Hi BDA, we have both the parts list and operators/owners manuals in the Parts List and Manuals area which is located in the main forum topic "Lawn Mower Frames". This is accessed by subscription, instructions for which is in the second topic in any thread on the main forum page.
The ones you need to download are the Scott Bonnar Spare Parts List for 14" 17" & 20" and the Rover/Scott Bonnar Operators Manual for Models 45048 & 45148. Don't worry about the model numbers, it will cover your model as well as most parts are common for all Model 45 Scotties.
