Ive got a 36" Metro that i purchased at the beginging of the season. It worked good for awhile, but i soon started have problems with the belts that drive the wheels coming off the pulleys. I made adjustments to make the belts tighter, but then it doesnt stop or turn well. Also, when u change the tension to keep it from falling off, it rolls in park. Let me know what i can do to make it work like it supposed to.
