This model weighs in at around 140,000 lbs and features over 500 horsepower. It is not the largest dozer around, as there is a 750 horsepower class as well, but the D10 is still a serious dozer. Dozers of this size haven't been around all that long (perhaps 20 years) but they are very productive. This compares to the D9 class machine (the next size smaller) which has been around since the late 1950's.

Cat was not the first out with a over 500 horsepower machine--the credit for that goes to Fiat Allis with their FA 41 (big brother to the FA 31 featured on another page, but Fiat Allis is out of the giant tractor market, and Cat is dominating it. The enormous cost and logistical problems in moving these machines limits their usefulness to major mining operations, but there they shine.

The ripper and the blade are both off of it. Removal of these items it not technically difficult as the blade bolts on with only a few bolts, and the ripper pins on with a few pins and some hydraulic hoses, but the sheer mass size of the pieces makes it a challenge and requires that a substantial crane be available at the assembly site.
