A tracked loader is an engineering vehicle consisting of a tracked chassis with a loader for digging and loading material. The history of tracked loaders can be defined by three evolutions of their design. Each of these evolutions made the tracked loader a more viable and versatile tool in the excavation industry. These machines are capable in nearly every task, but master of none. A dozer, excavator, or wheel loader will out perform a tracked loader under a set of conditions, but the ability of a tracked loader perform almost every task on a job site is why it remains a part of many companies' fleets.
