An extractor for a sugarcane harvester that chops stalks of sugarcane into billets. The extractor comprises a fan, a leaf shredder, and a hub. The fan comprises fan blades to induce a flow of air to separate leaves from billets. The leaf shredder comprises shredding blades to cut leaves prior to their ejection from the extractor. The hub is rotatably driven about an axis of rotation. The fan blades and the cutting blades are coupled to the hub for rotation together with the hub about the axis of rotation.

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 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.

Harvester with adjustable separator

A sugarcane harvester comprises a frame, a knockdown roller, and a telescopic roller support mounted to the frame and to which the knockdown roller is mounted. The roller support is configured to telescope to cause linear movement of the knockdown roller relative to the frame.

A crop divider assembly for a sugarcane harvesting machine that has a first scroll having an upper end and a lower end, a first toe defined along a portion of the lower end of the first scroll, the first toe being a radially inward taper of the first scroll, and a shoe positioned adjacent to a portion of the first toe.

A sugarcane harvester may include a chassis with various discreet and laterally separated mounting locations. Crop divider support modules may be configured to separately and fixedly attach to the chassis at various of the mounting locations, in order to support respective crop dividers in a variety of discreet and laterally separated orientations.

Modular crop divider and base cutter arrangement for sugarcane harvesters

A method and control system are disclosed for orientating base cutters of a sugarcane harvester. A sugarcane harvester may include a crop divider, a rear base cutter, and a front base cutter. An indicator of a position of the crop divider may be determined. A target orientation of the front base cutter may be determined based upon the position indicator. The front base cutter may be adjusted with respect to a chassis of the harvester, in order to place the front base cutter in the target orientation. If adjusting the front base cutter includes moving the front base cutter beyond a predetermined range of motion, the rear base cutter may be adjusted with respect to the ground.

Control of base cutter orientation in sugarcane harvesters

A method and control system are disclosed for adjusting orientations of knockdown rollers for sugarcane harvesters. An upper knockdown roller may be moved along a first adjustment path using a first actuator. A lower knockdown roller may be moved along a second adjustment path using a second actuator. A substantially tangential alignment may be maintained for an outer diameter of the upper knockdown roller and an outer diameter of the lower knockdown roller with respect to a reference point along a cutting path of the base cutter assembly, during or after movement of the upper and lower knockdown rollers.
