Thanks for the compliment.
My experience in harrowing Bahia pasture grass, which has roots 6"-8" deep, has been that it takes multiple passes, at ten day intervals, to get ahead of it. (I am trying to eliminate the Bahia in a two acre "safe zone" surrounding the community burn pile.) In the process, I have chopped Florida sandy-loam finer and finer as the early cut Bahia decays but new growth occurs, in decreasing stands. At first the disc only penetrated 2"-3" into the tough Bahia root zone. Now the discs are going down 7" in 90% clear soil and I have to set the throttle at 2,000 rpm in HST/MED/4-WD to keep moving at a brisk pace and not stall.
I would not describe harrow action as lifting the Bahia. The discs cut, chop and throw the grass. The "throw" is two parts, first out, then in. Perhaps a fine distinction. When working the Bahia, harrow is adjusted "half-way" in terms of adjustment holes available.
A 14" turning plow, which I have, would have cut, lifted and turned the grass 7" deep but the harrow was new and I wanted to let it teach me.
For 'Stage 2' vegetation control at the burn pile I will use my Landscape Rake.
Bahia should be much less next year as there will be no seed this year.
An irony: By September most years standing Bahia would be golden, dry and flammable. Atypically, we have had frequent rain this summer so the Bahia is still green and lusty, which is why I have had to harrow it repeatedly.
Nature's way.
