The reduced particulate output from <19 kW engines in 2018 is all or mostly due to Ultra Low Sulphur fuel.

Hey jeffy, did you read post 35 ???? Welcome to the thread !!! You forgot to REPEAT the direct injection portion of my post !!! And tier 2 was met with both low and ultra low sulfur content. When copying a post, do so in it's entirety to avoid misinformation.

Yes, it absolutely meets tier 4 final standards. But those standards require a different level of emissions for tractors over 25 horsepower. So yes, it's compliant with the standards, and no, it doesn't have the same emissions controls as the larger tractors (the 3301 for example). This can be seen at this link Emission Standards: USA: Nonroad Diesel Engines, in table 2 a bit over half way down the page. Tractors 11-25 HP can emit 6.6 grams of CO per kWh, where tractors 25-50 HP can emit 5.5. For nitrogen oxide, 11-25HP can emit 7.5 g/kWh, 25-50HP only 4.7g/kWh. Particulates look to be the biggest difference, 11-25HP can have .3g/kWh, 25-50HP must be 0.03 g/kWh, so ten times less.

Bottom line is that a tractor in the 11-25HP class generally doesn't need a DPF to meet Tier 4, and a tractor in the 25+class generally does.

So, you need to either buy a tractor 25HP or less, or buy a tractor 25-50HP with a build date before 2013-ish.

In a perfect world you'd be able to buy an L2501 and then do some aftermarket tuning to produce more power. Presumably that's illegal or discouraged though.

Splitting hairs here, folks.

It's all federale nonsense.

It is the 'Grand L' HST/PLUS transmission that will most impress you.

That's probably why I have a L4060hstc instead of a Korean tractor. Every HST I've ever driven has a 3 speed (occasionally 2) that shifts like a transmission from the 40s. Have to be at a stop, then fiddle with things to get the gears to mesh. HST+ means you dont often need to shift out of the middle range. HST+ is just nice.

Fallon,
I have not driven a Korean made tractor. Are you saying they can not be shifted easily between ranges? Which brands/models did you test?

Never experienced the Plus or really had a clue to benefits... unless my Deere 110 would be similar?

Is the plus heavily dependent on electronics?

I had one sensor fail on the Deere and the Dealer started quoting transmission rebuild because the Tractor basically would not move.

I know of no CUTS, SCUTS, or even utility tractors that have synchronized range shifting. Consequently, one must stop to shift ranges.

Aside from other features, HST+ adds a hydraulic HI/Low that can be shifted on the fly by the operator (even automatically by the controller). Functionally, it is much like a power shift but no gears are changed. Rather, the angle of the swash plate is hydraulically changed, effectively changing the ratio.

I have 3 tractors and have operated many more. All the hydrostatics make you stop to change ranges. Some tractors are easy to change ranges, some take a Little wiggling. As posted, the Kubota Grand let you go between a high and a low in each range. I have used it M range bus hogging, and in H range when driving on the road.

I’d be curious to know if you have to stop to switch between ranges on the new Yanmar iHMT transmission. Anyone know? The Kubota HST+ and the Yanmar iHMT seem to be the bees knees of transmissions in the modern CUT market.

Yup, couple nice things on HST+. There's also a mode to up the rpms for loader work without changing ground speed. Messicks has a good video covering it:
