Preparing bids on 2 apt. complexes for 2004. Each is app. 7 acres and some trees nothing to the extreme, and a Walmart and Home depot, 4 acres each, and will be cut each week. Currently have 1 60" ztr. and need to add another mower for these properties. It will be a 72" something. Would you guys go with a ZTR or step up to a 300 series Toro or Hustler 3400 with a diesel?
