Nice looking tractor. A suggestion - air pressure in rear tires might be a bit high. Does not appear that there is full contact across the entire bar tread. Check owners manual. I run 15psi to get full bar contact. Enjoy........
Nice tractor, congrats. Make a mental note to lower ROPS before backing into the garage, I forgot the other day but, fortunately, was moving very slowly and heard it contact the trim above the door.....tiny little divot.
AH, ha - - you are perhaps the first to get a new tractor with the new R-14's. You are probably correct - your OM may not list these tires. You might email the manufacturer and see what they say. Perhaps the dealer got some literature from the manufacturer on these new tires.
