I have 3 acres which was once a tobacco field, so the grass is more weeds than grass. There is a lot of clover which is very thick and holds the dampness. We purchased 2 - 17hp, 42" deck Yard-Man just over a year ago and have already put over 110 hours on each, they struggle through the thick clover. Our original thought was that having 2 people cut at once would knock out the work, WRONG. We are now looking at purchasing a commercial zero turn radius mower. We are considering a Kubota ZD21, we especially like how the deck rotates for ease of cleaning. But I'm not sure if the 60" deck is going to reduce our cutting hours that much. Also, the $9K price tag is fairly steep but appears to be in line with the equivalent Toro's and JD's that we have looked at. Suggestions?
