Reference numeral 55 denotes a plurality of weeding devices, each of which is constituted by a weeding body 57 and a weeding rod 59, and is provided so as to protrude forward, for weeding and guiding the planted stem culms. Reference numerals 61a and 61b denote a pair of right and left pulling devices, which are disposed in a backward-sloping manner behind the grass cutting device 57, and are used to pull up the planted stem culms that have been separated by the grass cutting device 55. Reference numeral 63 denotes a reaping device, which is provided at the rear lower part of the pulling devices 61a, 61b, and is used to reap the stem culm pulled up by the lifting devices 61a, 61b from its root portion. Reference numerals 65a and 65b denote a pair of left and right star wheels, which scrape the base of the reaped stem culm that has been reaped by the reaping device 63. 67a, 67b
is a pair of upper and lower lateral feed devices, which are provided at the rear upper part of the reaping device 63 and convey the reaped stem culms cut by the reaping device 63 to one side of the machine body. 69 is a binding device, which is connected to the lateral feed device 67;
A, 67b disposed at the end of the transverse feed device 67
The stem culms conveyed by a and 67b are collected, tied, and released into the field.

The connecting portion 19 is configured as follows. That is, in FIGS. 3 and 4, reference numeral 5 denotes a lower hitch provided on the traveling section 1 side, which projects from the lower front surface of the mission case 3, and has a recessed portion 71 formed at the lower front end thereof. The lower hitch 5 is
It is arranged inside the pair of left and right wheels 9. Reference numeral 7 denotes an upper engaging member provided on the side of the running section 1, and is provided horizontally across the front part of the support bracket 31 fixedly installed above the mission case 3. 15
is a lower engaging member provided on the side of the reaping bundling part 11, which is fixedly installed at the lower part of the reaping frame 13, and is connected to the traveling part 1.
It removably engages in a recess 71 provided in the lower hitch 5 on the side. Reference numeral 17 denotes an upper hitch provided on the reaping binding part 11 side, which is integrally connected to the upper part of the reaping frame 13 and has a downward recess into which the upper engaging member 7 provided on the traveling part 1 side is removably engaged. An entry portion 73 is formed.

In the above configuration, the reaping binding section 1 of the traveling section 1
