Hey, I've got a 1977 JD 210 garden tractor that I am using to mow and plow snow in the winter. Mine needs an engine overhaul as it burns oil pretty good, but when it is running, it's great. I bought a copy of the service manual, on ebay I think, and it has not let me down yet when it comes to fixing something. I just bought a Kubota BX25 in February to mow the bigger areas, but haven't yet run out of projects for the FEL and backhoe so the mower hasn't been used yet. The JD will still be needed for the areas around the house, under some dwarf fruit trees, and a couple of narrow spots so maybe I can get it to last as long as I do by giving it a reduced work load. Maybe I'll buy one of those rebuild kits for the engine and give it a shot or if I'm not feeling so adventureous, have the engine professionally rebuilt. It should last practially forever.
