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.
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!!
@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.
@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
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?
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
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
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)
@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
OK, so to get this right, a brand new 205hp 850K with a 5.8 yd3 blade appears to be pushing about evenly with a at least 6 year old 185hp D6R with a 7.3 yard blade. I do like the "run at it" approach to get the blade loaded. Also fun to watch the 850 spin out with those torquey hystats. I guess your point is that the Deere has finally caught up with what Cat was making 6+ years ago? Makes sense, I suppose. I say chain 'em up and watch the fun then!!
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.
you honestly can say that at :21 that the Deere DOESN't have a large blade full and ISN'T in front of the Cat? This this is the point, the Deere started after the Cat and in 21 seconds was in front of the D6 with a larger load. Please tell me where the 850 is spinning and looses traction. I told see it.
Look at the video.. The John Deere 850 starts with an empty blade.. This machine has a hydrostatic drive train.. This means that it will go as fast as possible with it's power output vs the load.. The 850 takes the lead by 10 seconds, and is almost a tractor ahead by 17 seconds.. but once it has an equal load to the D6 .. it then looses its advantage and it looses its lead.. by the end they are neck and neck... and at this point it is the one who has the best traction...
Now the John Deere is brand new, so the grousers are in perfect factory condition.. The D6 has been on the job so there is no telling without measuring what is left on this undercarriage condition without measuring it .. the grousers could be worn an inch or more and we would not be able to tell in this video... And as far as spinning, the 850 spun at 30 seconds. You can even see the machine lift as the operator raises the blade at this time, and again at 43 seconds..
I have been a heavy equipment mechanic, an operator and a sales man for heavy equipment for over 25 years now and I am not saying that CAT is always better.. What I am saying is that by this video and its end result... you are not matching apples to apples.
@lpdemolition Wtf are you saying the CAT may have started with a full blade but the Deere started at the same point as the cat just a few seconds after, you make no sense just someone trying to defend cat and make it seem it was unfair when cat had the advantage
first off the Cat's blades capacity is almost a full yard more than the Deere. Besides that, a dozers integrity isn't measured by how fast or how much dirt it can push. It's a combination of many things. For instance, take some undercarriage measurements and you'll see that the Cat is a far better engineered tractor. Don't get me wrong Deere makes a lot of great equipment but hands down the D6T will push far more dirt in it's lifetime than the 850K.
@CatRep1377 mostly because the lifetime of hydro drive is quite short with a huge expense at rebuild. Until they fail, the deere is a very active and productive machine. Just don't be the guy who owns one when it goes down.
could also be that typically mining sized tractors start at the D8 size and go up from there. Deere's largest tractor is a 1050J...which is a D8 size. So it does make sense that there are more Cat and Komatsu dozers in mining. This video doesn't show mining sized tractors nor does it show a mining application.
need to put the same op in both machines. then call it a fair fight. i've run both deere and cat and it doesn't matter which machine i can still do the same amount of work in a day
What I didn't get video of was the next day when a brand new D6T was brought out and ran side by side just like this with the same result. At the end of the day the 850K stayed and Cat was hauling their machine back to the store.
@jeepncj We are supposed to get a 850K this week to work in a very thick heavy clay we have a 6R Lgp and a D6m working there now we will see how it stacks up

You have to love the new machine with full grouser to the worn off D6.
And the Deere lifts his blade when he slows the cat keeps it buried.
Dont get me wrong I really like Deere dozers but I dont see how this shows the 850 out performs the D6.
