I have looked all over the internet and not figured out what brand of grader that I have. No data plate that I could find and no stampings or part numbers that I can see.. The tires are   10,00 by 20, to give you an idea of the size. It doesnt look "shop built". It is well done and strong.  Any idea of what brand it might be?????  Any help will be appreciated.                                                                                                                                                                                                                                                         Grant.   

cat drawn type graders were similar to that. the front wheels look to be missing.

That rear axle is a Ford two ton truck rear axle, I have the same axle with duals under my blade trailer.

I wondered if it had originally been steel wheeled. I am pretty sure it is not a Caterpillar product. I have looked at dozens of pictures and not seen that sort of rack and pinion blade control.. Maybe somebody will recognize it. Grant.

Are there any books that cover early graders. I seem to remember a photo book of graders, but I dont recall where I saw it. Grant.

I have looked at many pull graders in my travels. Most have a worm gear lift. Never seen one like that.

The rack looks very much like what is on a John Deere 36b combine which was the Holt design. So maybe that would indicate the grader is related. But just another guess.

I looked at several videos about the John Deere 36b and didnt recognize anything similar. Maybe I missed something? Grant.

Maybe an unfinished Rube Goldberg contraption??       That's my story and I am sticking to it!! 

Grant, that doesn't look like anything I have seen and it looks pretty good for a shop job.  The racks look way too long as one could lower the blade way past the stabilizer. 
Kind of a mickey mouse way to attach the large leveling wheels as it uses "U" bolts to attach them to a smaller disc for the adjustment.

OK! we give up!  What izz it?? 
 

This may be like the OT Scraper that is on the other thread. Built by one of the many small shops that never got famous enough to be remembered. I would have thought that even a small shop would have put a data plate or welded a name someplace. It may remain a mystery??? Grant.
