Which gear should you use in order to start moving a tractor on an icy surface?

Explanation

Correct answer: The gear which requires you to apply the lowest possible driving force of the wheels.

On an icy surface, wheel grip is significantly reduced, therefore it is crucial to avoid wheelspin. Applying too much driving force, which is characteristic of low gears (e.g., first), will cause a loss of traction and make the wheels spin on the spot. Selecting a gear that provides the minimum force needed to move off smoothly (this will often be second gear) allows the vehicle to be set in motion gently without breaking traction.
