This 1940 D7 was an army cat and is green under the old yellow, has been on the farm here since 1960. Runs OK. has 3T motor and direct hydraulic blade (Dad cut the old linkage cylinder stuff off and put on the hard nose etc.). Rails and sprockets OK. Comes with another D7 7m for parts with a cable unit and cat blade, also a pile of extra parts. What would the 2 of them weigh? would like to get $100 a ton for all.
