In another thread I posted I'm looking at a Exmark Quest with Briggs 22HP ELS engine. Doing searches I've read that some people say to avoid this engine and others say it's fine. Are there widespread issues with this engine and if so, what are they? Are the people that don't like it ones that use it commercially putting a lot of hours on it? I would use it to mow my 1-2 acres and that's it. I did test drive the Quest today on pavement and really like how it handles. It has the ZT2800 drive system. I drove my buddies 2004 Hustler Fastrak yesterday and it didn't handle as smoothly. I don't think his has the ZT2800 drive but the new Fastraks do now. I'm sure either the Exmark Quest or Hustler Fastrak would give me many years of service. I'm just wonder how the Briggs ELS engine would be for residential use?
