20080264025 | Header height sensor apparatus for a header of an agricultural harvester - A plurality of elongate mounting brackets mounted in cantilever relation on a frame of a header at sidewardly spaced locations across at least a portion of a width of the header, respectively, support a sensor rod for rotation about its axis. Each of the brackets has a free end including a bearing having a bore therethrough which receives the sensor rod, at least some of the bearings being self-aligning bearings. The self-aligning capability enables accommodating irregularities in the mounting locations for the brackets, and also bends, flexure and other deformities of the header frame and sensor rod, for achieving free rotatability of the sensor rod. This mounting arrangement also facilitates installation by one person, from the bottom side of the header, both initially and in the field. Additionally, the brackets can include features for aligning the bores of the bearings, to facilitate the installation and free rotation of the sensor rod when installed. | 10-30-2008 |

20100077712 | HEADER GROUND SENSOR - The invention is a combination of a short ground sensor arm mounted close to the cutter bar and a longer rod mounted towards the rear of the header. The short front sensor and long rear sensor are connected by a linkage which translates motions from either sensor to the other sensor. A second linkage translates the motions of both sensors rearward to a protected area under the header which contains the potentiometer. This configuration transmits useful ground position signals to the header height controller in both low and high cutting heights. The invention advantageously reduces the likelihood of damage to the short front sensor when the machine is reversed since the longer rear sensor arm pulls the shorter forward sensor arm up by means of the linkage to a position where damage is unlikely. | 04-01-2010 |
