E - Target Depth and Wand Position Graph:
The Target Depth is the depth that the system actively tries to make the lifter wheels dig into the
ground. This number is displayed on the main screen between the two blue wand position bar
graphs. It is important to note that this number does not represent the exact number of inches the
lifter wheels are digging into the ground. While physically adjusting the height of the wands on the
machine can make this number very close to that of the inches into the ground, this number is meant
to just be a scaled reference number. Upon initial use, and periodically throughout harvest, the actual
depth of the lifter wheels should be looked at in a dug row to verify a satisfactory depth.
The target depth can be changed in a few different ways. It can be changed by selecting the plus and
minus icons to the right of the bar graphs. This will change the depth in increments of 0.2 inches. In
certain configurations of the joystick, the joystick can be used to change the depth. See joystick sec-
tion for more information. Again, this will change the depth in increments of 0.2 inches. There are
also two softkeys that will raise and lower the depth in increments of 0.2 inches (Figure 13
- 10 and 13 -
11). The last way to change the target depth is by directly selecting the target depth number, which
will cause a pop
- up keypad to appear and a number can be manually entered in (Figure 13 - 12). The
depth can also be changed from the settings screen as well.
On either side of the target depth number is a bar graph that shows the instantaneous reading from
the wands on the front of the machine. While harvesting, these bars will move up and down with the
wands as they travel over the ground. While there will be lots of movement and spikes, you want to
see that the bars are close to your target depth, which shows that the system is working correctly and
always working to achieve that target depth.
