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 |
