Abstract: An density control/anchor cable is provided on an agricultural bagging machine for engagement with the material being bagged as the material is forced past the density control/anchor cable into the bag being filled with agricultural material. The forward ends of the U-shaped density control/anchor cable are attached to first and second trolleys which are movably mounted on an I-beam positioned within the tunnel of the machine. The trolleys may be moved towards one another in tandem and away from one another in tandem from a position remote therefrom. One end of the density control/anchor cable may be selectively released from the second trolley from a position remote therefrom, thereby releasing the anchor effect of the U-shaped cable. The movement of the trolleys with respect to one another permits the precise density control of the material being packed.
