Disclosed is an assembly, device to drill holes and sow seeds or manure in soil and methods thereof. The said assembly comprising: a soil probe a seed feed conduit, said conduit interior being in communication with the interior of said soil probe a soil poking rod a platform coupled to a pair of compression means and adapted to generate force an arrangement of three links adapted to provide a pantograph mechanism for vertically moving the said poking rod and wherein pantographic arrangement of links is initiated to magnify the force exerted by heels so as to push down the poking rod to form a hole in soil and simultaneously allow seed to move in the hole and after maximum compression by the platform, the restoring force return the poking rod in backward stroke while blocking the seed feed conduit and repeating the cycle in each stride.
