<p>PROBLEM TO BE SOLVED: To provide a boom-type spray device capable of eliminating areas of double spraying and non-spraying area without performing a precise turning operation, and obtaining both high operation accuracy and high work efficiency.SOLUTION: A boom-type spray device 1 includes: a GPS receiver 10; an arithmetic processing unit 11 for performing arithmetic processing of a GPS signal and setting a position of a spray width end; and a spray width end position control unit 12 for variably controlling the position of the spray width end. The arithmetic processing unit 11 includes: sprayed area recording means 11a for recording a sprayed area to which spray treatment has been applied already; post-turning machine position recognizing means 11B for recognizing a machine position after turning by the GPS signal; and spray width end position setting means 11C for setting a position of the spray width end so that the sprayed area and a spray planned area do not overlap and a non-spraying area is not generated between the sprayed area and the spray planned area, on the basis of the sprayed area and the machine position after turning.</p> |
