Installing Orifice for Tractors With Low Hydraulic Flow (592 Only)For tractors with hydraulic flow less than 25 L/min (6.5 US gal/min), the gate may close before the belt tension arm returns. This may result in belts being pinched between the lower gate roller and axle tube. To correct this situation, install orifice which is available through your John Deere dealer.
Clean fittings and valve area before disconnecting hydraulic hoses. Remove cap screws (A). Bale density control valve can then be lifted for access to lower hydraulic fitting. |

CAUTION:
To avoid injury from escaping fluid under pressure, stop engine and relieve the pressure in the system before disconnecting or connecting hydraulic or other lines. Tighten all connections before applying pressure.
