トの点でも高くなる。 BACKGROUND ART Conventionally, a cutting machine for harvesting soybeans, beans, etc. is generally equipped with a cutter on the center line in front of a moving mobile agricultural machine. The disadvantage of such conventional work machines is that the stalks of soybeans, etc. are cut with the front cutter located on the center line, and the workers and mobile agricultural machinery move from behind, so there is a risk of trampling on the cut stalks, etc. There is a risk of grains falling off. Therefore, it is difficult to perform efficient cutting with less shedding. Therefore, a discharge mechanism and a conveyance mechanism are required to discharge the cut stems etc. to the rear and sides, which complicates the structure and increases the weight.It is difficult to say that it is the best in terms of operability, and furthermore, it is costly. It will also be higher in points.

得る如くした農耕作業機を提供するにある。 The purpose of the present invention is to make the width of both the left and right wheels of the main body of a mobile agricultural machine, such as the main body of a power tiller, approximately equal to or narrower than the width of the ridge in which grains to be harvested are planted, and to install a frame in front of the main body. A guide member for raising the grain stalk, a reaping cutter for cutting the stalk, and a guide member for guiding the stalk to the cutter are provided on the side of the grain stalk, and the grain stalk is raised laterally and moved. Prevents stepping and shedding caused by the main body,
Cut the stems with a cutter while being guided by a guide provided on the side, align the cut stems by falling them to the outside of the wheel, and prevent interference between the main body and the cut stems, making the cutting work more efficient. To provide an agricultural working machine which can perform the above operations without causing grain shedding and which can be designed with a simple structure.

ることとなる。 Next, to explain its functions and effects in detail, when the main body 1 is moving, the propulsion drive wheels 9, 9 do not step on soybeans, etc. in the ridges, but grip the ditch and move forward reliably. Along with this, the raising guide member 16,
The stems are raised at 17 and 19, and those on one side are guided laterally by the guide bar 30 to prevent stepping and shedding by the propulsion drive wheel 9-1. Guide members 17, 19
The stem between them is cut into 2 by guide members 28 and 29.
The cutter 20 and the root of the stem interfere with each other in the vicinity of the opening at the rear and are cut, and the cut stem is guided by the guide member 2 as the cutter rotates.
8,29 It is sent rearward through the rear opening and falls outward. Therefore, even if the propulsion drive wheel 9-2 runs from the rear, it will not interfere with it, and even if there is a temporary interference, it will only interfere with the stem part, and the grains will be prevented from falling off. The above-mentioned cutting work and stem guiding work can be carried out reliably since dancing is prevented by the balance weight 31.

大の利点を有する。 As is clear from the above, according to the present invention, the cutting work can be carried out efficiently without stepping on the cut stems, etc. or causing shedding, and the cut stems, etc. do not require a conveying device or a guide device. It has many advantages, such as being able to be discharged sideways and arranging without any problem, having a simple structure and achieving the above with a minimum number of parts, and also being able to reduce costs.
