Hello, I have just moved and now have 1 acre to mow. The 21" Honda mower I have is just not going to cut it anymore. I am thinking of a ZTR in an attempt to speed up my weekly lawn mowing. I have been looking around for a used/demo unit but have not found much in my area (Hopkinton, Massachusetts). A dealer close to me has a demo (last years model, only 3 hours on it) Gravely 34Z for sale for $3950. I know a commercial machine is a little bit of overkill for only 1 acre per week, but the residentail zero turns just look so cheap and the ground speeds seem slow. I would rather spend some extra $ and have a machine that will last. My dad has a Gravely walk behind that he has had for 20+ years and it is still going strong. Any thoughts on the price of $3950 for a demo 34Z with 3 hours on it? Is this a good machine? Thanks, Steve.
