A bagger attachment for use with a stand-on lawn mower. The bagger includes, in some embodiments, an impeller, a duct, and one or more bags which are covered by a hood. The hood is attached to a pivot frame that allows movement of the hood between open and closed positions. The bagger attachment may also include a frame assembly that facilitates mounting and removal of the bagger attachment from the mower. The bagger attachment may either contain removable bags, or may include a discharge door for dumping the clippings.

A mobile platform comprises a header, a biomass processor, and a guidance system. The header is configured to harvest biomass. The biomass processor is configured to compact the biomass into a multitude of compressed biomass pieces. The guidance system is configured to guide the mobile platform at a speed determined by the operating capacity of the mobile platform.

A forage harvester includes a post-accelerator disposed in an interior of the forage harvester, which post-accelerator includes a conveying fan that rotates about a rotary axle. The post-accelerator is partially enclosed by a housing that is open in sections and that extends in sections into a crop-conveyance path. An extent of the extension into the crop-conveying path is adjusted by displacing the post-accelerator relative to the housing. The forage harvester also includes a wall disposed opposite an open section. The rotary axle includes ends that are mounted in bearing supports disposed on the housing via one end to be pivotable about a pivot axle. Each of the bearing supports are connected to an actuator at a free end opposing the one end disposed on the housing.

A system for collecting biomass for the production of ethanol is disclosed. Also disclosed is a method for collecting biomass. The method comprising: harvesting biomass with a combine, wherein a first portion of the biomass is substantially forced against the ground and a second portion of the biomass passes through the combine and forming bales comprising the second portion of the biomass. According to an aspect, the bales comprise a majority of the second portion of the biomass and a small part of the first portion of the biomass.

A mobile platform biomass harvester has a header, a biomass processor, a storage container, a guidance system, an engine, an electric generator, and a guidance system. The header harvests biomass. The biomass processor includes a shredder, a press, a dryer, and a densifier. The densifier compacts the biomass into a multitude of compressed biomass pieces. The storage container receives compressed biomass pieces from the biomass processor. The guidance system guides the mobile platform at a speed determined by the operating capacity of the mobile platform. The engine generates shaft power. The electrical generator converts the shaft power to electricity to power the guidance system.

A mulching device 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. In one embodiment, the cutting assembly includes an auger that compresses the grass clippings prior to cutting them. The mulching device may also include a separation chamber for separating the grass clippings from the forced air exiting the mower deck, so that the grass clippings may be cut in an environment separate from the forced air. In another embodiment, the mulching device includes a dispersion assembly for spreading the cut grass clippings onto a ground surface. The dispersion assembly may include a chute extending from the forced air outlet to a position adjacent the cutting assembly, wherein the forced air exiting the separation chamber is directed onto the cut grass clippings to disperse the cut grass clippings onto the ground surface.

An agricultural harvesting machine includes a working assembly for processing a crop flow and a discharge accelerator for the processed crop that is designed as a unit to be installed in its entirety into an operating position (P.sub.B) downstream of the working assembly in the flow path of the crop stream. The discharge accelerator unit is readily deinstalled from the operating position (P.sub.B).

Systems and methods are provided for controlling operation of one or more operable components of or otherwise associated with a crop transfer device of an agricultural harvesting machine. Data indicative of a position of an unloading spout of the crop transfer device is used to determine an operational setting for a crop transfer device for controlling a discharge trajectory of material from the unloading spout. One or more operable components of or otherwise associated with the crop transfer device can be controlled accordingly.

A header assembly for a harvesting machine comprising a primary cutter head for cutting the crop, and a feeder for feeding the cut crop into the mouth of a crop processing mechanism. The assembly further comprises a secondary scissor-action cutter head trailing behind the primary cutter head for cutting stalks left behind by the primary cutter head, the secondary cutter head coupled to the rear of the header and supported by ground engaging rollers. The rollers include at least one support cylinder having a circumferentially discontinuous ground engaging outer surface operative to perform a preliminary processing of at least one of the crop residue and the soil.
