The PTO Link™ HD system (for tractors 35 HP to 130 HP) is designed to quickly and safely connect/disconnect tractors and implements at the PTO… in seconds! The PTO Link™ is the original, universal quick-connect system that consists of two interconnecting plates (female and male). For best results, every tractor should have the Tractor (Female) Plate installed and every implement should have an Implement (Male) Plate installed.
