It's going on 2 years with my X485 and I am debating whether to pay the $300 or so and have the dealer do the maintenance or buy the home kit plus antifreeze and do it myself. I did the tune up last year no sweat but not particularly thrilled about flushing the cooling system. The tractor has about 80 hours on it with no starting problems. I have not been very happy with the JD Mow and Go program where they bring the trailer to your house and do the maintenance there. I thought they did a better job when they took the tractor to the store and did the maintenance there. What are some of your thoughts pro and con about which way I should go.
