Abstract
Abstract A farming implement, particularly for row cultivation, wherein the operator device comprises a mill or harrow having substantially vertical axes or slightly inclined to the vertical, and connected to the tractor by the interposition of an automatic device for transverse movement relative to the tractor, transversely displacing the implement and securing it at any intermediate position.

A farming implement, particularly for row cultivation, comprising a fork frame (2) adapted to be connected to a tractor; a support (1) for carrying operating tools (15); oleodynamic cylinder means (5) having one end (7) pivotally mounted to a rear portion of said fork frame (2); two spaced apart parallel pivoted arms (3,3') for connecting and supporting said support (1) together with said tools (15) to said fork frame (2); first means having a first component for pivotally mounting a first end of one of said pivoted arms (3,3') and a second component for pivotally mounting a corresponding first end of the other of said pivoted arms (3,3') to portions of said fork frame (2) spaced forwardly of the portion mounting said oleodynamic cylinder means (5); second means (4') having a first component associated with the other end of one of said pivoted arms (3,3') and a second component associated with the respective other end of the other of said pivoted arms (3,3'), said components being associated with portions of said support (1) closest to said fork frame (2) and being spaced rearwardly from the portion of said fork frame mounting said oleodynamic cylinder means (5) for pivotally mounting said other end of said pivoted arms (3,3') to said support (1); another end (8) of said oleodynamic cylinder means (5) being pivotally connected to one of said two pivoted arms (3,3') between components of said first and said second means (4,4') mounting said one arm of said fork frame and said support, said oleodynamic cylinder means (5) with its ends (7,8) being disposed in a plane extending substantially transverse to the direction of movement of the tractor, said plane being interposed between the components of said first means (4) and the components of said second means (4'); and feeler means operatively associated with said oleodynamic cylinder means for sensing obstacles and for actuating said oleodynamic cylinder means to exert a force on said one of said two pivoted arms (3,3') in a direction substantially transverse to the direction of movement of the tractor.
