these are two pictures of the road drag that I made.

It is based on the split log drag invented by Mr. King back when most
roads were dirt.

You can't quite see it, but there is a piece of .187 x 1.75 steel bar
welded to the front edge. You can see the dirt scraped up by this bar
on the right of the first picture. The bar is welded on so that it
hangs about .500" below the bottom of the 5" channel iron.

The dirt that is scraped up flows to the center of the road and is
smeared flat by the rest of the 5" channel, and the second 5" channel
that follows.

Interesting. I'm guessing that the angle and weight help to keep it
straight behind the single tow line?

It will 'skate' to the side depending on the soil type. But that is
self limiting as the angle changes as it skates out. A shorter tow
line will make it self limit sooner.

In addition a shorter tow line will make the drag less aggressive.
That is because as the tow point is above the ground (20in?)the front
of the drag is lifted up as the load is increased.

The angle is also adjustable via the chain and grab link. More angle
(up to 45deg) moves dirt to the center of the road, less angle is
better for filling in 'potholes'.

The best action is after rain when the top of the road surface is
damp.

I guess they needed grading tools way back then, huh?
