The handle 79 is made of a pipe or plate material and is bent in the same direction at both left and right ends to form a gate having a horizontally elongated hand receiving portion 80. It is located at the rear and the front operation wall 9
The base is fixed to the machine frame, located above the upper surface of the machine.
Then, the handle depth adjusting transport device (not shown) constituting the harvested grain culm transport device 19 of the cutting unit 2 is manually moved and adjusted above the left end portion of the handle 79 in the forward direction. A manual adjusting means 81 (a lever, a switch, etc.) is provided for adjusting the traveling direction of the airframe gently at the front of the center (in the embodiment, the left and right side clutches are turned on and off). 82 (lever, switch, etc.) is provided detachably.

Another Embodiment 1 An operation lever for changing the direction of movement of the machine body by raising and lowering the mowing unit 2.
8, tilting the aircraft to the left changes the traveling direction of the aircraft slowly to the left, tilting the aircraft to the right gradually changes the traveling direction of the aircraft to the right, and tilting the aircraft forward reduces the forward speed of the aircraft to a constant speed. A switch lever 83 is provided to reduce the reverse speed of the fuselage to a constant speed when tilted rearward. Although the vehicle speed is reduced to a constant speed, a configuration may be adopted in which the vehicle speed is reduced to a stepped or unrestricted floor. Further, in the embodiment, the lever is used, but a push button type switch or the like may be used, and the invention is not limited to this.

Further, if the top of the switch lever 83 is spherical or mushroom-shaped, the operation is easy. Therefore, the vehicle speed and the traveling direction of the aircraft can be decelerated or gently set in advance, so that the aircraft can be easily aligned with the grain culm in the field, and a collision during work on the ridge can be safely avoided. Can work.

Next, the operation will be described. First, the driver opens and closes the door 27 of the cabin 14 to open the seat 5.
When the engine is started by depressing the parking brake pedal 70 to depress the key into the key switch 56 and starting the engine, the power output from the engine is transmitted to the rotating parts of the body via the transmission mechanism.

Then, the throttle lever 50 is turned to select the engine at a predetermined rotational speed, and the sub-transmission lever is rotated.
By rotating 45 forward, for example, selecting the standard, and further operating the threshing lever 46 and the cutting lever 47, the threshing unit 3,
When the mowing unit 2 is driven, the machine conditions and the like are displayed on the display devices 37, 38, and 39 of the instrument panel 36. Also, depending on the lodging conditions of the grain culm in the field, it is necessary to increase or decrease the speed of the raising lug 16, but when performing the shifting operation, turning the shifting lever 75 forward or backward, The operating arm 78 connected thereto operates to operate the transmission mechanism 74 of the transmission gear box 73 to increase or decrease the speed to raise and lower the speed of the lug 16 to select a desired speed. it can. When performing this operation, the driver's left arm is located on the front side of the vehicle speed shift lever 6 located at the neutral position.
Speed change operation can be performed smoothly.

When the preparation for the harvesting work is completed, the depressing of the parking brake pedal 70 is released, and then the gearshift lever 6 is released.
Is turned to the front side to advance the fuselage and the operation lever 8
In the fore-and-aft direction to determine the position of the reaper 2, or incline left and right to change the traveling direction of the aircraft and
Is adjusted to a predetermined distance. Then, cause case 1
Rag 16 moves diagonally rearward and upward along 7
The root portion of the cereal stem caused by the above is cut by the reaper 18 and is inherited by the reaper 19 and transported rearward and upward.

Then, the cereal culm that has reached the conveyance end portion is nipped by the automatic cereal culm feeding device 20 and conveyed backward, sent to a culm processing device such as a cutter for processing.
The ears of the culm are fed into the handling room and threshed. Processed products such as grains generated by this are separated by air and are separated into grains and straw chips, and the grains are sent to the tank 4 by the transport device and stored therein. Thereafter, when the kernels in the tank are full, the driver interrupts the harvesting operation and performs the operation of discharging the kernels. Is discharged outside the machine, so that it may be transferred to a truck such as a truck.

In such a harvesting operation, when the cutting height of the grain culm is made uniform, the automatic cutting height adjusting switch 71 is turned on, and when the handling depth is automatically performed, the automatic cutting is performed. The depth switch 72 is turned on. When operating the switches 71 and 72, if the shift lever 6 is being rotated, the driver can easily view the switches 71 and 72 and easily perform the on / off operation of the switches 71 and 72. Can be. In addition, during harvesting, for example, when the lodging of the cereal stalk is large, it is necessary to match the weeding body 15 located on the leftmost side of the uncut culm side with the streak. Since the width of the wall 9 in the front-rear direction is small, the driver can approach the front side and the alignment can be facilitated. Further, it is easy to depress the parking brake pedal 70.

Further, on the upper portion of the left end of the handle 79 in the forward direction, the harvested grain culm transport device 19 of the mowing section 2 is provided.
Depth manual adjustment means 81 for manually moving and adjusting the handling depth adjusting conveyance device, which is provided at the front of the center portion, is capable of gently changing the traveling direction of the machine body.
2 is provided detachably, so that the operator
By moving the scented hand in the lateral direction, operations such as manual adjustment of the handling depth and alignment can be simplified.
