This invention reveals a corn harvester header comprising: multiple harvesting units placed adjacently among them, where each of said harvesting units has a central slot through where a maize plant is processed to separate the ears from the stalks; multiple crop divisors, each placed between two adjacent harvesting units; and multiple frontal devices, each place in front of and between two adjacent harvesting units; where each one of said multiple frontal devices comprise: a pair of guiding elements, where the guiding element is selected from a group of: chain or belt; two or more wheels; and a support; where the guiding element is placed around said two or more wheels; where one of the two or more wheels drives the spin of the guiding element, where the tangential speed of the guiding element is configured according to the distance between the plants in the crop; and where an opening greater that the harvesting slot is created.

A stalk roller assembly for an agricultural system includes a stalk roller having a hollow shaft. The hollow shaft has a first end having a first shape, such that the first end engages a guide element. Furthermore, the hollow shaft has a second end having a second shape that engages a drive shaft, such that the first shape is different than the second shape. In addition, the hollow shaft is formed from a single piece of material.

In a harvesting machine having an agricultural header which is adjustable in height, a computer controller includes programming instructions to allow an operator to associate a plurality of different harvester functions with a single programmable input button providing single-touch actuation. The input button is programmable to return the header height to a preset height value in addition to controlling position of one or more additional accessories such as a double windrow attachment, a deck shifting set of drapers of the header, and/or a crop compressor attachment, etc. Programming of the input button uses navigational inputs to select which functions of the machine are associated with the button, followed by a press-and-hold actuation to set the preset value of all associated functions based on the current operating condition.

An agricultural header includes: a header frame; at least one cutting unit carried by the header frame and including a cutting element and a driveshaft coupled to the cutting element; and a gearbox configured to drive the cutting element. The gearbox includes a gearbox output rotatably coupled to the driveshaft; and a clutch including an intermediate shaft and at least one clutch shoe rotatably coupled to the intermediate shaft and displaceable between a non-engaging position where the at least one clutch shoe does not engage the gearbox output and an engaging position where the at least one clutch shoe engages the gearbox output. The clutch is configured such that the at least one clutch shoe displaces to the engaging position when a rotational speed of the intermediate shaft reaches a threshold value.

A detasseling apparatus includes a chassis having a head mounted to the chassis. The head supports a plurality of row units, each of the row units having an independently adjustable vertical position. Each row unit is independently vertically adjustable. Each row unit includes a puller or cutter, a height adjustment assembly for independently adjusting vertical position of the detasseling assembly to maintain the puller or cutter at a predetermined height relative to seed corn plants being engaged, and an optical sensing assembly. The optical sensing assembly includes a first photoelectric sensor at a first sensor height and a second photoelectric sensor at a second sensor height, the first sensor height being above the second sensor height. A processor receives and stores detasseling data related to detasseling including corn height, depth of cut, height after cutting. The information may be shown on displays to the operator, stored on board the detasseler and/or transmitted to a central control center.

When using a cross auger assembly on a crop harvesting header with a flexible frame having end frame sections pivotal relative to a centre frame section, mounting devices are coupled between the bearing housings at opposing ends of the cross auger assembly and the outer ends of the end frame sections. Each mounting device includes a first mounting structure fixed relative to the outer end of the end frame section, a second mounting structure fixed to a portion of the respective bearing housing, and a flexible mounting arrangement between the mounting structures to accommodate variation in lateral positioning of the bearing housings relative to the ends of the flexible frame as the flexible frame flexes over varying ground contours without requiring a telescoping shaft arrangement on the cross auger assembly.
