PROBLEM TO BE SOLVED: To improve stability against the right and left inclination of a dolly in traveling on the unleveled ground by providing a guide means for preventing falling from a ridge way and facilitating the adjustment of the right and left positions of the guide means and to facilitate maintenance including the replacement of tires. SOLUTION: With a push type spraying machine 1 in which a power sprayer 17 and a chemical tank 2 are installed on the dolly 16 having a front wheel 9 and a rear wheel 11, the front wheel 9 and a driving sprocket 53 arranged coaxially with the front wheel 9 are engaged by angular shafts. A support arm 33 supporting the rear wheel 11 is fitted horizontally slantably to a frame 8. The upper and lower positions of the rotational center of the inclination are arranged in places which approximately correspond to the shaft 30 of the rear wheel 11. Guide roller devices 22 arranged on both sides of the front wheel 9, right and left rotary arms 81 which support the guide roller devices 22 to be able to rotate vertically and horizontally, and adjustment shafts 88 which rotate the rotary arms 81 simultaneously and horizontally are provided.
