Look up "Elec-Trak E15." Built by GE in Rochester(?), NY in the early 70s. It was part of a broad line from E8 to E20, where the number refers to the horsepower of a roughly-equivalently-perfoming ICE tractor. The E15 is the largest frame. They had a lot of available attachments including mower decks (front- and mid-mount), snow blade, snow blower, tiller, front-end loader, weight boxes, extra battery boxes. There were also a lot of hand tools that would plug into a special power outlet, including a hand drill, chain saw, welder, AC inverter, weed whacker and probably a few I've forgotten. GE sold the line to Workhorse, who sold it to Avco under the New Idea label. Mine is an Avco EGT-150, essentially identical to the E15. I sent you looking for the GE E15 because there's more info on it, but there were very few changes throughout. Mine has a mid-mount deck and a snow blade, and I modified a Black & Decker weed whacker to plug directly into the power outlet. These were made with all the sophisticated technology you would expect in the Apollo era. (Not a single solid state component, all contactors, relays, micro-switches, big cables and batteries.) Failures happen, but anyone with basic hand tools and a volt meter can fix it. You can still get parts. So 40 years later, it tenaciously refuses to die. Fun fact: Apparently at some tractor pulls they run a class for garden tractors. You'd think that would be just for a laugh after everyone in the crowd has already killed a six-pack, but I'm told that some of these guys get Very Serious about their highly-modified garden tractors. But few have heard about the Elec-Track (even less about the later Workhorse and Avco versions). I've heard that a few ET owners have walked off with first place driving bone-stock ETs. Not surprising when you consider they have a total weight of 800-900 lbs, 400ish of which is in lead-acid batteries, most of which are directly over the rear wheels, and they of course have low end torque no ICE tractor can even dream of. Some people keep theirs pristine and collect all the attachments and tools. Mine's a tool for getting things done, with all the scrapes, dents, repairs, patches and built-up crud you'd expect on a 40-year old tool. Chances are very good it will still be running long after I'm dead. To bring all this back on-topic, electric power makes it much easier to build vehicles that last virtually forever. There is simply no reason for your transportation to need replacing as often as it does, except to keep putting your money in someone else's pocket. We keep doing that because companies don't want to give us that option, for the sole reason that it limits their profits. That's a big spit in the face to anyone who believes capitalism gives us better choices. Big truck tractors have lives in the millions of miles, because buyers demand it, because cost per mile is everything to them. Consumers are more easily fooled, so they are. EVs can help turn that around. I'm going to attempt to make my EV the last one of its kind in use. Because the only reason it shouldn't last forever is that people falsely believe that's the way things must be.
