I'm looking at the Exmark 32" w/b (M3213KA) and the Gravely 32" Pro G (GR1332), primarily for residential lawns. I understand this is the first year for the Gravely 32". I like the bigger tires on this machine as well as the spring loaded pins to adjust the deck height. Both mowers have the Kawasaki 13 hp engine, same transmission. The Exmark weighs 420 lbs and the Gravely weighs 500 lbs. Am interested in your comments and wanting to know if anyone has had any problems with either machine. Anyone ever use this size w/b with a stand-up sulky?
