Conclusion

As a John Deere 8 Series tractor owner, I have been disappointed by the number of problems I have experienced. The most common problem is the transmission, which has failed on me twice. I have also had issues with the electrical system, the hydraulics, and the engine. I am not alone in my experience, as many other John Deere 8 Series owners have reported similar problems. I believe that John Deere needs to do a better job of quality control in order to produce tractors that are more reliable. In my opinion, the John Deere 8 Series is not worth the money, and I would not recommend it to anyone.
