Ray, I like the idea of making charcoal briquettes out of it! Or if we could just use the excess heat in the regen for something or maybe like an afterburner on a jet engine use it for propulsion! That's what we need a jet propelled tractor!
Dave, I think from bitter experience the gov't knows that too many people have no common sense, and worse yet, just look at the numbers of posts from people who want to defeat the system before they have even tried it out much less had trouble with it on a tractor. I think 90% of the problems that have occurred in these compact tractors are where the computer, the all knowing computer, doesn't let the system regenerate because it doesn't think some parameter is just exactly right, and instead of letting the operator solve the problem it shuts the tractor down. It knows many of us would put off solving the problem until we just finished the job at hand and maybe the next one...in the meantime either the catalytic converter would be ruined or we'd be emitting over the allowed amount of pollutants. I really hate not being trusted to do things right, but I can see where it comes from.
I should point out to be fair, that I have had, knock on wood, not a particle of trouble after a year of anything but optimal use for a diesel. It starts like a dream, no block heater, runs quietly (this is thanks to the computer controlled common rail fuel injection system), and has regenerated when needed with no trouble. The fuel economy is great from my point of view. The electronic controls on the fuel injection system sound like a step forward, power and fuel economy. However, some folks have rightly pointed out they may be a pain to fix down the road. We'll see, keep your fingers crossed for me.
