- a rotary cutter bed extending across the front of the harvester and having a series of rotary cutters rotatable about individual, upright axes,
- said series of cutters including a group of inboard cutters each having an axis of rotation located inboard of the opposite ends of said conditioning structure and at least one outboard cutter located outboard of each end of the group of inboard cutters,
- said outboard cutters having axes of rotation located outboard of the opposite ends of said conditioning structure,
- each of the first and last inboard cutters in the group and the next adjacent one outboard cutter rotating in mutually opposite directions,
- the first and last inboard cutters in the group each having a cutting blade that projects laterally outwardly beyond the corresponding end of said conditioning structure as the cutting blade sweeps rearwardly;
- and
