Hydraulic Drive Operation
27. When the sample run-time has expired, the motor
stops, the indicator above the ENGAGE button goes
out, and the console displays the estimated sample
generated (based on actual motor performance,
which may vary slightly from calculations).
The number display is normally very close to the
sample size entered at step 19.
28. Press the OFF button on the console.
29. Return hydraulic motor circuit lever to Neutral.
30. Exit the tractor cab. Return metered seed to seed
box.
If you see the screen at right, the console has detected
an error. The most common problem is that motor
rotation has not been detected. Check:
• all cables connected
• hydraulic fluid supply to motor
This screen is a normal and harmless condition if you are
operating the console disconnected from the drill.
Full Calibration
Make sure the seed meter cups are full, and seed can
flow at initial motor rotation. To prime the cups, see
page 38.
31. Turn the console on with the ON/VR button. Check,
and as necessary, repeat step 1 through step 18.
32. Enter the amount of seed you want to measure. This
should be at least
1
4
pound (0.1 kg). Press
FUNCTION button to advance to next window.
The amount shown at right is from the example
estimate at step 2.
