I've owned several Massey tractors over the years. I had a MF1643 for 4 years and approximately 445 hours. I now run a MF1754. IMHO, the loader on the MF1643 was not as powerful as the loader on my MF1240. My comment is based on the MF1643 not being able to pick up and move the the same rocks, logs, etc..., that my MF1240 could easily. As an example, I have a relatively large rock that I had placed with my MF1240. I decided to relocate it using the MF1643. It did pick it up and move it, but not easily. Tractor was definitely struggling with the load. In comparison, to test the MF1754, I picked up that same rock and moved it easily. Doing loader work moving gravel and pavers with a heavy
ballast box hanging off the back, the MF1643 always felt to me like it was struggling. In comparison, my previous MF1240 and current MF1754, did/do the same work with ease. Had my dealer check the MF1643 tractor a couple of times and they said it was fine. The overall performance of the MF1643 or lack there of was one of the main reasons why I moved up to a MF1754. Just my 2 cents. I know there are individuals on this site that really like their 1600 series tractors. Hopefully, they will post so you get more information. As a note, my MF1240 and MF1643 were geared tractors, my MF1754 is a hydro.
Obviously, these are my opinions.
Cons:
I was not a fan of the clutch. To me, it was a sloppy clutch (inconsistent feel) after it got hot doing heavy work. Didn't like the powershuttle setup.
Did not like the seating arrangement and cab felt small.
Always felt down on power for a 43 hp tractor which included the loader.
Hydraulics were always jumpy.
Pros:
It was good on fuel. Burned around 1 gallon of diesel an hour pretty much no matter what I did.
Heat and AC was good. Cool in the summer and warm in the winter.
