I'm going to go and look at this cletrac over the weekend and was curious if any of you recognize the blade on this 1941 HG-68 model?  From speaking with the owner it has a 3 hydraulic cylinders, 2 for left/right, and one for upward and downward motion.  To me it looks home made, until he told me that the upward/downward cylinder is used by a toe/heel foot pedal.  That would require quite of bit of work via home ingenuity.

I know the anderson blade has 2 cylinders for up/down and 1 for tilt up or down

I know the picture is bad, it is the only one I have via the ad for the tractor.  I'll be getting a few more over the weekend.  In any regards if anyone has any thoughts figuring out if this is OE blade or something that was put together with parts and pieces.
