  • Rotary Disk Header with a Roller for Transferring the Crop Supported by a Center Bearing
    Publication number: 20140283493
    Abstract: A crop header has generally horizontal flail disks mounted on a cutter bar for driven rotation about generally upright axes. A pair of conditioner rolls is mounted in a discharge opening. A crop converging system includes two over-shot auger elements defined by a common rotary member with an auger flight carried thereon arranged generally longitudinal of the cutter bar so as to carry the cut crop longitudinally of the cutter bar to the entrance opening. The common rotary member includes two portions connected at a center location driven at one end and supported at the center location by a bearing and support plate connected to the cutter bar attached to one portion and a universal joint between the end of the supported portion and the other portion to allow flexing of the cutter bar to be transmitted though the universal joint.

  • Crop harvesting header with sealing member between draper and cutter bar
    Patent number: 8769919
    Abstract: A crop harvesting header with a cutter bar and a draper assembly has a draper which includes a front edge of the upper run of the draper arranged at a position adjacent to but spaced from the cutter bar and there is provided a sealing member extending along the cutter bar. The sealing member is co-extruded to form a constant cross-sectional shape along the full length and to define a first portion of a stiffer plastics material attached to the cutter bar and a second blade portion of a more flexible plastics material which extends rearwardly from the first portion at the cutter bar to lie over and in contact with a bead along a front edge portion of the draper.

  • Header transport for a crop harvesting machine
    Patent number: 8769920
    Abstract: A hydraulically driven swather tractor can move in a cab forward orientation in a working mode with a header on the forward end and can be rotated to engine forward in the transport position for more stable higher speed travel. A system is provided for transferring the header from field to transport position automatically from the cab and includes an arm which permanently connects to the header from the tractor independently of the lift and float mounting system such that in the working position the arm remains connected to the tractor and the header while allowing movement of the header relative to the tractor. Also in the transport position, with the header disconnected from the mounting system, the arm extends from the tractor to the mounting system of the header for supporting the forward end of the header for towing the header longitudinally.

  • Draper support of a crop harvesting header
    Patent number: 8752359
    Abstract: A crop harvesting header with a cutter bar and a draper assembly has a draper driven by a drive roller at one end and an idler roller at the other end. The draper is carried on a plurality of support rollers parallel to the first and second rollers for supporting the upper run of the draper at spaced positions therealong. The draper includes a front edge of the upper run of the draper arranged at a position adjacent to but spaced from the cutter bar and there is provided an integral extruded sealing member extending along the cutter bar defining a first stiffer portion attached to the cutter bar and a second flexible blade portion which extends rearwardly from the first portion at the cutter bar to lie over and in contact with a bead along a front edge portion of the draper.

  • Swather with float assembly and disconnect coupling
    Patent number: 8745964
    Abstract: A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. There is provided a float module with adjustable and calibrated springs on the header which allows the header to float relative to the lift system on the tractor. The float force is adjusted by raising and lowering the lift system in dependence on an angle measurement of the lift position. The lift system includes a lift cylinder and tilt cylinder controlled to change cutter angle while maintaining a sight line to the cutter bar for the operator.

  • Roller with raised elements clad on the surface for driving a crop conveying belt
    Patent number: 8662132
    Abstract: A drive roller for a crop conveying belt has a cylindrical roller body having an outer surface surrounding an axis of rotation of the roller for engaging an inner drive surface of a canvas wrapped therearound. The roller has a plurality of raised spaced elements such as ribs formed of a hard wear resistant material such as carbide clad onto the outer surface metal of the roller body. The ribs extend along a part only of the body at the two ends in an axial direction and angularly spaced around the outer surface. The ribs have a height less than 6 mm and a width less than 6 mm arranged such that the ribs do not engage into any recesses in the drive surface of the belt.
