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 method for sharpening cutting knives carried by a cutter drum in a housing of an agricultural vehicle includes: rotating the cutter drum while keeping a sharpening door closed so an overpressure is created inside the housing, the sharpening door shielding a sharpening stone from the cutting knives while creating the overpressure; opening a transition door of the housing below the cutter drum to eject crop material through the open transition door; opening the sharpening door to expose the cutting knives to the sharpening stone and closing the transition door; grinding one or more of the cutting knives with the exposed sharpening stone; and closing the sharpening door to shield the sharpening stone from the cutting knives after grinding.

An agricultural vehicle header having a frame, a front conveyor, and a rear conveyor. The frame extends in a lateral direction from a first end to a second end and has a leading edge, and a feeder housing opening positioned behind the leading edge with respect to a forward direction. The front conveyor is attached to the frame behind the leading edge with respect to the forward direction, and includes a front movable surface configured to move an adjacent portion of crop material towards the feeder housing opening. The rear conveyor is attached to the frame behind the front conveyor, and has a rear belt having an operative surface that faces in the forward direction and is configured to move an adjacent portion of crop material towards the feeder housing opening. An agricultural vehicle having such a header is also provided.

Various types of lawnmowers are disclosed that include a cutter housing having a chamber wall and a discharge opening therein. A mulch gate can be provided with an interior scroll-shaped face and can be pivotably attached to the cutter housing so as to be movable between an opened gate position and a closed position. In the opened position, the mulch gate is positioned such that the discharge opening is opened to an exterior of the lawnmower to allow clippings to pass therethrough and out of the lawnmower. In the closed position the mulch gate closes the discharge opening to provide a mulch mode in which clippings remain in the cutter housing for added cutting by the lawnmower blade. When the mulch gate is in the closed gate position, the interior scroll-shaped face of the mulch gate can be substantially continuous with a wall interior surface of the chamber wall.

A combine including a feeder housing for receiving harvested crop, a separating system for threshing the harvested crop to produce grain and residue, a residue spreader wheel spinning at a speed for expelling the residue from the combine, a residue deflector positioned at an angle for deflecting the expelled residue in a predetermined direction, and a controller. The controller is configured to determine a heading of the combine, determine wind effects on the expelled residue based on an observation of the expelled residue at the determined heading, and adjust at least one of the speed of the residue spreader wheel or the angle of the residue deflector based on the wind effects to achieve a desired residue spread at the determined heading.

A harvesting machine is disclosed along with a method of operating the harvesting machine. The harvesting machine includes a frame having a first end and a second end. A rotatable pick-up head is pivotally mounted on the first end and is capable of urging a crop into the machine. A cutting mechanism is mounted on a bottom plate of the frame for cutting the stems of the plants and forming a movable web. First and second moisture removal mechanisms are positioned downstream of the cutting mechanism, and each includes a suction roll and a press roll. A moving belt forms a closed loop around the pair of suction and press rolls, and has a plurality of apertures formed therethrough. The moving belt forms first and second nips between each pair of suction and press rolls for squeezing moisture out of said stems as the movable web is routed through the first and second nips.

A method of collecting material with a harvester when a storage vehicle is spaced from the harvester includes moving material from the field into the basket, actuating the conveyor for a first time period when the sensed parameter is above the set amount, transporting a first portion of the material a first distance with the actuated conveyor, after the first time period has elapsed, stopping the conveyor to store the first portion of the material on the conveyor, after the first time period has elapsed, if the conveyor can store more material, actuating the conveyor for a second time period, transporting a second portion of the material a second distance with the actuated conveyor and transporting the first portion of the material a third distance with the actuated conveyor, and if the conveyor cannot store more material, alerting an operator that the conveyor is full.

An automated hemp field harvester can be driven by a tractor or attached to various types of self-propelled machines. The automated hemp field harvester has a set of two combing belts that rotate up vertically with a plurality of comb assemblies for stripping the buds and flowers from the hemp plant as the automated hemp field harvester is directed down the row of hemp plants. A set of winged plates in front of the combing belts gather the hemp plants and directs them into the drive assemblies. The comb assemblies are inclined in an upward direction and strip the buds and flowers from the stalks and stems. There is a deflecting plate at the top end of the combing belts to deflect the buds and flowers in a controlled manner to a product discharge conveyor belt to be loaded into a trailer or wagon for removal from the field.

A mulching apparatus for attachment to a lawnmower includes a cutting assembly separate from the mower blades, wherein the grass clippings are finely cut and then dispersed onto the ground surface. A spreader assembly receives the mulched grass clippings from the cutting assembly and disperses the mulched grass clippings onto a ground surface. Optionally, the mulching apparatus includes a feeder assembly to facilitate supplying grass clippings to the cutting assembly.

Various types of lawnmowers are disclosed that include a cutter housing having a chamber wall and a discharge opening therein. A mulch gate can be provided with an interior scroll-shaped face and can be pivotably attached to the cutter housing so as to be movable between an opened gate position and a closed position. In the opened position, the mulch gate is positioned such that the discharge opening is opened to an exterior of the lawnmower to allow clippings to pass therethrough and out of the lawnmower. In the closed position the mulch gate closes the discharge opening to provide a mulch mode in which clippings remain in the cutter housing for added cutting by the lawnmower blade. When the mulch gate is in the closed gate position, the interior scroll-shaped face of the mulch gate can be substantially continuous with a wall interior surface of the chamber wall.
