Is a threshing unit 11 with a fryer cylinder 11a
Are distributed.

Further, behind the above-mentioned Glen tank 10,
A vertical transport pipe 12 containing a vertical feed spiral (not shown) is erected, and the paddy that has been threshed in the threshing unit 11 is lifted and transported by a fryer cylinder 11a and stored in a Glen tank 10. The discharge auger 13 discharges from the horizontal feed spiral disposed at the bottom of the discharge auger 13 to the outside through the vertical feed spiral of the vertical transport pipe 12.

As shown in FIGS. 3 and 4, a guide groove 15 for switching the forward / reverse shift lever 14 in the front-rear direction is provided in the front half of the side panel 8 disposed on the side of the driver's seat 9.

And a dial switch group 17 is disposed on the side of the guide groove 15.
Depth manual switch 1 which is located on the right side of the second half portion 15a of the switch, and controls the vertical movement of a depth transport device (not shown).
And a cutting slide switch 19 for controlling the movement of the operating position of a cutting blade device (not shown) in the left-right direction.
Is disposed behind the switching latter half 15a. Reference numeral 20 denotes a dial switch for switching the threshing sorting operation in the threshing unit 11.

The manual handling depth switch 18 includes a switching pressing portion 18a on the deep handling side and a switching pressing portion 18b on the shallow handling side.
And the cutting slide switch 19 is provided with a movement switching pressing portion 19a for shifting the cutting blade device to the left and a movement switching pressing portion 19b for shifting the cutting blade device to the right. The pressing portions 19a and 19b are respectively disposed at left and right positions in the machine body width direction.

At a position below the guide groove 15 formed in the side panel 8, as shown in FIG. 5, a plate-like lever frame 21 having a guide groove 21a for guiding the rod portion 14a of the speed change lever 14 is formed. Are mounted side by side, and a neutral sensor 22 that projects an actuator 22a toward the guide groove 21a is mounted on the upper surface of the lever frame 21 so as to face a space 23 formed between the side panel 8 and the neutral sensor 22. When the shift lever 14 is held at the neutral position, the neutral state of the shift lever 14 is detected by the contact between the actuator 22a and the rod 14a.

As shown in FIG. 6, the neutral sensor 22 is connected in series to an engine start switch 25 via a safety switch 24, the safety switch 24 is closed, and the neutral sensor 22 is Only when the neutral state of the engine 14 is detected and the engine 14 is in the closed state, the starter circuit 2
6 can be activated.

That is, an intermediate relay from the neutral sensor 22 to the starter circuit 26 has an intermediate relay 27.
A start relay 28 is provided, and the start relay 28 is excited through the normally closed contact 27a of the intermediate relay 27, and the normally open contact 28a is switched to the closed contact 28b to thereby start the starter circuit of the engine. 26, a work machine clutch switch 29 connected to a work machine control unit (not shown) is connected between the intermediate relay 27 and a ground point, and the work machine clutch switch 29 is turned on, that is, is drivable. In some cases, when the start switch 25 is turned on, the intermediate relay 27 is excited to switch from the normally closed contact 27a to the open contact 27b, so that the starter circuit 26 does not operate. Therefore, it is possible to solve the problem that the working machine is inadvertently driven at the same time as the start of the engine. Further, it is possible to detect whether the working machine clutch switch 29 is on or off to determine whether the engine can be started. Accordingly, it is possible to avoid the careless driving of other harvesting clutches, pre-processing units, threshing units, and the like, which are controlled by a work machine control unit (not shown) after the engine is started.

In this case, the switching pressing portion 18a on the deep handling side and the switching pressing portion 18b on the shallow handling side of the handling depth manual switch 18 may be alternately switched, and the operating position of the cutting blade device (not shown) is advanced. When shifting the machine to the left or right, the cutting slide switch 1
By switching and pressing the movement switching pressing portion 19a or 19b, the cutting blade device can be shifted to the left or right.

In the operation of the manual handling depth switch 18 and the cutting slide switch 19, the manual handling depth switch 18 is configured to switch in the front-rear direction, and the cutting slide switch 19 is configured to switch in the left-right direction. Therefore, it is possible to quickly switch the control of a desired device without inducing an erroneous operation, with an operational feeling that can easily associate the operating mode of the handling depth conveying device and the cutting blade device controlled by the switches 18 and 19. Can be.

The manual operation switch 18 is located on the right side of the second half 15a of the guide groove 15, and the cutting slide switch 19 is connected to the second half 1 of the switch.
