Depends on the size of the lawn mostly. A push mower (or better yet a powered drive push mower) would have the best control in rough terrain, but if it is a large lawn a riding mower is better.
Two of the best mowers for rough cut mowing are DR Field and Brush Mower 44" 10.5 HP Premier - Tow-Behind and a Swisher RC14544BS Tow Behind Rough Cut Trailcutter Rough Cut Tow.
It depends how quick you want to get it done. You would need a specialist fairway mower, rough mower and green mower.
