This is something I find extremely odd and was wondering if anyone may have a reasonable explanation? What would your reasoning be that an electronic fuel injected Kohler engine with only one more hp (27 to 28) could cause the price of a Hustler Super Z (example) to be $1000.00 more? Then you take a Bad Boy AOS model mower and go from a Cat 28 hp 3 cylinder diesel to a Cat 35 hp 4 cylinder for a price difference of $900.00. With the Cat you are getting 7 more hp and another cylinder which means more metal and parts involved. The 28 efi is nothing but a Kohler 27 hp engine with fuel injection. What is your reasoning on this crazy comparison?
