A harvester includes a feed system operable at a feed speed and configured to feed a crop towards a blade. The blade is configured to cut the crop into crop billet and is operable at a cutting speed. The harvester further includes an optical sensor configured to generate a signal corresponding to a length of the crop billet and a control system with a processor, a memory, and a human-machine interface. The control system is configured to receive the signal and programmed to adjust one or both of the cutting speed or the feed speed based on the signal.

A chopper system for a sugarcane harvester comprises a chopper and a timing-adjustment tool. The chopper comprises a first chopper drum mounted for rotation about a first axis of rotation and comprising blades, a second chopper drum mounted for rotation about a second axis of rotation and comprising blades that cooperate with the blades of the first chopper drum to sever sugarcane stalks into billets upon rotation of the first and second chopper drums respectively about the first and second axes of rotation, and a gearbox that coordinates rotation of the first and second chopper drums relative to one another to establish a timing of operation between the blades of the first and second chopper drums. The timing-adjustment tool removably mounts to the chopper to adjust the timing of operation.

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.

A method of controlling an agricultural harvesting machine having a harvesting device configured to engage and cut crop on a field. The method includes receiving an indication of field topography in a first area of the field prior to the first area being harvested, controlling a position of the harvesting device to harvest the crop in the first area based on the indication of field topography in the first area, receiving in-situ data from the first area of the field after the first area is harvested by the harvesting device, receiving an indication of field topography in a second area of the field prior to the second area being harvested, and controlling the position of the harvesting device to harvest the crop in the second area based on the in-situ data and the indication of field topography in the second area.
