Operating hours

[JDgreen227]

I had a similar question I asked here as well...

http://www.tractorbynet.com/forums/owning-operating/17367-covert-tractor-hours-miles.html

Thanks...just read that discussion...I wondered if there would be any "real" answer to my original thread but it appears that there are so many variables involved it cannot be calculated properly, thanks to all and I am going to discuss these replies with my nephew. He is a math wizard so they will make more sense to him than me...

When you all have this figured out I have another one for you that is the same. Consider a cow that produces milk from march to Dec compared to a work horse that is used from Mar to dec, possibly from maple syrup through all crops to hauling wood. Which one is working the hardest. Consider also what that work is doing to the animals condition.

I'm sure if you asked the horse he would say all the cow did was eat, crap and get her teats played with twice a day...

That is easy to figure, the cow does nothing but chow down and swish it's tail and get milked. The definition of "work" is as follows: "Exertion directed to produce or accomplish something", well that is the primary one. Does the cow have to actually do anything to produce milk except eat and digest? Witness the poor horse, pulling heavy loads while the cow loafs around chewing it's cud...sorry, to me this is a no brainer.

Maybe if the cow was running at pto speed (about 2450 rpm) while operating three milkers and the horse was galloping uphill at 35 mph in a headwind it would be harder to calculate which animal is working the hardest....

Well, suppose the service life of a well maintained car is 250,000 miles and that of a well maintained tractor is 5000 hours...would that make sense? If so, that equates to one operating hour on the tractor to being 50 miles of use.

I think the tracor hours are too low there , most farmers that keep a tractor to the end end expect at least 10'000hrs from it, very normal for fleets of tractors to clock over 2000hrs per year .

Years ago I had a manual for a Winco generator that ran at 1800 rpm. The manual stated that at 1800 rpm, one hour of run time was equivalent to 40 miles. Since then I use that as a rough estimate for engines. I think that is close enough for government work.
Happy and Prosperous New Year to all.

The old 1959 MF65 I sold a couple of years ago, had 11,000 hours on it. It started and ran great but was only 2WD. Didn't smoke or burn any oil - though I am sure the engine must have been rebuilt in it's life time. I know the head had been overhauled - not sure on the engine. All I have done to it was a complete fluid change (hydraulic, transmission, engine oil etc.), adjusted valve clearance, new spark plugs etc., new oil filters and it ran like a champ.

I think a lot of people forget that the tractor might only be doing 3 or 4 mph but at say 2300RPm or more - especially when using the attachments.

I suspect the design criteria would be a bit different to that of vehicles or generators - but no matter what, they still need proper maintenance.

Thanks

Another variable would be hours spent idling on police vehicles. My son bought a beater Suburban to tow his track car. It had about 180,000 km, but the dash showed 5700 hours. It was an RCMP canine corps truck before it went to Crown Assets. The truck worked well and there wasn't anything wrong with the engine once he bypassed the flex-fuel detector

Amazes me this thread has a new post after being idle for so long. It's not only police and emergency vehicles that get a lot of time spent idling, but also delivery vans doing a lot of start/stop cycles and medium duty trucks that are stationary and using the PTO to run a liftgate or dump body. I may be wrong here but I'm thinking that newer vehicles with very accurate computerized fuel delivery would generate less engine wear from frequent idling than older models would.
