'Question' From MPJ

Posted by Deas Plant. on May 04, 2003 at 02:52:39 from (202.138.18.28):

Hi, MPJ.
Brian was referring to, I think, 'Big Roy', a 600 horsepower 'one-off' built by Versatile and now in a museum in Manitoba. See the link below for the specs.

Somewhat bigger than Big Roy was the one-off Big Bud 16V 747 at 900 horsepower. This tractor, according to the website below, is still on display at the factory at Havre, Montana, after being restored. There were a couple of other Big Buds built at 740 horsepower as well as a heap of other smaller ones. Type this URL into your browser address bar for photos and info.

(If you leave the BB747.htm off, you will go to the Big Bud home page from where you can still access the 747 page.)

A farmer in Canada either built or had built for him a similar 700 hp tractor some years ago. I have a photo that I can post if anybody is interested --- and if I can find it.

I also have a photo of a 650 hp Cat. diesel-powered tractor bearing the name Rome that had THREE axles, all with dual wheels. Again, I will post it if anybody is interested.

If you want to include ALL tractors that use tractive power to accomplish their tasks, you then move into the realm of earthmoving and construction machines. The biggest machine I know of in this category is one of unknown origin that I suspect may have been built by R.G. LeTourneau. I have posted a photo taken from a newspaper in the Tractor Photos section under 1957 Wottizzit. It is currently between #944 and #959 but it won't stay at those numbers for long.

Or you can e-mail for a copy of the photo.

Biggest grader is next on the list at 200 tons. Built by Umberto Acco of Italy for a contract he had in North Africa in 1983, it has a 1,000 hp diesel driving the rear tandems and a 700 hp diesel driving the front wheels, a total of 1,700 hp. All wheels are duals and it has a 33 foot blade. I have photos of this machine if anybody is interested. It is still in storage in Italy.

Biggest 'dozer is a toss-up between another Acco machine, a 183 ton twin-engined crawler 'dozer of 1,350 hp, also built for the above-mentioned North Africa contract, or the Western Contracting
Western 2000 built in 1963 for the Milford Dam project in Kansas at 170 tons and 1,600 hp from four 400 hp electric wheel motors powered by a 1,450 hp diesel generator. I also have photos of both of these machines if anybody is interested. The photos of the Western 2000 that I have are courtesy of another regular visitor to YT. Thank you, Tim.

The Acco 'dozer is still in storage in Italy. I suspect that the Western 2000 is now history and has been scrapped. I'm told it worked from 1963 to 1981.

Also, some months ago, another regular visitor to YT, T-bone, said in a post on the 'Crawlers'
forum that his son had recently had a play on a 'small 'dozer' that, if my memory serves me rightly, was around 4,700 hp. This would put ALL of the above in the shade.

Any other contenders?

Hope this helps.

You have a wonderful day. Best wishes. Deas Plant.
