John Deere Spike Tooth Harrow

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.

Got the materials and got it put together this weekend. Everything went very well except for where the chains hook to the drag. Some of the chain hooks were twisted and I couldn't get the chain in so I ended up just welding them straight to the drag. I am happy with how it turned out and it should work well. Of course the moment I finished it the rain started. To use this design for any other width of drag it would be very easy to just shorten or lengthen the main beam. Total cost in steel and materials was $71 and it took me about 2 hours to get it all put together.



The main beam is way overkill for this being .25" wall, but my steel supplier was out of .188" and I didn't want to go down to .120" wall.

Enjoy,
Ryan
