Well I've asked questions before while searching for one of these units. Now I have hauled home a non-running 620. Any info you can provide me would be much appreciated. I would like to find a pdf file of the operators/owners manual. I could also use a wiring schematic/diagram. The engine is not tight but it does not run. I believe it is electrical.

Thank you for any information.

I can help with specific questions. Too many details to cover everything. You can go to Simpletractors.com for lots of info.

I can provide copy's if needed, pay print/ship charges, no PDF.

For help with the Onan engine, there is an Onan engine discussion group on Yahoo Groups. Most of the guys there are Case garden tractor collectors, but other than minor details, the engines are the same.

Her is what you need.

Go to this site:
http://www.simpletractors.com/

Use the conversion section to convert your model number to the equivalent Simplicity model.

Then go to the Simplicity site, link provided there, enter your model number, and print out the needed manuals.

I just downloaded and printed, and burned a CD, of all the manuals for my 616. Sure is a helpful site for the small ones.

Thanks guys. I have been to Simple Tractors but kept getting an error message when trying to look up the manuals. It worked this time. The wiring diagrams/schematics are what I need to get started on getting this thing started.
