I don't really know anything about tractors, but I recently visited our family farm and was looking at one owned by my great grandfather. I noticed on the instrument panel there is an hour meter, but I don't really know how to read it. It says "Hours at 1580 RPM" and the readout is 6765. I was wondering what this converts to in terms of maybe miles traveled or something. Is it just the number of hours spent on the tractor or what? Is it somehow related to what gear you're in while driving it? Please shed some light on this.

As to the gauge, it is geared to the engine crankshaft and basically counts the number of revolutions of the engine. If that tractor would have been run at exactly 1580 rpm all the time, it would have run exactly 6765 hours. Ovbiously sometimes you run at full rpm, and sometimes at idle.

Tractors do a lot of pto work standing still, and run in different gears. You can't really judge 'miles' on a tractor, you have to judge 'hours'.

The others give a good approximation. A tractor probably needs a rebuild somewhere around 5000 hours, a really well cared for tractor can go 10,000 hours. Just as a car can go 150,000 miles before it's used up, some can go 300,000 miles....

As a rule I multiply hours X 30 to get equivilant miles. Tach hours are not actual, depends on RPM tractor has been operated at.

Sure that you multiply by 30? Shouldn't it be 3?
