PROBLEM TO BE SOLVED: To solve the problems of a conventional air-jet fertilizer applicator comprising the necessity to the separate installation of a compressed air generation apparatus such as a blower to increase the production cost and lower the assembling easiness and maintainability of the fertilizer applicator and the problems comprising the increase of energy consumption in a driving engine or motor to meet the requirement of a considerable quantity of compressed air for the transfer of fertilizer resulting in the increase of the operation cost such as fuel cost of the applicator. SOLUTION: The fertilizer applicator is provided with a supplying mechanism 10 to supply cooling air passed through a water-cooled radiator 47 of an engine 2 as compressed air. The supplying mechanism 10 has the radiator 47 and a blower 48 to send the cooling air to the radiator 47. The radiator 47 is placed at the intake-side of the blower 48 and the exhaustion port 48b of the blower 48 is connected to a transfer pipe 39. COPYRIGHT: (C)2007,JPO&INPIT
