Note – After you have determined the optimal values for a particular plow series, such as Liebrecht 5'
plow, it is very likely that you can enter the same measurements, offsets, and height gain values for other
plows of the same series. With a good valve calibration for each plow, you should be able to get each
subsequent plow running very quickly.
Determine the pitch offset
Note – It may take some time to determine the proper pitch offset of a plow accurately.
Without a correct pitch offset, the system will most likely attempt to maintain the design slope and
drive the plow above or below the optimal depth.
All cantilever plows must assume an angle that is slightly tipped up in order to maintain depth
against the immense down-pressure being applied by the soil that is being displaced. If the boot
traveled through the soil with an even attitude the plow would progressively plow deeper as it was
pulled through the soil.
After the pitch offset value has been determined, the value should only change as the tip begins to
show considerable wear.
Note – Before completing this process, ensure that the system drives to a consistent depth. This depth may not
be the optimal depth, but it will ensure that the hydraulic system is operating well. Once you are certain that
optimal performance has been achieved, you may begin the process of determining the proper pitch offset
with consistent results.
1. Engage the plow on a newly surveyed section line in soil that has been undisturbed.
2.
Allow the system to drive the vehicle to a consistent depth and then begin entering a positive
Pitch Offset value in the Implement tab. Enter values in 0.50% increments.
Note – It may take 1-2 lengths of the boot for the system to fully recognize this offset.
3. Continue the actions in Step 2 until you are within a few hundredths of optimal depth.
4. Allow the system to drive along the entire section line. Ensure that the system continues to be
consistent through any transitions that are found in the current section line.
5. When you believe the system is running with the highest accuracy possible, survey another
new section line. Allow the system to drive the entire line.
6. Repeat Step 2 through Step 4 until the system gives a consistent result. Note the pitch offset
value you came up with and reset the run screen offset back to 0.00%.
7.
At the Measurements screen, enter the determined Pitch Offset value.
Note – Once determined, this value should only change once the tip begins to show signs of
considerable wear
