I am up to 11 tractors now, all of them work on the farm.

1950 MM ZAU
1962 MM M-5 narrow front
1963 MM M-5 with loader
Massy 135 diesel
1978 IH 684 diesel
1968 Oliver 1850 Cummins re-power
1969 Oliver 2150 MFWA Cummins re-power
1971 Oliver 1855 Loader Cummins re-power
1974 Oliver 1655 diesel narrow front canopy
1974 Oliver 1655 Cummins canopy
1975 Moline G-1355 fender tanks, canopy, diesel

And always looking for more, need another MFWA tractor next.
