Abstract

A system, and the method of operation and use thereof, for controlling and adjusting the height of a base cutter of a sugar cane harvester, during a harvesting operation, and without the necessity for continuous user intervention and adjustment, to maintain the height of the cut at approximately a desired height, including a control system that has a processor unit which is operable under program control during a harvesting operation, following initiation of program operation by a machine operator, to simultaneously monitor both the detected base cutter height and the detected cutting resistance encountered by the harvester as it traverses a particular ground track, and, based upon such detected conditions, to automatedly control the adjustment of the height of the harvester chassis above the ground surface so that the cutting apparatus of the base cutter unit is continuously adjusted to cut at approximately the desired cutting height, within an acceptable vertical movement range or bandwidth, during the course of the harvesting cut operation.

Description

TECHNICAL FIELD

[0001] The present invention relates to a system and method for controlling and adjusting the height of a harvesting implement of a harvesting machine, especially a base cutter of a sugar cane harvester, during a harvesting operation, and without the necessity for continuous user intervention and adjustment. The system and method can be utilized to position the base cutter unit at an optimal height for harvesting and to thereafter automatically control the positioning of the base cutter unit relative to the ground surface during operation, without the necessity for active user intervention and adjustments. Such system and method permits the machine chassis height to be automatically adjusted to account for soil irregularities and to secure more efficient and productive harvesting of a crop.

[0002] The invention is particularly applicable to machines such as sugar cane harvesters that are provided with a base cutter unit attached to the machine chassis and can be effecti...
