I just read an article about it …“The Tier 4 Bobcat non-DPF solution was achieved by designing an ultra-low particulate combustion (ULPC) engine. The ULPC is accomplished through a specially designed engine combustion chamber that significantly reduces the amounts of particulate matter created during combustion.”

A good piece of info is that bobcat, on there branded Doosan engines uses high pressure common rail. fuel injection. On the early models ~2018, they used Delphi. On the new units, today, they use Bosh. The Delphi system is not as robust as the newer Bosh. All do have problems tho.
Of course, my 2019 had the Delphi system.
If you get or anticipate getting a Bobcat, watch Howididit on you tube, He is awesome!

Its not that they dont have emissions it just that they dont use a DPF to achieve the emissions standard. To my knowledge the tailpipe standard is what has to be met but there is no mandatory rule that a manufacturer has to use certain technologies.
If you truly want to remain emissions free, 25hp and under has the only modern engine options that dont use any emissions related technology and its not even all of them as the most popular 25hp engine is Yanmar and it uses EGR. You're also only going to find excavators under 4 ton (8,960lbs) with a 25hp engine.
Technically speaking and anyone correct me if im wrong, crankcase recirculation, common rail, diesel exhaust fluid, diesel oxidation catalyst, diesel particulate filter, exhaust recirculation, and selective catalyst reduction are all technologies used to increase efficiency and meet emissions standards. Youll see them labeled as CCR, DEF, DOC, DPF, EGR, SCR. They all have drawbacks that many of us dont like.

The modern Yanmar engines, with dpf, are great engines. Have one on my sawmill and in 3 mini x’s. Have yet to have an emissions issue in 5 years of owning.
Yanmar makes great mini x’s, I’d add them to your list if you’re still shopping. Only thing I don’t love about them is no online parts shopping. You’ll need to stick with Deere, bobcat, or kubota for that.

Not all increase efficiency. The fact is, aftertreatments clean up emissions after the internal combustion process. Exhaust recirculation certainly isn't installed to increase efficiencies, but rather to reduce NOX. The high pressure common rail systems do burn cleaner, and create more efficiency.
From what I have herd this is true. In fact, when I was looking for a machine I looked into yanmar. What turned me away was the local dealers that I called would sell them (specifically an 80 class machine), but would not work on them. Also, they did not stock parts. I don't say this to turn anyone away, I say this so you would check prior to purchase. Would hate to see someone stranded without support.

That's a problem with the smaller manufacturers - dealer network and support. Up until 2-3 years ago our Kubota dealer was the homeowner/gentleman farmer type dealer. They built a new building and service bay tripling the size of their facility.
Kubota is a great brand, heck both my 279's have Kubota engines in them but up until now our dealer wasn't set up to support a contractor. Now that we have Cat CTL's and Mini's I am going to stick with them.
These folks that bought all the container chinese mini's at auction better familiarize themselves with fabrication. Or I read over in the scrap metal thread that shred is going for $160 a ton.

hey, this Ex is too big and too expensive: https://lewiston.craigslist.org/hvo/d/orofino-2021-doosan-dx225ll-road-builder/7824027661.html, but take a look at the description:
2021 Doosan dx225ll road builder
5,143 hours
One owner
No liens
Regularly maintained
Emissions deleted
High and wide undercarriage
Wedge style coupler
42” Accurate five tooth bucket w/ progressive link thumb
Runs and works great, No issues or problems of any kind other then a crack in the front window.
Emissions deleted on an excavator. I mean, this is done to diesel trucks all over, and there are companies that do this pretty regular. There may even be kits. Point is - if you get a used/out-of-warranty rig and it's got emissions stuff on it and DPF - where there's a will, there's a way!

hey, there's one of those Takeuchi 135s up here in Seely Lake MT, for 22k. 4.5k hours, was a rental. I have not looked at it.. I think it may be too far, but it offers some hope! That machine is NICE sized, kind of makes a guy think...
EDIT: I just looked up a TB135 on RitchieSpecs, lol, my apologies. I was assuming that the numbers were similar to how John Deere, Cat, etc worked. But nope, a TB135 is just too small at 7831lb.

I see a cat 304c cr cab locally for sale and 2019 50g standard arm deere , e50 bobcats … how do they compare ? The Cat is older like 2010 so should be pre emissions. Would these all be able to lift a 2x2x6 cement block ? I was thinking I would be better of in the 12k lb range machine .

6' ecology blocks are in the 3600-3800 pound range. Pick smaller building units if you can.
a 50 can shift them around in a pinch, but you need a much bigger machine to do production stacking.
Concrete weighs about 150 pounds a cubic foot.

I live on a creek and these concrete blocks got moved during a flood along with the other large bolders /rock . I would like a machine to be able to clean up area and I’m sure flooding will occur again. I would like a machine so I can maintain my property . I see several 2017 e50 bobcats for sale anything to watch with those machines ? I haven’t really been looking at bobcats.

Very happy with my Deere 50d purchased at auction for 18k 3800 hours. Have put 1500 on it .last summer new rubber and rollers.
Never tried to lift cement blocks .Would love to but have not found someone here in the midsouth that sells them.
I have a retainer wall that i built out of 900 railway ties when I was young and stupid. Now they are beginning to rot.

3500lb blocks are way out of the realm of a 5 or 6 ton machine. You can get away with shifting them one corner at a time but forget about picking them up to place them. If this is something you'll be doing routinely you're going to end up with a twisted stick in short time leading to early pin demise and separating welds.
I deal with lots of rocks and my 8 ton machines are pretty inefficient handling anything over about 3,000lbs. You have to be right on top of it to get a good lift and can hardly move it away from the cab before the machine is tipping. Blade down helps but its hard on the machine.
For the money you're looking to spend on a small mini id just find and older 13-16 ton machine for the same price. Machine that size doesn't have to be in good shape to be a homeowner unit unless you're planning thousands of hours use.

Thank you for your perspective. I have moved a few hundred here or there over the years. A 120 can move them but you need to be close. 13-16 tons is better for sure! Especially when the OP is talking about a stream reconstruction. Unless you bench the crap out of everyhing, typically you are reaching out and off-angle and not usually in an ideal situation.
Ok paid a bigger machine to move the big stuff … ended up getting a tb145. I have a question on the tag hook and pin coupler and finding buckets now. Here is a picture of the marking on the coupler qc27 … what do I need to look for when searching for buckets? Also it seems it should be a qc29 according to this chart so I’m confused.

It's the same pin size, which I think is 1.5" dia. The buckets I have for my TB240 work on my TB153FR Wain Roy quick coupler. The buckets for my TB153 are bigger than my TB240. Any bucket brand Wain Roy design with the 1.5" dia will work. When digging in soft soil/dirt, I will sometimes use my TB153FR 12" bucket. I also use the TB153 4' wide clean out bucket on my TB240 for light materials when the machine is on a flat surface. For the TB145 you can go with the QC29.

Ok so the qc29 will be bigger capacity but same width and has the same size pin ? What will the bucket say? Qc29 as one of the lines ?

Not sure what the bucket will say. The PIN SIZE DIA is the most important part on the Wain Roy design. The Q29 2' digging bucket is same with, and taller with more capacity than a Q27 2' digging bucket. The Q29 bucket is also quite a bit heavier. I can move a 2' wide Q27 bucket pretty easily by hand but my 2' wide Q29 bucket is much harder. Q29's will be more expensive. The TB145 can go either way, so look for good deals on used buckets. The more buckets you have the better. The larger buckets may grab larger rocks and logs with a thumb better. Reaching way out down a slope with a clean up bucket, you might as well use a Q27 clean out bucket.
