I do remember in the "old days" before emission controls on cars that even following some cars on the road would give you a case of carbon monoxide poisoning. Others could probably fuel another car with the unburned fuel practically dripping out of the tailpipe. In the beginning, the emission controls were expensive, largely ineffective, and difficult to service. There were those nasty (read RUSTY) little tubes going into the exhaust manifolds, noisy air pumps to feed them, EGR valves that did little more than make the engine hesitate and stumble. BUT, then came the catalytic converter. You surely did not want to follow one of those for long! Talk about STINK!!! Now, we have some technology that really improves things. The 3-way catalyst is a big improvement. Not much but fresh air coming out of tailpipes so equipped. Then there is fuel injection, precise mixture control, and electronically controlled timing. Add that to multiple valves per cylinder, roller tappets, overhead cams, and a host of other formerly too exotic features, and you have a tiny engine powering a full sized car and getting decent mileage doing it! That is about where they should have stopped with the electronics. Back to the key fobs and self driving cars, just not good ideas. Period.

Today's Featured Article - Field Modifications (Sins of the Farmer) - by Staff. Picture a new Chevrolet driving down the street without it's grill, right fender and trunk lid. Imagine a crude hole made in the hood to accommodate a new taller air cleaner, the fender wells cut away to make way for larger tires, and half of a sliding glass door used to replace the windshield. Top that off with an old set of '36 Ford headlight shells bolted to the hood. Pretty unlikely for a car... but for a tractor, this is pretty normal. It seems that more often than not they a
