Slope Operation Screens
Use the up or down arrow key to change the default setting for the specific mode selected. Each time the arrow is
depressed, the setting will change by 1.0% in the direction of the arrow (up arrow increases the setpoint and down

next screen for the next adjustment. After the Aggressive Slope adjustment, press OK and you will be returned
to the Neutralizer Setpoint Level Setting main screen.
The Level Operation setting cannot be set below the brake point (0% offset) or above or equal to the Moderate Slope setting.
The Moderate Slope setting cannot be set below or equal to the level setting or above or equal to the Aggressive
Slope setting.
The Aggressive Slope setting cannot be set below or equal to the slope setting or above the maximum
allowed setting.
If Reset is selected, the values are changed back to the default calibrated values.

Fuel Economy Mode
The Fuel Economy Mode Menu allows the operator to select the engine rpm at which the transmission shift points
occur, thus better matching the machine to application requirements.
Transmission Settings: Fuel Economy Mode Screen
The Fuel Economy Mode screen shows which mode is currently selected and also allows operator to select either of following
three modes:
Economy Transmission shifts will occur at lower engine speeds (1,3001,500 rpm). This mode is the
most fuel efficient setting and will improve shift quality (operator comfort). In load and carry applications,
lower rpm transmission shift may help reduce material spill.
Midrange Transmission shifts moderately at engine speeds (1,6001,800 rpm). This is the recommended
position for many operations.
