PROBLEM TO BE SOLVED: To enable a film to be quickly wrapped around a roll bale by preventing vibration caused by centrifugal force.SOLUTION: A wrapping machine 1 is provided which includes: tires 3 capable of traveling on a farm field a frame to be supported by the tires 3 and a wrapping mechanism 5 for wrapping a film 53 while relatively rotating a roll bale 9 and the film 53 on the frame 2. In the machine, a first ground-contacting member 71 and a second ground-contacting member 75 are provided so as to separate the tires 3 from a ground when wrapping the film 53. When separating the tire 3 in this way, the tire 3 is separated from the ground by: moving the first ground-contacting member 71 at the rear of the tire 3 downward after moving a front side of the frame 2 downward and after that, moving the second ground-contacting member 75 on the front side of the frame 2 downward by using a lower link 8 of a tractor to move the front side of the frame 2 upward.
