  • Patent number: 8544885
    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.

  • Patent number: 7578648
    Abstract: A work machine includes a frame and a front latch system carried by the frame at a front end of the work machine. The latch system includes a pair of laterally spaced, generally horizontally oriented slots, with each slot defined by an upper edge and a lower edge. The upper edge is longer than the lower edge and extends forward of the lower edge. A loader includes a pair of laterally spaced braces, with each brace having a distal end configured for contacting the ground when the loader is detached from the frame. A cross member coupled between the braces is received within the slots of the front latch system.

  • Patent number: 7281890
    Abstract: An arrangement for the attachment or detachment of a loader assembly or similar implement from a tractor includes a first member adapted to be received by a tractor, a second member adjustably connected to the first member, the second member adapted to receive the implement, and a third member also adapted to be received by the tractor, the third member mounted to the first member for movement between first and second positions relative to the tractor, movement of the third member from its first position into its second position causing transformation of the third member into an upright portion that assists in stabilization of the first and second members and the implement against the ground.

  • Patent number: 7168907
    Abstract: 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.

  • Patent number: 6647705
    Abstract: A rotary cutter has a deck assembly including a central unit to which a wing unit is attached for flexing vertically. A hydraulic cylinder is provided for lifting the wing unit 90° to a fully raised transport or shipping position. Located above, and extending generally parallel to, the hydraulic cylinder is a telescopic strut incorporating a spring which becomes compressed as the wing unit approaches its fully raised position, the compressed spring unloading to thrust the wing unit down upon pressure being released from the hydraulic cylinder, even if the weight of the wing unit is tending to keep it in its raised position. Wing unit may be locked in its raised position by inserting a pin through the telescoped members of the strut when the latter is in its fully collapsed condition.
