| 20120107080 | Loader Mast-To-Mounting_Frame Pin Retaining Arrangement - 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. To operate, the knob is pulled back away from the mast and then the shaft can be rotated. | 05-03-2012 |
