For maintenance on my rock driveway, nothing seems to work as well as my old road drag, however it is not very maneuverable. So, using an old cultivator toolbar, I am working to make it work off the 3 point on the tractor, using just chain links. It works, sort of. Until I get the drawbar pull chain adjusted better, it jumps and nosedives. When I lift it very far up, it swings into the tractor tires. Anyone done this before? Any words of advice?

I built this drag for smoothing pulling tracks. It would need weight to cut a hard packed driveway but it would smooth it well. The cutting blades are state highway snowplow cutting edge.

I like that. Good job!

Use a boom pole on the 3 point to do the lifting. That way you can make the drag chains longer and less likely for the front to dig in.

Jaden, my drag works with little operator effort. Once the top link is properly adjusted the operator simply drops it and the front and back have equal weight and it pulls smoothly. You need to just lengthen that top link chain because the front is catching a lot more draft than the back. More length will even the weight so that the front will no longer dig in.

That looks like a good outfit

If the tool bar is dedicated to the maintainer, hinge the front cross member to the bar with clamps, and trim off the curved attachment points ahead of those. Put a solid bar link to the former lever rack instead of chain. Put a chain or telescoping top link on it instead of the solid link.
These should limit the sway to the 3pt limits, and allow float with the 3pt. If the front is too heavy I would attahc a spring loaded pair of wheels just behind the front blade to limit diving in, as well as providing some tracking. Jim

We had a 3pt drag when I was growing up that we used on our 8n tractor. It was made with a boom pole to lift and pull, and we used it a lot. The boom pole had a pull bar the width of the drag-8ft as I recall. The drag was made out two 4ft sections of angle iron, vee side down,about 6 lengths of angle iron,as I recall. It flexed in the middle because the 2 sections were side by side.Four 1ft chains attached it to the pull bar, and the boom pole lift had a vee frame the went down to each section. The vee frame(just like the front vee frame-only bigger- that the 3pt supported the boom pole with) attached to the boom pole just past center. It worked great-it would smooth a field,or a yard(we finished hundreds of yards over the years-new homes or remodel jobs).(Our farm was surrounded by growing 50s and 60s suburbia.) It worked great for knocking cow pies apart,too. We also used to drag ball fields with it-smoothing the infield.
I guess ,if you can picture my description, maybe you could incorporate a boom pole lift beam into your design and do away with too much chain. Mark.

I made a 3 point V-shaped leveling device.
It does a great job, but you will need lose gravel if you want to repair a road.

I used to level the dirt when building the pole barn.

If you drag this across lawn, it will remove the high spots and fill in the low

spots.
