7.9 Active Height Control (AHC)
Active Height Control is available on 00 or 50 series 12 row defoliators. When used properly and set
correctly for varying conditions, AHC can automatically level the defoliator by using rear sensor bas-
kets to measure the average heights of the beets during the AutoLevel functionality.
7.9.1 Setting up AHC
Before operating AHC, follow these steps while observing the aforementioned safety instructions in
section 2:
1. Ensure flow is running to the AHC hydraulic block in the proper direction. Set to 7 GPM initially
and adjust higher or lower based on preferred response timing of adjustment changes in the hy-
draulic cylinders.
2. Ensure your screen has power and is connected to the main harness.
3. Pressing “ End Row ” on the home screen should now raise hitch cylinders to 75% full stroke and
raise rear cylinders completely. If “ End Row ” does not raise the cylinders, try reversing the flow
and/or ensuring hydraulics are plumbed correctly.
4. Raise the rear AHC baskets. These can be plumbed by itself, plumbed in parallel with the rear
row finder, or connected to the scalper bar.
5. Once rear baskets are fully raised, press “ Calibrate System ” on the options screen (wrench sym-
bol). This should set the “ Calibration ” sensor on the home screen to be green.
6. If your desired settings are unknown, good settings to start with are 50 for the “ Rear Height ”, 60
for the “ Hitch Height ”, and 0 for the left/right offset found in advanced options (wrench & gear
symbol). These settings are typically higher than usual and will allow you to lower or raise your
defoliator into the proper position.
