moviegoers in 1931 got to see a humorous look at “The Great Tractor Race” in which the Cat Ten, Twenty, Thirty and Sixty traversed rugged, hilly terrain and crashed through buildings (Skip the first 4 minutes)

this 1930 Caterpillar Thirty tractor is the most original operating Thirty known to exist

Bought from someone in Minnesota, this rare, all-original Thirty that had been well maintained over its 95 years – and is still in top running condition.

The tractor had been owned by a farming family in California, they grew up with it and did  an amazing job taking care of that machine its entire life

“He still had all the original things on it that were bought at the factory,” Walker says.

That includes components very difficult to find today, like the fan guard on the right side of the engine, the radiator cap, fuel cap. He even still had the brass key for the magneto.

People abandoned their cars, blocking a road that the fire dept MUST USE so, they brought in a D8 dozer to clear those cars out of the way (watch at 2X speed)

 

For context, on WHY they abandonded their cars in the damn way, blocking the road, not even pulling off to the side of the road, skip the first minute of this next video

the Allis Chalmers HD 14 tractor crawler came from the factory with railroad track welded into the sides of the tracks machinery (thank you JBFRMCA!)

 

and one ended up in the river at the bottom of a Happy Valley, south of Jenkinson Lake, Ca, and was never pulled out. 

Butte creek, Happy Valley Rd

abandoned 1953 D7 is the a "will it start project for these guys. It was parked, mostly in the barn, after the clutch had a "Stuck" problem about 20 years ago

 

saving an abandoned Cat D4 and getting the track back on

Assembly of a Cat D11... it's amazing how much the parts weigh... 5 tons per track, 12 tons per track rail

the IDF has uparmored Cat D9 dozers for making 15' wide roads through the rubble. That oughta get the job done. They even have one that works by remote control

If you need a big OLD Cat, grader, etc - even for yard art at the farm driveway entrance, there is a good size collection for auction... lots of old iron eye candy, and a couple of mills and big lathes

1945 D7 still putting in a hard days work, with only 1/3rd the power a modern D7 has. 80 Hp vs 240 Hp

someone wants a road through here real bad

demonstration of how powerful a pair of C8 caterpillar dozers are (as always, skip the first minute)

I prefer to watch bulldozers that are D6 or bigger, and tackling rough forests to break through new roads, and finally found a you tube page from Turkey that features exactly that

this guy has 4 of these Fiat Allis dozers, powered by Cummings 1150s, with 22 ft blades, using 22 gallons an hour, weighs 96,000 pounds. 2 guys working side by side move a 44 ft wide path. These came from coal mines

a WW2 Clark CA-1 crawler bulldozer made to be delivered by C47 or glider, for the army or Sea Bees to clear landing strips from jungles, was found in New Zealand and restored, and a the right scraper for it to tow was imported and restored

how do the bearings in the bogies not seize from the heat?

D11s at work on an Australian farm. A D9 would have cost them 450k, the D11 was 250k, and the 2nd D11 was bought for parts, but turned out to be a 20k fix. So then they had two! The farm needed a dozer for flood repairs

Drones are so damn nice for video work like this

one of a kind prototype 1956 crawler tractor, basically a production 445 tractor that had the rear end housing removed and replaced with a prototype back end that had final drives in place of the axle tubes.

 

thank you KittyCatMarty! 

Hell of a restored tractor collection up for sale, with full size, and riding lawnmowers, and pedal tractors too

 

that is just pretty.... and a track tractor (I can't remember the official term)

I've never heard of a Pennsylvania Panzer until now, 

Didn't know Minneapolis Moline made riding mowers

and didn't know I wanted a Snapping Turtle self propelled mower until now! 

I had 10 minutes for afternoon work break, and this was how I used it.

looks like it was meant for a seriously hazardous work zone

anyone know what this was built for? 

Maybe meant for working in the jungle? underground mining?
