Looking for advice and opinions on the John Deere 997 Ztrack mower with 72" deck and the Kubota ZD331 with 72" deck. I'm mowing approximately 6 acres of lawn about twice a week. 5 acres are relatively flat and one acre is on hill side. I'm looking to spend less time mowing -- even considered contracting out the mowing. I stopped by local dealers to get info and prices --- was quoted a price of $14,500 for a new 997 ZTrack and $14,600 for a new Kubota ZD 331. Or, should I be looking at other Z turn mowers? Any advice/opinions are greatly appreciated. Thanks.
