But just the fact you got someone's attention that high up the food chain is very cool!

And BTW, the patent on Cat high drive undercarriage system expired awhile back and they never renewed so anybody can make them now.
I've been told new dozer are back to low drive and electric driven motors. No more torque converter , tranny just electric motor to a final drive!
That's all for smaller dozers like D6, 7. I'm sure the big d10 and 11 will remain high drives.

That's interesting Mario, I didn't know that. Thanks for the info. I'll bet that new configuration is an improvement. Is that in production now? I understand electric drive can produce some great power. I guess that's why locomotives run that way. Anyways thanks for sharing the knowledge.

Memory ain't what it used to be. The electric dozer was announced around 2009. And it's only a D7E version.

There's a new D6T in our shop right now and unlike the old days, it's not a high drive and is low sprocket with hydraulic motors / final drive. Again, eliminating the torq and tranny.
Machines are changing so much it's hard to keep up!

Sorry, don't mean to high jack your awsome news thread but here's one more new innovation that will blow your mind!
