Am looking at getting a F 935 Diesel front mower (72") with 2200 hrs on it for $3,000. It sounds and runs good and does a good job mowing on my test drive. I have been mowing with a Massey 1020 MMM (60") and have never been impressed with the quality of cut. My yard is fairly rough riding even on the tractor and am concerned about how much difference there will be going to the smaller wheels on the 935. I mow about 3 - 4 acres and can usually be done in around 3 hrs. Will I save time with the wider cut or lose time by possibly having to travel slower? Any one out here,have experience with the ride of these units?
