Abstract:
A wheeled attachment for a weed trimmer, said attachment comprising:(a) a shaft; (b) a rotational member attached to said shaft; (c) a coil spring in communication with said shaft and said rotational member, wherein said spring biases said rotational member downwardly with respect to said shaft, and wherein said spring has a force constant sufficiently high that said spring prevents the trimmer head from striking the ground during normal operation, but sufficiently low that an operator may depress the trimmer and thereby strike the trimmer head against the ground in order to release trimmer line from the trimmer head; (d) a wheel attached to said rotational member; (e) a bracket connecting said shaft to the weed trimmer, wherein said bracket is adjustable with respect to the angle of said shaft to said trimmer; and (f) a cylinder fitted circumferentially within said shaft, wherein said coil spring fits within said cylinder and a portion of said rotational member passes through said cylinder.
