Why does the GT 1554 have a 27hp Kohler Command engine? This was brought up on "the other" site and I didnt want to hijack the thread. Is it just for customer eye candy, ohhh it has a 27hp vs another brands 22 etc. It just seems odd that the 1500 series would have a larger HP rating than the 3000 series. Especially when the 3000 series weighs an additional 500+ pounds when including mower deck.
