Like other owners of John Deere lawn tractors, I thought I had purchased a quality product that would last until I decided to quit mowing my on lawn. I have taken good care of this mower, cleaning after each use, changing oil regularly etc. etc.
This year it would not pull an incline after 30 minutes of use. Thanks to this forum I have learned that these units have a non-serviceable trans axle, which doesn't last as long as it should.
