You may comprise so that it may fall down easily to the funnel part 36b.

  Next, the operation of the transplanter 1 according to the present embodiment will be described. When planting seedlings, the operator usually puts his / her feet on the footrest 27 and gets in from the side of the machine body, drops the mud on the shoes at the side step 17 and then sits on the driver's seat 11. An operator seated on the driver's seat 11 starts planting seedlings in the field by the planting unit 7 and performs fertilization with a fertilizer applicator (not shown).

  When the planter loses seedlings in the planting part 7 during the planting operation, the operator takes out the seedlings from a reserve seedling mount (not shown) mounted above the fertilizer tank 30 or makes the machine body 5 perpendicular to the cocoons. The auxiliary seedlings are handed over to the assistant from the heel, and the seedlings are replenished from the seedling supplying step 21 to the planting unit 7 through the front step 15 and the side step 17. At this time, when there is little fertilizer in the fertilizer tank 30, an assistant at the end slides the slide lid 36 forward to the seedling supply position, and places the fertilizer bag on the placement portion 36b and fertilizer The paste fertilizer is supplied to the supply port 32 of the tank 30.

  When the replenishment work is completed, the operator returns to the driver seat 11 and continues the planting work. At this time, if mud gets on the foot during the replenishment work, the leg is extended forward of the sword-like side step 17 cut into the inside of the machine body and the mud is dropped.

  When the operator finishes planting the seedlings in the field, the transplanter 1 is loaded onto the truck while confirming the direction of the front wheels 2 and 2 through the side step 17, and the operation is completed.

  By configuring the transplanter 1 as described above, the width behind the step 19 that requires a width is secured, while the width of the first half is formed narrow, and the step 19 as a whole has a compact and functional shape. I was able to.

  Further, the entire surface of the side step 17 is formed into a slat-like shape, and the front of the side step 17 is located inside the body 5, so that even if an operator gets on and off from the front of the body 5, the mud attached to the feet at the side step 17 is removed. Can be dropped. Furthermore, mud does not accumulate on the step 19, and there is no fear of slipping the foot due to the mud. Moreover, even if mud is attached to the shoes while sitting on the body 5, the mud can be dropped in front of the side step 17 by extending the foot, so that the operation pedal is not stepped on by sliding with mud. Furthermore, the front wheels 2 and 2 can be visually recognized through the side step 17, and loading into a truck is easy, and it is not necessary to make a new hole for seeing through the front wheels 2 and 2.

  In addition, the main step 16 has a divergent shape, and its trailing edge extends to the vicinity of the center of the driver's seat 11 in the longitudinal direction of the fuselage, so that the operator can rest with his feet around the driver's seat and stand up or change the direction of the body. can do. In addition, the foot can be placed comfortably, and mud rebound from the ground is not applied to the operator. In addition, the strength of step 19 can be kept strong in combination with the fact that the side step 17 is formed so as to be located on the outer side toward the rear of the aircraft.

  Further, by forming the front half portion 17f of the outer edge 17d of the side step 17 to be inclined toward the inside of the machine body, the step 19 can be made compact, and the fertilizer tank 30 is sacrificed for its capacity. Without being done, it can be arranged at substantially the same height as the front step 15. In addition, since the lid 36 of the fertilizer tank 30 is slid, the reserve seedling stand provided above the fertilizer tank 30 can also be provided low, and together, these can lower the center of gravity of the machine body 5. . Furthermore, when one foot is placed on the footrest 27, it is easy to place the other foot on the side step 17, and any person can easily get on and off.
