Here are a few pictures of the Elec-Trak. You can see the damage done by battery acid. I will be looking for replacement panels. Right now I am using three 12 volt deep cycle marine batteries in it instead of six 6 volt batteries. I don't think the run time will be as long with the 12 volt batteries.
The Model # is 26AE14AA and the Serial # is LSI5 529. Hopefully I can find what year it was made. my plan for this is a three point hitch and a plow.
