In my thread the other day somebody else said they weren't happy with how the back tires on these mowers are so wide that they make trimming around trees difficult.  I did some measuring and flipped the rear left wheel around so it's dished in now and that moved the tire in about 2" which makes this mower trim around trees just as good as any other ZTR.  I think if the right tire was flipped it would hit the battery box but most of the trimming is done off the left side anyway.
