Publication number: 20250098574Abstract: A basecutter assembly for a sugarcane harvester includes a cutting spindle powered by a first power source, and a transport spindle powered by a second power source independent of the cutting spindle. A torque sensor is coupled to the cutting spindle. A harvester controller defines a target cutting torque value for the cutting spindle based on a desired crop cut height and determines a current cutting torque of the cutting spindle while cutting the crop. The harvester controller may then control a height of the cutting spindle relative to a ground surface to maintain the current cutting torque substantially equal to the target cutting torque value to achieve the desired crop cut height.Type: ApplicationFiled: September 27, 2023Publication date: March 27, 2025Inventors: Bryan E. Dugas, Peter A. Johnson

Patent number: 12102033Abstract: A harvester including an inlet configured to receive a crop including a stalk, a blade configured to cut the crop into a billet, a sensor configured to detect a three-dimensional appearance of at least a portion of the billet and generate a signal associated with the three-dimensional appearance of the at least a portion of the billet, and a control system having a processor, a memory, and a human-machine interface. The control system is configured to receive the signal from the sensor and programmed to 1) analyze the three-dimensional appearance of the at least a portion of the billet, 2) classify the three-dimensional appearance using an indicator of cut quality and 3) index the indicator of cut quality into the memory.Type: GrantFiled: November 13, 2020Date of Patent: October 1, 2024Assignee: DEERE & COMPANYInventors: Bryan E.
