All our Track Loaders have automatic bucket controls that let the bucket rise to pre-set dumping heights and return to pre-set digging angles for fast cycle times. The rear engine design of our larger Track Loaders - the 953C, 963C and 973C - allows the engine to serve as a natural, "working" counterweight for increased stability and visibility and good weight-to-power ratio Since Caterpillar serves customers with different requirements in all regions of the world, we build several different configurations of Track Loaders, so that you can choose the machine configuration that best meets your needs.
