What should be done to verify tow bar alignment before moving to prevent binding?

Explanation:
Ensuring tow bar alignment before movement is essential to prevent binding as you begin towing. When the tow bar is aligned, the connection sits square and the load travels along the intended path, reducing sideways forces that can twist or bind the system. Visually inspect alignment first. Look for the tow bar sitting square in the coupling, with the pin fully engaged and safety devices in place. There should be no visible offset between the tow bar and the nose gear connection, and the arms should not appear twisted or strained. A clean, centered appearance at the connection point is a good initial indicator that everything is mounted correctly. Next, verify the nose gear pivot. The nose gear should pivot smoothly and freely, with the tow bar pivot point aligned to the steering axis. Any binding or rough spots in the nose gear pivot can transfer into the tow bar, creating off-axis forces that lead to binding when you move or steer. Finally, perform a light test pull. Move a small amount to see if the tow bar stays straight and tracks with the tractor without pulling to one side or binding at the connection. This gentle check confirms that the system will remain aligned under light load, and if there’s any deviation, you can re-center and recheck before proceeding. Relying on driver judgment, jumping into a test drive, or skipping checks if steering feels fine can miss subtle misalignments that only show under load, risking binding or damage. The combined visual check, nose gear verification, and a light pull provides a controlled, proactive confirmation of alignment before moving.
