dozer question

[Mac Leod]

hello, I was waching an older movie (late 50s or early 60s) and there was a bulldozer. the Bulldozer was split doen the middel so that when it hit a bump on one side it would kinda pivot. what is it???..Doubt I am making too much sense but it is the best I can do

Are you referring to a TRACKED dozer or a wheeled dozer? There are MANY articulated wheel dozers. I don't see how a tracked machine could be articulated----the tracks would run off......................

Well.... Some of the early Holts and Caterpillars had track frames that would hinge in the middle to adjust to the ground as it went along. This was soon abandonded in favor of ridgid track frames probably due to wear or alignment issues. Seems to me the 10 Ton Holt was that way which was the forrunner to Caterpillar... Caterpillar was the Result of a Merger between Holt and Best forming Caterpillar Tractor Co. So there were Best and Holt before 1925 and Caterpillar after... Even on Later Cats there was an Equaliser in front so one track could go over an obsticle without affecting the other...

it was a tracked dozer. newer at the time of the movie, 60's or so and the tractor its self was splt in to two sections. right down the middel

That sounds like a "Movie Prop"

[Craig A]

Yeah----something VERY fishy about THAT. BIG difference between individual oscillating tracks and articulated.

[Mac Leod]

I do not think it was a movie prop...the movie was about building a church or something along those lines... the tractor had no real part in the movie.

I believe it was Allis Chalmers that built a double barrel. Two units were joined together on a pivot at the rear drive, each engine drove a single track. If memory serves me correctly, it pushed a 14 ft blade. Two 6 71 gmc engines. Units such as this were used in the dam building along the Columbia river where large amount of dirt and rock needed to be handled rapidly. The era of large machines such as D9s and larger had not happened as yet. Cat hooked two D8s together tandem withe the rear unit controlled from the front hydraulicly. These also pushed a wide blade. It has been about 50 years since these were used and the same amount of time since I saw them.
Any way is it possible that a double barrel is what you saw? Carl

[Mac Leod]

Carl...That sounds about right...it was huge. well over the height of a man or two (short ones)


Thank you, I can finaly get a good nights rest now.

I think Euclid made something like that? D9 goes back to late 40's I think they still use 2 D8's hooked together.Back in the 80's I seen a couple of them cutting a new road in Idaho.BobRR

I think this is the dozer you saw. It is a Euclid/Terex TC12.

[Mac Leod]

Wayne, THATS IT...sorry for not posting sooner...I guess when it got moved to tractor talk I lost track of it---I did not start watching this fourm until recently, I was doing a search for somthing else when I found that post...did you take the picture?, it is dead on what was in the movie. WOW, what a machine, cant wait till I get my own!!!

Dear Mac The dozer is definitely a Euclid or Terex[later version] model TC12. It was powered by 2 6-71 GM diesels with each engine running a seperate track. There was no connection between them and they ocelated up and down seperately. Some of them used 24 and 30 foot wide blades and used widely in coal mine reclamation projects. There are quite a few still in existance around the country but hard to find one for sale. We have one operating at the Zagray Farm Museum here in Colchester, CT and we run it at the 3 shows we hold each year. There was a great story about recovering one from the bottom of a mine in New Zealand that appeared in "Antique Power Magazine a few years ago. It had been under water for many years and after recovery it was up and running after draining and replacing all the fluids in a very short time. Good luck in your quest to find one. The Yankee

what movie was this in? my grandpa used to work on these machines he would probably enjoy watchin it. we used to have a C-6 which was half of a tc-12 and it is located close by to my house where a farmer uses it and might have to buy it back one of these days

I think there is one setting out front of Mac Faddens Tractors in Sharon Springs NY.
