Zebra, you are correct, the 03 series are not made in the USA. However, as Rolling Farms points out, the quality control is all Deere. I worked my dealer and several others very hard about quality before buying our tractor. All of them had good things to say about the 03 series, especially since I was giving them the option to sell us something else.
With regard to Rolling Farms' point of weight ratio, he may be right and it is probably something to consider. My point in my earlier post was simply a cost to use ratio. It sounds like Zebra is going to use his tractor like I use mine, for a piece of hunting property and it may see limited use. One of the few complaints of my tractor is the skinny tires that will sometimes spin in dry conditions. The 5103 has the skinniest tires of the 03 series. The cost of new wider tires (which would require new rims) was not worth the upgrade to me at this time. Again, purely a cost vs. use issue. I'm sure R Farms uses his tractor a lot more than I use mine. If I were using mine more often, I would have most likely gotten a 25 series.
As far as the paint fading on the rims, I can't see where that alone would justify another $10,000 to move to the 25 series. I have a hard time relating rim paint quality to the quality of the entire machine. A $5.00 can of spray paint fixes that problem. If you are going to use your tractor similarly to how we use ours, I would suggest looking at the 5303. Good luck.
