Below the front side of the driver's seat 7, a driver's seat step 19 is provided fixed to the vehicle body 2. Each of the clutch pedal 17 and the brake pedal 18 has a window portion 17
The windows a and 18a are vertically movable, and both windows 17a and 18a
Are formed by notches 19a, 19b formed in the driver's seat step 19 and notches 11a, 11b formed in the side steps 11, 11.

Below the engine 5, as shown in FIG. 8 and FIG. 9, a transmission 20 is superposed and arranged. Between the input shaft 20a of the transmission 20 and the output shaft 5a of the engine 5, as shown in FIG. 1, a multistage speed change belt transmission mechanism 21 is provided, and the multistage speed change belt transmission mechanism 21 is shown in FIG. As also shown, it has a function of selectively slidingly contacting with a plurality of (three) cams 22 attached to the sub-transmission lever 15 and transmitting the gear shift through the tight arm 23. Then, the clutch pedal 17 is depressed during this gear shift operation.

On the other hand, in the transmission 20, as shown in FIGS. 3 to 5, a bevel gear 25 is fixedly mounted on a transmission shaft 24 provided in parallel with the input shaft 20a, and a bevel gear 26 meshing with the bevel gear 25 is provided. An output shaft 27 for driving the planting device, which is fixed, is provided so as to be orthogonal to the transmission shaft 24, and the transmission mechanism 2 is provided at a side end portion of the transmission shaft 24. The speed change mechanism 28 moves a gear group slidably in the axial direction of the speed change shaft 24 and meshed with a speed change gear fixed to the input shaft 20a so as to be disengaged by a shifter shaft 29 in a stepwise manner. It is designed to be moved by the shift fork 30. The outer end of the shifter shaft 29 is pivotally attached to the lower end of a swing arm 32 which is pivotally supported by a bracket 31 fixed to the mission case via a shaft 31a, and a stock shift lever 33 is fixed to the upper end of the swing arm 32. There is. The inter-stock gear shift lever 33 projects laterally from the transmission 20 and extends to the vicinity of the window 17a of the clutch pedal 17, and when operating the inter-stock gear shift lever 33, the bonnet 10 is opened and the side step 11 is also opened. It rotates in the up and down direction to perform three-speed stock shift.

In addition, in the above-mentioned embodiment, the stock shift lever 33 may be configured to project toward the window portion 18a side of the brake pedal 18.

Then, the bonnet 10 and the side step 11 are opened as shown by the phantom lines in FIGS. 6 and 9, and the stock shift lever 33 is rotated in the vertical direction to select any one of the three steps. And the side step 11 is closed and the rice planting work is restarted. At this time, since the traveling speed of the passenger car body 1 is constant and only the rotation speed of the planting device 9 is changed, the intervals of seedlings to be planted are changed to be wider or narrower than before.

In this way, when operating the stock shift lever 33, the bonnet 10 and the side steps 11 are moved up and down in a wide space opened to the front of the vehicle body, so that the operation is easy and can be performed lightly and reliably. In addition, the stock shift lever 33
Is provided in the bonnet 10 on the front side of the driver's seat step 19, so that the operator's foot does not accidentally come into contact with the inter-stock shift lever 33 and cause a malfunction. Further, since the transmission 20 is superposed and arranged below the engine 5, the center of gravity of the front and rear of the traveling vehicle body 1 is shifted to the front,
Even if the front-rear length of the passenger car body 1 is shortened, it is possible to maintain a balance with the planting device 9, so that the entire riding-type rice transplanter can be downsized.

[Effect of device]

As described above, according to the interplant strain adjusting device in the riding type transplanter of the present invention, the following effects can be obtained.

The inter-stock shift lever is projected laterally from the transmission and is arranged in the vicinity of the window portion of the operation pedal, and the window portion of the operation pedal is formed by the step provided on the side of the openable hood and the step of the driver's seat, Since the stock shift lever is operated with the bonnet open, the operating load is reduced, the operability is improved, and the stock shift operation is reliably performed.

Since the inter-stock shift lever is provided in the bonnet in front of the driver's seat step, it does not interfere with the feet of the operator, and there is no risk of erroneous operation of the inter-stock shift lever by the operator's foot.

Since the transmission is superposed and arranged below the engine, the front load of the passenger car body becomes heavy and the front and rear balance with the planting device is improved, the front and rear length of the passenger car body can be shortened, and the entire transplanter can be downsized. .

If the transmission overlaps the lower part of the engine, the transmission will be located in front of the driver's seat, and it is unavoidable that the gear shift operation of the stock shift lever is usually difficult. By opening and closing the one-piece bonnet, the stock step shift lever is covered by the side step section during work to prevent accidental erroneous operation, and the side step is released at the same time by opening the bonnet during the stock step shift operation. The gear shift lever can be operated safely and reliably in a wide space.
