Nothing equals a cab in the winter. Question, Is your tractor built by LS? Does Fiat build small tractors themselves? Some will say LOAD REAR TIRES. Unless you perform extensive loader work and do a lot of mowing, It does NOT work for me.
My tractor is plenty heavy for snow pushing and a rear implement is plenty of balance/ballast. You did not state your location, but with our non-existent spring, the mowed areas remained very wet, even into last week. So the extra weight of loaded tires is just not in my interest. Good luck w/ the tractor.
