Not me, but I do envy you. Those are some bad boys!
You have an impressive list including the M8540. I looked at the M9540, but will some times handle round bales a little bigger than it is rated, so looking at moving up.
I will be needing a tiller to prep for shelterbelts and am looking at the SR-240 94" tiller from CCM.
I have a126x with a loader,with 150 hrs. I have been pleased so far.
