Apple is worth over 2 Trillion dollars.
Exxon is worth 240 Billion....


Exxon occupied the most valuable spot in the Dow for several years. GE occupied the most valuable position in the Dow under Jack Welch for longer than Exxon.

The world economy is dynamic. Change occurs.

I speculate we will see battery powered sub-compact tractors for sale by 2026.

Exxon was founded in Cleveland as Standard Oil by some guy name Rockefeller.

Generous Electric, I wasn't aware that they were that big for that long. I would have thought generic motors displaced them for most years. Maybe pre WWII? That probably would have been Ford, no? Maybe before Ford. Whatev. But GE was big, we all know that.

I suppose that all monopolies try to steer the world in the direction that best suits them. I think it's why we tried to outlaw them some years ago.

In transportation, generic motors did it in the 50's and 60's and 70's and 80's. Before them, the Vanderbilts tried it with Railroads for at least a half century.

Now we have Big Tech trying to steer transportation through politics and skullduggery. Not that their progenitors were any better. Certainly not generic motors who suckled at the government teat for decades and steered legislation to benefit their preferred means of travel.

Had I been aware back then, I wouldn't have not liked what they did any more than I like what Big Tech is doing. I should have thought we've outgrown that kind of nonsense.

But, it seems, we have not.

The harm done to us by a self-serving Railroad cabal and the very self-serving auto industry led by gm will seem like child's play when Big Tech gets done with us. They're dangerous. Big Tech wants to control every single aspect of our lives and they've struck a Devil's Deal with Big Government. (What's it called again when Big Business and Big Goobermint form a coalition??)

The people that came before them were just greedy. These people are far more than that.

Big Business can be controlled. Not easily, but it can be controlled much easier and with much less effort than Big Government.

Big Government is simply evil. Virtually every bad thing that has happened in this world for the last 150 years was caused by Big Government. People don't start Wars, governments do. People just die in them.

Not only do I not trust Big Government, our Country was founded on a distrust of Government. ALL Government. The Bill of Rights does nothing other than limit the power of Big Government. The rest of the Constitution grants rights to The People.

So any time Big Government gets in bed with Big Business, I get nervous. And that's what I see going on these days.

I don't see this as partisan. I don't see it as political

Can I run a regeneration cycle every 10 hours? Would that be bad?

With most Tier IV tractors you cannot initiate regeneration until the DPF sensors sense the DPF is loaded.

A dealer with the proper computer software can trigger regeneration sooner but a tractor owner cannot.

Each regeneration detracts from the DPF service life. If regenerated every 10 hours, rather than normal ~~ 60 hours, DPF life MIGHT be 500 engine hours, rather than often quoted "normal" ~~ 3,000 engine hours.


I eventually plan on leaving the tractor at a remote property that is not accessible from November-May.

Non use for an extended period probably will make your tractor problem prone. I have had very few problems with my 2013 purchased new Kubota. As a retiree I have the tractor out for at least an hour or two, two to five times per week. I live in Florida where the weather is moderate. Only two or three mild freezes per year, few days above 95 degrees.

Most here consider stale fuel a significant factor leading to engine problems.

Also consider theft. Tractors do not have nationally databased VINS accessible to law enforcement like road vehicles. If your tractor is stolen, most often it is gone for good.

Is the DPF that much of a detriment? Would you pass on a used tractor because of it?

Stricter Tier IV off-road diesel engine emission reduction standards phased in on dealer tractor inventory 2009-2012, impacting tractor prices.

Tier IV emission standards require tractor manufacturers to add or revise pollution reduction technology on new tractors generating over 19 kW power = 25.4794 horsepower.

DPF is used by the majority of tractor manufactures for more powerful tractors, but not all.

It is fact that Tier IV technology complicates the engine package and a significant cost factor.

Diesel Particulate Filter (DPF) captures exhaust particulates (soot) in a ceramic matrix. When tractor engine runs sufficiently hot, accumulated particulates burn off periodically without operator intervention. If engine is not run continuously hot long enough to burn off particulates, diesel soot accumulates in the matrix. Once heavy soot accumulates in DPF the tractor forces soot clearance with the tractor parked and throttle open to about 2,200 rpm for about sixteen minutes, which makes the DPF REALLY HOT to burn off all accumulated soot. Burning off accumulated soot, either during operation or parked is called REGENERATION.

Regeneration is an infrequent DPF event with my Kubota three cylinder, 37-horsepower engine. Generally once every sixty engine hours. (Very consistent in Florida due to warm weather.)

The pollutants emitted by a Tier IV technology tractor are about 1% of the pollutants emitted by a pre-Tier IV tractor.

L2501 is one of Kubota's highest unit volume models. It is also a legally dirty bugger.
Kubota's L3301 is the same tractor with eight additi onal horsepower and requisite Tier IV paraphernalia. Your money, your choice.

The claim that an L2501 and L3301 are the same tractor with different hp levels and engine management systems is false.
You really need to check on some of the stuff you post here. Many folks have the mistaken impression you don't post falsehoods.
An L2501 meets the same emission standards as any machine in its HP class. The insinuation that it doesn't is misleading at the very least.

But other than engine hp and emission system they are essentially the same tractor, right?

They have very similar dimensions. Might even be the same frame. I do not know.

However:
They have different engines of different sizes.
One has a gear transmission with a hydro option, the other has synchronized shuttle transmission with a hydro option.
The L3301 can go faster in forward and reverse.
The L3301 is an inch longer.
The L3301 weighs more.
