Hi. I,m mowing with my Massey 1643, industrial tires, it weight +- 4400 pounds. When mowing I take off the loader. Always use the 2wd because on 4wd on sharp turns, the front tires are damaging the turf (try to avoid sharp turns even on 2wd and on dry land it is safer for your turf). If your only use is mowing, turf tires would be a good choice. Good luck:thumbsup:
