I had 1 1/2" spacers on my old BX22, however, I never noticed much of a difference since I don't have my slopes on the property that I would transverse with the tractor. I have another pair that I purchased for the BX23S, however, haven't installed them yet. Presently I am doing all my tractor work with turf tires, however, I am going to be doing some york raking project in the next few weeks, so should I put the spacers on for this type of work or will it make no difference? I am also going to be taking the turf tires off and installing a new pair of R4 tires. These tires are not loaded, however the turfs are. For the best traction in dirt, will the unloaded tires work as well as the loaded tires? I have a pair of loaded R4s from my old tractor and a new pair of R4s that are unloaded that I picked up recently. Which ones will work best? thanks
