mileage vs hours

mike paulson · Dec 25, 2010

first off, Merry Christmas folks!!!
anyway while i sit here alittle bored smelling the turkey roasting i was wondering. i'm a lifelong truck/auto mechanic and was wondering how hours on a tractor compared?relate to mileage on a truck or car? i mean is 3000 hours on a tractor alot, is it like say 200k on a truck motor? is a tractor with 6000 hours pretty much in need of a motor rebuild? just wondering.....thanks

If you drive 50 miles per hour, then 50 miles would equal 1 hour. You can do the rest of the math.

A lot depends on what the tractor was doing for those hours and how well maintained it was. I don't know about any else but I can easily go 200,000 miles on my vehicles and not need an engine rebuild. Take care of your equipment and it takes care of you.

One way to look at it is there are roughly 2000 hours in a working-man's year. (8 hr/day, 5 days/week, 52 wk/yr less 10 holidays & 2 wks. vacation)

Another way to think about it is piston aircraft engines in light planes usually have a manufacture's TBO (Time Between Overhaul rating) from 1200 to 2000 hrs, with the more common engines being around 1600-1800. Consider that an aircraft engine spends most of it's time at full or near-full power (70% cruise) and gets serviced every 100 hours (oil changed). It has the advantage of seldom running in plowed ground, hence less dust going into the engine

There is no perfect formula. A well-cared for tractor engine can often last 10,000 hours between rebuilds. A car or truck engine - pick a number - but I'd guess 150K - 200K. Not so easy to pick an average number with cars and light trucks since they change hands, get scrapped before the engines go, etc.

2000 hours on a tractor would be close to 100,000 miles on a truck or car, that could be adjusted for a tractor with a very hard or very easy life.

my 2008 f-350 has just over 40,000 miles and the truck computer says it has 1312 hours.

To complicate things, there are two types of hours:

1. ENGINE hours
2. OPERATING hours

You gotta know which one the tach is recording.

The old mechanical tachometers record engine hours, and it depends on how fast the engine is running what an actual "hour" is. 1 hour at PTO speed records as 1 hour.

My take is that 3000 hours on most gas engined tractors is getting up there.... that many (or few) on a diesel is next to nothing. This of course is assuming reasonable care.

I'd bet there is a difference between the cast used in tractor engines and the car engines nowadays are mostly aluminum, same for aircraft. Give me cast for longevity anytime.

I was always told to take the hours times 50 to get the miles equilavalent to hours . Dad always said that and he was a red mechanic for 40 yrs.
