I've run scag and exmark mowers for years. I just purchased a Great Dane Super Surfer 52inch 22h.p. kohler on it. This seems like a great concept for mowing small to medium size acccounts which would normally object to a rider on them. I was just wondering is there a fatigue level after a certain time of standing all day and if this would be a good mower for acres? Thanks for your help guys!
