Patent number: 9587370Abstract: A tractor-mounted front loader includes a parking stand mounted to each of a pair of downwardly and forwardly inclined arm sections coupled to an implement resting on the ground. Each parking stand includes a support leg and a brace, the latter 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.Type: GrantFiled: July 15, 2013Date of Patent: March 7, 2017Assignee: Deere & CompanyInventors: Henry A Lanting, Scott R Jamieson, Radu T Guja, Henry Friesen

Patent number: 9234327Abstract: A front loader arrangement includes a bracket, a mounting mast mounted on upper and lower bearings of the bracket, a loader arm which is articulated to a first pivot pin on the mast, a loader support articulated to a second pivot pin on the mast, and a locking device for locking the mast to the bracket. The locking device is arranged on the loader support. The locking device includes a pivoting locking bar which is mounted on a third pivot pin on the loader support, a pre-tensioning device which pre-tensions the locking bar depending on its position relative to the loader support into an open or a closed position, and an adjusting device arranged on the mast which can be brought into engagement with the locking bar, by which the locking bar can be moved into the closed position.Type: GrantFiled: July 24, 2014Date of Patent: January 12, 2016Assignee: DEERE & COMPANYInventors: Jody A. Oickle, Henry Friesen, Radu T. Guja

Patent number: 8777546Abstract: A carrier is provided for releasably attaching a tool to the lift arms of a work machine. The carrier comprises a lift arm attachment point for attachment to the lift arm, a tool attachment point for releasable attachment of the tool to the carrier, and a contact pad, for contacting the tool in use. In use, the lift arm and contact pad lie in the same vertical plane. Providing a contact pad between the carrier and tool in line with the lift arm removes any transverse bending forces on the carrier.Type: GrantFiled: March 5, 2010Date of Patent: July 15, 2014Assignee: Deere & CompanyInventors: Henry A. Lanting, Scott R. Jamieson, Radu T. Guja

Patent number: 8549775Abstract: A remotely operable latching system for securing an implement to a carrier mounted to a forward end of a lifting arm for pivoting about a horizontal tilt axis. The latching system is mounted to the carrier and includes a latching rod arrangement operated by an extensible and retractable linear electric motor between a retracted latching position and an extended unlatching position. A secondary latch arrangement is provided for rotating the latching rod arrangement to an arrested position preventing movement of the rod arrangement to its latching position once the latching rod is extended to its unlatching position. Movement of the rod arrangement to its arrested position is aided by a spring and by the electric motor. A microprocessor based control unit is coupled to the electric motor and acts in response to a boom height input signals to prevent operation of the motor when the boom is above a preset height.Type: GrantFiled: January 24, 2011Date of Patent: October 8, 2013Assignee: Deere & CompanyInventors: Henry A.

Patent number: 8500386Abstract: A front-mounted loader includes a pair of loader arms each having a rear end pivotally coupled to a loader mast which, in turn, includes lower and upper cross pins respectively located in an upwardly opening and forwardly opening pin receptacles. The forwardly opening receptacle of each loader mounting frame forms a fixed part of a latch assembly defining an upper region of the mounting frame and including latch member mounted for pivoting about a horizontal axis and having a forward nose provided with a downwardly opening receptacle which engages the upper cross pin when the mast is latched to the mounting frame. An over center biasing spring is connected to each latch member and resists movement either from a latching position or an unlatching position.Type: GrantFiled: April 26, 2010Date of Patent: August 6, 2013Assignee: Deere & CompanyInventors: Stephen Griffiths, Radu T. Guja

Movement of the rod arrangement to its arrested position is aided by a spring and by the electric motor. Release of the rod arrangement from the arrested position is done by rolling the carrier back towards the lifting arms bringing the latching rod arrangement into contact with the arm so as to pivot the rod arrangement out of its arrested position.Type: ApplicationFiled: January 24, 2011Publication date: July 26, 2012Inventors: Henry A Lanting, Radu T.
