PROBLEM TO BE SOLVED: To provide an agricultural machine in which a work history can accurately be found, even if a working area of a working unit is asymmetrical with respect to a center line extending in the longitudinal direction of a vehicle body.SOLUTION: An agricultural machine 1 includes a traveling direction detection unit 23 for detecting a traveling direction of a vehicle body 2. A traveling direction of the vehicle body 2 is added in addition to a position of the vehicle body 2 and a working area A of a boom nozzle device 10 by a spray history calculation unit 32, and thereby a range of the work performed is accurately calculated with a change of the position. According to the agricultural machine 1, a spray history H can accurately be found, even if the working area A of the boom nozzle device 10 is asymmetrical with respect to the center line L of the vehicle body 2. |
