Does anyone have any idea what kind of dozer blade this is?
I was wrong... but it does look like a tow behind/ pull type grader frame like the AG guys use
I can only see one of the images you posted, but looks like it could be a slope board
What kind of dozer would this of came off of?
Looks like a slow board maybe off of an 8 or 7 if I had to guess
It looks like a grader blade welded to a frame. Does it have a grader cutting edge
I agree. That looks like a grader moldboard with an approximation of a PAT setup welded to the back side of it. As regards to what type of dozer it could have come from, no idea. It's a home-brewed setup by the looks of it, it could have come off anything.
By chance could it be a slope board for a grader
I thought it looked a little like the "no circle" arrangement on a Puckett or a Basic 601. Couldn't find a supporting image and no slide supports the slope board hypothesis.
It looks like a home made snow blade. It seems to pivot freely in the center, unless there is a piston on the side you can't see.
