F - Hitch Raise and Lower:
The hitch can be manually raised and lowed to adjust the height of the front of the harvester. By rais-
ing the hitch the harvester is raised. The are a number of ways to raise the hitch. On the main screen
there is a picture of the hitch with an up and down arrow that can be used to raise or lower the hitch
(Figure 13
- 3). There are also two softkeys that will do the same thing. The last way to raise the hitch is
to configure the joystick to allow it to raise and lower the hitch.
In all options, the raise and lower hitch function controls the movement incrementally. Each touch of
the button moves the hitch for a certain amount of time. The amount of time is PTO dependent. If the
PTO is not running, the hitch will move for a longer period of time, or further, than if the PTO is run-
ning. If the PTO is not running the hitch will move for four seconds. If the PTO is running the hitch will
move for 0.3 seconds.
While in “ AUTO ” mode, if the raise hitch function is held for three seconds, the system will enter into
an End Row function. Raising or lowering the hitch while in “ AUTO ” mode will cause the system to exit
“ AUTO ” and enter “ Manual ” mode.
G - Rear Axle Max and Min:
The rear axle can be manually raised all the way up or lowered all the way down if desired. There are
two icons on the main screen (Figure 13
- 6) that can be used to achieve this, along with two soft keys
(Figure 13 - 7 and 13 - 8). By selecting the max height icon or softkey, the rear axle cylinders will extend
to the max stroke of 10 inches. By selecting the min height icon, the rear axle cylinders will retract all
the way.
