It is rough in spots to be sure and is not what I'd call comfortable, everywhere. But I can get it done in two hours. The bouncing is more from the vole structures (some reference them as moles) than leftover horse hoof pits. It can get so bad on the bouncing I will have to come to a complete stop. But, full speed can be more smooth than a slower pace, depends on the area.I am curious about your mowing of the ex-horse pasture. The OP mentioned hoof pits. Is your pasture smooth enough to mow comfortably? It sounds crazy, but would it be any advantage to have the pasture rolled to smooth it out? I'm a village kid so be easy on me.
So, I would like to have it rolled for that, but it would take a very heavy roller on moist soil and I am not sure how long it would last with the vole mounds and tracks.
