I hope to eventually achieve 'decent ground' on the ~2.5 acres i have to mow. I have tried a couple of zero turns I was working on for others out here and the ride is too rough to use the greater speed. But, i intend to eventually rip up and smooth out the whole thing and start over as there isn't a spot of grass on it i actually like anyway (used to be a hay field).
Have you tried a suspension machine?
