Ok to start off, I am not here to insult anyone or put down their tractor. I am quite sure the X5xx series is more then capable in doing what it was designed to do. But you have to admit that some tractors are made better then others.
First, the GX345 was selling for $7500 in 2005. Pretty much the same as the comparable X540 is selling for today. With inflation factored in and the high price of steel today, how would it be possible to build the same quality machine for the same sticker price 6 years later. It just isn't.
According to my JD salesman, who I have been dealing with for more years then I can remember, I would be crazy to trade my GX345 in for the X5xx series. He said the GX line was way overbuilt and is one of the best used L&G tractors, on the market today, for the money.
Unfortunately, I need 4 wheel drive, so I will have to soon part with it. If I can't find a near new X595, I guess I will have to go for the X7xx series
Once again guys, I am not an engineer or even a mechanic. My opinions are based on just what I've seen, read and told by my JD dealer. But you have to admit, the sales price of the two machines 6 yrs apart, says something.
