(Problems to be Solved by the Invention) However, when transplanting with the above transplanting machine, the drive wheels and the tail wheels are caused to run along the grooves between the ridges. Because, in other words, because the drive wheels ahead, it is difficult to obtain the straightness of the aircraft,
If the rows of seedlings planted by the transplanted nails become irregular, and if the number of seedlings on the seedling mounting table is reduced and the seedlings are to be connected, the seedling mounting table will be clawed at the upper part of the machine. Since it is arranged on the front side of the drive mechanism, it is not only difficult to carry out the splicing operation to the seedling mounting table, but also involves danger. Further, in the above transplanter, since the tail wheel is supported at the rear position of the drive wheel, such as when the aircraft turns to the field edge, so that the tail wheel runs over the ridge, It is necessary to turn the aircraft with the rear side of the aircraft lifted upward through the steering handle, but the rear side of the aircraft supports a heavy object such as the claw drive mechanism of the transplantation device. Therefore, there is a problem that it is difficult to perform the turning operation of the body and the turning property is poor.

In addition, the driving wheel (5) is supported at a front portion of the transmission case (4) by a support arm (81) swingably supported at a lower side of the front frame (1A). A detection roller (8) having an inter-strain detection switch (not shown) for controlling the interplanting of potted seedlings by the transplanting claws (36) of the transplanting mechanism (3) while rolling on the upper surface of the ridge (A). The driving mechanism of the transplant mechanism (3) is intermittently controlled by an inter-strain detection signal output from the switch in conjunction with the rotation of the detection roller (8). Intermittent control adjusts the spacing between the plantings by the transplanting nail (36) to a predetermined pitch interval, and is linked to the front end of the support arm (81) by the vertical movement of the detection roller (8). And attach the detection rod (82) that swings up and down,
The distal end of the detection rod (82) is connected to a valve device (83) for controlling a vertical lifting / lowering cylinder (not shown) of the transmission case (4) incorporated in the transplanter. The cylinder is controlled by opening and closing the valve device (83) by the vertical swing of the detection rod (82) interlocked with (8), and the transmission case (4) is swung in the vertical direction accordingly. The drive wheel (5) is moved up and down by the swing of the transmission case (4) to adjust the overall height of the body (1), so that the drive wheel (5) is disposed near the rear of the drive wheel (5). The planting depth of the pot seedling by the transplanted nail (36) is controlled to a predetermined depth.

In addition, a hydraulic pump (14) and a dynamo (15) are provided on one side of the engine (2) above the front frame (1A).
And the hydraulic pump (14) and dynamo (15)
Are driven directly by the engine (2) irrespective of the transmission system on the main clutch side provided in the transplanter, and the main clutch is temporarily stopped so as to temporarily stop the body (1). Even when the power is turned off, the hydraulic pump (14) and the dynamo (15) can be driven to enable hydraulic operation and power generation operation. In this way, for example, in the case where the above-described electrothermal multi-cutter (38) is provided, even if the multi-cutter (38) is always energized, the dynamo (15) is directly driven by the engine (2). Since the power is driven and the power is generated even when the main clutch is off, the problem of running out of the battery can be eliminated.
