Well, after 28 years with my Kubota T-series lawn tractor, I have finally decided to upgrade to a new mower and I'm on here seeking advice. I've never used a zero turn, but I think that's what I want to go with this time. I have just under an acre of flat ground with few obstacles. My dealer carries SCAG and Gravely. I think I'm debating between the Liberty Z and the Gravely HD. I like the fact that the SCAG is not as heavy and from what I've read the maintenance is easier compared to that of the Gravely. The SCAG is also about $500 cheaper. The Gravely has the 3100 hydros (2800 on SCAG) but I'm guessing for my yard that won't matter much, and I'm not plowing or pulling equipment with it. Lastly, I've noticed that bagging systems with z-turns are quite expensive compared to the lawn tractors. I would use a bagger quite often with my Kubota, but I'm thinking with the higher blade tip speeds of the zero turns that my cut will look better, even without bagging. I realize that I'm on a SCAG forum so I'm assuming most replies would favor the Liberty Z, but I'm just looking for some honest opinions and advice....thanks!
