Need Operator's Manual for Murray Select Riding Mower (MS18542)

I've been searching online for an Operator's manual, been to the Murray sites (they only have a parts list), Murray Owners World (MOW-only have 1967-2005), Husqvarna Outdoor Products/ HOP (only have parts list) and Briggs & Stratton (got engine & parts manual).

The information I have so far:

Model MS 18542

Murray select Automatic Drive 42" cut

18.5 HP Briggs and Stratton engine 33r777 0003 G1

I think it's 2013

I have NO experience with a riding mower so I desperately need the instructions on how to operate and for maintenance. Any suggestions for where to find an Operator's manual.
