Just wondering from some of you that have used several brands of ztr's which ones have the best ride? I am hearing alot about the new suspensions like Gravely and the front caster wheels that have some sort of springs. Love my Exmark but If I had a complaint it would be the choppy ride even with the suspension seat. They don't seem to be looking into improving the ride while other's have addressed this issue. The flatless front tires make the ride a bit rougher also but it's a good trade off. I'm not going to trade anytime soon but would like to know how these new mowers with suspension compare. Thanks.
