Hour meter operation??

[DK35vince]

Both my Kioti DK 35 and John Deere 850 are tach based.
Need to run 2000 RPM for 1 hour to register 1 hour.
My zero turn has the clock type meter (turns on with the key).
I seems to me like on the clock type meter the hours add up faster than my tach based meters.

I'm not sure what you are looking for.. you have described both the electric 'clock' style meter and the rpm based mechanical meter.

That is just what I am looking for...examples from those in the know how their particular tractors or equipment record the hours.

So far there doesn't seem to be a consistent pattern. Some tractors record "clock on" time while others have the RPM timer style - even with the same manufacturer. Others have stated that their equipment has both. It would be nice if manufacturers would label the meters. On the other hand - does it make that much difference?

I can see where the RPM style would better reflect the wear on the engine but neither style takes into account the load. One could be pulling a plow at fairly low RPM but putting considerable strain on the engine.

The bottom line seems to be to service the tractor regularly while taking into consideration its use as a factor. The hour meter is more of a reminder.

When buying a used tractor it is evident that "hours" remains the Holy Grail of evaluation. Now it is clear that "hours" can mean entirely different things.

. It would be nice if manufacturers would label the meters. .

why.. it's easy to check.. look at the meter.. do some work that doesn't require constant pto rpm speed.. which is where many rpm based units record 1 hr... do 1 hr work.. look at the meter again... if it says 1 hr.. it's a clock.. if it has a different number it's rpm based.

. On the other hand - does it make that much difference?.

depends on what you are recording the time for...

if for rental.. then the renter usually wants clock hours. if for oil change or air filter.. then rpm hours may be a better choice.

. I can see where the RPM style would better reflect the wear on the engine but neither style takes into account the load. One could be pulling a plow at fairly low RPM but putting considerable strain on the engine..

load can better be seen on an rpm meter.. a clock style just says yer key is on.

pulling a plow you likely are not idling... least I've never been able to idle while breaking ground..

. The bottom line seems to be to service the tractor regularly while taking into consideration its use as a factor. The hour meter is more of a reminder.

well.. that's what it's there for. In haeavy or extreme conditions.. you will liekly want to check and service more often.. especially the air filter in dusty conditions..

Both Kubota's that I own go by pto speed. For example: if pto speed is 2000 and the engine is run at 2000 rpm for 1 hour the hour meter will log 1 hour on it. If the engine is running at 1000 rpm, it will have to run for 2 hours to log 1 hour on the meter.

The real question is "why not"? Clear labeling would clear up any confusion. There are labels and warning for just about everything else.

On older farm tractors, the meters that read hours biased by rpm were called TACH-HOUR METERS. And the tach was labeled as such "TACH-HOURS".

and you want more consumer protection labeling? really? really?

What about the manual... old ford proofmeter docs tell you how they work.. I would bet some others do as well... easier to put it int he manual ( that most don't read ).. then to have to put a lable on every gauge explaining how it works....

What was that song, from 1970? "Signs" by Five Man Electrical Band

"Sign Sign everywhere a sign
Blocking out the scenery breaking my mind
Do this, don't do that, can't you read the sign "

and you want more consumer protection labeling? really? really?

What about the manual...

Lets have both, then you will know if the hours where put on with lots of idling or lots of wide open throttle.

On the 399 if you shut the key off it doesn't count any hours.

When did we get the new smilies? I like 'em. :thumbsup:

Kubota BX2200 uses an electric clock; if there is power, hours are running, even if the engine is off.
