る。The mower decks 5, 6 are rotatably connected by their own weight on the inclined mower deck 6 side around the connecting pin 7, and the horizontal position V to the inclined A position with respect to the horizontal mower deck 5 are determined by a link mechanism or the like. An arrangement may be adopted in which an angle adjusting mechanism is provided so that it can be appropriately fixed at an angular position. The vehicle body 8 is made to travel along the ridge on the travel ground D. Mower deck 1 by extending and retracting lift cylinders 16 and 17
The horizontal mower deck 5 is guided along the ridge top surface B while determining the height 8 and the offset position. As a result, the inclined mower deck 6 assumes a posture along the ridge slope C. In this way, the blade grasses 3 and 4 in the mower decks 5 and 6 and the rotation of the lower blades 2 and 1 raise the levee grass,
It is cut short in two stages. For this reason, even if the plant height is long, it is hard to cut short, and it is hard to cause entanglement, it is possible to perform smooth cutting, and it is possible to reduce the uncut portion.

デッキ６においても同様の構成とする。4 and 5 are different from the above example in that:
An inclined mower deck 6 is arranged on both left and right sides of the horizontal mower deck 5 so that the ridge top surface B and the left and right ridge slope surfaces C can be simultaneously mowed. Work more efficiently. In FIG. 6, the point different from the above example is that the lower blades 2, 1 on the mower deck 5 are arranged at appropriate intervals L back and forth, and are driven for transmission, so that the upper blade 2 can cut a long grass earlier. By trimming the tip side and then cutting the root with the lower blade 1, each mowing action is performed accurately, and the mowing can be shortened and aligned. The same configuration applies to the inclined mower deck 6.

２＝Ｆ４の構成とするもよい。In FIG. 7, the difference from the above example is that the rotation diameter F1 of the upper blade 2 in the horizontal mower deck 5 is large and the rotation diameter F2 of the lower blade 1 is small. In addition, the rotation diameter F3 of the upper blade 2 of the inclined mower deck 6 is made small, and the rotation diameter F4 of the lower blade 1 is made large. At the time of cutting the ridge slope C, the rotation diameters of the upper blades 2 may be configured to intersect with each other, or the rotation diameters of the lower blades 1 may be configured to intersect with each other. . These lower blades 1 have the same rotational diameter F.
A configuration of 2 = F4 may be adopted.
