  • Patent number: 8544246
    Abstract: A wing lawn mower for cutting grass is herein described. The wing lawn mower is attached to a main mower, the wing mower moveable from a lowered position to a raised position. When in the lowered position, the wing mower is driven by a wing belt, which is in turn driven by a main mower deck pulley. When the wing mower is moved to the raised position, the wing belt becomes slack. The slack causes the wing mower blades to cease turning. Then the wing mower is lowered into the cutting position, the wing belt pulled taught. When this occurs, the wing belt is guided back into place against the wing pulley by belt retainers. This allows the wing mower to be raised and lowered without having to remove or reconfigure the wing belt.

  • Patent number: 8006469
    Abstract: A crop header has generally horizontal flail disks mounted for driven rotation about generally upright axes. A pair of conditioner rolls is mounted in a discharge opening and a transfer roller is mounted behind the disks and in front of the nip. At each end, two disks are mounted outwardly of the discharge opening each rotating so that its blade moves inwardly and each carries an impeller to carry the crop inwardly. A third disk is arranged so that a line forward of the end of the discharge opening intersects the third disk inward of the axis of the third disk. The third disk rotates so that its blade moves outwardly so that the crop tends to pass between the second and third disks. A pair of impellers are mounted behind the second disk and move inwardly to carry the cut crop to the discharge opening.

  • Publication number: 20110173940
    Abstract: A movable frame for connection to a prime mover that supports multiple individual similar implements in a manner similar to the manner each would be singly connected in a trail-behind implement pulled by a prime mover, but maintains relative positioning between the implements sufficiently to enable the multiple implements to function as a single, larger implement. The frame allows individual implements to be positioned generally transversely in an operating position for travel in a first direction providing maximum operating width, and generally longitudinally in a transport position for travel in a direction opposite to the first direction in which the overall with of the implements on the frame is minimized to three meters or less.

  • Patent number: 7973654
    Abstract: A system and method for detecting impending failure of a component of a disc cutterhead of a cutterbar of a plant cutting machine, the components will generate at least one indicator of an impending failure thereof, utilizing a plurality of sensors distributed among the cutterheads, each of the sensors being configured and operable for sensing at least one of the indicators of impending failure and outputting signals representative thereof to a controller automatically operable for processing the signals, to enable identifying an individual location or one of the cutterheads in which an impending failure of one or more of the components is present, and outputting a signal representative thereof to a warning device. The indicators can include, but are not limited to, temperature, sound, and vibration. The controller is also operable for determining comparative threshold values for the indicators, to adapt to changing conditions and norms.

  • Patent number: 7971415
    Abstract: A grass mowing machine has a frame with an adjustable width toolbar including a center section and left and right outer sections telescoping into the center section. A pair of cutting units are mounted to lift arms pivotably connected to outboard ends of the outer sections of the adjustable width toolbar. A hydraulic lift cylinder is mounted between an inboard end of each lift arm and the adjustable width toolbar at a selected mounting point in the center section. The mounting point of the center section is aligned with a mounting point in one of the outer sections to provide a specified toolbar width suitable for the cutting units.

  • Patent number: 7793487
    Abstract: A gang-type lawn mower system comprises a main frame or frame structure and a plurality of mower decks secured to the main frame. Mounted on the main frame is a power source such as an internal combustion engine. A drive train is interconnected between the power source and each of the mower decks. Thus, each mower deck is driven by the single power source. Further, the frame structure includes a tongue that is adapted to be connected to a tractor. Therefore, in cutting grass, the frame structure is pulled over the ground and each of the mower decks, driven by the power source, cuts grass or other vegetation that passes under the mower decks. Additionally, each mower deck is pivotally connected to the frame structure about at least one pivot axis.

  • Patent number: 7716904
    Abstract: A cutterbar drive mechanism cover for use in a specialty crop harvesting header to optimally direct severed crop material from the cutterbar to a crop conveying apparatus which then laterally converges the crop material from outboard ends of the cutting header toward an interior discharge zone for formation of a windrow or for further processing. Crop flow smoothing by the drive cover also reduces disturbances to the crop material during movement within the header which reduces seed loss in seed-bearing specialty crops.
