A machine for picking up rocks from soils having a structure suitable for being moved over the surface of the soil, by means of a pair of side wheels, being towed by a tractor vehicle from which it receives movement through its power take-off. The machine has rock extraction and uprooting elements incorporated on the advancing edge of the machine, made in the form of teeth, associated with a tooth bar region of the structure of the machine, having certain play, a rotating movable feed reel with teeth, a conveyor belt for lifting said rocks up through an inclined plane from a leading edge to a trailing edge located at a greater height; a rock collection and accumulation hopper arranged on the trailing edge.

A rotary harrow tool includes a body with a lower part that has, in the zone of its lower end, a working portion capable of and designed for being engaged and displaced in the soil and is equipped with at least one element attached in the form of an insert constituting at least the active front edge and the active adjoining elongated face of the working portion at least of the tool. The upper insert, situated opposite the free or lower end of the second part, has a rounded inner corner. Each insert has a substantially plane structure with, viewed in section along a plane perpendicular to the active edge and to the active face, a variable thickness that decreases from its front longitudinal rim forming the active edge to its rear longitudinal rim mounted in the receiving site, while forming a bevel by cooperation with the support piece.

Methods and systems for applying a uniform layer of a substance such as a hydrogel or other fluid substance beneath a soil surface with minimal or little surface disturbance to the plants, the plant roots and the soil located on or slightly below the applied surface area. Embodiments include injecting a fluid substance into soil using at least one injector probe, a driver to drive the at least one injector probe into and out of the soil to and from a target depth, and a rotator mechanism configured to rotate the at least one injector probe about a central axis from one angular position to another angular position at the target depth.

The invention relates to a tool having a hard material for processing mineral and/or plant-based material layers, in particular of traffic areas and/or agricultural floor areas or combinations thereof with one another. According to the invention, at least one part of the cutting element is formed or covered with a hard material containing fullerite or formed from fullerite. The wear resistance of the tool can be significantly improved by the extremely hard material.

A system and method cuts and increases surface area of surface stubble material while contemporaneously mulching, tilling and aerating the soil. A discoidal coulter blade is configured with sharpened areas at the circumference and one or more inside bevel for cutting the surface stubble as well as reducing the downward pressure required for the blade to enter the type and depth of soil desired. The bevel aids in coulter blade lifespan, ensuring a self-sharpened blade, and allows mating with a second coulter blade.

A vertical tine tiller having vertically oriented tine assemblies that are configured to rotate about vertical axes is provided. The tiller includes a power source that drives a horizontally-aligned driveshaft, which can selectively drive a transmission assembly. Horizontal rotation of the driveshaft is directly transferred into vertical rotation of a pair of drive rods to which the tine assemblies are attached.

The objective of this application is to reveal enhancements and extensions of the previously patented Tractor-Mounted Excavation Implement, awarded Nov. 24, 2015 to Bruce Wade McGee, and assigned U.S. Pat. No. 9,194,103 B2. McGee's Tractor Mounted Excavation Implement is useful in small-scale construction, hobby farming or gardening, landscaping, irrigation, utilities and pipe laying, roadside or city development and maintenance in some areas, land-owner maintenance, and possibly firefighting with rapid excavation needs in some less dense forests. This application adds apparatuses to include usefulness in creating gardening or landscaping beds, and shallow graded excavations for sidewalk or simple slabs. Additionally, several other changes are proposed that enhance and extend usefulness of the implement, including improved power diversion to the implement's apparatuses, improved cutting element configuration, and an enhanced axle that more effectively loosens soil for excavation and sweeps excavated soil laterally.

Apparatus for mulching organic matter such as brush and trees are disclosed. The apparatus have cutting teeth that include cladding for increasing the wear-resistance of the teeth. Cutting heads and vehicles that incorporate such teeth are also disclosed.
