Just got to use the new Wright Stander today. I bought the 36 fixed deck. Every lawn that I cut had deep tire tracks, not ruts tire tracks. The cut is great and there are no other problems. I havent checked the air pressure I figured the dealer has it set up correctly. Is this common with the standers ? Is there anything I can do to fix this. None of my other mowers do this, Please give me your thoughts !!!
