There is a simple alignment gauge people use for checking that Jason - you can find out what it looks like and how you use it by searching old threads here. The gauge is simply a piece of half inch square rod longer than the mower, with a 5/16 inch screw going through it laterally in a tapped hole. You use the screw to measure whether the reel is the same distance above the rollers on both sides. You also need to check whether the front and rear rollers are parallel to each other in the horizontal, so the mower will sit flat on a flat surface.
