Here's another picture of it apart, and ready to transport. Sorry, i don't have any other info to go with the pictures. They were sent to me a couple years ago, and i don't remember there being anything about the crawler with them. Robert

Hi, JimInOz. Can't help you with any of the SxS D9G set-ups still running nor any of the H's or the Dual D9 machines. I think with the advent of the D10's, most people who had them figured they weren't an economical alternative any longer and split them up. However, the SxS D11 R is alive and well in some-one's imagination. See the link below. I too would like to hear of any still running, either SxS or Dual (Quad - I've never been able to fugure where the term 'quad' came from, there's only two of 'em, not four.) D9's running. You have a wonderful day. Best wishes. Deas Plant.

TERM QUAD is probably in REF. to the tracks, two dozers = 4 tracks. Just a guess though

Hey DEAS...nice looking model,but I still think the conventional type track looks better.Never got the same thrill looking at a HI TRACK,as looking at a 9G ,8H etc.Hope you're busy up there..this building boom is crazy everywhere! Thanks guys...keep those sightings coming.

Hi, JimInOz. I'm with you about the real thing. One thing I never got to run but I can imagine what it would be like. I've spent enough time with ONE D9G or H under my backside to be able to do that. And I've still got a strong attachment to those old flat-track slow-bangers. We're getting pretty d**n good at our 'lizard drinking' impressions. 9 Cat track loaders - 941's, 943's and 953's - two 20-22 ton excavators and a Cat D5B dozer, all flat out, 8-10 hours a day, 5 1/2 days a week. Sub-divisions springing up all over the place and 'Mexicans' coming out of the woodwork. The annual UBD street directory update is out of date before it hits the shelves. It's been like that for 2 1/2 years. Make hay while the sun shines? You have a wonderful day. Best wishes. Deas Plant.

Haven't seen any in the Carolina area, but like you I have seen the brochures. We rebuilt a D9G from end to end first of the year and had to get a parts manual for it. The dealer threw in a side by side 9G manual that they had missordered just to get it out of his way. Watching the ole girl work when we got done, it really makes you understand how much power these old machines have and just staggers the imagination as to how two of them together would be..... I'm only 35 so I'm too young to have seen alot of this stuff first hand when it was new, but how I would love to go back and experience it.

Don't recall where, but I've seen old Cat publicity photo of two large machines (D8's or 9's), one operator/one slave unit pushing long (40 ft.??) blade apparently mounted on gimbals (one was considerably uphill and in front of the other) used for contouring reclaimed strip mine land. If memory serves same brochure showed two D8's (both manned) using large battleship anchor chain equipped with large rolling balls as swivels clearing smaller trees and scrub by driving into it side by side but at some distance apart letting chain take out stuff between them.

Hi, Tom Railsback & Smallercrawler. We used the two 'dozers and anchor chain extensively DownUnder, for clearing anything from scrub right through to quite heavy timber. I think most contractors down here gave the ball away very early in the proceedings because it kept the chain a bit higher and caused a LOT more break-offs leaving the stumps in the ground. Chaining also became a 'winter sport' in many areas because the ground was a little wetter and the trees pulled out of the ground easier instead of breaking off. I once cleared 6,000 acres of scrub in five days with two Cat D8H's and 600 feet of 2" chain, 1,200 acres per day, cutting around 400 feet wide per pass. We had to wire 20-25 foot long sticks with flags on them to the timber canopy legs to be able to keep track of each other in the scrub. We usually allowed around 100 feet of chain for each 'dozer on top of the width of cut in scrub, a little more in heavier timber. One other trick we used in heavier timber was to have a third 'dozer equipped with a tree pusher bar following the chain to push over any larger trees that stopped the two 'dozers with the chain. That particular job on the 'chase' 'dozer would have to be one of the less desirable tasks for any 'dozer operator - climbing over all the flattened trees and expected to be where the big tree is within seconds. Notta lotta fun. Sometimes the 'dozer on the outside was fitted with a tree pusher bar instead. The idea with this arrangement was that the operator on the inside would look for any trees that he thought might be a problem and cut around them, leaving them for the outside machine to push over on the next pass. You have a wonderful day. Best wishes. Deas Plant.

Bureau of Land Management used to do the chain thing here in USA on sagebrush to improve the range. Don't think they do it anymore.
