When backing a tractor under a trailer, which gear should you use?

When backing a tractor under a trailer, using the lowest reverse gear is optimal because it provides maximum control and torque. This gear allows for precise adjustments to the speed of the vehicle, which is crucial for aligning the tractor to the trailer correctly. Maneuvering in reverse can be challenging due to visibility limitations, and the lowest gear helps to minimize the chances of oversteering or misjudging the distance.

Using the lowest reverse gear also helps to ensure that any adjustments while backing up can be made gradually, allowing the driver to respond to any slight directional changes needed to achieve a secure connection with the trailer’s hitch. In contrast, higher reverse gears might allow for faster movement, which can lead to mistakes or accidents during the critical backing process.
