  • a pair of elongated and vertically spaced top and bottom rails extending between the inlet and discharge ends of the bale chamber;

    a pair of elongated and horizontally spaced left and right siderails extending between the inlet and discharge ends of the bale chamber; and

    a squeeze mechanism positioned proximate the discharge end of the bale chamber for adjusting the size of the discharge opening of the bale chamber, the squeeze mechanism includinga vertical squeeze assembly including a first fluid power assembly for selectively shifting the top and bottom rails towards and away from one another for adjusting the vertical distance between the top and bottom rails near the discharge opening of the bale chamber, anda horizontal squeeze assembly including a second fluid power assembly for selectively shifting the left and right siderails towards and away from one another for adjusting the horizontal distance between the left and right siderails near the discharge opening of the bale chamber,said first and second power assemblies being at least essentially simultaneously actuatable to simultaneously adjust all four sides of the bale chambers.
