Got a unsolicited call from my local JD dealer today, same one I bought my 2520 from. He wanted to know if I wanted to trade my 3 year old machine for a new one. I initially said no, why eat the initial depreciation now? He said I should look at what he could offer. They offered to take my 2520 with 370 hours, my 62D mower deck, and any two implements I own and replace it with all new machinery for $500 out of pocket! I still can't believe it. When I think about the cost comparison for keeping my "old" machine it would be stupid not to take this deal, right? I have about $200 in repairs to make on my machine due to minor "accidents", I probably need a new air filter soon, I have one tire leaking that needs fixing, I'm due for an oil change, and my deck needs new blades. I figure all this will cost me nearly $500 over the next year. Plus if I do the trade I have a new machine with new warranty. Why wouldn't I do this? Anyone else run across this offer? Sounds too good to be true.
