LAND GRADING APPARATUS OF GROUND AGRICULTURAL IMPLEMENT

摘要

PROBLEM TO BE SOLVED: To realize a land grading apparatus equipped with compact land graders for land grading of wheel ruts of a sulky rice transplanter.;SOLUTION: The land grading apparatus is composed by liftably and lowerably installing a seedling planting part 4 at the rear of a traveling car body 2, liftably and lowerably providing the land graders 33 and 33 in front of the seedling planting part 4 at the rear of rear wheels 6 and 6 of the traveling car body 2, composing the seedling planting part 4 so as to be stoppable at a midway position of a lowered land grading position and the topmost lifted position, keeping the seedling planting part 4 in a ground noncontact state and composing the land graders 33 and 33 so that they can be brought into contact with the ground by lowering movement thereof. The land graders 33 are not made to contact the ground even when the land graders 33 and 33 are lowered and moved. When the seedling planting part 4 is lifted to the midway position, the seedling planting part 4 is separated from the ground surface. When the land graders 33 and 33 are moved downward, only the land graders 33 and 33 can be brought into contact with the ground to eliminate the wheel ruts and carry out land grading.;COPYRIGHT: (C)2003,JPO
