Last summer I worked part time for a John Deere dealer and learned one thing, not to buy a DEMO mower. You can try a Demo mower but don't buy that one, get one out of a crate and watch them put it together. This dealer had almost 5 acres of grass, and they had this M655 with a 54" deck, and the hourmeter showed like less than 14 hours or so. But all that summer they had me mow it with the meter disconnected and I put several hours a week on it, powerwashing and cleaning it each time. This one nice guy came in and tried it and bought the very mower and I felt sorry for him cause I knew he was getting a mower that had probably almost 90 hours on it and he thought it just had a few. THAT IS CHEATING THE CUSTOMER! Of course it had a little cheaper price and a full warranty, but still even under warranty they might have more breakdowns than normal and that is just wrong of a dealer to do I mean it is a pain up the @$$ to have to mess with this mower because it's breaking down sooner than it should and it gives the dealer and brand and brand of engine a bad name. Not advisable for anyone to get a demo model. Try it, and if you like it then get a new one out of the crate. You never know when this will happen. I know most of you are aware of this, but I just want to remind you since most are getting new machines this year. Watch out for #1! Since you are the one paying!
