Tom, I'm not sure I understand you correctly. My Ford 8600/9600 tractors register a clock hour on the tach at 1666 RPM according to the owners manual. Dinking around at 1200 engine RPM I'd say it takes almost 2 hours to put an hour on the tractor tach. Running flat-out at 2300 RPM the tractor tach will run up an hour in about 45 minutes.
