A bale wrapper is a piece of farm equipment that is used for wrapping large square or round bales. Dairy farmers typically prefer wrapped bales as the plastic keeps the hay from spoiling. The wrapper has a loading harm, which is similar to a bale handler which scoops up the bale and sets it on the "wrapping table". The wrapping table has two rollers and four belts which spin the bale. As the bale turns the white plastic wrap or film is pulled through the dispensing unit, which tightly wraps the bale. This process is controlled by a small computer dives loaded in the cab of the tractor.
