A holder unit facilitates secure, safe and adjustableconnection between an agricultural implement and a draft vehiclesuch as a tractor. The holder unit mounts to the tongue of theimplement and engages a portion of a drivetrain, allowing thedrivetrain to rest on a saddle of the holder unit. The holderunit features three adjustability orientations, a fore-and-aftadjustability, a height adjustability and a saddle pivotadjustability. These adjustability orientations are easilycombined by the user to achieve accurate alignment forPTO-to-drivetrain connection irrespective of variations between thedraft vehicle and the implement drivetrain connector devicerespective orientations and terrain unevenness.
