Tractor Hours

Nedd · Jul 18, 2008

I was scanning through articles on here and saw there was an old one on tractor hours. I've worked on older Case tractors where the majority of the tachs run off a gear/cable assembly to the cam.
My question is do newer tractors with electronics keep track of running hours like a watch? Or do they still go off of RATED RPM hours?
If you run a tractor for 1 hour, that was rated at 2000 rpm but you only ran 1500 rpm, Would you end up with 45 mins of run time verses the full hour?
Just curious.

The 1989 Case IH 7110 that I had was clock hours.

Most new units count clock hours.. i.e. engine running wether it be full throtle or not.

Most with mechanically driven tachometers with hour meters ar calibrated at PTO speed. So when you run the engine slower, hours take longer to accumulate, but when you run it faster hours accummulate faster. Since the main reason for the hour meter is to show maintenance intervals, that works out because slower speeds aren't working the engine as hard. It can be a problem when collecting rent by the hour, but then its never been hard to add a purely electric hour meter that runs when the power is turned on.
