You asked if we had any ideas then mock the idea that is most often suggested. You're obliviously not serious about selling this thing.I haven't read through all the posts here, but there is a Kubota dealer near me that had about 15-20 6' bush hogs. It has taken over two years and he just started to sell some the past couple of months. He must have dropped the price.
I suspected you were in denial that's why I said the hard truth. Good luck.
