    I was wondering if anyone knew any more info on these? I only looked over the D3. It looks like they gave it a little more power, but it is heavier and a little bigger. The cab forward design is nice, and it looks like it's got great visibility and creature comforts. The blade shake button is cool if it works.

    IMO, Cat is long overdue for a revamp on their finish dozers. I figured they had something in the works. I hadn't heard anything on these until I stumbled across this yesterday.

    So what's they scoop? Anyone (cough, Tiggerator, cough) :) have anything they are allowed to add to this, especially a release date? Or will this be Top Secret, Area 51, X-Files information that we won't see for a while?

    I read over the brochures online yesterday, they look super sweet in the cab. The new joysticks are definately a needed improvement, Deere had been stomping Deere with the 550/650H and newer dozer steering control stick. The newly designed stick looks to be much more comfortable and easier to use.

    Komatsu's D51, while in D6K category, looks to be an awesome machine. I saw one on a big freeway job just north of here about a month or so ago, looked super sweet. Cat's K series should be up to this par I would hope.

    I actually have no idea... the dates on these tractors have fluctuated a ton. To give you an idea, I operated a D4K prototype in 2005... two years ago... and it was already in pretty decent shape (no serious redesigns followed).

    The new K series D6 from CAT is a work horse, I was really impressed with the balde shake. I had the chance to run a JD 700J, but not much can be said about it compared to the CAT, CAT is American made whereas the JD is a re-painted Liebherr, but German quality was damn fine though. The D-4 Hystat I run is a great machine but all these little dozers all need the same torsion bar set up that the bigger boys use.

    Mmm careful... the 700J is not a repainted Liebherr and the Cat is not American-made. :)

    The D6K is manufactured in Grenoble, France.

    Uh-oh, seems CAT reps here are a little over educated, but however, here is the proof of the JD/Liebherr similarities

    John Deere:

    Liebherr:
    http://www.liebherr.com/downloads/PR714-GB-TB.pdf

    Same deal as the Hitachi. Deere builds very little of their own heavy equipment, some of the models they do "build" according to the local reps here are the TLB's (the 110 might be Yanmar's, 310-710) 450-650 dozers and all skidsteers.
    The rest are from Champion (graders) Hitachi (excavators and front end loaders and maybe the older smaller dozers) Moxy (ADT's) Liebherr (Larger dozers and tracked loaders)

    But correct me if I'm wrong.

    The 700J is a Deere machine, just as the 700H was a Deere machine. The 712B did not become the 714 on Liebherr engineering; rather, Deere sources its 700J to Liebherr (just as Liebherr sources its track loaders and 744 and 754 dozers to Deere). But regardless: the 700J is an American product. There may be more German engineering than, say, in the 300-series skid-steers, but this is one machine that Deere builds for Liebherr.

    The graders are not Champion graders.
    Hitachi does not product Deere's front-end loaders. Those are Deere products by-and-by.
    Moxy doesn't build Deere's ADTs; Bell does.

    Now I am corrected, Bell is the name I keep getting mixed up on, although I have seen a few older grey market Hitachi front end loaders that looked closely to Deere's.

    Also on a side note, when I ran the Deere 700J, the feature I found most impressive was the self leveling of the blade when you angle it left or right, on a 6 way PAT blade, if you put the blade with the cutting edge on a flat level surface, and angle the blade L/R, as you pull up or push the blade down while pushing, you have to constantly correct the side angle as he outer corner of the blade will always dig in deeper than the opposing side, Deere's hydraulics did that automatically, like the hydraulic self leveling feature on most skid steer loaders, I found that very useful when windrowing material to one side.

    (I should note that I didn't mean offense or anything condescending in my posts... they were just typed hastily. I apologize if I came across as either of those.)

    I'm trying to verify the point about the 700J.
