The Multi-drill culti rotavator, according to the present invention, is used for cultivating or ploughing the soil and at the same 10 time, for rotavating the soil for agricultural and gardening purpose. Said culti rotavator effectively drills and cultivates the soil preparing it for the irrigation retaining soil moisture increasing soil absorption capacity of the soil. Said multi drill culti rotavator is hung at the rear end of the tractor. It comprises of: Differential Gear Box Assembly 2, Main Body Assembly 3, Bottom differential Gear box Assembly 4, Gear Axle Assembly 5, End Bearing Housing Assembly 6, Drill Bit Shaft Assembly 7.

The proposed invention discloses a multipurpose agro-farming and gardening machine for earth pit digging, tilling, raking, soil bed preparation on plain terrains, as well as in sloppy terrains in hilly areas, weeding, manuring and seeding, with augers, raking rods, compost or manure and seed drop attachments for use in small farms and home gardening. Machine of the proposed invention comprises three rotary soil excavating augers (7) and a linear actuator (2) for driving the assembly of augers to dig into the soil for making pits or for making trenches with adjoining raised beds. Attachments enable adopt double digging practices for preparation of soil beds, manuring and seeding comprising [i] raking rods with spikes for deep digging and [ii] attachments for compost or manure drop and seed drop.

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 discloses an extended type subsoiling smash-ridging machine, comprising a machine body, a smash-ridging device, a connection device, a ditching device, a flattening device and a straw returning device, wherein the smash-ridging device comprises a smash-ridging box comprising a bottom plate, side plates and a top plate, lower bearing seats are mounted in the bottom plate, rib plates are welded between the lower bearing seats, lubricating oil passages are formed between rib plates and the bottom plate, an upper bearing seats are mounted on the top plate and the length of each lower bearing seat is larger than that of each upper bearing seat. By adopting the structure, the invention improves the strength of the lower bearing seats and the rigidity and transmission stability of a transmission shaft; it also facilitates the welding of the rib plates and ensures that lubricating oil smoothly flows within the smash-ridging box.
