What is the reason for using planetary wheels on the front instead of cheaper free rolling wheels like on the back?

I am sure the wheels were cheap from the scraper that donated most of the rest of itself to the conversion, the planetaries would have all the internals removed so are free rolling in every sense of the word even though it still looks like a planetary.

They sold almost all of the 9's and pans this last winter because of the slowdown. We have alot of bridge and paving work but dirt work and pipe work(which I do) are pretty slow right now, about like everyone else.

Undercarriage wear

Awesome..... but would hate to finance the U/C (s)

As long as the tractor stays in forward and not reverse I'd expect fairly long undercarriage life in most ground conditions. It's the reverse travel that shortens u/c life.

39.5 x 35 scraper tires are also very expensive to replace. At least tracks aren't succeptable to punctures, sidewall or spin cuts.

That kind of setup gets used here lots except it's with D8H's and D8K's some are still cable too. I have seen the occasional D8N or D8L but it works great heavy clays soils like here where we have gumbo like you've never seen before. Some of the old guys I know that run them say they're really good with trimming work since your not bouncing around like a rubber tire buggy.

Not necessarily true, McAninch had a hard time keeping up with all their undercarriage break downs. Then the operators spinning the tracks to get loaded. Most of their 10T's were slick pads. Running a dozer in 3rd gear is not easy on it. When the D10's were cutting they still needed another dozer in the cut to rip for them and some cases push them.

Or eliminate the tires...

What is the ride like on those 9630's Kolb runs with the tracks over the tires, and also does it make it harder to turn. I have seen them run that setup on 67 HWY in southeastern missouri and they are running them now here in osage beach missouri. I have been curious about them as I have never seen that setup before.

well one word ROUGH! No it doesnt effect that tractor at all same abilities. Sucks a little power away as you can imagine. The first one we had I ran to make sure if it was all right. Jeff Kolb came out and rode with me for an hour and talked to me a little bit. He said wow these are kinda rough I just looked at him. He only had to be in there for an hour I had it all day. They have done a few things to make it ride better but they are still kinda rough. But they work Ill give them that, cheap to run and no more tire repair. I thought there was no way it would work when Jeff told me about it but it does. Give credit to the man for thinking outside the box thats for sure.

I would say you will have diff/transmission problems with that Deere before too long. It is designed to work with tyres where wheelslip will protect the driveline, here you have a situation almost 0% wheelslip & extremely high torque loadings

yup defiantly, but heres the catch they bought the extended warranty or some crap and Deere warranties them 110 percent. Cab mounts going out to soon, tractor breaking in half (seen this happen), shatering the front windows out, bending the frame, breaking differentials, everything warrantied. this is all coming from the guys in Moline telling the dealer to warranty everything at all cost. Even gave us 26 inch flat screen tvs with camera's watching the cutting edge on your 2nd and 3rd pan so no more guessing if your cutting or not. All at John Deere's expense.

Sounds like that is a great deal for a company. Deere must be trying to slow Cat's business in the towed scraper market.

Yup, they pretty much giving those John Deere away. Even TJ Lambrecht has like 30 of them and sold their Challengers. Caterpillar let Kolb Demo one of their mt975's and they put tracks on it. The head Mechanic for Fabick came out and said WTF take those off. Cat said they would void any warranty immediatly if we bought their tractors and put those on.

On another subject heard Emery and Sapp was able to pick up another section of 54 highway. Beat Kolb by a little bit, so guess you all are getting a little work.

Do it every day here with D8K's and No. 80 Cat pans. Awsome combination. Did have to put a D7G pushing on the last job here cutting limestone. Still was cost competitive.

He more than likely knew about the same idea that cat put on their large wheel loaders in the late sixties early seventies,was it called Dystred track or something like that?? I 've seen it mentioned before on this forum.

I forgot to mention but those pullscrapers have probablely been converted from 621/627's

Pretty sure those are dystreads, looks like they recentred the wheels. We ran them and the beadless tyres whis are a never version of dystreat on our 980Bs and 988Bs and they were great in the rock, but the dystead would go through bushings like mad,the beadless had no bushings.

That setup looks impressive, would like to have a go in one.

I saw a D7H pulling a scoop here in NZ the other day, was building up tracks on a dairy farm, only problem was the 2 or 3km round trip to the pit! what a retard!!
