<P>PROBLEM TO BE SOLVED: To provide a working vehicle having improved work efficiency of a topping work of crop and giving reduced load on a worker. <P>SOLUTION: The working vehicle is provided with traveling devices 3, 4 and, on the traveling devices 3, 4, a driver's seat 5, a chemical storage part 6 for storing a chemical to be sprayed on the crops, a spray boom 140 to spray the chemical in the chemical storage part 6 to the crops, and a cutting blade device 30 furnished with a cutting blade 27 for cutting the top of the crop. Since the topping work can be performed without removing the spray boom 140, preparation before the work becomes unnecessary, the load on the worker is reduced, and the topping work can be quickly started. Since the topping work and the chemical spraying work can be performed at the same time, the work frequency can be reduced and the work efficiency of the topping work and the chemical spraying work can be improved to reduce energy consumption compared with the case to separately perform the topping work and the chemical spraying work. <P>COPYRIGHT: (C)2012,JPO&INPIT |
