草案内方向を変更自在である。 The present invention solves these conventional problems, and its feature is that three cutting blade bodies 7, 8, 9, which are rotatable around the vertical axis, are installed below the mower deck 6. Each cutting blade body 7, is provided with a guide plate which is arranged at intervals in the direction and guides and discharges the grass clipped by each cutting blade body 7, 8, 9 rearward on the mower deck 6.
In the device in the mower's cutting blade, each cutting blade body 7, 8, 9 is provided with at least one blade corresponding to each cutting blade body 7, 8, 9.
In order to make it possible to change the state in which the cut grass cut by the mower deck 6 is dispersed over substantially the entire width behind the mower deck 6 and the state in which it is gathered in one place, each of the guide plates can independently change the direction within the cutting draft.

設定する。 The third left and right guide plates 28 and 29 are arranged on the left and right sides of the third cutting blade body 9, and the former determines the direction of the grass clippings released from the third cutting blade body 9.
also controls the direction of the grass clippings from the first cutting blade body 7;
The right guide plate 29 sets the right end of the grass clipping discharge width of the entire mower.
次に、各案内板による刈草の放出態様を示す。 Next, the manner in which grass clippings are released by each guide plate will be shown.

で分散される。 The position at which the mower 5 can release grass clippings differs slightly depending on where it is mounted on the tractor 1, but in the case of a mid-mount type, the rear wheels 4 are located behind both ends of the mower 5, so the maximum spread range of grass clippings is Second
This is the range (P) shown in the figure. Each guide board 25, 2
When 6, 27, 28, and 29 are arranged at the positions of the broken lines, the grass clippings are dispersed within the range (P) without clumping in one place.
刈草を略中央に集草する場合は、各案内板２
５，２６，２７，２８，２９を仮想線位置に配置

can change the internal direction of the cutting draft independently,
The cut grass cut by each cutting blade body 7, 8, 9 is guided so as to be changeable between a state in which it is dispersed over substantially the entire width behind the mower deck 6 and a state in which it is collected in one place.
更に、前記態様に限らず、５枚の案内板の刈草
案内方向を種々変更することにより、刈草の集草
位置を左右に変更したりその範囲を広狭にしたり
することができる。 Further, the present invention is not limited to the above-mentioned embodiment, and by variously changing the direction within the cutting draft of the five guide plates, it is possible to change the grass cutting position to the left or right or to widen or narrow the range.
尚、第２刈刃体８からの刈草放出案内として、
第１、第３刈刃体７，９の場合と同様に第２右案
内板を設けても良い。 In addition, as a guide for releasing grass clippings from the second cutting blade body 8,
As in the case of the first and third cutting blade bodies 7 and 9, a second right guide plate may be provided.

いようにすることにより解消できる。 The mower deck 6 of the mower 5 is formed in the shape of a mountain protruding from the front center in a plan view, but with such a shape, the grass flows outward along the front side plate 22 before being mowed, causing it to curl. Mowing performance may deteriorate. Further, the direction and degree of the grass falling tends to be uneven. Such problems can be solved in the seventh
As shown in the figure, the front plate 22' on the front side of the mower deck 6' is arranged at right angles to the direction of travel, and all the plants are pushed forward by approximately the same amount to prevent the grass from flowing sideways. This can be resolved by

なつている。 By the way, in the case of mid-mount type mower 5,
In order to attach and detach it to the tractor 1, it must be inserted and removed from the outside and below the tractor 1, but normally, the front and rear gauge wheels 16 and 21 of the mower 5 only roll in the front and rear directions, but in the left and right directions. The structure is not suitable, making it extremely difficult to attach and detach the mower 5.

下方へ挿脱する際にキヤスタとして作用する。 The height of the gauge wheel 21 can be adjusted by rotating the horizontal shaft 61 via the lever 65, and by separating the lever 65 from the positioning member 67, the horizontal shaft 61 and the cylinder body 62 can be adjusted. By rotating about the vertical axis 60, the gauge wheel 21 rotates approximately 90 degrees from the solid line position in FIG. 10 to the imaginary line position. The gauge wheel 21 at this imaginary line position is free as there is nothing to fix the position, and the mower 5 is moved by the tractor 1.
Acts as a caster when inserted and removed downward.
