A cane pickup and separation device mountable to a vehicle, the front of which is depicted in FIG. 1 and identified by reference No. 2. The device includes at least two sorting augers with auger tips, a frame, a separation wall, and a pickup spiral. The sorting augers each have auger tips that are adapted to be positioned slightly above ground level. The sorting augers diverge relative to one another and are inclined upwardly and rearwardly at similar inclined angles θ to the horizontal to define a diverging gap. Behind the augers is the upwardly and rearwardly inclined separation wall. The separation wall is rearward of the pair of augers and extends substantially across the diverging gap. The frame is mountable to the vehicle and is adapted to support the pair of sorting augers and the separation wall. The device further includes at least one pickup spiral set at a shallower angle π inclination to the horizontal than the steeply inclined angle θ.

Systems and methods for geospatial yield mapping by managing and modeling a system-based delay between crop location and crop sensing. The system stores a plurality of yield rate values indicative of crop yield detected by a sensor and a plurality of geospatial location values as time sequence data sets. The system then maps a yield rate value to a geospatial location value by determining an offset indicative of a total delay time from when the crop is cut from the field to when the crop is detected by the yield sensor. In some implementations, the delay value is determined as an integer multiple of a defined sampling frequency and is determined as a sum of a plurality of delay component values each indicative of a portion of the total delay time associated with a different one of a plurality of component systems of the crop harvester.

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 sugarcane harvester may include a base cutter configured to cut sugarcane, a chopping device in communication with the base cutter to receive the sugarcane cut by the base cutter, the chopping device configured to chop the cut sugarcane into billets, an elevator in communication with the chopping device, the elevator configured to transport the billets out of the sugarcane harvester, the elevator having a discharge end, a forward billet deflector beyond the discharge end of the elevator distant the discharge end, a rearward billet deflector proximate the discharge end and spaced from the forward billet deflector such that the billets fall between the forward billet deflector and the rearward billet deflector and a powered actuator to move the rearward billet deflector to adjust a discharge direction of the billets.

A non-row sensitive forage harvester header is formed with a single rotary member driven by a simplified drive mechanism coupled to the primary drive of the forage harvester to which the header is mounted. A horizontal drive shaft transfers the rotational power laterally to a gear box. The vertical output shaft from the gearbox has a first drive sprocket mounted thereon to connect directly with a drive chain fixed to the crop transfer disks, and a second drive sprocket mounted thereon and coupled to a drive chain entrained around a driven sprocket on the cutting disk to provide a drive speed differential with respect to the crop transfer disks. The crop guides are formed with rearwardly angled transfer arms cooperable with sweeper members on the crop transfer disk to direct the severed crop into engagement with the transfer disks for feeding into the forage harvester.

An elevator assembly for a harvester may include an elevator housing and an elevator extending within the elevator housing between a proximal end and a distal end. As such, the elevator may be configured to carry harvested crops between its proximal and distal ends. Furthermore, the elevator assembly may include a storage hopper extending from the elevator housing at a location adjacent to the distal end of the elevator. The storage hopper may include a conveyor extending within the storage hopper between a first end and a second end, with the conveyor configured to carry the harvested crops between its first and second ends towards a discharge opening of the storage hopper.

A conveyor guide unit for use in an elevator of a sugarcane harvester comprises a housing, an axle positioned in and supported by the housing, and a rotor mounted to the axle for rotation about a rotation axis and configured to interface with a conveyor of the elevator. The axle and the rotor mounted thereto are selectively repositionable axially along the rotation axis relative to the housing for lateral adjustment of the rotor relative to the conveyor.
