3pt 2 Bottom Moldboard Plow Identification

[Marengmech]

Hello,

Trying to identify this plow so I can try and figure out how the handle thays bent into a "U" is supposed to work. Anyone have any ideas? Has super Chief x series bottoms, and after a little research, leads me believe its an old IH plow. Maybe a 420? Im probably wrong. Thought i would reach out and see if somwone here could steer me in the right direction. Thanks in advance

Douse it rotate the rock shaft to angle the plow up and down at an angle to start a new furrow, level it side to side?

That's a landing lever to do what Paul said. I don't recognize that plow. A 420 has a one-piece square box for the 'backbone' and a 209A is a truss-frame lacking that 'backbone'. People have been known to make a bottom from a manufacturer that still has readily available wear parts fit a plow from a manufacturer whose wear parts are obsolete.

Paul is, unfortunately, repeating a very common misnomer. The plow is leveled side-to-side by changing the length of the tractor lift links. For starting out, you're supposed to lengthen the right-hand link, but not everyone does this. Timmy is partially correct- that is the landing lever. The plow bar with a hitch pin at each end should wind up roughly vertical, with the right pin 'down' and the left one 'up' so in regular plowing, when the tractor is tipped over to the right, the tractor lift links can be about the same length.

Moving that lever will tend to move the rear of the plow right or left so it trails correctly. Lever forward makes the plow pull toward the land.

So it actually rotates the 3pt beam fore and aft, not so much up and down, based on where it is indexed?

Interesting.

Most of my plowing has been trailer trip plows and 2 point plows, not so much experience with a 3 pt I guess.

It's all coming back to me now. I last plowed with a JD 416 3-point plow on an MF 65 27 years ago. Semi-mounteds since then.

Ok. I will have to get a new lever or straighten that one. And gear up a spring mechanism. And a piece for setting it. I got the plow for $10 at an auction. So worth it to put a little time and effort into it.

I think it is an IH C26 3pt plow made in IH Hamilton, Ontario, Canada plant, the three bottom version was a C36.
They were made for the B-250, B-275, B414 tractors with 3pt hitch. We had the 2 bottom version back in the mid 1950s and used it on JD 420U.
Later bought the C36, 3 bottom version in the early 1960s when Dad bought a B414D. The C26 had ACE bottoms and the C36 had the Super Chief bottoms. As others have said the lever was for side hill plowing as you could adjust the toe in/out of the plow bottom to keep the plow going straight on a side hill.
