Abstract: A device for edging and trimming a lawn particularly around the base of a mobile home is disclosed which includes an elongated strip-like base member having an integral upstanding leg member and a second outwardly and downwardly extending flange which terminates a short distance above the base member. The flange is flexible and the assembly is adapted to be placed upon the ground on a lawn at a position where it is desired to trim the grass. A lawn mower may be moved along the base member to deflect the flange member inwardly toward the leg and cut the grass at the same height as grass throughout the remainder of the lawn. The device also includes means for locking the base and leg to the bottom of skirting which may extend around the periphery of the mobile home. The device is preferably formed from extruded PVC.
