We have had this section of a Deere spike tooth harrow for many years. My grandpa did have another section of it but either sold or scrapped it, he can't remember. Originally we hooked a chain to it and dragged it with our ATV. Once I got a sleeve hitch for my 214 I built a pretty crappy sleeve hitch mount for it. It worked well and I mostly used it for dragging the gravel driveway to the shed. Since selling the sleeve hitch and getting the 3 point hitch on the 317 I wanted to make it 3 point compatible. After some research I found what the original mount system was and scaled it down for use with one section and Cat 0.
Here is the drag section we have. (Not ours exactly, but a photo from Google).
Here is the mount system I found from a Deere publication.
Its a pretty simple design, and uses chains at four points per section so that the harrow can float. Scaling this down here is the design I have to build my own.
The A-frame is connected by U-bolts because of the way the drag is offset, it won't be exactly in the middle and I may need to adjust it to be balanced. I also made the arms offset more than they may have been originally so that I can chain the rear of the drag up higher when getting on/off the trailer. I shouldn't need to trailer this often, but a few potential job opportunities might be dragging baseball fields and driveways. I need to get this put together fairly soon since the snow is melted and it is time to drag our shed driveway.
