9. Press and hold the “learn” button on the switch
box, until the LEARN indicator flashes.

by setting Calibration switch to “OFF”.

(APPLIES ONLY TO PLANTERS WITH s/n A1056S+)
Tractor Right Calibration
11. Put the steering in tractor wheel sensor calibration
mode, by setting Calibration switch to the
“TRACTOR” position.
Note: Do not move the Calibration toggle switch from the
“TRACTOR” position until step 18, or the new
tractor calibration is ignored.
12. Make a complete forward right turn, as tight as the
rig permits, with all wheel in a hard right turn.
Stop.
13. Press and hold the “learn” button on the switch
box, until the LEARN indicator flashes.
Steering Mismatch Risk:
Do not press the LEARN button more than once for each
orientation (right, straight, left). If pressed more than once,
invalid steering data is stored. You must restart the sequence
(see “Errors and Re-Tries” on page 153).
Tractor Straight Calibration
14. Drive straight forward until the entire rig is running in
a straight line. Stop, with all wheels straight ahead.
15. Press and hold the “learn” button on the switch box,
until the LEARN indicator flashes.
Tractor Left Calibration
16. Make a complete forward left turn, as tight as the rig
permits, with all wheels in a hard left turn.
Stop.
17. Press and hold the “learn” button on the switch
box, until the LEARN indicator flashes.
18. Complete the tractor wheel sensor calibration mode,
by setting Calibration switch to “OFF”.
Errors and Re-Tries
If you are unable to complete a sequence, set the
Calibration switch
to “OFF”, and restart the calibration
sequence from the beginning (step 3 for caster or
step 11 for tractor). Do not attempt to start from where
you left off.
If you need to re-try a sequence (for example, you run
out of room to complete a circle or straight run), set the
Calibration switch
to “OFF”, reposition the rig and
begin again.
It is not necessary to re-calibrate caster steering, if only
the tractor steering needs to be re-done.

19. Turn the Ignition Switch to the ON position. DO NOT
START the ENGINE.
20. Put the Steer Toggle switch to the ON position. The
power light on the steering switch box and the LED’s
on the electronic steering module should all be
illuminated.
21. Put the steering in the tractor sensor calibration
mode by setting Calibration switch to the
TRACTOR position.
Note: Do not move the Calibration toggle switch from the
TRACTOR position until step 28 or the new tractor
calibration is ignored.
22. Turn the steering wheel all the way to the right and
hold in this position to simulate a hard right hand
turn.
23. Press and hold the LEARN button on the switch
box until the LEARN indicator flashes.
24. Release the steering wheel. It should return to the
center position.
25. Press and hold the LEARN button on the switch
box until the LEARN indicator flashes.
26. Turn the steering wheel all the way to the left and
hold in this position to simulate a hard left hand turn.
27. Press and hold the LEARN button on the switch
box until the LEARN indicator flashes.
28. Complete the tractor sensor calibration mode by
setting Calibration switch to OFF. Only at this point
are the new calibration values accepted by the
system.
