"maybe it is a regional thing, but lightly used tractors in my area hold their value very well. "
Could be....Nate doesn't mention where he's from..just that he's going to NC.
Biggest problem is a low hour used machine competes with new units. Nate's machine is 4 years old (2000/2001), so even with comparatively low hours, it's definitely not new. It's most likely out of warranty as well.
I just bought a 2003 Deere 790 w/ 419 FEL. There were 24 hours on the tractor when delivered. In southern PA, the new list is about $15,000 give or take $500. I bought it for $12500 from a dealer in southern Virginia. That's about a 15% depreciation in a year.
Now...here's the funny part...
I traded a 1991 Deere 670 for the 790. I got $7000 for the trade in value. When I bought the 670 three years ago, I paid $8500 for it and a 60" Befco RFM that was only a year old. The Befco wasn't part of the trade for the 790.
So, there was about 18% depreciation for those three years...if we ignore the value of the Befco.
Now, here's how the dealer that took it made out. He sold that little 670 for $8000. He made a thousand on the deal. The buyer purchased the 670 for what I paid for it (although, the Befco was probably worth more then $500 when I bought the 670).
So...I would say that our tractors depreciate 10% to 15% for the first few years, then level right out and hold their value (of course, hours and condition would also be factors, but for this discussion, let us say good to excellent condition applies). This is based upon my recent purchase and a fair amount of research when I was looking to upgrade from the 670. Just a bit more info...the 670 cost about $11500 new (1991 price). Since it had a loader, I suppose we could add another $2500 to that $11500. So, when I bought that 10 year old 670, it had depreciated about 40%. Not too bad...
BTW, I'd estimate Nate will get between $9000 and $10500 for his Kubota.
