Thanks to Salman khan, for once and for ever Priety Zinta wiped off a challenge that was proving to be difficult to deal with. The B-Town cutie was on a hard time as for a particular scene in the forthcoming flick 'Heroes', she was required to drive a tractor. As Priety started to feel the whole learning process tiresome, the savior came to the rescue. Within two days, Salman Khan passed on his expertise and made the actress a master in driving tractors. The muscle man is quite adept in using the big vehicles as he has a tractor at his farm house. Preity Zinta plays the role of Salman's wife in 'Heroes'.
