why no hi-drive?

Time will tell, but once agian Cat may have just found the new future for heavy equipment of all sizes.. If the components are rugged and reliable I can't see a downside for diesel electric drive in many machines. I would guess change out of components would be faster, less mechanical drive parts involved, a better torque control and finer tuned controls period, also fuel savings, better engine life, and the list goes on. When you think about it a fine tuned electric drive system could relay be the way to go in all kinds of applications. From skidsteers to mining trucks, I think its going to go bigtime.

Interesting to see one of the photos i have seen had what appeared to be 1:50 scale Norscot model sitting on the blade.
Will be interesting to see what other product lines get the Electric treatment over the coming years.
RG only needed modern controls and it would have perhaps sent earthmoving down another path all those years ago, not to take anything away from the revolutionary designs he came up with. Cat have done what they do best, look at emerging ideas, sit back do the R & D and bring it to market at the right time.
Alot of questions being asked as to why low drive, well who,s to say but low drive tractors in the smaller sizes have been back in for a bit now and i think you will find the high works best with a bogie undercarriage which the smaller tractors never had. Making the smaller tractors than D8L elevated sprocket all them years back was to capitalise on what had become with the bigger stuff and is the product of marketing-bottom line.Nowadays with a number of smaller TTT manufacturers the VOC rings load and clear and Cat have responded, will be interesting to see what the counterattacks comprise of. From all the press i have seen so far it seems the D7E has stole the show, but the big test will be the market acceptance.

From what I saw Volvo is hot on their tail with diesel electric machines and making them "green".

What I find intresting is that single cylinder to raise and lower the blade.

I think the diesel electric design is promising. I am however wondering why they decided to go to the single cylinder. Is the other cylinder no longer neccessary?

Looks to me like that photo of the guy trying out the controls is afraid of getting an electric shock if he touches them maybe he should try wearing rubber gloves .The only time I think he will get a shock from this machine is when he sees the sticker price if Cat stays true to it's pricing policys.I also wonder where the optional Energyiser bunny decal is
