Model 83 - 3 POINT PLOW

This plow seems taller than my other plows. My manual doesn't mention a high clearance but is definitely taller than my others. Is the stub beam longer on the high clearance? Did Allis make differant height plows in the 80 series?

Jeff, please tell me how to post that photo the way you did that. Hannah is ready to kill me! Thanks Tracy Martin

I've not seen any mention of tall vs short shanks in the plow frames book I have. Its available on line from http://www.grandpastractor.com/phpBB3/index.php You might look to see if its shown under 9000 in that book. I didn't think 83 would have the top beam, but I could be wrong. I don't have that parts book at the computer tonight. There is a spring trip shank shown separately that the description says for model 60 and 80 plows, separate from the spring trip shanks shown in the model 80 plow frames. Look at the spring trip arrangement as it could have changed with time.

The truss bar on top of the plow frame was standard on a 4-bottom plow and was optional on the 3-bottoms. My brother has a similar plow that would barely clear the ground on his D-17IV. He switched out the stub beams with some from a 9000 plow which were about 3" shorter.

I can't tell relative shank length from the parts book. But the trip is typical of later rather than earlier spring trip shanks, like applied to the 9000.

Longer shanks take a stronger trip mechanism but slow down plow plugging in corn stalks. I've come to like a semi mounted plow on a long frame like my 2000 over a closely coupled three point because the greater front to rear spacing is harder to clog. Some IH 720 and 740 have much longer shanks to raise the beam further and have a great reputation for handling corn stalks very well.

Nice plow Tracy - we have an 83 series S/C plow with the extra bar on top plus a gauge wheel.
