Ok, I'm seroiusly considering the Husqvarna CZ4815 with a Kaw engine or the CZ4817 with a Kohler engine. Both come with baggers, look like the same machine. The 15HP Kaw is $300 more. price is on New (dealer got them late fall 2003), 2 yr warranty starts day of purchase. $3800 for Kaw, $3500 for Kohler. Kaw is a twin cyl., would that be quieter? Am i losing any tip speed with 2 HP less? Please help, i would like to get a ZTR without paying $6500 for one. Keegan Please comment if you have either of these machines.
