The wear problems on the early engines were mostly from using kero as fuel. Starting flooded engines or from burning kero at too low of water temp and or running too rich all caused lower cylinder wear. The wear mostly happened from a heavy cast iron piston in a fuel soaked bore where the fuel is pulled down by gravity and cleans off the oil film at low rpm at first start up, not at high speed where the dynamics take effect. That fuel soaked oil stays in the compression rings a while also till it gets blown out and the piston heats up. So the age old legend may have started in the early days and carried over to JDs. Jds may not show the problem as much because sleeves get replaced at overhaul where most of the early engines didn"t use sleeves and just got new rings and piston or a replaceable block set with pistons. I have seen a lot of JDs get flooded though. My favorite green tractors are going for WAY more than JDs.. Rumley oil pulls. Those have shot so far out of reach I may never own more than a picture of one. Please do remember that most companys go bust because of bad management(sometimes a merger can be a good thing for a company), not because they are bad tractors what ever the color of the paint happens to be. Also Old tractors are only as good as the last guy who worked on them or the guy using them. I run IH H and M because I got them cheap, tons of parts around and they have foot clutches and foot brakes I need for working in the woods logging. It is nice to have a free hand to catch the low limbs flipping off the muffler before I get clobbered or knocked off. I may get a JD someday, it is not out of the question. In fact there is one down the road I have had my eye on, but it won"t get used in hill country in the woods. Seen lot of pics of tree climbing JDs. Kind of like the old unsyled GPs.
