Anyone seen this attachment? What is it?

We used a similar unit that was towed by a tractor at higher speed. It was called a Rotary Hoe.
8' wide I think.

Roundup ready corn seed put most rolling cultivators in the bushes down in these parts, I sold a 4 row set that I had but kept my 2 row set for gardening, as someone else said once you have them adjusted properly let the hide go with the hair and don't look back till you get to the other end.

Hey all, hoping someone on here will have seen this before and know how/what it's used for. I found this around the barn. My FIL used to have a super A, 140 and years ago a JD 4010 I think it was.

I am hoping it is used to clear weeds out of the rows.

Also if someone has used this before do you mount it with the spurs pointing out? How deep does it run? Surface or all the way down?

It has a 1" shank so I could mount them on my cultivator mount.

Looks like a segment from a Lilliston rolling cultivator, used for cultivation and weed removal of row crops in California. There are righthand and lefthand units, can't see this good enough to tell which.
