A few weeks ago I posted a thread about John Deere 3020 vs 4020. I got many responses and several of these had to do with possibly looking at the newer 30 and 40 series tractors. I seem to see more John Deere 4240's for sale than others. Most used prices range from $12,000 to $17,000 and slightly higher than what I am seeing on the John Deere 4020's. The show quality 4240's are in the $25,000 range and I can't spend that. I'm looking to be able to run a modern discbine and maybe even a larger 20 ft disk eventually. My question is do the 4240's have a good reputation or should I look at another 40 series tractor or 30 series tractor ($15,000 is as high as I would like to spend and around 100 hp is what I'm also looking for.)
