I made a drag that works great. It smooths the roads and also smooths our food plots after plowing and discing. Sorry I don't have pictures. I used 3 seven foot pieces of 4x6" angle iron which are pretty stout. I drilled three holes in each, one in the middle and one near each end and placed hardened eyes bolts. Then I connected each angle in parallel about 3 or 4 feet apart with 3/16 chain. I then criss crossed or wove chain between the connecting chains to make sort of a net, and connect these crossing chains to each other with links. Added a length of chain on the front attached to the two eye bolts to make a pull harness that I connect to my drawbar or even the bumper hitch on my car. This thing weighs about 300 lbs. and is indestructable. I have pulled it many miles around our roads and food plots for ten years. You can find scrap angle at any salvage yard pretty cheap and the only other cost is the chain and connecting links. It is unbelievable how well it works. Our food plots had 18 " deep ruts from the plow and disc, and after several passes, they look like a lawn. You can also drive pretty fast, as it works better at speed. Since we have no cultipacker, we use it to cover our seed, also driving very fast so it won't cover them too deeply. When going slowly, It moves dirt so well, that it will occasionally stall my 70 hp Kubota. It moves more dirt when the angle irons are turned down. We find it more comfortable to pull it with a vehicle as you can do it in comfort with air conditioning and smoother suspension than a tractor. It also allows one person to be on the tractor discing or seeding and another to follow in a truck pulling this drag. Makes finishing food plots quicker, and it takes no skill to drag this thing around.
That being said, I would hesitate to pull it with my 4 wheeler. If you snag a rock or hang it on a tree going around a corner which occasionally happens, I fear you could bend the tubular frame of the 4 wheeler. If I need to drag tight places that my vehicle or tractor could not reach, I would buy one of the common drag harrows made for a 4 wheeler or make a smaller lighter version of this. But I agree that a four wheeler is an expensive toy to use for dragging, and I will pull drags with my truck or tractor when ever possible, as they are simply much less likely to be damaged. Dragging with a 4 wheeler can't do the transmission or frame any good, although I am sure lots of people use them for this.
The only problem we have with this is turning around at the end of a narrow food plot. We try to design our plots to avoid narrow dead ends. Worse case, you can disconnect it, turn around, drive over it and reconnect it and the pull it back over itself in tight spots.
I hook it to my truck when I drive around the property and smooth the roads frequently. You don't even know it's back there. Just take the turns wide as if you were pulling a trailer.
By the way, I prefer to not attach the chain directly to my trailer ball, but instead use a short six foot nylon strap (like a tree strap used in winching). This acts like a shock absorber to give a little when the drag snags something, to reduce the shock effect on your vehicle.
