I have Houston Black Clay and clump grasses like Fescue and Dallis grass. In the late summer the cracks and clumps make it one rough ride. I have a disc harrow that is heavily weighted so that it will cut into the hard clay. In late August I went over the place with the disc a couple of times digging up some loose material. Came back with a chain/spiked harrow and smoothed it out. After the Sept. rains came I had pretty smooth grounds; fields and surrounding areas.
On Bahia and Bermuda, toss in some Johnsongrass too for grins.......just try to kill it. They will love you for trying.
On sandy loam, I don't know why what I do won't smooth things out for you.
My harrow came from Small Farm Innovations in Caldwell, Tx. It has pipes at both ends which can be removed if desired. If I want to move soil around, I leave the rear pipe attached. The spikes loosen and smooth making a crest/pile of matter riding up in front of the rear pipe which disperses as low spots are traversed.
Years ago I had a JD batwing, fixed tooth, rigid frame, spike harrow that definitely would really move dirt around and fill in the low spots. I didn't like to use it on cultivated land as it would make big piles of matter riding up against the frame...preferred the chain type without the rear pipe that floated across the ground for the best smoothing.
