self-propelled
Needs no pushing
Self-propelled describes something that moves under its own power rather than being pushed, pulled, or towed: a self-propelled lawn mower, self-propelled artillery.
The term distinguishes vehicles and equipment with built-in engines or motors from those requiring external force.
