Hi, the front end and loader look like a 406. I have one that's all fixed up but blew the torque converter/flywheel plates the first time we used it. There should be a metal tag on the front right side of the tractor frame.
The looks are simular. I think yours is a newer model. I have determined that mine is a MF "Work Bull 303". MF started producing the "Work Bull" line in about 1958 through the mid to late 1960's i think. The loader atachments look the same.
Thanks for the great pictures of your tractor. I just finnished loading about 100 tons for sand over the last 3 days with my 303. mine is working great...but has a hydraulic leak at the control valves for the bucket.
Nice 303,, very tuff tractor. I also have a MF 406 & really would like to talk with above 406 owner. I am slowing stripping paint to get a new coat on it. Mine is beat up but everything works & motor runs great.
