What are hours on a tractor

The only real way to tell is to turn on the key and see if the hour meter runs or it remains the same. 1/10 hour on the meter would be 6 minutes so it wont take long to see if the clock registers real time or engine PTO speed time.[/QUOTE]
I will do that today.

just turn the key on without starting and wait a while and see if hour meter moves. most manufactures i bet only hook the meter up to the ignition key because most people don't leave key on only! not exact science you know!

Hr meter reads 746.9
So at the advice of some people here I turned the key to on and left . Came back in 13 minutes
Hour meter reads 746.9hrs still.
Started the tractor left again to get more work done. Returned 24 minutes later
Now it reads 747.3.

So not sure where the 746.9 was sitting so will round up to 747.0
Not sure where the 747.3 is as it may be ready to roll to .4 or maybe it just started at .3
Worst case is the hr meter rolled .4 in 24 minutes so I would think that as soon as the tractor is started the hour meter runs full time . Not dependent on the RPM.

What about when the pto is not being used?

I think some older tractors had the hour meter tied to engine speed. On every machine I have ever owned the hour meter counts true time regardless of if running at idle or wide open throttle.

There was a very good discussion about this month or so ago on here.

I always thought a mechanical meter, that is one ran by a speedometer cable, reported hrs based on engine speed. So it was accurate at PTO speed, off otherwise. And that an electronic meter was just a timer, key on keeps track of actual time key is on.

But I was educated. There are actually tractors that have what I call Smart electronic meters and can't be tricked by leaving the key on. Sounds like that's what you've got. I've never checked my electric meter on the Kubota. But my old 1984 Ford is mechanical. You can idle around all day and maybe clock 2 hours.

Most Electronic meters an hour is 60 Minutes, (Measures Time) Most mechanical Meters an hour is PTO RPM x 60. (Counts revoutions)

With an electric meter it will read (count) with switch 'ON' and engine off or not running.
That is unless it is oil pressure activated as some would be.
After all it is merely an electric clock.
