Which steering mode provides only front wheel steer?

The steering mode that provides only front wheel steer is the two wheel conventional method. In this mode, the steering system is designed so that only the front wheels are utilized for steering the vehicle. This is the most common steering configuration found in traditional vehicles and offers straightforward handling and maneuverability, especially in typical driving scenarios.

In contrast, the other steering modes involve varying degrees of steering from both front and rear wheels, which can enhance maneuverability in certain situations but are not reliant solely on the front wheels for steering. For instance, four wheel coordinated mode allows both front and rear wheels to turn in the same direction, improving the turning radius. Four wheel crab mode enables all wheels to steer in the same direction, allowing for diagonal movement. Lastly, four wheel drive refers to a vehicle's capability to distribute power to all four wheels for enhanced traction, but it does not specifically indicate steering functionality. Thus, the two wheel conventional steering mode is the only one that focuses exclusively on front wheel steering.
