Need a manual for poulan pro 42" riding mower. I tried to open one on line and half the page is gone. Help please. Disabled widow trying to do what I can on my own to keep my mower running. I know it needs oil change, filters etc I don't know where everything is located or how to take those things undone without pictures and direction.
