Looked at a 72" Super Z with the Kohler Command Pro 33 hp EFI 824 engine to replace the 60" Hustler Z with 25 hp Kawasaki carburated engine I recently sold. I have been running Kawasaki engines on mowers and UTV's for a long time and have zero experience with the Kohler. The dealer said Kohler has been out for about 3 years and had been giving good trouble free service. My engine preference, I think, would be the Vanguard EFI, but I would have to go up to the Super Z HD to get that. I live on a 107 acre farm and have a four acre lawn area that is mowed about six times a month during the growing season and a 20 acre hay meadow that is mowed twice a year for weeds, not hay production. Any comments or feedback before I make a decision to buy would be much appreciated. Vic
