Emission control suit of requirements (both hardware & software) make these tractors failure more likely. Eg. from a youtube farmer in Sask, Ca., his NH tractor wiring harness failed because highly corrosive DEF was puked all over it. Wiring hardness is only needed to fine tune injection pump & the pletora of sensors because of regulations, and DEF is only needed because of regulations.
All of this decrease the useful lifetime of equipment.
And no, all of this is not required, a trucked was able to pass California regulations with an old pre-EPA-regulations diesel engine, but the tolerances are a lot tighter (ie. forget about that chinesium oil pump with a couple thousands too much shaft end play), maintenance is a lot trickier...
- olyjohn 5y agoReminds me of when Honda designed and installed CVCC cylinder heads on a Chevy 350, and were able to get those engines to pass the 70s emissions standards without a catalytic converter. Instead the EPA ruled that all cars must have a catalytic converter, even if you could figure out other ways to pass emissions. Must have taken a lot of pressure off of the US automakers at the time when smarter, smaller imports were starting to gain popularity.
