Abstract
A pair of U-shaped sheet metal brackets are fixably mountable to the rear vertical wall of a power lawn mower deck to opposite sides of the deck or to the top wall of the deck with the open ends facing end other. Bent wire rod angle arms have their free ends of arm first branches pivotably mounted to the base of the U-shaped sheet metal brackets for pivoting internally of the bracket legs limited to contact with the legs of the brackets and their other branch has ends fixed to an axle rotatably supporting a roller for rotation horizontally about its axis and between the angle arm branches at the rear of the rotary power mower. Pivoting of the angle arms limits vertical travel of the roller to several inches to prevent the operator's foot from being projected relatively beneath the mower deck and into the path of the rotating blade of the power mower. Changing the angle of inclination between the branches of the wire rod angle arms permits alternate mounting of the U-shaped brackets to the rear wall or top wall of the mower deck.
