Pull type disc harrow

[charlton289]

I borrowed a pull behind disc harrow I was wondering if anyone can identify it. I pulled it with my GC 1705 no problem until I got in some really soft stuff but I had it in 4 X4 pulled it just to right thru. It has some green paint on it but it seems to be from the 60's

I think more like the 50's. If memory serves that depth ratchet on the tongue looks like John Deere but it's been long time since we had one.
