Picked up a Toro Proline 52" w/floating deck and a Toro Tru Track sulky made for a fixed deck (model 30109). Can someone tell me what the difference is between the sulkies made for a floating deck and those made for a fixed deck? From what I can see, it's just the holes in the brackets and the spacing of the brackets. Is there any reason why I can't use this sulky if I get it fitted/attached correctly? Do I need more than 1 bolt on each side attaching the mower and the sulky? Also, what's the difference between the Toros w/a fixed deck and mine w/a floating deck?
