What type of armored wagon did Leonardo da Vinci design with blades on its wheels?

Leonardo da Vinci designed a scythed chariot, an armored wagon fitted with blades on its wheels.

The concept shows a vehicle moving through opposing troops while rotating blades extended outward from the wheel area. Its purpose was to combine transport, protection, and close-range attack in a single battlefield machine.

Leonardo’s scythed chariot should not be confused with the ancient scythed chariots associated with Persian and Hellenistic warfare. His design belongs to Renaissance military engineering and was presented as a mechanical concept rather than a documented working weapon.

The proposal also reveals the limitations of translating a dramatic mechanism into combat. Steering, control, crew safety, and the danger posed to friendly troops would all have been serious practical problems.
