On the end of the stick is usually a bucket. A wide large capacity (mud) bucket with a straight cutting edge is used for cleanup and levelling or where the material to be dug is soft and teeth are not required. A general purpose (GP) bucket is generally smaller stronger and has hardened side cutters and teeth used to break through hard ground and rocks. Buckets have numerous shapes and sizes for various applications. There are also many other attachments which are available to be attached to the excavator for boring ripping crushing cutting lifting etc. Excavators in Scandinavia often feature a tiltrotator which allows attachments rotate 360 degrees and tilt +/- 45 degrees in order to increase the flexibility and precision of the excavator.

Excavators (hydraulic) are heavy construction equipment consisting of a boom dipper (or stick) bucket and cab on a rotating platform known as the "house".1 The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid with hydraulic cylinders and hydraulic motors.2 Due to the linear actuation of hydraulic cylinders their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements.
