I've done both - and I'd suggest you mow it earlier or higher to stop the cut forage from smothering the plot.

You can bail it - and sell- but when you do - you take away - all the N-P-K that you put down, plus decent anounts of Calcium and other trace elements. Why not clut it more often - and let the residue "go back" into the plot?

My 2 cents - If your soils is Xtra fertile - then sell it off - why not?

But - If you work hard to get it up to par - then protect your investment - and cut it - or turn it under every year or two.
