Do you have a thick weeded area to trim? One that's seemingly too large for a handheld string trimmer, but too thick or rough for a lawn mower?
Wheeled string trimmers, also called walk-behind string trimmers, are rugged string trimmer heads attached to a walk-behind frame with two large wheels for maneuvering over rough terrain.
The string trimmer line covers a much wider area than it does on a hand-held string trimmer. Overgrown lots and thick fields of weeds are no match for a wheeled string trimmer.
