20090056296 | HEADER TRANSPORT - A swather tractor has ground drive wheels at a first end, castor wheels at a second end and a header lift arms at the first end and can be driven with the first end forward for harvesting and with the first end rearward for towing. A transport for the header includes a longitudinal beam with a plurality of transverse support arms along the beam. The beam is kinked adjacent the front so that a main portion of the beam is offset to one side relative to the hitch assembly and the rear wheels. A yoke engages the lift arms and provides a hitch for towing the header. Either the forward end of the beam is directly attached to the hitch for small headers or for larger headers a steerable front wheel assembly is connected to the hitch and includes a spring coupling which transfers load to the lift arms. | 03-05-2009 |
20090107099 | CROP FEED ARRANGEMENT FOR THE HEADER OF A COMBINE HARVESTER - A draper header for a combine harvester includes two side drapers each running from an outer end guide roller at a first end of the header to an inner end guide roller adjacent the discharge location of the header and a central feed draper located at the discharge location and including a front guide roller just behind the cutter bar and running to a rear guide roller in front of the feeder house of the combine harvester. An auger is located between the discharge rollers with a front edge of the flight forward of the rear end of the discharge rollers to feed the material inwardly and underneath the auger to the inlet of the feeder house. A pan member is located underneath the feed draper and is formed of a flexible polyethylene sheet which is tensioned between its front and rear edges by a front mounting strip which is spring mounted for up and down movement and a rear latch which can be released to allow the rear edge to be lowered. | 04-30-2009 |
20130125521 | Crop Harvesting Machine with Header - 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. | 05-23-2013 |
20130305674 | Crop Harvesting Machine with Calibration of the Header Float Springs - 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. | 11-21-2013 |
20130305676 | Swather with Float Assembly - 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. | 11-21-2013 |
20130305677 | Header Transport for a Crop Harvesting Machine - 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. | 11-21-2013 |
20130333343 | Swather with Floating Header - 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. | 12-19-2013 |
20140150391 | Rotary Crop Harvesting Machine with Cutter Bar Tilt Control - A crop header has generally horizontal flail disks mounted for driven rotation about generally upright axes of a cutter bar. A tilting system is provided for tilting the cutter bar about an axis transverse to the machine so as to tilt the cutting plane from a generally horizontal position forwardly and rearwardly. A sensor is provided which is responsive to upward and downward floating movement of the cutter bar relative to the support frame and is arranged to analyze changes in the signal to determine times when the cutter bar is moving upwardly when the cutter bar is tilted rearwardly, times when the cutter bar is moving downwardly when the cutter bar is tilted forwardly and times when the cutter bar is remaining at a constant height. | 06-05-2014 |
