Description
Splined Yoke 01 (Push Pin) — Quick-Release Splined PTO End Yoke for Tractor Connections
The Splined Yoke 01-Push Pin is a standard tractor-end PTO connection yoke with a 1 3/8-inch, 6-spline (Z6) internal bore that mates directly with the tractor PTO output stub shaft. The integrated spring-loaded push pin provides positive locking for fast, tool-free attachment and detachment — saving valuable time when switching between implements during busy seasons. Precision-forged and CNC-machined from alloy steel, this yoke features hardened spline teeth and bearing bores for thousands of hours of service.
