the invention]

In other words, the ground on which cutting turf is laid is usually cultivated on the ground surface in advance to improve rooting after laying, so the trace of wheel passage is clearly recessed, and the cut turf supplied to it is also There is room for improvement because it is likely to be depressed and adversely affect the laid condition.

本発明は上記不都合の解消を目的とする。 The object of the present invention is to eliminate the above disadvantages.

〔課題を解決するための手段〕[Means for solving the problem]

The present invention relates to a sowing machine, wherein a device for supplying cut grass to the ground is provided at a rear portion of a traveling body, and between a supply device and a traveling device of the aircraft, in a front-rear direction, on a ground after passing the traveling device. A grading mechanism that acts on the ground, the crushing tool that tills the ground, a crushing roller that crushes the ground tilled by the cultivation tool, and a ground that is crushed by the crushing roller. It is characterized in that grounding members for roughening the surface are arranged in this order from front to rear.

According to the configuration, even if the ground to be cut and laid is recessed due to the passage of the traveling device, the depression is eliminated by the tillage action by the tillage implement, and the pressure-reducing roller of the pressure-reducing roller that represses and leveles the tillable ground. By the action, it is re-leveled before cutting turf supply.

Furthermore, since the ground surface after passing through the pressure-reducing roller can be roughened by the grounding tool, the degree of rooting is improved compared to a case where grass is grown on a smooth ground surface after passing through the pressure-reducing roller without this grounding tool. Advantageously, such as the roots extending to the ground early and being integrated with the ground early, it is possible to adjust the recessed portion by the traveling device to the finished state of the ground where the wheels do not pass, at a higher level.

〔発明の効果〕〔The invention's effect〕

Therefore, while the cut turf is supplied to the ground after passing the traveling device, the conventional turf laying state is improved by improving the conventional inconvenience, and the turf surface after the laying is not partially depressed. The practically excellent sowing machine which can minimize the difference in the growth state between the ground passing through the traveling device and the other ground is realized.
