these are a cultivator that I found buried on my property when I bought it I converted it to either used on my fel or 3 pt. It works pretty good. When used on fel I can put down pressure to loosen my road bed so I can land plane it. And on the 3 pt. I can use it to loosen my garden bed and the other day I had to move some brush and it made a good carrier had to hand load and unload but it saved a bunch of trips to the brush pile.I have a "factory built" cultivator;nice tool.I added "peanut shares" from AgriSupply to mine.Lots of torque involved;so more bracing needed.I would tie the frame together at the front ?
