I ve got 13.5-16.1 Firestone and 25x8.5-14 turf saver tires on my LK3054. The problem I'm having is the tractor leaves ruts unless the ground is completely dry. Any suggestions what I can do or switch to that would help prevent ruts. The tractor has a FEL and usually has a backhoe, 50 gal sprayer or 60" aerator on the rear.
