Many small and medium size round balers are equipped with a CATAGORY 3 CV PTO
Tractor connection is 1.375" x 6 spline or 1.375" x 21 spline quick disconnect
Baler connection is almost always 1.375" x 21 spline, except on John Deere models
Various clutches, shear bolt devices, and overrunning devices may be employed.
