A fully-adjustable lightweight trimmer attachment assembly ( 10 ) broadly comprises a wheel ( 14 ), a rod ( 16 ) extending from the wheel ( 14 ), and a mounting mechanism ( 18 ) for rotationally mounting the rod ( 16 ) to a trimmer ( 12 ). The rod ( 16 ) preferably includes an axle section ( 16 a) through the wheel ( 14 ), a trailing section ( 16 b) perpendicular to the axle section ( 16 a), a centering section ( 16 c) parallel to the axle section ( 16 a), and a vertical section ( 16 d) aligned at ninety degrees to the centering section ( 16 c) and at sixty degrees to the trailing section ( 16 b). With the vertical section ( 16 d) vertical, the trailing section ( 16 b) forces the wheel ( 14 ) to follow the vertical section ( 16 d), providing a castering effect. The mounting mechanism ( 18 ) includes a rod mount ( 30 ) rotationally secured to the vertical section ( 16 d) and a shaft mount ( 32 ) operable to be secured to the trimmer ( 12 ) and rotate about the rod mount ( 30 ).
