suppose you were operating somthing like a Cat D9 and the lower corner edge happens to hit something immobile.. does it stop the machine dead? can it bend the blade or is there some sort of shock absobing aspect that the manufacturer designed into it. Granted you would not be moving terribly fast. I know on smaller tractors with a bucket Ive had the machine start to "creep" to the side, pivoting on the immobile object.. just wondering...

It would just push it out of the way and you would never know it. Nothing can stop a 9.

We just rebuilt an old D9G for a guy first of the year from one end to the other. When we got done if you ran it into something that didn't move, it did like TD18 said, it would sit there spinning the tracks and digging two nice long holes, and 99.9% of the time that's all it's gonna do. Dad worked for the AC dealership back in the 70's and they had a couple machines came back with excessive blowby. The people were told to work them hard for the first few days to seat the rings but some of them couldn't do like they were told. The dealership didn't have any type of dyno to load the engine alone, so when they got the machine back together they'd take the it out back and put it against a tree, pull it's ears back, and let it moan. After it set there and spun the tracks for a while at max load, they knew the rings had seated before it ever left the yard. Needless to say they never had another come back with that problem. Of course that other .1% of the time you may break an end bit or the cutting edge or bend the corner of the blade, but usually if you hit somethig fast and hard enough to do that then like another post said, your probably gonna be shook up more than the machine.

Might break a corner bit, the only thing that immobile I can think of would be a rock bigger than the tractor and the corner bit would likely break a chunk off the rock. The D9's set up for pushing scrapers with the narrow blades have a bit of shock absorbtion but that's to pick up the push block easy. Later Bob

Depending how how good the grousers were, and how massive the object was, a D-9 has enough horsepower to just spin the tracks. The blade would probably not be bent, but I have seen stranger things happen.

Hi, DavR. Usually when a Cat D9, of whatever vintage, (or pretty much any other 'dozer) hits something that brings it to a complete and instant stop, it is the operator that gets the biggest shake-up, especially if there are a few knots (speed-type, not rope) involved. Most crawler tractors and 'dozers have a pretty awesome over-design factor built into them for just this reason. With all the best will in the world from the best operators in the world, there is no way to positively, 100% guarantee that they are not going to hit a buried or hidden obstacle sometime or other, unless they NEVER sink the blade into dirt. Stumps and rocks are the main culprits, but I have also encountered the odd concrete block where none were supposed to be and a couple or buried steel beams that somebody neglected to mention. Never been the same since my X-ray vision went on me. Hope this helps. You have a wonderful day. Best wishes. Deas Plant.

I have seen a new JD 850 used as a battering ram into pine tree stumps. The stumps nearly always win.
