があった。However, in the above-described conventional structure, when the seedling planting apparatus is mounted, the front-rear balance of the body can be better maintained by the weight member on the front side of the body. However, when running on a road, for example, with the seedling planting device removed from the body, the body leans forward when braking, because the body is in a pre-balanced state with the center of gravity closer to the front side. There was a fear.

機体全体の重量の軽量化を図ることができる。(Operation) According to the structure of the first aspect of the present invention, the weight member can be detachably supported by the rod-shaped frame provided at both ends of the central transmission case and connecting the pair of axle cases. Therefore, when the seedling planting device is mounted on the rear part of the fuselage, the weight member should not be mounted on the rod-shaped frame, and the center of gravity is located on the front part of the fuselage so that the overall front-rear balance is appropriate. There is a state. On the other hand, when the seedling planting apparatus is detached from the body, the front-rear balance can be appropriately set only by the body by appropriately attaching the weight member to the rod-shaped frame. Also, if a part of the balance weight mounted on the front side of the fuselage is mounted on the rod-shaped frame side, the time required for attaching and detaching the weight member can be reduced as compared with the case where the weight member is separately mounted on the rod-shaped frame. ,
The weight of the entire body can be reduced.

る。Next, the drawing marker 15 will be briefly described. As shown in FIGS. 1 and 8, the body 3 supports a pair of left and right drawable markers 15 that can be raised and lowered. The marker portion 16 at the tip of the drawing marker 15 is configured to have a tapered shape made of rubber or plastic and a relatively high flexibility. The marker portion 16 is fastened and fixed by a screw 19 so as to be able to change its fixed position while being inserted into a through hole 18 at the free end of an arm 17 that can swing up and down with respect to the body 3. According to this configuration, the tip of the marker portion 16 is not sharp but relatively round and thick, so that the tip is not pulled in a state where the tip pierces the rice field, and thus the marker is not stabbed in the state where it is stabbed. It is possible to suppress the occurrence of the problem that the marker line is unduly bent due to the increase in the pulling resistance of the part,
There is an advantage that the marker line on the rice field becomes clear.
