The second feeding speed is higher than the first feeding speed to slope the plants rearward as they engage the feeding elements.

Abstract: A front harvesting attachment for a self-propelled harvesting machine having a central part pivotally mounted onto an intake channel of the harvesting machine, side parts that are moveable relative to the central part between an operating position, wherein the side parts are positioned on either side of the central part, and a raised transport position. Adjusting devices move the side parts between the operation and raised transport positions. Immobilizing devices selectively prevent movement of the front harvesting attachment relative to the intake channel during transport of the harvesting attachment. The immobilizing devices are coupled to the adjusting devices such that the immobilizing devices are actuated, thereby preventing movement of the front harvesting attachment relative to the intake channel, when the adjusting devices have moved the side parts to the raised transport position.

Abstract: A stalk roll for a harvesting device for harvesting crop heads of stalk-like plants. The stalk roll is provided with a roll body having projecting drivers distributed around its periphery. The pull-in speed of the stalk rolls in a picking region where the crop heads are removed is less than in a region of the stalk rolls situated farther downstream after the crop head has been removed. The diameter of the roll body in the picking region is greater than in the region situated farther downstream. In addition, it is proposed that upstream of a picking region the stalk roll have an inlet region which cooperates with the parts of the plants beneath the crop heads, where the pull-in speed of the stalk roll is greater than in the picking region.

Abstract: A combination of a harvesting machine, a crop picking head, and a vehicle to support the crop picking head. The vehicle features a mount and at least one wheel extending down from the mount that supports the crop picking head and alleviates the weight on the front wheels of the self-propelled harvesting machine when driving on the road. The vehicle is attached to the crop picking head when driving on the road and detached from the crop picking head when harvesting a field. The crop picking head includes a support frame which supports the harvesting equipment. In the preferred design, the mount is connected such that the support forces of the vehicle pass directly to the support frame rather than load more fragile components of the crop picking head.
