I am looking to purchase a new mower soon (within a week). My current mower is a JD 757 w/ a 25 hp Kawasaki. I really like the mower, but last season at about 400 hrs. the engine started leaking oil. The dealer finally replaced the engine after working on it all summer. The mowers I am looking at are the XT3200-60 and the SP2800-60 and the XWF2700-60. I really like the Kohler engines and I am really interested in the Supreme series, but I am a little worried about the EFI system. I already have some prices and the XT3200-60 and SP2800-60 are the same price basically. Any comments or suggestions will be greatly appreciated.
