Where can I find manual for 1995 Lowes Riding Lawn Mower?

I have found the deck parts list, and the engin manual, but i cannot find the parts/diagram for the PTO clutch/system, the drive belts etc. Any ideas? The model # is 145S848h062. I push the PTO lever up and the blades do not engage. Not sure how to fix it because i cannot see what all is involved.
