1100 hours is way too low for a '68. Likely the tachometer cable corroded off 20 years ago. It should be in pristine shape for those few hours and the tires original (probably hard but hardly worn). I'd pull the rocker cover and check the rocker oiling while setting the valves on either engine. The cork plugs rot with age, not with engine hours. I'd look at the spark plugs (while replacing them) to see if any were sooty or oily. 6000 hours to as much as 12000 hours is typical from the average farm tractor at rebuild time. More go longer than shorter. However failing to notice an oil leak can kill any engine in a couple hours. The tachometr on my 135 shows 5000 hours or so. The rear tires died of old age. I think I've put a couple thousand hours on it since I bought it about 1987. Some years plowing, preparing, planting, and baling 24 acres of ground, I ran it 100 hours a year. Lately I've cut back on earth work, but gone back to using it for spraying and planting only using the 4020 when I need crop clearance for spraying. I know my tachometer cable has failed once since I've had the tractor. And there are no laws against setting the hour meter back on a tractor. Except for rot of old age, a 1100 hour tractor should look like its still in the showroom. Gerald J.
