適切に行うことができないのが実状である。By the way, not only ridges formed in the field but also straight ridges are formed, and some ridges are shallow, and there are many soft ridges of soil. In conventional agricultural work vehicles that are driven, wheels often ride on ridges or break ridges and do not travel correctly along the ridges.In order to keep the traveling direction of the agricultural work vehicle correct, workers need a high degree of skill. However, it has been pointed out that there is a need to frequently correct the traveling direction. Early cultivation of vegetables and the like covering the field scene with a black resin sheet is performed, but in the case of agricultural work in a field covered with a resin sheet, when returning the wheel riding on the ridge mountain to the ridge groove. In fact, there is a risk that the resin sheet may be strongly rubbed and damaged, so that the conventional agricultural work vehicle cannot perform such agricultural work properly.
