I am looking to buy a zero radius lawnmower.  My wife has come across a used Hustler Raptor 48" with 60 hours on it.  It has a 19 hp S31Q677  Briggs and Stratton Engine.  I am curious about the engine.  I do not see anything to indicate that Hustler ever put Briggs and Stratton engines on their mowers and the 48" all seem to have 22-23 HP motors.  Should I be concerned about the engine and mower?
