I still use my 1966 MF 135 with rear blade that I can angle..it works great with the tires loaded...but (after this year in northern ohio)..I sure miss the tire chains we use to have on it ...it was a little beast then...when I was a kid back in the 70's I use to pull people out every winter for cash...people were amazed what that little massey could do. I am now going to buy another set of tire chains...anybody know where I can get a good set? MF 135 bought new in 1966..never done anything to it but general maintainance..Z145 engine..and still fires right up in -10 cold.we love our little massey.
