An extractor fan assembly for an extractor of a sugarcane harvester comprises a motor, fan blades, and a clamshell hub. The motor comprises an output that rotates about an axis of rotation. The clamshell hub comprises a base and clamp jaws. The base is coupled to the output for rotation therewith about the axis of rotation. The clamp jaws are positioned angularly about the axis of rotation. Each clamp jaw is fastened to and cooperates with the base to clamp a respective fan blade of the fan blades therebetween to position the fan blades angularly about the axis of rotation.

A sugarcane harvester includes a basecutter assembly for cutting sugarcane stalks from sugarcane plants; a chopping section for receiving the sugarcane stalks from the intake and cutting assembly and chopping the sugarcane stalks into billets; a discharge assembly for receiving the billets from the chopping section and discharging the billets to a storage vehicle; and a height adjustment system for automatically adjusting a height of the basecutter to avoid unwanted contact between the basecutter and a ground surface.

A system for supplying electric power to components of an agricultural harvester may include a power storage device and a first agricultural harvester component. The system may also include a first bus electrically coupled to the power storage device and configured to supply electric power at a first voltage to the first agricultural harvester component. Furthermore, the system may include a second agricultural harvester component and a second bus configured to supply the electric power at a second voltage to second agricultural harvester component, the second voltage being less than the first voltage. Additionally, the system may include a converter electrically coupled between the first and the second bus, with the converter configured to reduce the first voltage supplied through the first bus to allow electric power to be supplied to the second agricultural harvester component at the second voltage via the second bus.

A harvester includes a main frame supported on a ground surface for transport along the ground surface, an inlet for receiving a crop, and a separator for separating the crop into a first portion and a second portion. The separator includes a hood having an outlet, and a fan operable to generate an airflow through the outlet. The hood of the separator is movable relative to the main frame between a transport position and a harvest position. In the transport position, the hood is positioned at a first height above the ground surface. In the harvest position, the hood is positioned at a second height, greater than the first height, above the ground surface.

A sugarcane harvester for harvesting sugarcane in a forward direction of travel comprises a chopper, a basket, and a sill. The chopper chops stalks of sugarcane into billets, and comprises a lower drum and an upper drum that counter-rotates relative to one another, each about a respective axis of rotation. The basket is positioned to receive a stream of billets discharged from the chopper. The sill is positioned between the chopper and the basket to guide billets discharged from the chopper toward the basket. A plate of the sill comprises a billet guide surface oriented to guide billets over the sill.
