Abstract: A loader mast-to-mounting frame pin arrangement is provided. The pin arrangement has stops added to a shaft that allow the pin to be held in two positions: the locked position and the parked position. In the locked position, a unique slot cut in the mast plate retains the pin by not allowing an eccentric protrusion on the shaft from passing through the slot when the pin is rotated to place the shaft in the top of the slot. When the pin is rotated so the shaft is towards the bottom of the slot, the eccentric protrusion is allowed to pass through the mast plate and the pin can be pulled out until it hits another protrusion on the shaft. At this point, the pin will stay in the mast but the loader can be removed from the tractor. To prevent the pin from rotating by itself, when in the locked position, and the loader coming unlatched, a spring loaded knob engages in the slot which prevents the shaft from being able to rotate to the unlocked position.

Abstract: A parking stand arrangement for a tractor-mounted front loader includes a parking stand mounted to each of a pair of arm sections which are inclined downwardly and forwardly to a carried implement resting on the ground. Each parking stand includes a support leg and a brace, the latter being about half the length of the former and having a rear end pivotally mounted to a location approximately halfway between opposite ends of the support leg and an forward end pivotally mounted to a lower region of an associated loader arm section. The support leg and brace may be stored on the loader arm section by folding them together with a catch carried by the brace becoming releasably engaged with the support leg. The folded support leg and brace are then pivoted against the loader arm section and secured to it by a releasable latch which secures the top of the support leg to the arm section to establish a stored position.

Abstract: A directional bushing is provided for a pinned joint of an articulated structure such as a front end loader used with a work vehicle. The bushing has an annular ring portion and an oblong flange portion. The flange portion extends angularly outward from one side of the ring portion so as to form a wider rounded end. The flange portion is thicker at the area adjacent to the ring portion so as to provide additional support to the ring portion under load, and tapers to a more thin profile at the rounded end. The bushing is surface welded to the structure at the pinned joint with the flange portion oriented in the direction of the greatest load when the structure is articulated, so that the load is more evenly distributed over a wider area, thereby preventing weld failure.
