PADDY FIELD WORKING MACHINE PROVIDED WITH FERTILIZING APPARATUS

摘要

PURPOSE:To prevent the damage of a fertilizer-feeding member at the time of lowering the member on a hard road surface by attaching a fertilizer-feeding member to a seedling-transplantation or direct-sowing working apparatus in a specific state, thereby minimizing the load of the working apparatus applied to the fertilizer-feeding member. CONSTITUTION:In the case of attaching a fertilizer-feeding member 11 to a working apparatus 2 in a state forced downward with an elastic mechanism A, the range of upper and lower moving limits is set in such a manner as to enable the movement of the lower end of the fertilizer-feeding member adjusted to the lowermost position to be higher than the lower face of a float 4.
