Power lawn mower

摘要

A power lawn mower has a cutter blade mounted on a vertical output shaft driven by an engine and extending substantially horizontally, and a housing covering the cutter blade. The power lawn mower has a throw-out plate for throwing out the grass cut by the cutter blade, the throw-out plate being mounted on the output shaft above the cutter blade within the housing and extending substantially horizontally. The throw-out plate is angularly spaced from the cutter blade and positioned therebehind in the direction of rotation of the throw-out plate. The throw-out plate is shorter than the cutter blade and substantially flat. The throw-out plate includes a throw-out arm having a leading edge in the direction of rotation thereof and curved progresively rearwardly in the same direction from a proximal end of the throw-out arm to a radially outward end thereof. The housing has a front half portion pivotably mounted on a housing body for upward tilted movement about an axis inclined with respect to the direction of travel of the power lawn mower.
