I have been running one for Ames const. for two seasons now and love it. More power to the ground than you can imagine! 4100 hours on it now and no trouble with electric drive. Only issues have been a lot of emission issues. Regen/Def issues. The turning while pushing dirt is also very impressive. Nice machine
@@blessed7fold have had I think four def pumps put in. Most recently had not used any def for over a week but no codes then it went into limp mode. Replaced the def injector and did some software updates and is fine now. Another issue I experienced is the cable that goes to the blade sensor for the gps. Dirt chunks come over the top of the blade and land on the cable and break it. Of course parts are hard to come by during these covid times and it's 1000 dollars a pop. Two cables last year and 4 this year.
I am not currently running the d-6xe electric. It got sent to a job in California cause that project needed to fulfill certain emissions standards. Just running a mechanical d-6 now.
Why did they drop the electric drive in the new D7 and also go back to the Hi Drive and a conventional transmission, if electric drive was so good why go back .

So has anyone at Caterpillar performed a feasibility study comparing operation of one large tractor such as a D8 or D9 to two smaller tractors connected in tandem such as two D6 tractors with one blade and operator? The electronic controls on such a machine like this would make control of two machines from one operator station being a plug and play with a drawbar connection being the only physical linkage. It could be a way to get around special transportation permitting.
I’m confused on what function the electric drive gives if there’s still a diesel engine? Is it just less load on the engine itself because other components use the EM?
This transmission is not new just more modern application of an electric transmission. Thomas Tilling introduced the first petrol-electric bus in London in 1908 and a small batch was produced in 1911. They were produced by Tilling in Peckham with electrical equipment by W. A. Stevens of Maidstone. The buses ran on electric motors powered by a petrol generator. This example is from the second generation of these buses, which were introduced in 1921. The Museum only holds the engine, generator and chassis. The body was lost when the bus was converted into a generator in 1938.
Hi James! The single electric motor powers both final drives. This gives you the same turning power and differential steering capability as with a traditional transmission, but with constant push and greater efficiency.
@Kathleen Shaw it's not that, has to do with size of engine they run, limits how big of genset you can run. Smaller the machine, smaller engine, smaller generator. Smaller drive motor. I'm pretty confident cat engineers work with kirchhoffs laws designing this to create max performance.
@@rogermeeker3789 how can it be more simple? D3 is the smallest d11 is biggest, how can it be more simple lol? Even their serial numbers are simple compared to others.
I wouldn't waste my money their engines are throw aways.Challenge cat to make D6 that can run to 7000 hrs without eating a set of injectors or losing a NRS cooler resulting in bent rods.Wake up Cat your bread and butter machines are losers.
Customer: your dozer is way over engineered. Cat engineer: let's add a big battery, electric drive motor, but keep the diesel engine as an onboard generator.

Please explain the emissions issues you have been experiencing.

@@blessed7fold All the new machines have serious emissions issues.
Mike. Are you still operating an electric drive dozer?

Your right locomotives have been build this way for years because of the efficiency and unlimited control points. I think it is going to fly.
Ships with azipods also use the diesel/electric power system.
Topsy from Edison motors is the first semi to use diesel to electric idea plan.
Love it. Much better than a hydraulic drivetrain. Especially with these forces.
So ...basically like a diesel locomotive?
We love the way CAT Equipments are built. We support CAT!
What are the advantages and disadvantages of an electric drive over a hydraulic drive?
immediate power availability at final drive and more torque with less engine output
RG Letourneau would be proud!

Solid state batteries will be a big help.
How reliable would the electric drives be under constant load; compared to the old direct drives?

How much will this cost to fix once it starts to have problems
Why are none of these videos on channel 1? Why not add these plus additional technical videos on channel 1?

Cant wait to see one on a job, looks like a cross between a d6t and d7e, two awesome machines
we have one of 11 of that model at zeppelin
So how does it steer with only one electric drive motor? Braking one track would be inefficient and that approach wouldn't allow counter rotation.

Wait, are you guys taking away the letters for the Dozer names? How will we tell the difference between the T, K, and N then?
D6 and D6XE are all new ua-cam.com/video/26wZnyD__vE/v-deo.html
Maybe this will be sized for each of those? There wasn't any stickers on the machine and the front end has low cylinders like the N
Simplification of the dozer naming. More to come...you'll easily be able to tell the difference between the dozer sizes.

@@patrickbolin6569 Fair comment. The confusion was in the D6 range...D6K, D6N, D6T. www.equipmentjournal.com/construction-news/cat-dozers-name-change/
Animation and explanation stop at the ECM.... Thumb down.
Should be a good one.
I wanna try!
Two more days!!!! Get ready.

It will break down constantly.
actually less breakdowns

no big battery son.
