PROBLEM TO BE SOLVED: To obtain a crawler sprayer simplified in structure and capable of easily synchronizing the pay out and wind-up of a hose with the travel speed of the crawler sprayer by rotating a hose reel from sprockets for driving the hose reel engaged with a specific position through a transmission mechanism. SOLUTION: In this crawler sprayer, sprockets 17 for driving a hose reel are engaged with a sprocket-engaging member 9 for driving a crawler on the inner side surface of the travel crawler 8, and the hose reel 7 is rotated using the hose reel-driving sprockets 17 through transmission mechanism 18-27. Preferably, in the crawler sprayer, the sprockets 17 for driving the hose reel are engaged with the sprocket-engaging member 9 for driving the crawler on the inner side surface of the travel crawler 8, and the hose reel 7 and a regularly hose-winding means 29 interlocked with the hose reel 7 are driven using the hose reel-driving sprockets 17 through the transmission mechanisms 18-27.
