I just watched a piece on classic tractor fever (RFD) about the UDLX, which has been real popular on these pages of late. Been lovin the pictures, the history of so many that I still can't believe got tore up so bad. Truly an amazing piece that was so far ahead of it's time. Hence my question: is the UDLX the most collectible tractor ever, regardless of color or brand? I know that there are some out there that are the one & only survivor of their make, model, etc. so to me they would be priceless. I'm thinking about tractors that are rare, but still enough of to be acquired if ya got the bankroll to do so. Just wondering. DP
