CNC , your bush hogging now to promote summer vegetation ? Rather than leave it all standing until fall planting or is there seed and fertilizer beneath the mowed section. I'm guessing it's easier on the transmission to cut periodically throughout the summer so the bio mass mat isn't to thick ?
If I didn't need to spread some lime then I wouldn't do anything to it. My pH still sucks though and I've decided to just make that my top priority this summer. Figured I'd put down the hay and then call in the spreader truck. It's actually mowing really easy. In the future I'll probably mow the rye early while its still green when it first starts to set seed to thin it out some and then let it go from there. When I get my pH where I want it, I hope to have a better component of yuchi and durana clover.
