I have just purchased a John Deere LA115 lawn tractor from a dealer in Long Island NY, I am in the west of Ireland. I am getting the mower in with duty and shipping paid for 1850euro, the same machine over here is nearly 4000euro. I have heard I will have to change the spark plugs as we use a different mix petrol...any ideas if this is true. A friend is getting a X300R all in for 3200euro, it retails here for 5700euro, why would anyone buy at home. Even with sterling/dollar conversion they must be a lot cheaper across the pond.
