PTO Link® HD System – Duo Bundle (1 Tractor & 1 Implement Coupler)


The PTO Link HD System is designed for compact or utility tractors rated from 35 HP up to 130 HP (engine net) and with most 3-point hitch or pull-behind implements. PTO Link® is the original, universal PTO quick-connect system consisting of two interconnecting steel couplers. Its patented Open-Plate™ design replaces the traditional spline-to-driveline connection with a visible interface 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 and information below.
