Deere 850K vs. Cat D6

Here a Deere 850K with a six way blade clearly outperforms a Cat D6R with a SU blade. The 850K starts the push later, carrys a larger blade full of material and finishes the push at the same time.

Not to mention the fact that a High track machine will have less wear and tear on teh drive sprocket and bearings. Whe weight of the machine NEVER touches teh D6's drive sprocket.

@goofyexponent

please explain how elevated sprockets reduce wear on the sprocket and "bearings". If that is really true the boys in Peoria must not know what they are doing with the D6K and D7E!!

Who cares which machine really won in one push off pass. I wouldn't doubt a competitive sized dozer from any manufacturer could out-perform a Cat on a good day, but when owning one of these machines, you have to look at other factors beyond the performance. When either of these machines need repairs, do you think Deere will beat the response of a Cat dealer, I doubt it. As well, in 10 years, which machine will still be working, at 20,000 hours would you rebuild a Deere, or buy new?

@waults

dealers vary across the country. I know for a fact there are areas that the Deere dealer will smoke the Cat dealer on responsivness, parts availability and customer service. I also venture to say that in this size of dozer...MOST people will not run these machine to 20K hours...furthermore...MOST people that may run them to 20K will not bother performing a machine relife choosing rather to replace the tractor, no matter what brand it is

The deere was just in a higher gear that is all simple

@durby07

With the hydrostatic drive you can set a higher speed and when there is a light load it will run faster (like at the beginning of the push) then when the load increases the transmission automatically adjusts and keeps the engine in just the right RPM range without requiring the operator to shift (like a powershift trans)

[lpdemolition]

The D6 starts with a loaded blade... the 850 starts empty... of course it will be faster... but you notice that once the blade loads, the 850 is spinning its tracks and has lost ground on the 6... The D6 carried the load the full distance.. The 850 did not.. Trying to trick people only makes you look bad.

i guess that explains why there are so many john deeres in the mining industry..... NOT

@goofyexponent Ah, I don't know much about this type of thing but that makes alot of sense. Always nice to learn the reasons behind different technological builds. Thnx

[goofyexponent]

@jeepncj Like I said, the weight of the machine never touches the drive sprocket. Would you rather rebuild a drive axle, or just drop new bearings in the idlers? All I am saying is in rocky terrain, like I work in, the high tracks rule.

[alvie2]

looks about even to me too. Clearly.

[Wildmanhodge]

Looks like they're about the same to me.

[rogueorange]

@jeepncj a hydrostatic driven machine has no transmission. each track is driven by a hydrualic motor. which in turn is powered by a pump. that is the simple explanation. there is no transmission

you have to take inconsideration that the D6R is a LGP and the 850k isnt also look at the grousser wear difference also the D6r LGP come with a std 13.1ft blade and the 850k with a 6 way package has 10.5ft blade and even though the 850k is starting later but it doesnt really start pushing till it catches up to the cat! the 850 has an advantage over the cat being that the cat is the lgp, at :50 seconds u can see the D6R tracks are pretty wore out so im with the cat on this one
