So back in the day they were all battery powered machines as most breeds will chase the lure for a couple laps and be done so the machine gets to rest and cool off. For huskies because of their endurance they can pretty much go all day when they’re in shape, chasing the lure so the machine couldn’t keep up with them because of the battery power. So after a lot of research and working with my team, which includes a master electrician, we came up with the idea to actually use a winch that’s electric powered (plug in) as it won’t be subject to getting as hot as the battery machines. I actually had a battery machine catch on fire, which was really crazy but not near the dogs. We had the machines isolated at that point for safety reasons, but the battery machine was drawing too much from the batteries and constantly running so they overheated! So my design worked for many years and it was super reliable. It just didn’t go quite as fast as real lure coursing machines will go over 40 mph as they’re designed for Sight Hounds and they can go 40 mph plus, my machine was probably 25 mph and huskies can run 30 mph or so. So today the brand I’m using here which is lucky dog makes an electric machine which is professionally built electric (plug in) to run for a long time without overheating like my machines worked. There’s also a company called Swiftpaws.com I think they offer an electric one also but they also have a home version smaller which has little batteries, my machines used car batteries but now I also use one of those little battery machines for my little dog, which is perfect, so depending on the dog, you’re running it might be all you need at least to start out…
