A plurality of annular collars are provided formed from collar halves. The collar halves are at least partially separable from one another to allow the collar halves to be slipped into and around a groove in a grooved roller for a reel-type cutting unit. The collar halves can then be abutted and secured together to substantially fill in the roller groove. When collars are placed into the last two or three grooves on each end of a grooved roller, a non-shouldered grooved roller is thereby converted into a shouldered grooved roller without having to remove and replace one set of rollers with another.
