LAND GRADING FLOAT FOR PADDY FIELD WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a land grading float by which the attitude disorder or fall of transplanted seedlings is reduced, planting defect is suppressed and working accuracy is improved by forming a downward protruding part on the lower surface of central part for preparing land at a central position among scheduled planting positions. ;SOLUTION: In this land grading float 13 for paddy field working machine for grading the land at the scheduled seedling planting positions for three lines while sliding on muddy surface, a downward protruding part 13a is formed on the lower surface of central part 13A for grading the land at the central position among the scheduled planting positions. In this case, it is preferable that the central part 13A is protruded forward rather than a side part 13B for grading the land on both the sides of scheduled planting positions and muddy soil dam instruments are arranged on left and right sides for preventing muddy soil from flowing out to left and right outsides by being pressed with a forepart with sliding on the muddy surface.;COPYRIGHT: (C)1998,JPO
