PTO Link® SD System

The PTO Link® SD System is our original model.  It’s designed for medium duty applications with most* compact or utility tractors rated up to 100 HP (engine net) with most three-point hitch implements (Category 1 or 2). For applications involving drawbar implements, see the HD System. *See tractor model exceptions below that MUST use the Compact System

All PTO Link® Systems add up to 5 inches to the implement’s PTO driveline.  Always measure and adjust driveline length as needed.  

PTO Link® is the original, universal PTO quick-connect system consisting of two interconnecting steel couplers. Its patented Open-Plate system replaces the traditional spline-to-driveline connection with a visible interface design that’s both easy to see and reach. Now you can quickly and safely connect / disconnect implements at the tractor’s PTO in just seconds! A complete PTO Link® System requires both a Tractor (Female) Coupler and an Implement (Male) Coupler. For best results, every tractor should be equipped with a Tractor Coupler, and every power-driven implement should be equipped with an Implement Coupler. See more descriptions, product features and safety information below.
