I've been mowing my lawn for the last two years with a 42" Cub cadet lawn tractor. I mow around 3 acres of mostly open, level to rolling land with the Cub, and I bush-hog an additional 5 acres with my tractor. The yard takes me around 3 1/2 hours each week, and it takes me around 4 to 5 hours once a month to bush-hog. The land that I bushhog is very clean, and would look beautiful mowed like a lawn. So I'm considering a ZTR to do all 8 acres with. I've checked on a new Hustler Super Z with the 27 hp Kohler, and 60" deck. I was quoted a cash price of $7900 plus tax. A man that I work with has decided to get out of the lawn business so He has offered to sell me his 2004 Kubota ZD-28 with 72" pro deck for $8000. I know he takes care of his equipment so I feel like it would be a safe deal. It has around 330 hours on it with some warranty left. After Taxes the Super Z would be around $700 higher than the Kubota. Would the used Kubota be the best deal or would the new Hustler with the full warranty be the way to go? You guys know your mowers so I look forward to any insight that you may have.
