  • Patent number: 6062009
    Abstract: A two-row cane harvester 10 simultaneously harvests two rows of sugar cane in a green tropical cane field. A pair of topper mechanisms 54 top the cane stalks while base cutters 80 base cut the cane. Base cut cane is received base first into the harvester intake. The cane is cleaned in a whole stalk condition with a cleaning mechanism 92 that includes a plurality of rotating tines 100 moving in a direction to engage and force the cane leaves toward a base of the cane stalk, thereby efficiently stripping the cane leaves. An extractor blower 106 removes the leaves from the rotating tines and the cleaned cane. A stalk cutter mechanism 120, 122 may be adjusted to cut the cleaned cane stalks into selected billet lengths. Cane is preferably fed into the cutter mechanism at a speed greater than the ground speed of the harvester moving through the field. Another blower or fan may be used to remove remaining leaves from the billets.

  • Patent number: 6050069
    Abstract: A triangularly shaped frame having truncated and flattened vertices serves as a structural load-bearing member for an attachment to a yard tending device, such as a gas powered yard trimmer or leaf blower. A pair of support and maneuvering wheels is affixed to the frame. Affixed centrally to the frame, and rising generally vertically therefrom, is the first end portion of a lawn tending device support bar. At its first end portion, the support bar is of generally straight configuration. This straight portion serves to hold the lawn tending device at a sufficient elevation with respect to the ground. The straight portion of the support bar smoothly transitions to generally declining compound arcuate spanning portion. The spanning portion smoothly transitions to a generally declining straight second end portion. The second end is formed such that it comprises a cradle or channel running centrally and axially according to the length of the second end portion.

  • Patent number: 6050894
    Abstract: An impeller blade for the rotor of an axial flow combine harvester is shaped such that an outer blade portion has a shape of the blade portion defining an inclined edge which joins a forward blade edge lying in a radial plane of the rotor at a first position spaced outwardly from the hub of the rotor and joins the outer blade edge at a second position spaced rearwardly of the first position, the inclined edge having at least a part thereof which is substantially straight and parallel to an inner blade edge so as to be inclined at an angle to the outer blade edge and extend outwardly and rearwardly from the first position to the second position such that the radial distance of the second position from the axis is greater than that of the first position. This reduces the length of the forward edge to 50% to 75% of its conventional length and acts to overcome a long standing feeding problem of this type of rotor in some crops.

  • Patent number: 6047532
    Abstract: A crop harvesting header includes a wide cutter for severing crop across a relatively large cutting width, and framework defining a discharge opening spaced rearwardly from the cutter. The discharge opening has a width that is less than the cutting width such that crop severed laterally outboard of the discharge opening by the cutter must be conveyed inwardly before passing through the opening. At least one laterally extending, rotatable auger is located between the cutter and discharge opening for converging severed crop centrally from the areas located laterally outboard of the discharge opening and to project the crop through the opening when rotated. The header includes an auger support for rotatably supporting the auger between its opposite ends on the header framework so that the auger is capable of spanning the long distance corresponding to the large cutting width defined by the sickle bar.

  • Patent number: 6038794
    Abstract: A snow broom (10) includes a scraper element (12) and multiple sweeping elements (26, 36) positioned on opposite sides thereof. The scraper element (12) is in the preferred form of a sheet of relatively stiff plastic and includes serrations (22) formed on its lower edge (16). The lower edge (16) of the scraper element (12) is divided into a plurality of tines by cuts (24) extending from the lower edge (16). The inner sweeping elements (26) positioned adjacent to and on opposite sides of the scraper element (12) are formed from a sheet of foamed plastic of a flexibility to conform to the surface being swept and having a lower edge (30) parallel to and spaced slightly above the lower edge (16) of the scraper element (12). The outer sweeping elements (36) are formed from a sheet of extruded plastic to which snow does not have an affinity to stick. In addition to providing a sweeping function, the outer sweeping elements (36) provide protection and stiffening for the inner sweeping elements (26).

  • Patent number: 6039647
    Abstract: A grain sweeper mechanism having an auger supported in cantilevered fashion in front of a drive mechanism having a pair of wheels. A weight stack carried by the drive mechanism counterbalances the weight of the auger such that generally all weight is borne by the front drive wheel of the drive mechanism. The front drive wheel is operatively coupled with the outer end portion of the auger for receiving rotational power therefrom. An opening in a shroud of the auger extends generally the entire length of the auger. The drive mechanism is coupled with the auger shroud by way of an attaching mechanism which includes a slide member, channel member, threaded member and nut which allows vertical adjustment of the auger while hindering lateral movement of the drive mechanism with respect to the auger.

  • Patent number: 6032444
    Abstract: A non-row-sensitive forage harvesting header for attachment to a mobile frame carrying a chopper has a pair of rotatable cutting discs for severing stalks as the frame moves across a field. Positioned above the cutting discs are a pair of drum-shaped transfer devices rotatable in opposite directions about upright axes coaxial with the rotational axes of the respective cutting discs for gathering severed stalks to a central location between the devices. A pair of endless gripping elements extend about respective ones of the transfer devices and present opposed rearwardly moveable runs extending between the central location and the chopper when the header is attached to the frame. The opposed runs of the gripping elements are operable to cooperatively grip each gathered stalk therebetween while moving the stalk rearwardly from the central location to the chopper.

  • Patent number: 6032447
    Abstract: A detachable broom head is provided for quick and easy attachment to a lawn and garden rake. The broom head is adapted to be removably mounted on the rake such that a dual purpose lawn and garden tool is created. In one orientation the tool functions as an ordinary lawn and garden rake. In a second orientation the tool functions as a broom. Therefore, it is possible to use a single lawn and garden tool for tasks that require both raking and brooming. Additionally, the broom head may be attached to the rake so that the bristles of the broom do not interfere with the normal operation of the rake. In one embodiment, a pair of attachment clips are provided on the broom head to grip the rake frame. In another embodiment, a coupler is provided to attach the broom head to the rake.
