A sugarcane harvester comprises a frame, a basecutter coupled to the frame for translation relative to the frame, a knockdown roller mounted for translation relative to the frame, and a synchronizer configured to translate the knockdown roller in unison with the basecutter so as to maintain a position of the knockdown roller relative to the basecutter upon translation of the basecutter relative to the frame.

An elevator assembly for a harvester may include an elevator extending within between proximal and distal ends. The elevator may be configured to carry harvested crops between its proximal and distal ends. The elevator assembly may also include a storage hopper at a location adjacent to the distal end of the elevator. The storage hopper may include a rear deflector and a hopper gate. The hopper gate may be movable between a discharge position, at which the hopper gate exposes a discharge opening of the storage hopper, and a storage position, at which the hopper gate covers the discharge opening to prevent harvested crops from being discharged from the elevator assembly. Additionally, when the hopper gate is moved to the storage position, the hopper gate and the rear deflector may at least partially define a storage volume adjacent to the distal end of the elevator for storing the harvested crop.

A sugarcane harvester for harvesting sugarcane including a cutter configured to cut sugarcane into a sugarcane mat. An extractor is operatively connected to the cutter, and includes a fan housing having an inlet configured to receive the sugarcane mat and an outlet configured to discharge crop debris. A fan is located in the fan housing to move the sugarcane mat through the fan housing and includes a motor, blades rotatably coupled to the motor, and a blade angle of incidence mechanism operatively connected to the blades, wherein the blade angle of incidence mechanism adjusts the angle of incidence of the blades with respect to the motor. Sensors identify an air flow through the fan housing or a load placed on the motor during movement of the sugarcane mat through the fan housing. The angle of incidence of the blades is adjusted based on one or both of the air flow through the fan housing or the load placed on the motor.

A harvester that includes an elevator, a spreader conveyor and a secondary extractor. The elevator includes a lower proximal end that receives harvested material and a higher distal end that dispenses the harvested material. The spreader conveyor includes a proximal end that receives the harvested material from the elevator and a distal end that dispenses the harvested material. The secondary extractor includes an inlet and an outlet, where it extracts debris from the harvested material dispensed from the distal end of the spreader conveyor into the inlet and expels the debris out of the outlet. The spreader conveyor can include a spreader belt that rotates in an endless loop, where the harvested material received from the elevator spreads out on the spreader belt. An extractor fan can create air flow to pull debris through the secondary extractor. The spreader conveyor can throw harvested material into the air flow.

A header to be coupled to an agricultural machine, such as harvesters of tall and stemmed plants, and sugar cane and sorghum. The header includes at least one base cutting assembly mounted in a floating manner in relation to a structural frame of the header through at least one pantographic arm and at least one actuator.
