I am looking to buy a zero turn for the farm i work for. we will be mowing about 5 acres with it. someone had bought a stiener but it is junk! so i am looking to spend 10000 + or -. hopefully -. 50 ish inch deck looking for durability due to 7 diffrenet people that will be mowing with it. I like the exmarks and kubota's curious about the john deeres have four of the tractors so it would match and we have a dealer 5 miles away. any suggestions?
