The Sur-Lock Quik-Tach System and the Quick-Hitch System (for John Deeres), both of which fit front-end loaders that have a double-cylinder hookup, allow the operator to change attachments quite easily. Once either system's latches have been manually set, hookup is automatic, so it does not require that one dismount from the tractor. Strong springs secure the latches when contact is made with the loader attachment.
