In Field Bale Size Calibration (Channel 028)

    Make a bale and tie or wrap.


  2. Before ejecting the bale, note the monitor-controller display for the bale size or diameter setting.

  3. Eject the bale and compare the actual size of the bale to the monitor-controller bale diameter setting.

    To check the actual bale size, measure the bale horizontally and vertically on both ends. Add the four measurements together and divide by four to determine the average bale diameter.

  4. Make another bale the same size as the previous bale as indicated by the monitor-controller. Wrap it and disengage the PTO.

  5. Do not eject the bale.

    Access Channel 028 on the BaleTrak™ monitor. The display size is shown.

    The monitor initially shows the calculated bale size.

  6. To match the measured size of the bale, adjust the displayed size with the PLUS or MINUS keys. To record as the actual bale size, press the PLUS or MINUS keys simultaneously. To confirm that the size has been recorded, the monitor beeps.

  7. Repeat the procedure as necessary.

A - Bale Diameter Sensor

B - Solenoid Valve

The BaleTrak™ Pro or Plus system uses an optional Variable (Soft) Core feature to lower the core density of the bale, or can improve the bale starting in long, stiff, cane-type crops. This feature uses the monitor-controller in conjunction with the bale diameter sensor (A) and solenoid valve (B) on the tensioning control valve to reduce the hydraulic pressure at the rod end side of the tension and gate cylinders.

The diameter of the soft core can be adjusted 81—142 cm (32—56 in) and is set by entering the desired core dimension into the monitor-controller.

The conditions set by the operator revert to the initial settings when the monitor-controller is reset. The initial setting for the variable core is 91 cm (36 in).

Pushing the Variable Core Diameter button on the monitor-controller energizes the variable core solenoid. The energized solenoid routes the oil from the rod end of the tension and gate cylinders through the low pressure relief valve, then back to the base end of the tension and gate cylinders. The lower pressure allows a looser bale to form initially.

When the bale size reaches the variable core diameter setting (preset by the operator), the monitor-controller de-energizes the solenoid. At this point, oil from the rod end of the tension and gate cylinders are routed through the adjustable pressure relief valve, then back to the base end of the tension and gate cylinders. Bale formation is then completed at the higher relief pressure. The higher pressure forms tighter and denser outer bale layers.

The tractor selector control valve lever must be in the neutral position. If the SCV lever is in the float position, the variable core feature does not work.
