The permanent lawn mower, or inground lawn mower, is designed to be an alternative to conventional mobile mowing. Its focus is small grassy areas that are dangerous or impractical to mow by other means. In a first embodiment, the system includes three primary components: a drive unit that supplies rotational motion; a cable that carries rotational motion away from the drive unit, and one or more cutting heads that convert the rotational motion into a cutting action. In a second embodiment, the drive unit is combined with the cutting head, avoiding the need for a cable to carry rotational motion.

A stubble stomper is disclosed that attaches to a crop harvesting header on an agricultural machine. The stubble stomper includes a mounting bracket that attaches to the header frame of the crop harvesting header, a hinge assembly that is rotatably attached to the stomper mounting bracket and is rotatable between a default position and a breakaway position, and a stomper shoe that is pivotally attached to the hinge assembly. The stubble stomper has a self-resetting feature from the breakaway position that allows the stubble stomper to re-engage to its default position as the agricultural machine moves in a forward direction of travel.

A material processing tool assembly includes a tool for material processing having a base section and a processing section extending from the base section; and a tool mounting block mountable on an outer surface of a support base. The mounting block has a base surface and a tool mounting surface intersecting the base surface. The base surface has a protuberance extending away therefrom and spaced apart from the tool mounting surface to define a tool receiving gap between the protuberance and the tool mounting surface. The base section of the tool is snugly received in the tool receiving gap between the tool mounting surface and the protuberance in abutment with the tool mounting surface, the processing section of the tool extending past the protuberance. A displaceable material processing head and method of mounting a material processing tool to a mounting block secured to a displaceable head are also discussed.

An irrigation and harvesting system includes one or more center pivot irrigation assemblies. The center pivot irrigation assembly includes a hollow shaft attached to an area of land; one end of a hollow member is attached to the hollow shaft, wherein the hollow member pivots around the hollow shaft, and wherein the hollow member carries irrigation water; a second end of the hollow member is connected to a wheel in contact with the ground, and the wheel is driven at a controlled speed; and a traction device including harvesting equipment is attached to the hollow member.

Vegetation cutting apparatuses may include a wheeled apparatus frame. A cutting assembly may be carried by the wheeled apparatus frame. The cutting assembly may include an elongated chain support member having a chain support member edge. An elongated debris removal slot may extend into the chain support member from the chain support member edge. A cutting chain may be configured to traverse the chain support member edge of the chain support member. An engine may drivingly engage the cutting chain.

An agricultural system includes a plurality of organic devices for controlling weeds in a planted field, the organic devices being positioned between respective adjacent rows of planted matter in a field. Each the organic devices includes a pivotable shaft having an upper end and a lower end, and a weed-control unit attached to the lower end of the pivotable shaft. The weed-control unit includes a rotatable blade for mowing weeds growing between the adjacent rows of the planted matter. The system further includes at least one motor coupled to one or more of the organic devices for driving the rotatable blade of each weed-control unit.

A mower blade assembly attaches to a rotatable spindle and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle. The retaining plate defines a second pin aperture. A movable pin plate comprises a pin. A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade to the mounting plate. The blade is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate. Another embodiment includes a force finger.
