The invention relates to an agricultural seeding machine, in particular to a straw crushing and inter-furrow collecting-mulching no-tillage seeder. A straw-crushing device, a guide device, a fertilizer discharging device, and a furrowing and seeding device are sequentially arranged on a rack from front to back. According to the guide device, a plurality of straw-crushing guide assemblies having installation positions capable of being horizontally adjusted are arranged on an adjustment crossbeam, are in a prow shape, and each consist of a rear vertical back plate formed with a fertilization port, and two front symmetrical oblique guide plates. Straw is orderly spread on straw mulching belts between seeding belts while being crushed within the working range, and thus, the seeding belts are free of straw obstacles. The straw crushing and inter-furrow collecting-mulching no-tillage seeder is high in working integrity, easy to assemble, and low in energy consumption.

A cutting device for comminuting crop residues or catch crops on agricultural land is described. The cutting device is designed to be rotatable around a center longitudinal axis (MLA) and, to this, it has at least one bearing unit for rotatably mounting. The cutting device includes first and second respectively elongated cutting blade element, as well as at least one holding means for holding the cutting blade elements. The elongated cutting blade elements each comprise a cutting edge section and a connecting section lying opposite to the cutting edge section and are radially orientated in such a way that the cutting edge sections of the elongated cutting edge sections are arranged at a radial distance from the center longitudinal axis. The cutting blade elements are directly connected to each other with the aid of the holding means, wherein the connecting sections of the cutting blade elements are arranged directly adjoining one another in a center region of the cutting device receiving the center longitudinal axis (MLA).

The instant invention is a machine/implement used for soil preparation, fertilizing and seeding intended for farming and gardening that mounts on a standard three point hitch and is powered by a tractor's power-take-off (PTO). The implement integrates the processes of ground breaking, tilling, fertilizing and planting in one adjustable unit. The adjustments include the spacing and depth of the ground cutting and tilling blades and the openings of the fertilizing ports to prepare the ground for planting in defined strips leaving the majority of ground only lightly disturbed. To achieve these goals, the apparatus is comprised of two frames, a lower one that contains the blades that break the ground crust ahead of the tiller tines that grind the soil into finer particles for planting. The lower frame also has a rear flap that levels and marks the tilled soil and also supports seed boxes with a mechanism that allows the seeder/seeders to set seed at a constant depth on uneven ground. The spacing of the seed boxes are determined by mounting holes in the apron. The upper detachable frame contains a bin that filters, holds and dispenses fertilizer by mixing it down through adjustable ports directly above and forward of the tiller blades to be mixed with the earth during tilling thus making it possible to break the ground, till, fertilize and seed in a single pass.

A land preparation implement includes a rotatable drum assembly that includes a tool assembly. The tool assembly includes a tool holder and a tool. The tool includes a plurality of cleats. The tool holder includes a plurality of cleat supports. The cleats and the cleat supports cooperate to facilitate releasable coupling of the tool to the tool holder.

A steam shank rotor assembly having rigid teeth connected to a hollow shaft via teeth mounts which collectively allow steam to circulate from the hollow shaft to the nozzles located near the working end of the teeth, and then into the soil. This invention provides an agricultural apparatus that simultaneously tills and disinfects soil with the use of steam.

An autonomous travelling work vehicle includes at least one obstruction sensor and circuitry. The at least one obstruction sensor is to detect an obstruction in a travel route along which the autonomous travelling work vehicle is configured to travel. The circuitry is configured to determine whether the at least one obstruction sensor operates under a proper operation environment and to determine whether a malfunction occurs in the at least one obstruction sensor if the at least one obstruction sensor is determined to operate under the proper operation environment.

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.

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.

Embodiments determine a draft force based on forces at hitch points of the tractor, to determine type of soil, on which the tractor is plying. Embodiments determine rotational peripheral velocity of the implement and forward velocity of the tractor. Embodiments provide recommendations for adjusting the rotational peripheral velocity of the implement and the forward velocity of the tractor based on the soil type, the rotational peripheral velocity of the implement, and the forward velocity of the tractor. The recommendation is provided, if the ratio of the rotational peripheral velocity of the implement and the forward velocity of the tractor falls outside an optimal range.

An apparatus for in-situ reconditioning of a media used in an effluent treatment bed is disclosed, in which passage of effluent has become impeded by clogging matter within the media, the bed having been planted with vegetation having roots extending into the media. The apparatus includes a frame supporting a superstructure operable to be disposed above a surface of the bed when in operation, a pair of spaced apart arms having distal ends extending downwardly from the frame, and an agitator extending between the pair of arms and having tines for sub-surface tilling of the media. The agitator is coupled to a drive system operable to cause rotation thereof. A lifter bar is disposed between the arms above the agitator such that when the frame is advanced through the bed the lifter bar passes through the bed below a primary root zone of the vegetation lifting and separating the primary root zone while the agitator tills the media below causing clogging matter to be separated from the media.
