hello i have a troybuilt pony 42 inch mower. accidently let the blade hit the edge of the street. blade was bent badly so i replaced the blades with brand new ones. well now the cut looks horrible, so i adjusted the deck per the owners manuel and no real difference still uneven cut. the blades do line up in the center and i have even distance side to side from the ground. tire pressure is right on. my guess is i have either bent the deck and or spindles. anyone have any thoughts before i start buying parts . thanks
