Great. Thanks. I will do that.
Lugging diesels = bad or newfangled myth?

Mark, Cowboydoc is giving you good advice.

To go along with Bird's brother and the Matco truck. About well I won't say, many years ago I drove a pea combine for a summer job. I was 16 at the time. The local canning factory just got a whole bunch of new diesel tractors. Mostly International and a few Olivers. This was the first of diesels for the canning factory. Everything in the past was gas. The combines had their own engine in them. We had to run the tractors in 1st gear and at a idle. We at times would get off the tractor and walk next to it to break the boredom. Anyway after the first year all of the tractors except the Olivers had bad head gaskets. The idleing all day long evidently had something to do with it. The next year they kept the tractor in low but did run the Rpm's up a bit. I guess I kind of carry that with me to this day and I don't let mine idle unless I am getting ready to shut er down. Start up I will let it idle maybe a minute and then I run it up a bit.

You were 16 when diesels were new?!! /forums/images/graemlins/shocked.gif Did ya'all have dirt, or was it just small rocks?

With all the discussion, I am seeing that my personal definition of lugging was completely off base. By using the throttle to determine the load, I guess I have very seldom actually been lugging the engine... just pulling the RPM down quite a bit when doing work or moving. It would still speed up again with the same load if I gave it more throttle. That helps tremendously.
I do want some additional clarification on lugging when it is looked at from the opposite end of the spectrum though. If using the throttle definition of lugging, then hydrostatic tractors uniquely have the ability to approach the lugging issue from the other side. Example... a geared tractor will very seldom have a gear that perfectly equalizes a load with the maximum output of the engine. Gear 4 might be too low and engine lugs (using the throttle definition), but gear 3 not lugging and engine is able to speed up if more throttle is applied. In contrast to that, an HST tractor could be at full operating engine speed and mowing with a RFM. The HST peddle could be depressed and you are mowing along at a given speed. If your forward speed was any faster then engine cant handle it and loses RPM. HST has effectively given you the ability to equalize the forward speed and balance right on the threshold of being overloaded (and not able to speed up if you give it more throttle), but on the same token it is not losing ground either.
How would you guys classify this type of usage? This is typically how I mow when I use my RFM. Go as absolutely fast as I can without bogging down the engine.... but it sure wouldn't speed up in RPM if I gave it any more throttle.

Not Me!! I am not family, just hired help... But the current guy could pass off as one of them... With all the retro as modern stuff, our company does well, having been in business since 1946... Our newest showroom is an old gas station that is all art deco.
Sorry, I sure didn't mean to hurt your feelers - funnin' with you about yer age, and better stop sidetracking this thread...
Good subject, lugging diesels.
BTW Cummins and Benz both are adimate against extended idling. Most of those trucks sittling idling will never make our million mile club...

Mike I figured you were messing with me and that is why I thought I should take my chance and get back to you. /forums/images/graemlins/tongue.gif /forums/images/graemlins/tongue.gif
I have always liked reading your posts and am sure it will continue.

</font><font color="blue" class="small">( Thanks, no that is just when this canning factory switched from gas to diesel. The gas tractors were getting old and it was time to trade them in.
Speaking of old, by chance are you in this picture?? Nice web page though!!! /forums/images/graemlins/wink.gif

The Del Monte line or the Green Giant line? Probably GG. Sure was tough year for DM this year, peas did poorly in the weather, sweet corn got all bunched up because of the cool & 6" rainfall event, they have been running a lot of 24 hour lines this week to catch up.
That woulda been the late '60s, for anyone counting... had to be before '72 when Oliver became White... /forums/images/graemlins/wink.gif
