A knife for a cylindrical rotor includes at least two sharpened edges adapted to cut materials during land clearing or mulching. The knife further includes a top surface and a bottom surface wherein the knife is shaped as an inverted frusto-square pyramid. The knife may further include a tapered sidewall defining one sharpened edge. The angle may be about 30? to about 60?. The knife may have four sharpened edges. The knife further may include an aperture that may be equidistant from the four sharpened edges. The knife is adapted to be moved when one sharpened edge becomes dull. The knife may further include a conical countersunk aperture. The knife may have a thickness of about ? to about ?.

A gardening system includes a drive shaft operably coupled to first and second shafts for driving the first shaft in a first direction and the second shaft in a second direction. A first ground manipulation device is attached to the first shaft. A second ground manipulation device is attached to the second shaft.

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.

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.

A method of stacking dethatchers includes pivoting an upper portion of a handle on a first dethatcher toward a front end of a frame on the first dethatcher, upon pivoting the upper portion of the handle toward the front end of the frame, exposing a rear support point defined by a lower portion of the handle, and stacking a second dethatcher on the first dethatcher so that the second dethatcher is supported on the rear support point defined by the lower portion of the handle and a front support point defined by the upper portion of the handle.

A tilling apparatus and a method of tilling soils which includes the use of a rotational shaft having a number of cutter assemblies located at spaced apart locations on the shaft in which each cutter assembly has a multitude of blades which rotate as the rotary shaft rotates to form a plurality of spaced apart trenches having the same spacing as the spacing of the cutters, and a width caused by the width of the blades. As the blades dig the trench, the soil contacted by the blades is granulated and is tossed about by the spinning blades so that some soil falls back into the trench and some falls along the periphery of the trench to form rows of aerated granules which promote enhanced growth of plants or seeds in the trench and along the edge of the trench to improve the yield of pasture having the trenches. Various attachments can be provided on the tilling apparatus, either in front of or towards the rear of the spinning blades for different purposes, such as rippers, seeders, levellers, or similar. The advantage of the tilling apparatus is that the soil is formed into granules which are used to form an aerated array of soil granules having enhanced growing properties for plants.

Implement apparatus may be configured to displace ground material. For example, an implement may include an extension member coupled to a roller apparatus. The extension member may be coupled to a mounting apparatus configured to mount each of a crumbler, a hipper, a bermer, a bermer, crumbler combination apparatus, or a chopping apparatus.

A representative system for preparing a field for planting includes: first disk blades, each exhibiting a first offset angle with respect to a tilling direction; second blades, each exhibiting a second offset angle with respect to the tilling direction; ripper shanks disposed behind the second disk blades; third disk blades disposed behind the ripper shanks, each exhibiting a third offset angle with respect to the tilling direction; fourth disk blades, each exhibiting a fourth offset angle with respect to the tilling direction; and a chopper reel disposed behind the fourth disk blades; wherein, with respect to magnitude, each of the first offset angle and the second offset angle is greater than each of the third offset angle and the fourth offset angle.

A knife for a cylindrical rotor includes at least two sharpened edges adapted to cut materials during land clearing or mulching. The knife further includes a top surface and a bottom surface wherein the knife is shaped as an inverted frusto-square pyramid.
