Claim:
An agricultural mechanized system for pulling-off and chopping stubs of cotton plants and similar agricultures, which applies to an agricultural machine (C) coupled to a conventional tractor (T), the prevailing characteristic of which is based on a mechanized system for extracting remains of plants buried in the ground, preferably cotton and similar agricultures, presenting in a preferential attainment a machine provided with a support frame ( 2 ) with a front part ( 3 ), a rear part ( 4 ), a pair of transversally opposed parallel sides ( 5 and 6 ) which extend themselves axially between the ends of the referred front and rear parts ( 3 and 4 ) and on an adjoining basis to these over at least a pair of wheels ( 7 and 8 ); the system comprising: a plowing set ( 10 ) at the front area ( 3 ) provided with a pair of cutting wheels ( 14 and 14 â€²) a pair of adjustable plowing blades ( 16 and 16 â€²) between a first position above the ground and a final position of penetration in the ground, which is longer than the stubs radicular portion depth; a chopper set ( 12 ) with blades ( 96 ) which chop the referred stubs into a particulate material inside a housing at the rear area ( 13 ); a pair of front vertical plates operably connected to the tractor, a pair of rear vertical parallel plates operably connected to the plowing blades, and two pairs of parallel side arms linking the front vertical plates to the rear vertical plates whereby the plowing set ( 10 ) is mounted by a parallel linkage system of variable positioning; at least a stub pulling-off set ( 11 ) arranged between the referred plowing set ( 10 ) and chopper set ( 12 ) and in communication with these by transfer of stubs from the front area ( 3 ) to the chopper set ( 12 ) housing and a universal movement system ( 9 ) operatively for the synchronous movement of the referred plowing set ( 10 ), pulling-off set ( 11 ) and chopper set ( 12 ), wherein the pulling-off set ( 11 ) comprises a circulating stub pinching device ( 52 , 53 and 56 ) along the pulling-off set and a pair of rotating blades ( 57 ) with supplementary cutting edges for the cutting of the radicular portion of the referred stubs.
