Hello, need help finding out where I can find model number on a 2005-2006 Lazer Hp. My freinds mower,he blew the 23 hp Kolher now he wants to replace the motor. I found a ps number and serial number on the motor but no model number. Is there a place on the mower to find the serial number? This mower is well used and I need the exact location to start looking for numbers. He has lost all paper work so any help would be appreciated.
