I just couldn't see how 7 horse is worth almost $2000.00 list price. Every quote I got was at least $1500 dollars more for the 3720. Its the same tractor with the addition of an intercooler and maybe some injection work. My dad owns a 955 and I have a good friend with a 4410. The 4410 has never had any power issues due to the fact that all these new tractors have at least a three range HST. If I have power issues, I have access to equipment that will make these things look toys. I wanted to go big enough to have the turbo, but didn't need the biggest. The 4720 is awesome and maybe I'll trade up someday. In three years, you know John Deere will come out with a thirty series, or some kind of improvement to the twenty series.
