I was mowing between my dump trailer & a car with my 3 week old X739. I made a sharp left turn to mow in front of the car. I forgot that the rear of a 4 wheel steer swings to the right when making a sharp left turn. The rear fender caught the front edge of the dump trailer bed & left about a foot long scratch in the right fender. I was lucky that it did not crease the metal.
I was able touch it up well enough that I know it is there, but most others will not see it.
