2. Description of the Related Art A conventional reel mower in which a plurality of reel mowers are arranged on a conventional airframe is used for cutting grass after mowing as it is on grass.
Or because they were left in the turf, the cut turf left on the turf was heavily discolored and disfigured. Also,
The cut grass that entered the grass was piled up and hindered the growth of the grass. Therefore, a small bucket is mounted on each reel mower, or a hopper is provided on the fuselage (see Japanese Unexamined Patent Publication No.
1166752), a technique for collecting cut grass is known.

[0003]

However, as in the former case, since the buckets mounted on each reel mower are small, the buckets are immediately filled with mowing grass when mowing, and the buckets must be removed and discharged. However, the discharge work was very hard work. When a bucket is provided on the reel mower, a space for arranging the bucket is required, and it is necessary to provide an overlapping portion in the adjacent reel mower so that there is no uncut in the width direction. The interval must be separated by the bucket, and if the interval between the front and rear is long, not only the overall length becomes long, but also uncut leaves are likely to occur when turning, and in order to eliminate this, it is necessary to lengthen the overlapping part, There was a problem that the cutting width of the rice became short. Also, as in the latter technique, a hopper is provided on the fuselage, the hopper and a reel mower are connected by a duct, and a lawn mower is suctioned by a reel mower by driving a suction fan provided on the hopper. Since the suction fan is located far away from the reel mower, the suction path becomes long, and since it is provided on the hopper, it also sucks the air in the hopper, so a powerful suction fan is required. The hopper must have a closed structure,
Needs a seal member with few seams, is expensive,
The suction efficiency was also poor.

As described above, the present invention has the following advantages. That is, since the suction cover is provided in each of the plurality of reel mowers in the direction in which the cut grass is scattered, the cut grass is less likely to be scattered in areas other than the mower, and the discharge port of the suction cover and the suction port of the blower disposed on the machine body are separated. Because of the communication through the duct, the cut grass is sucked into the blower by driving the blower, so that the cut grass is less likely to remain on the field scene, and the finish is beautiful. Also, a hopper is arranged on the fuselage, and the upper entrance of the hopper and the discharge port of the blower communicate with each other via a duct, so that the cut grass is stored in the hopper, and the cut grass remains on the cut surface of the field. Thus, the cut grass can be collectively discharged to a desired position without damaging the aesthetic appearance. And since the blower is located between the reel mower and the hopper, the suction duct is shortened, the suction performance can be improved, a small blower can be used, the hopper has a simple closed structure, and the cost can be reduced. is there.

Also, since the suction cover is configured to be detachable, the cut grass can be left on the grass as in the related art if the suction cover is removed, and the suction cover is attached and housed in the hopper. The specification can be easily changed using the same machine and reel mower.

Further, an odd number of reel mowers are symmetrically arranged, and a pair of left and right two ducts are connected to the suction cover of the leading reel mower disposed at the center in the left and right direction to suck the reel mower. Although the suction force from is weak, it is sucked from two ducts, so the amount of work increases, so that the cut grass can be sucked in almost the same way as other reel mowers, and there is a difference in the cutting marks of multiple reel mowers And finish is beautiful.

A plurality of branching cones are connected to the suction port of the blower, and the amount of suction at each branching port is made proportional to the distance from the cone to the suction cover. The cut grass can be sucked by force, and the amount of the cut grass left undisturbed by the reel mower can be finished finely.
