PROBLEM TO BE SOLVED: To readily and surely correspond to roll bales having various diameters in a series of motions of loading, wrapping and release of roll bales. SOLUTION: A control apparatus controls so as to detect a pressure of a hydraulic circuit 8 for carrying out each motion of a motion for transporting the roll bales R in held state over a field and a wrapping position carried out in loading and release of the roll bales R, a motion for carrying out retention of roll bales R and release of retention of roll bales R in a field and a wrapping position carried out in loading and release and a motion for wrapping roll bales at a wrapping position, and then changeover each motion when a detected pressure value is a prescribed pressure value.
