Pickup of an agricultural machine

A characteristic feature of the present invention resides in the fact that in the pickup of an agricultural machine, incorporating a pickup-and-conveying mechanism driven from said farm machine and held to a frame which is articulated to the machine and rests upon the ground by the support wheels thereof, a grate composed of a beam carrying levers rigidly fixed at the beam ends and of a number of rods fitted into the holes in the beam so as to be cantilevered thereto, said grate being articulately suspended from said frame above the pickup-and-conveying mechanism, adjustable limit stops made fast on said frame and adapted for the beam levers to rest against, relieving links carrying elastic members and held with one of their ends to agricultural machine, provision is made for a number of cranks rigidly fixed on the grate beam, the journals of said cranks being connected to the other ends of the relieving links and being so arranged that the line of action of the relieving links establishes a moment effective for forcing the levers against the limit stops.
