I can’t speak for everyone. It those that operate the new machines like the manufacturer calls for have few if any issues. Those that do 2 minute tasks and idle it a lot do. I use my tractor every day and it has never had a problem with the dpf. I don’t idle it unless I need to get off for a few seconds and get back on I am approaching 700 hours on 5 burns

Again, quite similar to modern diesel pickups.

Personally I hate the DEF fluid the DPF filters but they are probably here to stay

Sure are. Next lawnmower you buy will have a Cat in the muffler too. Chainsaws are already there I might add. Stihl is circumventing it with their E-Tronic system but eventually they will also succumb.

If you purchase an Echo homeowner grade (clamshell) saw, it will have a Cat in the muffler, only the Pro grade arborists saws don't have them and you have to replace the Cat muffler to eliminate it as the Cat is welded into the inside of the muffler. Least Echo still sells a non Cat muffler for a while at least.

gee, I'm over 6000 hours on one and 4000 hours on the other and NO burns...lol

One reason I am heavily considering the Kioti CK20SE series with the cab is because all three models weigh the same, and have nearly all the same dimensions. 3,397 lbs. And they are not so wide that any one of them would give me headaches trying to get between the trees on my property. 54.53 inches.

So I need to find out prices to see how much the higher horsepower models will cost and figure if one of those would be worthwhile for the modest HP gains even with this emission stuff involved.

The difference in 25 hp and 35 hp is significant. The 25 hp model is going to be critically underpowered. They wouldn’t even offer that option if it wasn’t for the emission standards.

I can tell you from experience with my L2501 HST, going from 25 HP stock, to 44.1 HP with the Turbo Kit, was a significant improvement in operating performance. Luckily, no regen or DPF for me.

@Rich_Z if you've not checked Mike's thread on turbocharging his L2501, you ought to. The ability to modify the tractor to produce more power, after the warranty expires, does exist. Now that's not necessarily something that appeals to you, but it may be something to consider.

I certainly keep the possibility in the back of my mind.

DPF equipped tractors produce only ~ 1% of the cancer and smog producing diesel particulates which are produces by ~ 25-horsepower diesel tractors without DPFs.

Turbocharging an L2501 so it produces 200 times as much pollution as a 33-39 horsepower, DPF equipped Kubota tractor should be a crime.

If you need > 25-horsepower buy a DPF equipped, legal machine.

How’s that? Did you turbo a L2501 then do emissions testing? A properly tuned turbocharged diesel burns pretty clean.
