A method and apparatus for using a round baler of a type which forms a windrowed crop (19) into a round bale (17) in a bale forming chamber, and has knives (20) for cutting the crop prior to when the windrow (19) of crop enters the bale forming chamber. The knives (20) are movable between a cutting position and a non-cutting position. The size of the bale (17) is sensed as it is being formed and the knives (20) are moved to the non-cutting position as the bale (17) is being started in the bale-forming chamber. After the bale (17) has been started, the knives (20) are moved to the cutting position and these knives (20) remain in the cutting position unless the shape of the bale becomes irregular. When the bale (17) is nearly to its completed desired final size, the knives (20) are moved to the non-cutting position until the bale (17) is completed so that the outside of the bale (17) will hold together better than if such outside portion is cut as the windrow (19) is added to the bale (17). |
