Engage the tractor engine, and slightly raise the hydraulic hitch by pressing the control lever forward.
Back up the tractor toward the attachment of choice, aligning its three-point hitch with the hitch connector on the attachment.
Engage the hydraulic lift lever to raise the hitch -- just high enough to catch the connector on the attachment.
Secure the two latches, found on each side of the hitch connection, to lock the attachment to the tractor.
Connect any pneumatics, if applicable, by rotating the handle on the attachment end of the hitch connection so the pneumatic cable connectors line up. Face forward again, toward the tractor controls, and pull the "AutoHitch" lever to power the connection.
