The "Buzzin Dozen" TC-12 Dozer at the 2014 Pageant of Steam

[@arthouston7361]

I saw one working when I was a kid. It was quite a sight to behold. And the sound of those Detroits is awesome.

[@davidyetter5409]

I used to operate machines with twin 6-71 engines... USN Mike 6 boats. No electricity, Hydraulic starters with accumulators to store energy for starting. Used as landing craft to take marines and equipment to the beaches in the early 1970's. USS TULARE LKA 112.

[@jeffharper7579]

Thank you and all the others for your service👍.

[@canvids1]

wow what a machine back in its day and being a old guy I remember them and didn't see many but they were the best back then for sure. the same as I drove White Freightliner tractors with the v 12 detroits and they were so powerful back in those years.

[@jimcarter4929]

Good to finally see a good operator on u tube.

[@tracylemme1375]

It was disassembled into three pieces for transport. After the blade was loaded, the tractor was loaded onto two low beds, connecting pins were pulled and the two halves were loaded. Hearing two Detroits harmonizing under load is best sound ever.

[@BigJfan]

I have owned two 8240 Terex dozers with 8v71 Detroits. Other than the track frames being a weak link,they are a productive comfortable machine to operate. Definitely have a lot of push to them.

[@Tom-xe9iq]

The machine is a Beast!!

[@jakestree1892]

Most distinctive sounding engine to this day

[@andrefalconer6537]

First time I've seen This type twin engine's for a long. long time, Love the sound of those Detroit Engine's This Dozer looks in & sounds in good condition, 😊

[@RickTaylorpopnstart]

Thanks for posting! Definitely bookmarked this one.

GM were miles ahead of the competition before they were made to get rid of Euclid

[@mikeyoungblood1706]

Operated one of these to push TS-24 scrapers while building Disney World in Kissimmee Florida.

[@geraldfrasure9849]

Mike Youngblood I never ran a cable blade , before my time , some of the old hands told me that if you let the blade drop of your lift it would break the cables , and the operator was the one who had to fix it , The operator running that snozer. Is slick !!

[@Muffinrider]

very very cool, surprisingly precise control for a machine of that age

[@lawnfarmer]

That's s good operator to grade that good with a cable dozer.

[@kylebrown8891]

lawnfarmer the guy running the dozer is a fucking arrogant idiot. I watched fin park a grader on a 10• slope pointed towards a whole crowd of people idling at the Father’s Day show in Sharon springs and walked away for 20 plus minutes. I told a couple of younger kids to get off of it because they were climbing all through it. He was probably half drunk in this video

Looks and sounds healthy, good operator too 👌🏻😎

[@nevillebroadbent1601]

I recall as a youngster a TC12 and a D9G have a pushoff blade to blade. TC12 just pushed the D9 backwards. Mind you , the TC12 had a very belly compared to its width so had a habit of getting bogged in soft going. Beautiful machine non the less.

[@nevillebroadbent1601]

Very low belly I meant to say

[@jamesmorton8431]

What a Machine!! 👍 I wonder how much fuel it sucks down in an hour of heavy operation?

[@hotcyr]

Why is there 2 top track support rollers on the right side and only one on the left ??

[@peteprizzi8508]

Why were the track frames a weak link ? Did GM ever fix them before stopping production? I always loved the "EUCLIDS" + The Detroits! It bugs me that Caterpillar dominates the market!!

[@trainman071]

that is one hell of a dozer i love Detroit as well dam good engines

[@mikebythesea45]

Nice restoration Jim

[@Indy6130]

a dream of a dozer, greats from Austria

[@robr5786]

There is a newer model in Wakefield Mi with an enclosed cab,the ground shakes when they run it

[@BerlinghoffRasmussen]

The sound of a 6-71 always reminds me of Greyhound buses for some reason.

[@raygale4198]

There's a very good reason for that, same engine, just running clockwise in the rear cradle.

[@tdshaker]

Two dozers connected into one machine, with one operator. Brilliant idea. But Euclid was not the first to realize this idea. Two Allis Chalmers HD19's were connected into one machine in 1949, on the Garrison Dam project in NDakota. Maybe Euclid stole the idea?

[@donaldbartram6315]

Down here at the Farmhall museum he has a farm tractor like that on display.

