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.
