Abstract: A rotary tiller comprises a frame, a cylindrical drum rotatable relative to the frame, a plurality of tines extending from the cylindrical drum, a motor at least partially disposed within the cylindrical drum, wherein the motor is configured to rotate a motor output member, and a transmission at least partially disposed within the cylindrical drum and configured to engage the motor output member. The transmission is operable to drive rotational movement of the cylindrical drum.

Abstract: An apparatus for forming a water storage material from a biomass input material using supercritical or subcritical fluid processing, the water storage material capable of absorbing a liquid and releasing the liquid. The apparatus utilizes supercritical fluid processing, subcritical fluid processing, charring, or a combination thereof. The apparatus includes a controller configured to control the apparatus. The apparatus further including a processing station configured to hold the biomass input material, and to use the biomass input material for processing into the water storage material.

Abstract: An add-on tillage system is adapted to be mounted on an agricultural device to enhance tilling ability. The add-on tillage system includes a tilling unit with a common tool bar having attached thereto a first set of a plurality of tilling tines or coulters adapted to produce deep grooves in a tilled field. Means are provided for adjusting spacing between the tines or coulters, tilling tines or coulters up and down as a group being loaded by spring force, compressed air pistons or hydraulically actuated rams. A first mount is adapted to receive a tongue with hydraulic operations for mounting to a tractor. A second mount is adapted to receive a tongue with hydraulic mount to an agricultural device adapted to be pulled by the tractor. The add-on tillage system tills surface soil for a clean appearance, providing improved rain/irrigation water absorption, eliminating water run-off and erosion.

Abstract: This tillage machine design utilizes the patented aerator tine by Martindale (U.S. Pat. No. 6,854,525). It is disclosed here in a series of different arrangements within machine frame designs. These frame design protocols protect the farmer from maintenance neglect and unintentional misuse of the tine technology which can lead to inconsistent performance. These designs result in greatly reduced costs of soil-engaging tines. The range of power requirements and concomitant degree of soil fracturing in relation to the number of tine perforations is achieved while enhancing soil erosion control potential. The frame design also embraces two additional technologies for crop residue re-sizing and secondary tillage, creating a one-pass total tillage machine for forage crops, vineyards, orchards, pastureland and row-crop production systems. The machine designs disclosed require less framing steel and ballasting requirements for soil penetration thus extending life of all component parts such as bearings.

Abstract: A vegetation cutter intended to mechanically separate vegetation, such as control of e.g. control weeds and/or other undesired crops or vegetation from desired crops or vegetation on a land surface.

Abstract: A string trimmer is provided with a housing that supports a cutting head. The cutting head includes filaments that are attached thereto at one end for use in cutting associated vegetation. The cutting head is operatively rotated by power supplied from an engine. The cutting head is substantially laterally offset toward on side of the housing member and toward one end of the housing member.

Abstract: A thatch removing attachment for a conventional rototiller. A first mounting bracket is fixed to the rear center of the tiller and has threaded upper surface holes. A second top mounted bracket with several depending spaced spring tooth rake fingers is mounted to the first bracket. Bolt fasteners permit the two brackets to be easily attached or detached from each other. As the rototiller moves the rake fingers thatch the ground underneath as an operator walks behind while the rototiller blades are elevated.

Abstract: A rotary cultivator formed with vertically rotating pairs of transverse-ended ground-penetrating spoke-like end-bladed wheels. Such assembly now adds horizontal pairs of fixed cutter blades spaced respectively one outward from the peripheral path of the wheel-blades and the other radially inward therefrom, plus other laterally projecting blades extending into the "open-cage" formed by each pair of mutually-facing bladed wheels. Standing vegetation against which the cultivator is moved may be severed into segments, additionally miniaturized within the open-cage, and churned into the top soil upon penetration of the wheel blades. Trailing vines or weeds which might otherwise attach to and wind around the shaft are also cut off. Such-sub-unit of interacting cutter blades can be added to present rototillers, or be fabricated as part of the initial unit.
