    540 rpm Driveline

    A - Sensor Angle

    B - Round-Head Bolt and Flange Nut, M8 x 20 mm (2 used)

    C - Sensor

    D - Clutch Fins

    E - Lock Nut (2 used)

    F - End of Sensor

    G - Clutch Screw

    H - Clutch Yoke

    I - Tie Band

    Install sensor angle (A) using round-head bolt and flange nuts (B). Leave hardware loose, sensor requires adjustment.


  11. Adjust end of sensor (C) 2 ± 1 mm (0.080 ± 0.040 in.) from clutch fins (D) on PTO clutch.

    NOTE: End of sensor is a magnet. Washer or feeler gauge can drag on magnet creating false sensor-to-fin reading during checks.

    • Place a 2 mm (0.080 in.) washer or feeler gauge against end of sensor (C).
    • Advance sensor (C) with washer or feeler gauge toward clutch fins until gauge just makes contact.

  12. To tighten sensor:

    1. With clamp snug against bracket, tight bottom lock nut (E) an additional one full turn.

    2. Tighten top lock nut (E) until slit closes completely, then tighten one additional full turn.

    3. Gently pull on end of sensor (F) to verify it does not move.

    4. Using a 35 mm (1-3/8 in.) wrench, go to left-hand side of baler and turn gearbox output shaft to verify end of sensor clears clutch screws (G) and clutch yoke (H).

    5. Adjust sensor side-to-side by loosening and tightening nuts (B) as needed.

    6. Remove wrench from output shaft on left-hand side of baler.

  13. Verify that sensor is not damaged after tightening nuts.

    • Connect multimeter leads to sensor connector.
    • If multimeter reads approximately 3000 Ohms, sensor is good.
    • If multimeter reads zero, sensor is bad. Replace sensor.

  14. Recheck 2 ± 1 mm (0.080 ± 0.040 in.) clearance between clutch fins and sensor while gently prying PTO clutch forward to simulate PTO driveline thrust loads.

    Hold PTO clutch forward and perform the following:

    • If 1 mm (0.040 in.) gauge does not pass between clutch fin and sensor, repeat Steps 4—6 to obtain proper clearance.
    • If 1 mm (0.040 in.) gauge passes between clutch fin and sensor, clearance is acceptable.
    • If 3 mm (0.12 in.) gauge passes between clutch fin and sensor, repeat Steps 4—6 to obtain proper clearance.

  15. Tighten tie band (I) around wiring harness connector and secure to bracket.

  16. NOTE: Not used on 459 or 559 with a Regular pickup.

    NOTE: PTO and pickup sensor values are set at factory.

    A - COUNTER Key

    B - NUMBER OF WRAPS Key

    C - PLUS Key

    Verify PTO and pickup sensor values are activated using the following procedure:

    • Turn tractor key to ON position. Do not start tractor.
    • Press and hold both COUNTER key (A) and NUMBER OF WRAPS key (B) while turning monitor-controller ON. CH201 must be displayed.
    • Release both keys. Baler model is displayed.
    • Press and hold COUNTER key (A) and press the PLUS key (C) until CH204 is shown in the display.
    • Release COUNTER key (A).
    • Press PLUS key (C) to change display to 540 PTO speed.
    • Press and hold COUNTER key (A) and press the PLUS key (C) until CH205 is shown in the display.
    • Press PLUS key (C) to change display to 310.
    • Press and hold COUNTER key (A) and press the PLUS key (C) until CH206 is shown in the display.
    • Press PLUS or MINUS key to change display to 24 (number of fins on slip clutch).
    • Press and hold COUNTER key (A) and press the PLUS key (C) until CH207 is shown in the display.
    • Press PLUS or MINUS key to change display to 10 (number of teeth on tone wheel).
    • Turn monitor-controller OFF.
    • Turn tractor key to OFF position. Remove key.


  17. NOTE: The twine, net wrap, slip clutch alert, and optional variable core features will not operate correctly unless the model number displayed on monitor-controller matches baler model number.

    A - COUNTER Key

    B - NUMBER OF WRAPS Key

    Verify correct baler model program using the following procedure:

    • Turn tractor key to ON position. Do not start tractor.
    • Press and hold COUNTER key (A) and NUMBER OF WRAPS key (B) while turning monitor-controller ON. CH201 must be displayed.
    • Release both keys. Baler model is displayed.
    • Press PLUS or MINUS key to change to desired model.
    • Turn monitor-controller OFF to enter setting into memory.
    • Turn monitor-controller ON to verify baler model number. Baler model is displayed for approximately 2 seconds. If displayed baler model number is incorrect, repeat procedure.
    • Turn tractor key to OFF position and remove key.


  18. To check sensor output and verify proper operation, use the following procedure:

    • Start tractor, operate at low, but stable, rpm and engage PTO.
    • Press and hold COUNTER key while turning monitor-controller ON.
    • Continue to hold COUNTER key and press PLUS key until CH016 appears in the digital display.
    • Release COUNTER key and PTO speed is displayed. This speed readout must be stable and not vary by more than 5 rpm.
    • Press and hold COUNTER key and press the PLUS key until CH017 appears in the digital display.
    • Release COUNTER key and pickup drive speed is displayed. This speed must be stable and not vary by more than 5 rpm.
    • If there is a variation in either sensor output, shut off tractor and remove key. Adjust appropriate sensor closer to clutch fins or tone wheel, but not closer than 1 mm (0.040 in.). Then recheck.
    • With tractor PTO speed of 540 rpm, pickup sensor must read approximately 310 rpm. If pickup sensor rpm is greater than PTO clutch rpm, then orange and brown wires are reversed at the harness connector.

      Example of a problem: Monitor displays slipping. (See SLIP CLUTCH ALERT in Troubleshooting section).

      If there is a variation in this output, readjust sensors closer to tone wheel or clutch fins.


    NOTE: Not used on 459 and 559 with a Regular pickup.

    Turning PTO Speed Sensor ON and OFF:

    • PTO speed sensor can be turned OFF or ON by accessing channel 204.
    • Feature can be turned ON by changing value to 540 rpm.
    • Entire slip clutch alert feature can be turned OFF by changing value to 0.

    NOTE: Not used on 459 and 559 with a Regular pickup.

    Turning Pickup Speed Sensor ON and OFF:

    • Pickup rpm sensor can be turned OFF and ON by accessing channel 205.
    • Feature can be turned ON by changing value to 310 rpm.
    • Pickup rpm sensor can be turned OFF by changing value to 0.
    • Turning OFF the pickup sensor on channel 205 and turning ON PTO sensor on channel 204 still allows automatic speed compensation during wrapping cycle.

  19. IMPORTANT: Tie band wire harness to hoses, as needed, to keep harness away from rotating slip clutch.

    IMPORTANT: Cap screw heads (B) must lead as driveline rotates counterclockwise when looking toward rear of baler.

    NOTE: Adjust cap screws evenly.
