Working the Curve

College kids...they present quite a challenge to us old fogies....we want to be able to converse with them as if we actually knew what we are talking about and sometimes that ain't easy. When I had offspring in Animal Science, Anthropology and Fisheries and Wildlife, the learning curve for conversation was fairly shallow. They brought home veritable fountains of fascinating new information but at least I had a foundation upon which to build my knowledge. I have lived animal science since I could toddle around with puppies and kittens. Anthropology is just history with science thrown in. Fisheries and wildlife, yeah, fish and fascination, I could do that. I already knew half of those tough Latin names from another college experience in another life time...and from learning them just for fun.

Then along came Agricultural Engineering, which is a fancy name for Diesel Technology. Suddenly the curve looked (and sounded) like Everest on a bad day. I more or less, kinda, sorta, get it about gasoline engines, having dated a mechanic back in the day, and having driven a lifelong series of clunkers (without cash, alas) which taught me just about every single thing that could go wrong with one... Diesels, not so much. I can drive a tractor, but my knowledge stops right there, and that is just fine with me. I like Esox and Sylvalagus, phooey on injectors and turbo chargers.

However, to survive the nightly after-class sermons in the barn I have been forced to learn things I didn't want to know. I now know what a common rail is and can draw one on the barn blackboard. Pumps, bench tests, PTO horsepower. I can listen to all that diesel-Greek with the best of them (I won't lie and say that I get it yet, but I guess I am going to learn whether I want to or not).

Now the turbo charger on the 4490 has gone bad and the kid is trying to replace it with the one that came off the engine that the same tractor blew a couple of years ago. With all the men clustered around that tractor all through milking last night and Becky making pancakes so we could test drive the new grape jelly, Liz and I ended up milking pretty much alone....fun, fun, fun. Will all that classroom learning bear fruit and the tractor arise from the dead, yet again? I surely hope so.

In the meantime let me draw you a common rail.
