I have a 2005 Gravely 260 that I use for my three acre lawn. I have had trouble with the turf tires slipping when trying to do turns that require fast movement from forward to reverse as well as on the 12-15 degree slope around my pool berm. They shocked me a few days ago when they would not hold the incline on dry grass at a relatively slow speed. I almost went into the lilac bush at the base of the berm. Is there a better tire available for use on these things? I have seen the Dixie Choppers in action and they are run at a much faster speed and sharper turn without problems.
