Getting frustrated with this one, I was given a Toro sit down by a guy going out of buisness, he said I could have it because it was a "piece of crap." Turns out, it just needed maintenance (spark plugs, oil change, filters changed, grease, new blades). Mower was working great for a few weeks, then the battery died on a hot day (95 degrees). Replaced it with a new one, that one was fine until we had another hot day. Took it to a mechanic, he said he couldn't find anything wrong with the electrical system. Bought a new battery, was working great until today when we had another ninety something degree day, battery died again. I want to try and see if anyone has any suggestions, I have no knowledge about electrical systems, and my mechanic is no help.
