I have personally seen where these “clean” emission tractors and combines consume way more fuel than older models. Also I’ve seen exhausts get dangerously hot from the regeneration cycle to clean the DPF filters. It’s not necessary or safe considering the amount of time these types of equipment sit most of the year when not in use.

This has never made sense to Me , By the time We mine Export and use all the steel and material to build these , All the employees who drive to the factories to build them and design them , By the time they make the DEF and haul it all over the US , All the plastic that is used and cardboard for 1 jug at a time We have more then doubled the pollution that it was intended to save

I manage the service dept. At a caseih dealer, tier 4 engines are the most expensive, and biggest nitemare we face on a daily basis. They are not efficient, and definitely unreliable.

Tier IV emissions for ag equipment is unnecessary regulatory burden on the community. Majority of your AG Equipment runs less than 300 hours per year unlike vocational equipment.

Please roll back the emissions standard... the cost of the current standards as far as cost of equipment, maintenance, and diesel exhaust fluid is placing an unbearable financial strain on my farm. Please roll back to pre -day, and pre particulate filters immediately. Sincerely, David Templeton II

Works when it’s new doesn’t work when it’s used. Emissions cost the farmer more than it’s worth. More breakdowns resulting In poor engine performance. Oil and fuel leaks all over the engine going on the ground and lots of def containers for me to burn. Costs the farmer money and doesn’t help the environment.

I agree totally. It is too much of a burden on farmers
