After cutting the end side of the with a cutter or the like in the lateral direction, by fixing the end to the field side with mud or the like, since the partial tillage site N and the no-till site F are covered with the sheet 29a at the same time, The weeds that occur at the no-till site F can be suppressed by the multi-effect that covers the no-till site F. The left and right sides of the sheet 29a are also fixed to the field side with mud or the like.

Next, the seedling planting machine A showing a state in which the planting part is removed will be described with reference to FIGS. 6 to 8.

Since the seedling planting machine A has a good front-rear balance with the planting device P connected to the rear of the passenger aircraft J, the passenger aircraft J with the rear planting device P removed is There is a problem that the passenger aircraft J from which the planting device P has been removed cannot be effectively used like an agricultural tractor because it is in a loaded state and cannot stably drive.

In order to solve this problem and allow stable running, as shown in FIG. 6, balance weights 36 that can be selectively swingably fixed to the front position and the rear position around the fulcrum shaft 35 on both the left and right sides of the passenger aircraft J. Is provided.

That is, as shown in FIGS. 6 and 8, lateral mounting rods 37 are fixed to the left and right sides of the passenger aircraft J, respectively.
37 is a bracket which is bent in a U shape in a side view 39
Is stuck. A fulcrum shaft 35 arranged vertically is fitted in a mounting hole provided in the bracket 39, and a pivot boss 41 located in the bracket 39 is rotatably provided by the fulcrum shaft 35. The mounting seat 41a fixed to the outer diameter of the rotating boss 41 has a weight mounting rod 41b extending toward the front side.
The base end is fixed, and the balance weight 36 is removably positioned on the tip end side of the weight mounting rod 41b.

Below the bracket 39, a rotary boss 43 which is fitted into the fulcrum shaft 35 in a rotary position is positioned, and a mounting seat 43a fixed to the outer diameter of the rotary boss 43 is directed forward by a predetermined distance. The base end of a reinforcing rod 43b is extended and the tip side of the reinforcing rod 43b is obliquely upwardly extended. The distal end of the reinforcing rod 43b is fixed to a middle portion of the weight mounting rod 41b.

A vertical fixing plate 39a is fixed to the lower side of the bracket 39, and the fixing plate 39a, the fulcrum shaft 35, and the rotating boss 4 are fixed.
A through hole into which the fixing pin 44 is fitted is formed in the hole 3.

As shown in FIG. 7, when the planting device P is connected to the rear of the passenger aircraft J, the left and right fixing pins 44 are pulled out respectively, and the left and right weight mounting rods 41b are respectively rotated forward, and then the left and right fixing pins are again provided. 44 is inserted and the seedling planting work is performed at the front position of the balance weight 36. At the front position of the balance weight 36, the seedling planter A is rearward by the weight of the balance weight 36 while the planting device P is connected. Since it is in a loaded state and the front-rear balance is good, highly accurate seedling planting work can be performed. At the position where the weight mounting rod 41b faces forward, the reinforcing rod 43b is in a relative position below the step 45 of the passenger aircraft J. Therefore, the reinforcing rod 43b is an auxiliary member for supporting the foot of the driver who gets on and off the step 45. Can also be used as a step.

Then, when the planting device P is removed, the left and right fixing pins 44 are pulled out, the left and right weight mounting rods 41b are respectively rotated rearward, and then the left and right fixing pins 44 are fitted again to rearward the balance weight 36. The aircraft is run at the position, but at the position behind the balance weight 36, the front-rear balance of the passenger aircraft J alone is improved, and when the vehicle is suddenly braked at a relatively high speed, the inertial force causes the aircraft to move forward. The risk of tipping over on the front side due to grounding is prevented, and the passenger aircraft J with the planting device P removed can be effectively used.
