Actually, what they do is when the DOT does a roadside inspection in a rest area or weigh station, they check the opacity of the exhaust flow. Pretty simple really and if you don't pass, the fun begins. Of course that only applies to Tier 4 final trucks.

They have this neat little instrument that measures it. What they do is have the driver throttle the engine from idle to governed speed and they check for visible particulates.

If the engine fails, you are in deep do do.

I don't see that ever happening to to tractors though. Highly unlikely to have a 'Barney Fife' driving down the road with a meter checking tractors.

The diesel truck modification I wish the DOT would enforce more diligently is operating diesel PU with no mufflers. IMHO that has to get 1st place trophy for the most annoying sound. Don't get me wrong in my younger days I had vehicles with loud exhaust but those 6 cyl diesels have a very annoying tone. I wonder if operating with no muffler actually increases fuel mileage??

A turbocharger is actually considered a muffling device. You want to hear loud, a diesel with no turbo is 10 times louder than a gas engine. In facc, Vo-Mack marks their turbochargers as 'muffling devices'..

While this can be useful to some, I more wish they would start working on DPF deletes for these small tractors.
That's why I limit my new buying to 26 h.p. and anything above that I buy old stuff.
I totally get the wish to remove the DPF stuff.

Unfortunately my experience with guys chipping their trucks are also the ones who remove their mufflers and add jake brakes to their lifted 1 ton dually so you can hear them 10 miles away at 2am with maximum performance for hauling nothing but air 99.9% of the time. Or see them billow out giant clouds of black smoke making jack rabbit starts at stoplights with their fake testicals dangling from the back of their rusty trailer hitches.

Agreed, Flip.

I recall a local Autocar tractor operated by a local oil distributor in the late 1960s-early 1970s with an unmuffled stack and no turbocharger. It was certainly the loudest road tractor that I have heard.

The driver knew it, and liked to tweak the populace.

An interesting fact on some M7 models you can increase the HP by up to 20 by engaging the PTO! Why would they do that?

I do not remember all the criteria that have to be met for the "power surge" to occur, but it gives you that little boost when you are on the edge.
New Holland CR combines have done it for years when you are moving, have the separator engaged and engage the unloading auger.

Either wore ear plugs or was stone deaf. Diesels, by the very nature, being compression igmited are really loud with no turbo or muffler. Gee, Autocar, probably a 270 Cummins. or a 6-71 Detroit.

What angers me is back in the day before emission motors, all my big rigs had straight pipes. I hauled logs, wood chips and dump trailers up in northern Ontario.
I didn't run around in the city. I was on desolate highway with nothing but trees and moose.
Yet the MTO would harass me about no mufflers.

BUT every wanna-be hell's angel yuppie douche in his crisp shiny new leathers can put open pipes on his harley and race around town holding it wide open all hours of the night.
And now I get to listen to snowmobiles on the lake in front of my house with open race pipes all night.

But they seem to ignore those guys.

Oh well, I always knew how to get those straight pipe fines tore up.

Which reminds me, I'm still looking for an Oliver Super 99 or the Massey version so I can listen to a straight piped 3-53 Detroit running around my property.

Dad had a Cochshutt 570 super with a strait pipe. Nicest thing I ever heard! That 70HP 340 cubic inch Hercules Just purred under load! We had a Richardson front snowblower on it with halftracks, you could hear it coming down the road a mile away! We used it to open roads in Ontario when the road graders got beat.

It was a 4 stroke, not (my favorite) a Detroit.

I believe that the Super 99 (and MF version) used 3-71 Detroits, though Oliver did use 4-53s in some models.

I'm biased because my Father was a field engineer for GMC Truck and Coach for 30 years before retiring in 1969, but I love the sound of a Detroit.

The engine was a Detroit 371 in Oliver Super 99, Oliver Super990 & Massey Ferguson 98. The MF 98 was produced by Oliver, dressed in Massey sheet metal & painted red.

They sound awesome wound up & under load.

Massey 95, Super 95, & 97 were produced by Minneapolis Moline for MF where they were dressed in Massey sheet metal and painted red. I believe the engine was 425 CID MM engine. 4.25" x 5" bore and stroke. With 3 2 cylinder blocks and heads lined up in a row it made for a long engine.

And a long tractor with a big turning radius! Perfectly suited for prairie farms though!

The loooong wheelbase with the heavy engine also took away a lot of the bounce on rough ground, the ride was like sitting on the couch.
