A string trimmer assembly includes a trimmer head rotatably driven by a drive shaft and defining a cavity, a spool supported in the cavity of the trimmer head and operable to support line to be dispensed, which is dispensable though an opening in the trimmer head, and a bump protruding from a distal end of the trimmer head. The bump includes a wear surface on a terminating end of the bump, and the wear surface and the opening define a cutting height.

The current invention is a Riding Lawn Mower Lawn Trimmer Attachment that can be efficiently attached to at any riding deck. It can also trim at an angle. The current invention has a trimmer which has a trimmer guard, an extender rod, and an adjustable angle bar to control the angle of the trim heads. Trim heads, trim cords, a drive system which in the preferred embodiment is a pully system attached to the mower drive pully, a support and a hinged connection to the lawn mower.

A string trimmer attachment assembly for a lawn mower includes a deck attachment mount; a turret mounted to the deck attachment mount about an axis; a trimmer head; a first arm mountable to the turret, the first arm adjustable along a first axis; a second arm mountable to the trimmer head, the second arm adjustable along a second axis; and a coupling to connect the first arm and the second arm such that the second arm is transverse to the first arm.

An integrated trimmer device for a lawnmower includes a coupler securable to an axle wheel of the lawnmower along a longitudinal axis of a bolt, the coupler comprises a gear system; a mounting bracket secured to the coupler; and a trimmer mount secured to the mounting bracket by the bolt at a desired rotational position defined by the gear system.

A lawn trimmer (100) comprising: a powered cutting tool (112) comprising a motor operably coupled to a rotatable cutter holder (120), the rotatable cutter holder (120) being operably coupled to a cutting piece (122). The rotatable cutter holder (120) has a forward side and first and second lateral sides. A guard (116) is configured to extend substantially from the first lateral side to the second lateral side around the front side of the rotatable cutter holder (120). The guard (116) is configured to provide space for the cutting piece (122) to rotate freely within the guard (116) and is an apertured barrier that provides a protective buffer between the cutting piece (122) and a ground surface, thereby preventing engagement of the rotatable cutter holder (120) with the ground surface when the powered cutting tool (112) is translated over the ground surface.

A trimmer head for use with a string trimmer including a drive shaft includes a housing rotatable about a rotational axis. The housing includes a main body defining a cavity, and a cap removably coupled to the main body. The trimmer head further includes a spool supported in the cavity and operable to support line to be dispensed, a retainer positioned between the housing and the spool, and a nut positioned within the spool and configured to drivingly couple to the drive shaft.
