Recommend Tractor Upgrade From My Ford 4000

I don't believe so. Last I knew tractors under 70-80hp were still exempt from the emissions bullshot

I'll have to alert AOC of this finding, she'll fix this issue! Lmao

If you have never been, this auction is fun and lots of tractors at good prices.

I don't think that's true after 2014 or 2015. My dad was looking at a 2013 (IIRC) Kubota last summer, and the dealership was putting a reman in it; they were originally going to put a new engine in it, but the newer engines had the DPF emissions crap on them.

Then again, I think that was a 70 horse tractor, so you might still be right.

I very well could have been wrong. There was something up with emissions requirements and hp I know. Maybe it was something like the smaller tractors only had dpf and the larger ones had a dpf and def system. I know the emissions systems were in tiers. There was something. I'm just confusing myself now.

I didnt look around very long, most recent article I found. Seems some manufacturers smaller diesel engines are efficient enough without out the DEF and DPF, and some just still need the DPF.

What Are Tier 4 Diesel Engine Standards And How Do They Affect You?

Wade Wessler | June 28th, 2016
What are Tier 4 Diesel Engine Standards?
Currently, Tier 4 diesel engine standards are the strictest EPA emissions requirement for off-highway diesel engines. This requirement regulates the amount of particulate matter (PM), or black soot, and nitrogen oxides (NOx) that can be emitted from an off-highway diesel engine.

Based on an engine’s horsepower rating, Tier 4 requirements were phased in starting in 2008. By the time final Tier 4 regulations were fully implemented in 2015, PM and NOx emissions had been reduced 99% compared to 1996 levels.

Are there any exemptions? Yes!

Tier 4 regulations exempt engines under 24 horsepower. There are some additional off-highway diesel engine exemptions that affect specific markets.

• Engines used in railway locomotives, those are subject to separate EPA regulations.
• Engines used in marine vessels, those are subject to separate EPA regulations.
• Engines used in underground mining equipment, these are regulated by MSHA (Mine Safety and Health Administration).
• Hobby engines (below 50 cubic cm per cylinder).

How to Meet or Exceed Tier 4 Diesel Engine Standards
Through advancements in engine design, modern diesel engines have been transformed into one of the cleanest prime movers available today. Some of these engine improvements include high-pressure common rail fuel injection systems, electronically controlled injector solenoids, and advanced turbocharging. While these improvements enabled engine manufacturers to meet Tier 2, and Tier 3 standards, in order to meet the more stringent Tier 4 interim and Tier 4 final regulations, exhaust after-treatment was required.

There are three major technologies used for exhaust after-treatment.

• Selective Catalytic Reduction (SCR) - This works by combining the exhaust gases with ammonia (urea or DEF, diesel emissions fluid) and passing this mixture over a catalyst. Roughly 1 gallon of DEF is required to treat 20 gallons of diesel fuel.
• Diesel Particulate Filter (DPF) - This works by using a mechanical filter to trap soot particles after they have been partially oxidized by a catalyst. At certain intervals during operation, the trapped particles are incinerated.
• Exhaust Gas Recirculation (EGR) - This works by recirculating a small amount of cooled exhaust gas back into the combustion chamber. This reduces the combustion temperature and effectively reduces the production of NOx. However, EGR increases particulate emissions, so a DPF will be needed to meet Tier 4 final regulations.

Tier 4 Diesel Engine Standards And Electronic Controls
Lastly, the one major component required to meet Tier 4 standards is a sophisticated engine control system. This control system is housed in the engine control unit (ECU). This manages dozens of operating and environmental conditions in order to optimize horsepower, torque, and responses to changes in load. It allows the engine to maintain combustion efficiency over a broad range of operating conditions and minimize emissions in the exhaust. All engine parameters are communicated from this control system (ECU) over CANbus J1939 communications. Examples are pressure, temperatures, regeneration requirements, and engine faults.

How Tier 4 Diesel Engine Standards Affect Machine Builders?
Here are a few examples of things that need to be considered.

• Physical size of the Tier 4 engines are, in most cases, quite bigger than previous Tier engines. The reason is that you typically now have an after-treatment system (DEF tank for example) and larger heat exchangers (radiators), as well as changes to the filter systems, turbocharger, and other engine components.
• Because of some of the physical changes, machine builders typically have fewer engine mounting points and fewer coolant ports.
• Typically, a bigger engine is needed to get the same horsepower rating as a non-Tier 4engine. One of the reasons is that some of the horsepower is used to drive functions like the fan drive for cooling the engine.
• Because Tier 4 engines run hotter, this affects wiring and other components in an engine compartment. Heat shielding is often required to eliminate this as an issue.
• If your vehicle utilizes different manufacturers of engines (some customers specify certain engines be used on their vehicles), each engine manufacturer’s Tier 4 engines are a little bit different. Not only physically, but how they operate, how they regenerate (regen), their horsepower ratings, and how the controls interface and function.
• When certain engine conditions are met, such as when a regen process is required, the engine will automatically go in a “derated” mode. This derating typically takes on the form of a reduction in rpm, and a corresponding reduction in power. This can sometimes be delayed or adjusted, but this needs to be discussed with the engine manufacturer.
• With the sophisticated engine control systems on Tier 4 engines, if you are using this as your prime mover, you must be able to communicate with the engine ECU through the CANbus J1939 bus. This can be part of an engine specific display or can be added to a larger vehicle body control system and its display.
• After-treatment specific indicators must be added so that the machine operator can visibly see all operating conditions. This includes a regeneration indicator, high exhaust system temperature indicator, regenerations disabled indicator, DEF indicator, and a DEF level gauge. Again, this information is communicated through the ECU via CANbus J1939 bus. This can be part of an engine specific display or can be added to a larger vehicle body control system and its display.

Just saw this today. I'm not pushing Kubotas. I'm watching this never had a tractor guy and the very talented and well versed salesman teaching the potential buyer all the features of the tractors he's looking at.
It is a great video. I even learned some things.

I like Kubotas, but I can't afford 'em, aside from the wee baby 20hp-ish diesel I got from my dad to mow my yard. From what I understand, Kubota is the only manufacturer who still engineers and builds their full line of tractors, from the little lawn tractors and ZTRs up to the big jobbies.

anyone have experience with the Ford 4000 tractor? My cousin has one with a front end loader he said he would sale for $4000 and I might even be able to trade him some guns for it. Its a 1980 2wd and kind of big (tall) for my area but its cheap and im sure it would do what little chores I needed it to.

Is it diesel, gas or propane?
