Three middle and left locking holes 17A, 17B, 17C are formed. On the other hand, in the right link bracket 61R,
An insertion hole 61a for inserting a lower end portion 64c of the slide operation lever 64, which will be described later, is provided. The slide operation lever 64 is inserted through the insertion hole 61a to form the locking holes 17A, 17B. 17C, the slide links 17L and 17R are fixed at three positions of a right position A, a middle position B and a left position C as shown in FIG. It is configured to be fixed at the right three positions.

When the slide operation lever 64 is lifted upward, the locking holes 17A, 17B, 17C
The slide operation lever lower end portion 64c is withdrawn from either of them, and in this state, the slide operation lever 64
When the is rotated left and right, the cutting unit K is configured to move left and right. In this embodiment, the locking holes 17 are used.
A, 17B and 17C are perforated at three places, but may be two or four or more, and the number of holes is not limited.

Regarding the aforementioned slide operation lever 64,
This will be described with reference to FIGS. The slide operation lever 64 is disposed above the right side of the cutting unit K, that is, above the right raising device 22R. The upper portion 64a of the slide operation lever 64 is rotatably supported by a mounting stay 65a locked to the upper right transmission case 65 as shown in FIG. The intermediate portion 64b of the slide operation lever 64 is detachably supported by a stay guide groove 66a fixed to the lower right transmission case 66, as shown in FIG. As shown, any one of the locking holes 17A and 17B of the right slide link 17R.
・ It is fitted in 17C. As shown in FIG. 5, a spring 60 is externally fitted to the lower part of the halfway portion 64b, and is urged to fit into the locking holes 17A, 17B, 17C of the lower end 64c.

As described above, the slide operation lever 64
Are located in the vicinity of the seat 48 of the operation unit S, and from above, the mounting stay 65a, the guide groove 66a, the right link bracket 6
Supported by 1R. When the slide operation is performed, the slide operation lever 64 can be operated while being positioned, and the slide operation lever 64 is lifted and manually pushed and pulled to rotate to a desired position. Part 6
4c is fitted into any of the locking holes 17A, 17B and 17C to lock.

With the above construction, the slide operation lever 46 can be operated to slide to the left and right positions of the cutting unit K from the upper right seat 48 of the cutting unit K of the combine. Since the spring 60 is fitted to the outside of the lock 46, the lock 60 is urged by the locking holes 17A, 17B, and 17C at the lock position, so that removal can be prevented.

[0017]

The present invention is configured as described above.
The following effects are obtained. First, since the slide operation lever 64 is disposed on the upper right side of the reaper K, the slide operation lever 64 remains in the driver's seat when performing a slide operation.
To be operated to lift the sliding operation lever 64 upward, from the locking hole to determine the fixing position of the reaper K, while pulling out the lower end 64c, the slide
The gripping section K can be slid by simply grasping the operation lever 64 and turning it left and right. Further, since a plurality of the locking holes are provided, it can be locked and fixed at a desired position. Thus, the applicability of the field can be improved.

Second, the slide operation lever 64 is
The spring 60 allows the lower end portion 64c to be fitted into the locking hole.
Since the lower end portion 64c is urged, it is possible to prevent the lower end portion 64c from being pulled out of the locking hole.
