I look forward to more postitive discourse on this subject matter. They are now wanting to produce farm related equipment and combines. Interesting enough CAT is now making or starting down the the same misadventures that IH and AC made. Is FA a good machine now, I would question that, but you know they have taken a lot of market share from CAT and so has Komatsu-IH. They lost not because they were bad machines, the farm economy ulimately sunk the parent companies and in some cases poor management. Compare like machines within the same era and the results will be different.ĪC is gone, so is IH, Dresser. Your qestion begs other questions as to how to arrive at the best dozer. The HD31 with a few less horse did not have that problem. They had so much torque they were know for shattering their final drive shaft. I can take an FD51 or HD41 and tow a Cat D8 all day long and the the only thing it could do is spin it tracks. The fact that the HD11 is junk is as much a function of maintenace and use/abuse of the machine and the fact that the technology is so radically different.Ī little TD6 will push an DD HD11 all over the place if the grousers are worn to the nub, the rails are worn and the sprocket is bad. If it is a straight HD11, you have a DD drive trany and the 76 will have a TC, with a mulitplier of 2-3x on the torque. You are comparing a 1976 tractor with one made in between 1955 to 1960. When it happens just take that to a machine shop and have them fix it. I had a shaft that was damaged and went to a machine shop and had it fixed for a fraction of the price that it would cost for CAT. Now I have never had a nut cross threaded to date. For a long time they produced the world's largest dozer. They were the first with fully lift out on the steering brakes.ĪC was the first to succesfully produce a production machine with over 500HP. AC was the first with Unit construction which made it very simple to work on the drive train with out full disassembly. You forgot to mention the fact that AC was the first to produce permanenatly sealed rollers ect. If we compare tractor to tractor when it was built, the AC had many innovations. I compared close to same generation of machine. Just as bad as my AC except that roller shells could still be bought. I almost made a mistake of owning that machine. Take the 933F and try to find a truck frame or the pinion shaft-which was a major failure point on those machines. No fun to rant and rave in an all CAT world.ĬAT is not so hot on parts availablity either. Remember this board is for a wide variety of machines and individuals having crawlers. He would not trade it for any CAT of that era. A good freind of mine has run CAT for 30 years and almost every CAT made and a wide variety of AC and IH equipment over those thirty years. So I guess your CAT's longivity is not that high. I do not see a whole lot of CATs that age running around and in production use. My father-in-laws 1947 TD9 beats that by 29 years and we still use it. I know in Idaho where there is an HD9 still in active use in a quarry. I now have a full new UC under it and it is almost ready to go. Beats it by 15 years or more and it is still running. Your qestion is so vauge that any discourse on this subject matter is or can be factually correct. You did not ask, who still had parts available? Who was still in business? How fast I can get the parts? Those are substantially different questions? You did not state or ask today. You posited what was the Best Dozer Made?
