I just bought a one owner MT 372 with 450 original hours in perfect shape with deck mower and land pride scraper blade for 2k. So far it is an amazing little machine. I am going to be using it to grade/groom horse arenas and snow removal around the house as well as lawn. It has a set of turf tires but am thinking about adding ag tires any body have a good source online? we have heavy clay around here and those tires seem to slip, would chains make a difference?
