For sale John Deere Z820A 60-in cut, gas engine and I believe it's a 25 horsepower Kawasaki with 840 hours on the engine. Everything works on it as it should with the exception of loss of power on the engine last season. It starts up it doesn't smoke but for some reason it lacks the power that it once had. These engines should get 2,000 hours or so. Honestly, I don't have the time to put in to troubleshoot and I've already bought a replacement John deere. This may be a great deal for someone it may be something simple or at the worst case an engine which runs about $2,500 bucks.
