I have a 30-in DR brush machine with 500cc Kawasaki engine that I bought 15 or 20 years ago. The thing is a beast. I've had no problems with it. When I needed small parts I was able to get them within a reasonable amount of time. The reviews have read since generac bought the company are not good. I was considering buying one of their electric lawn mowers but I'm going to have to think hard now
