The promos of the multi-starrer film, Heroes have begun flashing on every channel and one can see Preity Zinta driving a tractor in one shot. Not many are aware that Preity was petrified of driving that tractor when that sequence was to be shot.

A source informed, "Preity's character in the film is of Salman's wife who is shown as a simple farmer who later goes on to join the army.

She features in a no make-up look in the film. It was very important for her character to be shown driving the tractor easily as it would lead authenticity to her character. But the problem was she was simply not ready to do that.

The director of the film, Samir Karnik kept on insisting, while she kept on putting her foot down. Until, Salman came to know about it. Salman then came upto her and assured her that in just two days he would train her well to drive the tractor perfectly.

Preity agreed and then actually in two days time, she was driving the tractor in the Punjab fields like a pro!"

How did Salman know to drive it so well? The Khans have a huge farm in Panvel, near Mumbai and Salman often visits it. They have a tractor there and he for fun rides it around.
