I'm looking at getting the 20HP/52" Fastrack and I have a couple of questions. The dealer I talked to said he has a 20HP Honda and a 20HP Kohler with the 52" deck, and the Honda is $500 more. Does the Fastrack actually come with a Kohler and if it does is the Honda $500 better than the Kohler? The 4 year warranty on the Fastrack is a full "bumper-to-bumper" warranty for 4 years? The dealers I talked to knew nothing about the 4 year warranty and stated that it only had a 2 year. I called the 800 number on the Hustler web site and the guy I talked to there said something about the engine having a 2 year warranty and that some other parts only had 3 year coverage for the labor. Could someone please clear this up for me? Thanks.
