PTO adaptors allow you to connect a drive shaft or implement to a tractor PTO shaft where the spline size or type does not match. This is a common requirement when running older implements on newer tractors, or mixing equipment from different eras and manufacturers.

Spline sizes covered: 1 1/8" x 6 spline, 1 3/8" x 6 spline, 1 3/8" x 21 spline, 1 3/4" x 6 spline, and 1 3/4" x 20 spline. Adaptor types include quick-release, clamp-bolt, and standard push-on. Heavy-duty heat-treated versions are available for high-torque applications.
