My school bus which has a 6 cyl turbo diesel has 73,397 miles on it and 3,131.3 hours. That comes out to 23.4 MPH. But I think most tractors figure hours based on engine speed not just clock time. Not sure how its figured in the bus.
If I could find one, I would be interested in a larger size construction backhoe with 2000-3000 hours on it. Still plenty of life in it for my use.
This is somewhat interesting because the last pickup truck I bought actually shows me the hours as well as the miles. It turned over 1,800 hours right at 80k miles. I guess that works out to be an average of 44.44 mph average speed when it was running? I've never really thought about it before nor if it has any bearing on anything.
It's a 2006 Ford F350. I bought it used and the previous owner had a daughter who competed in barrel racing on horses. They buy a new F350 every 2 years. I'd have to assume that most of the miles were on the highway but that would only be an assumption. With me it's probably close to an even mix with possibly more in the city. It may have been closer to an average of 50 mph and I brought it down in the last 8k miles I put on it.
Do a lot of diesel pickups now show the engine hours? I generally keep my pickups at least 10 years and obviously my last one didn't have anything on it telling me the hours. I was honestly surprised to see the "engine hours" show up when scrolling through the onboard trip and diagnostic program that came from the factory on the truck. It's highly likely I'm just behind the times and most newer diesel pickups have such. I don't know.
