My great-grandfather left home at 14, and no-one today knows how he managed this, but somehow learned how to run an RD6. That same year he hitched into the rough project of building the Fort Peck Dam in Montanna, living in a tin and plywood shed at night and driving one of these every day. When I was little - maybe 6-8 years old - he stopped his truck one day to show me a Caterpillar RD6 hauling big lumber like your opening shot in a forest off of Highway 101 on the Oregon Coast near where he lived. He told me about how much he loved driving it when he was a young man, and to this day if I have a chance to stop and listen to a big old Caterpillar tractor, and no-one is in the car with me, I will stop and listen to that amazing sound and my amazing grandfather is there with me. Thank you for making this video on my birthday; I'm about the same age he was when that happened.

I had the chance to run a D8 about 20 years ago that if memory serves me right was built in 1947. After running a newer version D6 from the early 90's it was really something to fill the blade of that D8 on a long push and feel it put it's head down and work. That D6 was nice with all the newer technology but it was a screamer and burned more fuel for the same amount of work at the end of the day as that D8. My John Deere two-cylinders from the same era share the same concept of torque and low RPM to get work done. My D has a bore and stroke of 6.175 X 7 (501 cubes) at 900 RPM, 29 draw bar, 42 belt hp. My 820 diesel is 6.125 X 8 (470 cubes) at 1125 RPM, 67 draw bar, 72 belt hp. Those old timer engineers understood big bore and torque and put it to good use, probably one of the biggest reasons this old equipment has lasted as long as it has!

But I remember dragging a small chisel plow to the top of the field, on a hill, lugging that thing down so much you could almost count between the combustion strokes.., making a turn was a very physical operation..pull in the steering clutch, stand on the brake on that side, bring it around, reduce power and shift it a gear up for the ride down, barely slipping the main clutch, trying not to grind the non synchro gears, throttle her back up in one orchestrated fell swoop of the controls.. and that tractor was made in 1938(?), forty some years old at the time. Along time ago..brings a tear to my eye. I understand now why my grandfather would give me the eye when I was being hard on the equipment. Enjoyed seeing this, thank you!

About 30 years ago a guy I used to know bought this beater bulldozer that I believe had a 2-stroke diesel engine. The dozer was all worn out, but wow did that engine still sound great! I loved the sound of it.

In 1970 I was working for a wheat farmer that had one. Serial number 346, a 1938 if I remember right. He had run over some posts and broken the fuel filter housing. The Cat dealer in Lewiston Idaho was able to get one in about a week (it was in Georgia). Cat, at least back then, supported their old equipment. Unlike some others I can think of.

they still are one of the best manufactures when it comes to parts support for old equipment, we have a few 70s era crawler loaders and have no issue getting parts. cant say that for most other manufactures out there.

Federal law says that a manufacturer has to support for 10 years after end of production , most of them don't do a day more . I worked on some 6 110s in 1970 (they stopped production in 58) , you could get after market rebuild kits but hard parts like the fuel rails were na, and the 110s would break them do to vibration from the length between cylinders (the 71s didn't have the problem . Cat has always done a good job of supporting their equipment . They are usually better at thinking of the mechanic that has to work on it .

one HP is the ability to move 33000lbs one FT in one minute. Worked out by James Watt of steam engine fame, by how much coal could be pulled from the mine, also the unit of energy was named after him, Watt.

Horsepower is how fast you hit the wall and torque is how far you take the wall with you. Fantastic video !

You're comparing velocity and momentum to horsepower and torque. Not really the same thing.

Actually, HORSEPOWER Is defined as the ability to do a certain amount of work in a given amount of time and TORQUE is defined by the twisting force of a shaft. One horsepower is 33,000 Ft.Lbs. per minute. It's the same as lifting 3,300 lbs 10 feet in one minute. or 550 ft. Lbs. per Second or 1,980,000 Ft. Lbs. per hour. JAMES WATT Came up the unit of horsepower while using a large draft (draught) horse to measure the horsepower of his steam engines. Power is the rate at which the work is done therefore the formula is POWER = Foot Pounds divided by Minutes. Ok: Horsepower - Speed vs Torque-Strength.
