Abstract

Improved arrangement in agricultural machines for removing tubers, of which comprise a frame provided with a pair of wheels of adjustable height, and means for hooking to a tractor tractor; equipped with said frame with operating elements, or baskets, which oscillate horizontally thanks to a pto transmission of the tractor itself, characterized in that the transmission from the power take-off arm of the tractor to the oscillating baskets is constituted with an eccentric connecting rod, which through two separate arms is directly related to each of the motor coupling groups of the end baskets, linking another arm to one of these groups with the motor group of a third central basket, with the particularity that the articulated coupling of each one of said braced arms with the corresponding group to which the transmission is effective is constituted by an oscillating bearing, said eccentric connecting rod being constituted by a plate whose faces protrude from each unshackled axis, one of which remains coupled to the pto arm, while the other has a couple of bushings mounted xcentrics on which the articulated coupling of the respective tie arms becomes effective, said eccentric bushings being adjustable in their relative angular positioning, in the possibility of a variable transmission eccentricity.
