Figure 210 displays the TMC hitch steering screen with the manual mode feature. This function allows the operator to hold the tractor’s three-point hitch in a desired lateral position, adjusted within the TMC display.

Usage Recommendations

• Select the manual mode within the TMC display to activate the feature.
• Ensure the power take-off is disengaged.
• Keep the raise/lower switch in the neutral position.
• Capture the vertical hitch position to the lever position.
• Capture the steerable hitch position.

Operators can modify the Steer Offset parameter within the TMC to move the hitch from the full left to the full right position. Capture the steerable hitch by manually adjusting the Steer Offset to the current position or by raising and lowering the hitch.
