Where can I get an Owners Manual for a Craftsman Riding Lawn Mower model 917.255916?

Recently purchased a Craftsman Riding Lawn Mower with a Briggs and Stratton engine in nice condition but without an Owner's Manual. Would like to know about maintenence such as grease points, type of oil and grade of gasoline to use, etc. Sears and other parts suppliers say owner's manual is no longer available. Does anyone have a manual that they can copy and send me, or FAX, or scan and email, or just send so I can copy and return. Will pay for manual or efforts. Thanks.
