Jul 26, 2009 · All the 17A's are oil clutch and although the engine displacement is the same the bible (rack setting charts) is quite clear on the horsepower ratings. Don't see how they can use the same Nebraska test as the one is dated 1940 and the 17A came out in 1954. Also on production I show the 17A ending in 1961 and the 47/48A coming out in 1962.

Jan 15, 2019 · Replied by rmyram on topic just bought a D7 17a sprockets were probably replaced at one point with new rings, they would cut the sprocket spokes and weld a new ring on so you didn't have to completely dissassemble the final drive when replacing the undercarriage.

Jan 8, 2010 · Have a look at the S/N above the pony motor transmission. If you cant find that either just post a pic and we should be able to workout what it is. A late 50's model would make a D7 17A [ "C" or "D" series ]. D7C weighs 26930lbs bare operating weight. D7D weighs 27230lbs bare operating weight. Cheers Billy
