ABSTRACT:
Front end loader mounting structure including a rear support assembly for receiving pivot tubes located at the lower ends of the rear upright mast posts. A round cross tube connecting the forward ends of the mast arms is rotatable upwardly through an arc-shaped path with center of radius of the path located on the axis of the pivot tubes. The cross tube is received within an inverted cradle assembly located directly in the path and is releasably locked in a raised mounted position within the cradle assembly by latching structure remotely actuated from the tractor cab. The mast posts include downwardly extending projections which are freely received by the support assembly when the loader is in the stored position but which rotate against a locking block to secure the posts tightly to the tractor frame as the mast arms approach the upwardly rotated position.
