Abstract
A lawn mower may include: a blade configured to cut grass; a grass collection unit configured to collect the grass cut by the blade; and a fan configured to generate an air flow that blows the grass cut by the blade toward the grass collection unit. The grass may include heavy grass cut long by the blade and light grass cut short by the blade. Among the heavy grass and the light grass having entered the grass collection unit, the grass collection unit may be configured to collect the heavy grass and discharge the light grass out of the grass collection unit.