[@ClassXIRoads]

Love the 671's my boat has two of them in her.

[@tomchrisfield7348]

I'm impressed by this machine, but also by the dirt. Not a rock it site.

[@robertsnyder5149]

We used to call these the "Pukey Ukes" when I worked the woods because of their color and make. The operator was stone cold deaf when he retired.

[@lewiemcneely9143]

He must've lasted 3 days because he was deaf on the 2nd one!

WHAAAAT?

[@Adamz678]

Just think about it. Stronger than your average caterpillar dozer.

May be but if I had to listen to one on a LONG day it'd be an 8-H.

Comments about him being good at carrying a grade make me chuckle, considering he is working one of the easiest materials on the planet! My families business had a competitor (for a Short time) who ran Detroits, we could hear Just Where their job was, from Miles away🤐

I got to watch it working on Saturday what a beautiful amazing sounding machine!

[@deere7227]

Owned a '65 C6 with a drainage plow for almost 30 years. My left ear took the beating but my right ear still loves the sound. Will this show happen in 2021?

[@earlborchardt4358]

Two 6-110's not two 6-71's. This is the tractor that saved Caterpillar it caused them to wake up to the fact they were not necessarily the best.

[@robertsnyder5149]

We used to call them the "Pukey Uke" mostly from the color.

[@RealJeep]

I still have my Terex watch fob of that dozer. Too bad their main flaw was they tore themselves in half.

[@jamespendergrass4561]

Lemme see, the engine drives the track on its' particular side of the dozer?!?!?!?

[@ShootsStudio]

+James Pendergrass Yes. One engine for each track, each with its own throttle so track speeds can be controlled independently. Also, the forward/reverse control on each track is independent, so they can turn in opposite directions. The whole machine can be split down the middle for transport. It's an amazing machine. Thanks for watching!

[@northwexpress]

Smooth running Detroit 2 sickles. Smooth operator here, too. Note radiators in the back.

[@eltoro6688]

Don't let the nickname "Buzzin' Dozen" fool ya'! The term Buzzin Dozen refers to the Detroit Diesel 12V71 Diesel engine.

[@jaywillow9927]

I think it's cheaper to use a crawler loader. The dozers just pick up the amount of dirt they can push, and pushes it wherever. Lotta diesel used. If you pick the dirt up with a big loader , it's probably cheaper to pick the dirt up and move it vs pushing it.

[@lewiemcneely9143]

Was for me. I could always move more with a loader than a dozer the same size.

[@peterlanum]

Depending on the ground conditions.

rock dawg The series 71 engines Were first released in 1939 I don't know why you think they came along in the 60s

[@Romans--bo7br]

@@billgoodhue5036... actually they first went into limited production in late Sept. 1937... along with a few 3 & 4-71's. the very first running prototype was a 4-71 and I have a B&W 8x10" framed picture of it hanging right over my desk here that was given to me after I returned from VN by my instructor from when I was studying 2 cycle Diesel Engine Design & Theory for four years from 1963 - 1967.... he was one of the original R&D team under Boss Kettering when they developed the first Series 71 engines... wish I had been part of the original R&D team. The picture was taken with Kettering, P. Nicholas (my instructor) and a 3rd fellow whom I've since forgotten the name of... with the 4-71, just moments after it was fired up for the first time. I've been offered "good money" for it... but it is Not for sale. : )

[@kraigcochran9995]

Bet she drinks fuel like it's still 25 cents a gallon LMAO!

[@SummitAggregates]

Actually not really...a 6-71 under full load is burning right at 5 gal/hr x2, 10 gal/hr, which is right at what a current D9 burns...keep in mind, these dozers are roughly 80k lbs without the blade, which makes them up into the 90s with the front attachment - a current D9N/R is about 105k, while A D8N/R is about 84k...very similar to todays machines.

[@SummitAggregates]

A newer version, called a D800, produced from Mid80s, through roughly early 90s when Terex dozers were phased out, due to GM's financial status and market conditions is a really nice comparison to a D9N/R...with a single ripper and semi U blade, weighs about 108k, 12V71T, derated to 370 horse, drinks about 20 gal/hr...granted is much more than the TC12, but, more weight, significantly more pushing power and cooling. You may notice my picture...we have owned ours since 1999. Great machine...hard to find parts for...
