are arranged in order from the front. The sowing section a is provided with a sowing hopper 23 above, a feeding section 24 is connected below the hopper 23, and a chute 25 is communicated with the feeding section 24.
In front of the lower end opening 25 of the chute 25 from the notch of the float m continuous to the lower part of the float m, a sowing groove plate 26 is vertically installed on the float m. The structure is designed to sow seeds. Further, behind the lower end opening 25' of the chute 25, a seeding cover plate 27 is mounted on a float m.
It is installed vertically to cover the soil after sowing. The fertilization section b is disposed behind the sowing section a, and a fertilization hopper 28 is provided at the upper position of the hitch link 10-2 when viewed from the side, and a fertilization delivery section 29 is provided at the bottom of the hopper 28. Two fertilizing hoses 30 on the left and right are connected to the feeding section 29, and the lower end opening 29' of the hose 30 is located behind the rear end of the float m. A fertilizing groove plate 31 and a fertilizing soil plate 32 are disposed on the float m before and after the portion 29', respectively. The weeding section c is arranged behind the fertilizing section b, and the weeding storage hopper 33 is located in front of the fertilizing hopper 28 and is arranged laterally in parallel with the sowing hopper 23. A weeding pipe 34 is connected thereto, and a large number of herbicide spray ports 35 formed at both ends of the pipe 34 are located at both rear ends of the sowing section a and the fertilization section b, which are arranged in parallel in the horizontal direction. Moreover, the herbicide spraying port 35 is formed so that the herbicide spraying direction is diagonally rearward.

In addition, 36 and 37 in the figure are the feeding parts 2 of the sowing part a.
