The 3720 has met all of my expectations. I bought it to replace my very reliable Kubota L3600, because I needed a tractor with a large snow blower and a cab. It used to take about 3 hours to clear me driveway with 10" of snow or more.
Since I have purchased the new tractor, I have used the 3720 with the snow blower 2 times and each snow fall was just 8 to 10 inches. And I say only, because this tractor makes it feel like it is just no challenge at all. Oh well, next year maybe. The heated cab makes it even more fun, to be outside in 12 degree weather with just a light sweat shirt. The whole driveway now takes 30 minutes to clear with the 59" blower. So of course I go looking for more to do.
