Yes as long as folks believe in smoke and mirrors and seemingly overlook the laws of physics.
Laws of physics? The way some folks don’t believe that the Eons known as the Carbonaceous Period stored-away enormous amounts of carbon which lowered the Earth’s temp and now Humans have been burning up enormous amounts of that fossilized-carbon which is returning the Earth to warmer conditions?
Naaahh.... Everyone can understand and believe in simple Physics!
It seems to me that we need to “follow the money” on this subject of Tier IV. When catalytic-converters were perfected and unleaded gasoline became the norm... all our lives and big-city pollution problems were significantly improved and cars became even more durable than the old clunkers we used to drive.
But first we had to endure those ridiculous air-pump/exhaust-injection system band-aids dealer-proprietary computer-diagnosis that were notoriously troublesome. Then out comes OBD and every shadetree can diagnose that the fuel cap is leaking or the number-2 Cylinder spark-ignition has failed.
We should insist that the same regulators that brought us emissions-controls should also require that systems be capable of diagnosis with simple/affordable tools for the shadetree. If a tractor mfr’r would include a simple display on the instrument panel that gave the operator the current-condition-diagnosis then that would be a huge selling point for that mfr’r over others. (One participant has already demonstrated that he chose a Kubota over a Red tractor because K obviously did it better.). That’s what all consumers do— follow the money.
The problem so-far is that different OEMs address emissions from different angles and that prevents an inexpensive shadetree tool. SideFlip has already admitted (unwittingly perhaps) that he knows the solution to Tier IV reliablity and is comfortable with it despite his previous objections: Read/Follow the manuals.
He just already has the tractors that will do his jobs for his predictable future.
What emissions-controls does is address the FUTURE problems of returning the Carbonaceous-Period to the atmosphere so our great-grandkids can live AND not blame us for killing their world prematurely. Just sitting on our duffs and blaming govt and other kids parents ain’t sensible OR christian. IMO
