  • Patent number: 8684656
    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.

  • Patent number: 5165836
    Abstract: An apparatus for lifting and transporting one or more large bales of material, comprising a trailer to be towed by a towing device and hydraulically powered by an outside source, preferably incorporated in the towing vehicle. The apparatus has tines adapted to fit beneath a bale and cradle and lift the bale in the manner of a fork lift, which is done by exerting force downwards on the wheels of the trailer, thus lifting the frame and attached tines. Connection to the towing device's three-point hitch also affords a lifting device. A device may be provided for shifting the trailer between a transport position, where the trailer is generally aligned behind the towing device, and a working position where the trailer is aligned outwardly and behind the towing device. The tines are positioned generally horizontally and substantially parallel with the longitudinal axis of the trailer. Bales are lifted by the apparatus off the ground for transportation.

  • Patent number: 4915575
    Abstract: A material handling attachment such as a bucket or the like is pivotally secured to the three-point hitch assembly of the tractor. The hitch assembly is movable between a lower position and an upper position by means of standard equipment on the tractor. A mechanical linkage interconnects the bucket, hitch assembly and the tractor so that the bucket will be in a substantially level position when the hitch assembly is in its lowermost position. As the hitch assembly is moved upwardly relative to the tractor, the linkage maintains the bucket in a level position. When the hitch assembly reaches its uppermost position, the linkage causes the bucket to be moved to a dumping position. After the material in the bucket has been dumped therefrom, the three-point hitch assembly is lowered with the bucket being automatically re-set to its operative or working position.
