So? They gonna come to your house?

They better have 4WD with plenty of ground clearance. And they will probably get lost. That's how people usually show up here.

Sure they will. Already do, in some states. Haven't you been reading any of Ultrarunner's posts about life in California? If it becomes National policy then whatever Texans prefer won't matter.

We'll see about that

New Administration, New Rules, New Sheriff in Town --

AI sez ~

New EPA rules, announced in August 2025, provide updated guidance on Diesel Exhaust Fluid (DEF) systems for nonroad equipment like farm tractors, aiming to prevent sudden and severe power loss in case of malfunctions. The guidance mandates that nonroad equipment must operate without power loss for at least 36 engine hours after a DEF system issue, followed by a 25% and then 50% torque reduction over time, with limited engine restarts allowed. This aims to increase operator confidence in the equipment while still encouraging emissions reductions.
Impact on New Diesel Tractors

• Less Sudden Power Loss:New diesel tractors will be designed to run for a longer period, up to 36 engine hours, before experiencing a significant power reduction if the DEF system malfunctions.
• Phased Torque Reduction:If the DEF issue isn't serviced within 100 engine hours, the tractor will then experience a 50% reduction in engine torque.
• Limited Restarts:Operators will have the ability to restart the engine with full power for up to 30 minutes, three times, after a DEF malfunction occurs before the torque reduction takes effect.

What This Means for Farmers

• Reduced Downtime:Farmers will experience less immediate and drastic disruption to their work if a minor DEF issue arises.
• Increased Confidence:The guidance gives operators more time to diagnose and service the equipment, reducing concerns about equipment becoming inoperable.
• Potential Removal of DEF Systems:Some experts believe this change could signal a move away from including DEF systems on future farm equipment, although this will take time.

Context of the Changes

• Addressing Operator Concerns:The new guidance addresses complaints from farmers and truckers about the severity of power loss and engine derates caused by DEF systems.
• Manufacturer Collaboration:The EPA developed this guidance in collaboration with manufacturers to provide clear direction on how to implement solutions for existing and new diesel equipment.
• Balancing Regulations:The EPA is continuing its efforts to reduce pollution from diesel engines while ensuring the reliable operation of these crucial pieces of machinery.

Yes, and in 4 years when Governor Newsome becomes President Newsome those pollution controls will come back, only be much harsher. (Enter your favorite tree-hugger's name here) Then what? Are we going to have to install DPF/DEF systems on all tractors, new and old, to be able to run them?

Don’t wish that kinda stupidness on us.
Future moron politician is going to emissions test your tractor , lawn mower, generator?
Test the GPM’s of your toilets
Check your faucets for aerators?
Your showers for water restrictors?
Your gas cans for vent caps?…etc….

They would if they thought they could get away with it.

I want my old Gas Cans back. The new ones that are supposed to save us from ourselves end up leaking gas all over everything and do way more damage than the old vented gas cans.

Yes, gas cans can have vents again as of July 2025, with the U.S. Environmental Protection Agency (EPA) clarifying that vents are allowed if they automatically close when not in use, a change made to improve fuel flow and usability

Yup. Hopefully none of us dump our oil or even tolerate a bad leak. But as far as I'm concerned there is way too little attention to blatant issues not/never addressed. Or misdirected policy like ethanol percentages (or MTBF bwahh-hahhh). There is so much that could be done but it doesn't make the greenies as happy because they are not the hot button issues of that day.

Ethanol is a crime. The costs to produce it if you include all the farming costs... all using diesel, then transportation costs... more diesel, then the refining.... more energy consumption.... then transfer and blend.
And at the same time depleting farmland.
What a joke.

Don't forget raising livestock feed prices by a lot.

And it’s subsidized.
