The PTO Link™ Compact system (for tractors up to 40) 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.
