According to the present invention an agricultural machine for forming a round bale of windrowed fibrous material comprises a displaceable chassis carrying spaced apart side plates defining the width of a bale-forming chamber, a pick-up device located towards a forward end of the chassis and adapted to pick-up fibrous material from the ground and to discharge the fibrous material on to a carrying surface, which extends generally horizontally, of a first, fixed position belt conveyor defining the bottom of the chamber, and having a head end adjacent the pick-up device and a return end remote from the pick-up device, and serving to carry the fibrous material away from the pick-up device, and a plurality of additional belt conveyors each having an active surface adapted to co-operate with the carrying surface of the first, fixed position belt conveyor in the forming of a bale by the rolling of fibrous material, at least one of the additional belt conveyors being movable by having one end pivotably mounted, so that its other end is arcuately movable from an inner position to an outer position as the bale diameter progressively increases, means to urge the movable conveyor(s) towards the inner position and means to displace at least one of the belt conveyors whereby a finished bale may be discharged from a rearward end of the machine.
