Abstract
A mechanical system attaches to a tractor and, upon activation of a hydraulic ram, rotates implement-engaging implement lift hooks to rotate an attached agricultural implement upwards towards 90 degrees for inspection and maintenance. The system can be secured in its raised and rotated position via a locking pin. The implement is returned to its original position through removal of the locking pin, reversal of the hydraulic ram and disconnection of the implement lift hooks.
