An arm of a tractor-mounted loader is coupled to the top of a loader mast having a bottom end received in a pocket formed at an outboard area of a horizontal base plate of a loader mounting frame connected to one side of the tractor. A quick coupler support bracket is mounted to the base plate inboard of the pocket. Supported by and projecting upwardly from a horizontal fitting mounting plate of the support bracket are respective quick coupler halves forming ends of a first set of hoses that are coupled to the tractor hydraulic system. The first set of hoses extend through a hose passage, provided in a rear wall of a walled structure joined to and cooperating with the base plate so as to form a cavity therebeneath, and through a set of fitting openings provided in the fitting mounting plate. A second set of hoses extend from the rear of the arm and has a second set of quick coupler halves connected to the first set of quick coupler halves.
In a loader for a tractor having a longitudinally extending main frame, the loader comprising a loader mounting structure secured to the opposite sides of the tractor main frame and including a horizontal base plate extending outwardly from opposite sides of the tractor main frame, each base plate supporting coupling structure defining an upwardly opening pocket located outboard on the base plate from the tractor frame, an upright mast having a lower end releasably secured in each pocket, a loader arm pivotally attached to each mast, a boom cylinder coupled between each mast and each arm for swinging the latter vertically, an attachment pivotally mounted to forward ends of the arms, an attachment cylinder coupled between each arm and the attachment for pivoting the latter relative to the arms, and a first set of hydraulic hoses carried by one of the loader arms and having a first set of quick coupler halves at an end thereof coupled for receiving pressurized fluid from and returning exhaust fluid to the hydraulic system of the tractor, an improved hose mounting structure comprising:
