I'm very surprised at the number of hours some people ranked up on there John Deere mowers. A lot of people have mower only a few years and have hundreds of hours on there John Deere Tractors. Personally, I purchased my JD X300 in May 2009 and despite using it to clear the driveway of 7 snow storms, mowing about 3/4 of grass and using it to push leaves, I've only ranked up 49 hours on the meter. It' only takes me about 1/2 hour to mow my grass maybe once every 2 or 3 weeks in the summer. How do you guys rank up so many hours on your tractors in such a short amount of time?
