Riding lawn mower

A manned lawn mower, comprising:

• a supporting portion for carrying a user;
• a rolling assembly comprising at least one rolling wheel;
• a rolling motor configured to drive the at least one rolling wheel to rotate;
• a cutting assembly comprising at least one cutting piece for cutting grass;
• a driving motor configured to drive the cutting assembly;
• a first energy storage device configured to supply power to at least one of the rolling motor or the driving motor, the first energy storage device comprising at least one first energy storage unit, the first energy storage device detachably mounted to the manned lawn mower and enabled to supply power to a garden power tool when detached from the manned lawn mower;
• and
• a second energy storage device configured to supply power to at least one of the rolling motor or the driving motor, the second energy storage device comprising at least one second energy storage unit,
• wherein a ratio of a total energy of the second energy storage device to a total energy of the first energy storage device is greater than or equal to 2 and less than or equal to 20.
