I certainly have no experience other than observing. But, are you speaking of only of greens construction, grading out the sub-grade, shaping the surrounds, then filling and spreading rootzone mix, and floating the contours prep'ed for seed, all with one machine?
I heard Sand Hills was done with a smallish backhoe, box blade, smithco, and hand work... of course, look at the ease of working in sand.
Doesn't much of this depend on soil characteristics of subgrade, and greens construction method and size? Isn't spreading the RZ mix to large greens with USGA method construction more problematic with the heavier D6 or 5, and the lighter you go down to D4s, or the smithco, it becomes the method of choice, with hand floating at the finish before seeding? Push up sand based greens VS USGA method seems to offer ability to use different machines, doesn't it?
