Abstract
A lawn edger attachment for moving vehicles consisting of a rolling coulter blade carried for rotation on a horizontal axis at the rearward end of a trailing arm pivoted at its forward end to the vehicle on a generally vertical axis. Mechanism is provided for pivoting the arm vertically to raise or lower the blade, and also to cause the arm to trail normally at different lateral spacings from the vehicle, although said arm may also be pivoted laterally by manual force. A broom or scraper is also provided, in trailing relation to the blade, for sweeping the cuttings of the blade either to the pavement, or to the grass, adjacent the juncture line between the pavement and the grass.
