Lawn mower

Abstract

A lawn mower includes a cutting device placed underneath a mower deck housing that surrounds the cutting device. The lawn mower further comprises a grass outlet in the mower deck housing. The outlet is leading cut grass via a discharge chute to a bag where the grass is collected. The end of the discharge chute is provided with a door that closes the discharge chute when the bag is removed from the lawn mower. The door is rotatable around an axis parallel to the axial direction of the discharge chute and automatically rotated to not cover the end of the discharge chute when the bag is secured to the lawn mower.
