I have a 4610 MF. Bought new in June of 2015. I have been very impressed with the tractor. An amazing cab. Tons of power and will handle field work with ease. I have pulled a 5-16 plow with it in sod. Made it snort but she was able to handle the job in low range, 5th gear. Went almost 3 mph. Plowing it will suck a little more fuel than that 4708 was, probably around 2.5 gallons an hour. But for the work getting done that is impressive. The only problem I have had was an error code issue with the rail pressure relief valve. My dealer has gotten that fixed to the best of my knowledge. Also due to operator error the cab door got shattered and needed to be replaced. In looking at the 4708 video I actually like the setup of the controls better on my 4610. The only major complaint I have is the cab tends to fog up a bit in the winter weather. It neccesitates me having to crack open a side window and things are fine. Even in todays single digit weather it was still very comfortable in the cab with the window open.
To sum it up, power to burn on this tractor. Reliable. Economical to run. At the time it was also a very reasonably priced brand new tractor. $52k. I would buy this Massey again. I am however going to consider trading this summer again, just to maintain the value and keep a warranty in tow.
I also have a 2615 MF that I am mostly pleased with and a little 1726E that is the most comfortable ride of a tractor of its size that I have ever experienced.
