There is alot of great information on this web site but I would like to get some feedback on my specific situation. I am a homeowner with 11 acres and am close to purchasing a Z mower. I currently use a woods 6ft. finish mower rear mount on 30hp tractor (average cutting speed 5mph) I want to reduce my mowing time. After doing alot of reading on this site, I believe I will purchase a Hustler Z. My questions are these. With a 72" deck which engine would you select. 27hp kohler 28hp kohler EFI 27hp kaw L/C And would you pay the extra for the Super Z Right now I have a price of $7199 +tax for a Hustler Z with kohler 27hp the new suspension seat and 72" deck (2005 model new) A Super Z with Kaw 27hp L/C suspension seat and 72" deck is $8,200 Also, what is the average mowing speed? I'm guessing 8mph on fairly level terrain. Thanks for your responese.
