IH 37 disc hitch?

Yesterday I posted a picture of my IH disc hoping to determine the model # of it. Several of you thought it might be a model 37 except for the unusual hitch. I decided to start a new post with a better picture of the setup here.
The picture in my below post was when I brought it home; there was no cylinder on it yet. Here is a close up with the cylinder installed. The rod and linkage raises the front hitch as you raise the wheels keeping it more or less level when raised. Certainly doesn�t look homemade to me. Could it be some kind of optional hitch on a model 37? I couldn�t find any remnants of a model # anywhere on it. Was it actually stamped into it anywhere? How did a model 370 differ from the 37? I can�t seem to find any info on a 370.
I also looked around on the net last night and found another picture, which was labeled in the ad as a model 37. Nothing official about the # though. It has the same rod and linkage but appears to be missing the actual hitch. Thanks for the help!

• Another model 37 ?

Tim -
Like others said your disk appears to be a Model 37. Mine looks very similar to yours. Pic is when I first got mine. Busted disks and all we went to work :) Come-a-long on the back was to raise and lower since my Oliver did not have hyd. controls nor the control rod. I will try to get a close up pic this weekend.

Don't worry too much about it, they are almost identical and they take the same parts(Smile ;-D)
