Made by the Clark Equipment Co. to promote its line of mining construction equipment, this 1960s film shows a specialized Michigan Dozer in operation at an open pit mine and discusses its operation. The tired Michigan is shown working with swing shovels, cleaning up ore piles and loading trucks. Tips are given about how to operate the machine properly.
Michigan wheel dozers were well accepted by the earthmoving industry and found use in all manner of operations. Initially based on the chassis of one of Michigan’s existing line of wheel loaders, the model 180 was nevertheless regarded as a success and development of other machines followed. It became apparent to Michigan, however, that some modifications were required to fully realize the potential of its wheel dozer, resulting in the development of a dedicated wheel dozer chassis, rather than adaptation of an existing loader chassis. This was very much a step in the right direction, and the models 180-II, 280 and 380 wheel dozers were introduced the following year. The chief drawback of the design was the wide area needed to maneuver around as the machines all had rear-wheel steering as did almost all of the wheel loaders and dozers of the time. LeTourneau’s machines were superior in this respect as their steering acted more like a skid-steer loader of today allowing them to execute a 180 degree turn in practically their own length. This though, while convenient, was quite hard on tires.
A solution was close at hand, however, with the development of articulated steering. First pioneered on Mixermobile’s ‘Scoopmobile’ wheel loaders, the concept soon caught on and by the mid 1960s, most major manufacturers, including Michigan, were offering articulated steer machines. Michigan applied this new technology to all its wheel dozers except the 180 which by then was up to its 180-III version. Michigan was also at the leading edge when it came to large wheel dozers. Clark's biggest machine, the 52-ton model 480, was introduced in 1958 and featured a 14-foot blade and 20 miles per hour top speed. An articulated version of this machine first appeared in 1965 and found immediate acceptance in surface mines where its speed, blade capacity and agility made it the ideal tool to clean up around face shovels in the pit. It remained in production until Clark-Michigan withdrew from the heavy equipment business.

Please more old construction & truck videos! As a student of history & engineering, I can't get enough of your page.
During WWII, my father worked for Clark. Because he had wartime, an essential job, and a family, he was exempted from the draft. Also, over 40.
One thing to go to a museum and see some of these incredible machines but to see them being worked in these videos puts everything in perspective. Thanks for posting.
good to see machines that i helped build at Clark Equipment Australia in action as i only saw the being built in the factory and leaving
Nice to see the old machines at work. I've seen some of the American construction machines in the 1970's in the Arabian Gulf oil industry and other works.....Caterpillar, Oshkosh. Terex, White, Reo, etc. The Saudi Arabian oil industry has had most of its hardware from the US.
I really enjoyed watching this, as I have one of those Michigan wheel dozers. Mine is a 280 model, with a Detroit 8V71. There are a couple of short videos of it on here. Just search for "cleaning up a skid road with my wheel dozer" if you want to see it.
The dangling cigarette is absolutely necessary for proper operation
For those wondering this was filmed on Minnesota's Iron Range at several different properties in the early 60's. Michigan must have been running demonstrators around to the different mines.
super film

Geez that thing looks hard on tires!!!
I once worked for Clark Equipment in Australia. They liked us watching lots of training films similar to this. The Safety ones were the best showing fake gory accidents. Have you got any of those? They were worth watching better than old michigans. Cummins 555 engines were common and some used to of them. One for driving and other for lifting. :-o
Were you at Asquith?
😎 video on construction equipment!
If Tires were the answer, we wouldn't have so many tracked machines today! Time bears out all things.
Oh it's like a precursor to the Front End loader
nice
I have a friend who worked at Clark Buchanan plant up until it closed. Clark loaders and other equipment was everywhere around here in the early 60s. I live in northern in sw michigan as a kid. 👍
I worked at Pipestone Engineering in the early 80s . I was on Loaders but was seated 2 drawing boards in back of the 380 dozer guys.
The end was already in sight but the shareholders were blind.
Hmmmmm I would draw that line someplace just south of the South Haven to Battle Creek line.
Anyone know the type of truck that was with the big dump bed and low sides? I'd like to see more of that type of dumper.
I wonder who the rascals were that stepped back and looked at this design and said. Yep that’s it !! Looks exactly like a kindergarten kid drew it. lol
Neat
When did they go to articulation?
رائع ممتاز جدا
0:33 is there one of those truck and trailers preserved anywhere?
Chisholm MN. Minnesota Museum of Mininng. There is also a newer one in a city park in Babbitt MN.
Ahh I can almost smell it

Transmission was junk.
