An agricultural cutting mechanism for use with an agricultural machine has a disk rotatable about an axis of rotation, a post secured to the disk, a blade, and a yieldable blade retainer. The blade is removably secured to the disk. The blade comprises a keyhole in which the post is positioned. The blade retainer is secured to the disk to move relative thereto between a blocking position blocking radially inward movement of the blade to the replacement position so as to maintain the blade in the use position and a service position releasing the blade to move radially inward to the replacement position for replacement of the blade with another blade. A blade for use with an agricultural cutting mechanism is also disclosed.

A conveyor system of a sugarcane harvesting machine includes an inclined conveyor having a first shaft at a lower end and a second shaft at an upper end thereof. The belt is driven along the inclined conveyor between the first shaft and the second shaft, and the belt includes an upper portion and a lower portion between the lower end and the upper end. A floor is partially disposed between the upper portion and the lower portion of the belt, and a wiper is coupled to a bottom end of the belt such that the wiper extends from the belt in a direction towards the floor. As the upper portion of the belt travels from the lower end to the upper end of the inclined conveyor, the wiper moves with the belt and contacts and moves material that collects on a top surface of the floor.

A separator for a crop harvester configured to harvest sugarcane. The separator includes a frame having: i) an inlet configured to receive cut sugarcane, wherein the cut sugarcane includes cut stalk and crop residue, ii) a cut stalk outlet configured to discharge the cut stalk from the frame; and iii) a crop residue outlet. An extractor is operatively connected to the crop residue outlet. The extractor includes a tapered nozzle disposed adjacently to the crop residue outlet and a fan disposed adjacently to the tapered nozzle, wherein the tapered nozzle is configured to provide a pressure differential between the crop residue outlet and the fan in response to air flow provide by the fan. The tapered nozzle, in one embodiment, is a truncated cone having a smaller end disposed adjacently to a flow of cut crop, wherein the fan draws air through the truncated cone to separate the crop residue from the cut stalk.

A set of conveyor rollers for use in agricultural machines, especially those of the stalk and tall plants harvester type, including front elements arranged in an independent front platform. The conveyor roller set includes a front aperture (6) for receiving the harvested material (MC) from a platform (P), the set including at least one upper roller (20a) and at least one lower roller (20b) disposed in the platform (A), wherein the upper conveyor roller (20a) has a diameter (D) greater than the diameter (d) of the lower conveyor roller (20b).

A system includes an aerial sensor platform including a spectral imaging device, a position sensor, and an orientation sensor and includes a ground-based sensor platform including at least one soil sensor. The system also includes a computing device with instructions that are executable by a processor to obtain spectral imaging data collected by the spectral imaging device and soil data collected by the at least one soil sensor. The spectral imaging data represents a particular field of view (based on data from the orientation sensor) of a particular geographic region (based on data from the position sensor) of a crop field and the at least one soil sensor is associated with the particular geographic region. The instructions are further executable by the processor to schedule an agricultural activity based on the spectral imaging data and the soil data.
