Love the quad-tyred John Deere! 
JD wheeled tractors have certainly taken off here in the northern UK. Haven't seen any quad-wheeled ones like those though - they could be a bit on the wide side for our road network perhaps?
It would be interesting to compare the JD with the Cat Challenger next to it for haul speeds/loads carried/etc.

My bet is on the JD and centre steer being easier to change direction with under full drawbar load. After all, tracked vehicles like dozers are only glorified skid steers and drop half the pulling force during turns. Straight line pulling power depends on avaliable power and traction so I'll take the easy way out and say "It all depends on ground conditions"!! Having said that, for overall conditions, I'd take the JD or any brand of similar tractor.......C ya.........Ray

Those John Deere units have been "ran hard and put away wet". One several occasions they have drove them off a small incline fast enough to get all 8 tires off the ground with the pans behind them! (empty of course). That challenger has enough power with the C-18 engine to flat dig both 18 yard pans into the clay with ease. It is fairly hard on the tracks though, especially when running through a rock low water crossing. The John Deeres have paid themselves off many times over with the amount of soil they have moved.

You could probably take the outer duals off, but even with them on, the 9520 is only a little over 13' wide. You like those tires, take a look at these!:drinkup:cool2:notworthy
PS:mitchell2905 I think any time you use these tractors in an operation like this they get run pretty hard. Even the "scraper specials" John Deere has are still pretty much farm tractors... hauling fully loaded pans in 15th or higher gears is gonna take it's toll eventually.

The Deere's are the caddies of pan tractors. Our company has 30 or so big articulated tractors for pulling the 2 pans we have and big discs and land levellers... and the occasional double drum. But everyone that has taken a rip in our 9520 doesn't want to even look at their STX 435 again. As for our Challengers.... they have their good days and their bad days. But more bad ones if you know what I mean.
Our best tractor in the entire fleet though is the Caterpillar yellow painted 955 Versatile! Last year I showed one of our mechanics how to keep the ole Vers' from getting stuck in 2nd gear. They made a couple shift plates for the others and new life has been given to the beats. Oddly enough many a tractor operators don't really like me now. No more comfy Binders and Deere's for them now.

100' cultivator???????????????
Now, I dont think that a 9520 or whatever deere could pull a 100' cultivator. Mabey a 60 footer, but 100 is a little much, besides do they even make one? I know the big bud pulls a large cultivator, but I dont even know if thats even 100ft, and you cant even compare Deeres biggest tractor to the big bud, but I still agree with you that pulling two loaded pans in 15th gear is not much different then pulling a wide farm implement,
I beg to differ. Pulling any farm implement is a pretty much consistant drawbar pull. Pulling pans is a whole different ballgame, and many with the above posted attitude towards it have been educated on the true costs of moving dirt with a tractor and pan. Not saying it is not cheaper in the right conditions, but when pulling pans, you costantly load and unload the drawbar, producing shock loads, and the drag of pulling the pan through the ground is anything but a steady pull. When things are loaded up and unloaded, over and over again, it fatigues the iron faster than a steady rate load. This applies to all the drivetrain components, from the engine to the wheels, and everything between.
Again, I am not saying it doesnt work, but it is a much tougher duty on the tractor.

bananna farming CO in QLD AUS have some huge gear, we had a 64ft scarifier with an air seeder and it was a small one for the area,
i cant see the difference between a drawn scraper's shockloads and a (large) implement's shockloads when being drawn thru an uneven or what we call (melonhole) paddock, I have seen 400+HP tractor being run on triples (12 wheels) pulled sideways as a direct result of one side of a plow digging into a softspot or a (big bud) being pushed down a bitumin rd while pulling a 100t grain storage bin (both pulling and pushing stresses here)
I dunno, I most likely am wrong but i cant see it.
DEAS whats ur view on this???

Yep, exactly!!! You hit that wet spot on one side of that implement and before ya know it your going sideways! :drinkup

While I can't comment on the shock loads from farm implements (as I have no experience with them:beatsme), I will state this. The Scraper special 20 and 30 series John Deeres (ie 9520 or 9530) have heavier hitches and beefed up axles, because of the fact that they are pulling scrapers.
ANother thing I thought about today, and really don't know if it has any affect, all the weight from the pan is either at the rear of the pan or the tractor, on like a disk, the fulcrum for the weight is pretty much near the center to lift and lower the implement. While the fulcrum of weight on the pan is in the back of the implement, part of why the extra weights are towards the front, when you're hauling and hit a bump you can feel the Pan's weight pushing on the hitch trying to bounce the from of the tractor up and down.... so fun:Banghead.
This might be why I'm inclined to think that the construction field is more abusive on the tractor... :beatsme:drinkup

Think that the reason that the construction side is more abusive to the equipment is that the farmer that owns the tractor also drives it. And usually if the tractor is in the upper gears he is moving out on a improved road rather than freshly stripped topsoil.

Hello mr Deere9670
Cool pics you have in your avatar. :drinkup:notworthy
Do you have some more of that one?
I like to se more.. :usa

Scrapers are sure harder on drive trains, especially back diffs and axles, simply because of the weight transfer to the back axle when loading. If they were only draging dirt around without closing the apron a comparison could be made to pulling farming impliments. Why would scarper manufacturers like myself try and put the pull points so far forward and low if not to try and transfer some of this load towards the front axle. One of my customers has had a heap of trouble with his 9520's with diffs and tranny's not copeing well with the tandem scrapers. He has to change the wheel bearings every 2,500 hours in the same way we had to do our 8850 axle bearings many years ago. Changing gears under load is probably the biggest cause of drive train failure - bring back the Allison automatics I say. I'm actually looking into putting one into an STX because they seem to be having no axle issues with tandem scrapers here..........
I would have to say that pulling pans is way harder on a tractor than farming ops. Pulling large implements in the field does make alot of work for a tractor, but it is a usaually a nice steady pull. Pan tractors get a hard pull in the cut, which isn't so bad. But then they get shifted into top gear pulling 36 yds of over sometimes not the smoothest roads. And I think this is what really tears up tractors on pans. And you usally get some bouncing going on along on the haul that can bounce you right into the roof if your not careful and get'er slowed down. When you start bouncing so hard that you can see air under 8 tires of the tractor, you are bound to bread something.

Scrapers aren't that popular here, but when we do use pans, they are usually towed by a Bell articulated hauler. These are made by Bell, not Deere.
