The hydraulic lifting device includes a pivotable element carried by the machine; a beam-shaped element hingedly connected at one end to the feeder and at the other end to the pivotable element; and a cylinder hingedly connected at one end to the beam-shaped element and at the other end to the pivotable element such that extension of the cylinder causes the pivotable element to pivot and a height of the feeder to change.
