Let me list the appearance features of a large excavator for you:

Color: Excavators are usually yellow or orange, but may be other colors.
Wheels: Excavators have large, strong wheels that allow them to move over rough terrain.
Digging Arm: Excavators have an adjustable digging arm that can be moved up and down. This arm has a digging device (bucket) at the end that can dig the soil.
Other details: Excavators may also have other details, such as the manufacturer’s logo, model name, and safety symbols.
