Patent number: 7168907Abstract: The masts of a front-end loader are releasably attached to vertical plates of a loader mounting frame located at the opposite sides of a tractor by latch hooks pivotally mounted to the masts and engaged with latching elements carried by the vertical plates. An over center biasing arrangement acts on each latch hook and acts to bias the latch hook to a closed position, but moves over center when the latch is manually opened so as to bias the latch to its open position. The pins pivotally coupling the latches to the masts also serve to couple the piston rods of a pair of loader boom lift cylinders to the masts. Extension of the cylinders during detaching the masts from the vertical plates causes the opened latch hooks to be pivoted to the extent that the biasing elements move over center and reset the latches to their closed positions, which positions are conducive for automatically reattaching the mast to the vertical plates.Type: GrantFiled: May 2, 2005Date of Patent: January 30, 2007Assignee: Deere & CompanyInventors: Russell George Lyons, Radu Traian Guja

Patent number: 6220365Abstract: A method of and apparatus for transporting farm implement sideways, on narrow passageways. The apparatus comprising a hitch assembly, carrier assembly, trailer assembly, and a turret assembly. The farm implement is attached to the turret assembly, which allows the implement to be rotated ninety degrees via the turret. To move the farm implement the trailer assembly is extended downward lifting the implement up from the ground, the implement is then rotated so that it aligns parallel to the carrier assembly. The turret assembly is then locked in position for transport. In the field the turret assembly is unlocked and rotated ninety degrees, the trailer assembly is raised, which lowers the implement to the ground. The apparatus is connected to a farm tractor's three point hitch, hydraulic system and power takeoff. The three point hitch raises the apparatus hitch and tongue during transport and lowers the hitch and tongue during field work.Type: GrantFiled: September 10, 1998Date of Patent: April 24, 2001Inventor: Jerry R.

Patent number: 5738176Abstract: A battery-powered grass mower (12) is hitched to en electric garden tractor (10). The hitching system has arms (27) pivoted (29) to the tractor, which can be raised and lowered by means of ah electric actuator strut (45). To hitch, the tractor is maneuvered until pegs (30) pivoted on the arms are poised above sockets (20) on the mower; then, using the electric actuator, the arms are lowered, driving the pegs into the sockets. Once firmly engaged, a latch (36) engages and retains the pegs into the sockets. The latch is releasable electrically. All aspects of hitching and unhitching are under remote control from the driver's seat.Type: GrantFiled: September 20, 1995Date of Patent: April 14, 1998Inventor: Newton Roy Gingerich

Patent number: 5540289Abstract: A stand apparatus for a front loader having masts attachable to mast mounts of a tractor through pivotal supports and mast fixing members, booms connected to the masts, boom cylinders and braces. The stand apparatus includes stand members each defining a slot for receiving a pivotal support disposed in a lower position on each mast, and a stand locking bore formed adjacent thereto. Each stand member is pivotable between an operative position in which a ground engaging end thereof contacts the ground to stand the front loader, and a contained position in which the ground engaging end is supported by the front loader. The pivotal support of each mast is movable in the slot to limit an amount of upward projection of the stand member in the confined position.Type: GrantFiled: November 30, 1994Date of Patent: July 30, 1996Assignee: Kubota CorporationInventors: Masami Hirooka, Kazuhiko Ikeuchi, Toshihiko Waka
