Arnold Trimmer Line

This is a universal trimmer line designed to fit most gas-powered string trimmers. However, because it has a thicker diameter of 0.155 inches, you should verify that your specific trimmer head is rated to accept line of this size before purchasing.

The twisted shape creates a more aerodynamic profile that reduces vibration and noise while cutting. It also provides sharper edges that slice through dense brush and thick weeds more efficiently than a traditional smooth, round line.

Yes, this product is specifically engineered for walk-behind trimmer mowers. It even includes a dedicated cutting tool to help you trim the line to the correct length for your machine.

With a 0.155-inch diameter, this is a heavy-duty line intended for clearing thick weeds, tall grass, and dense brush. It may be overkill for simple lawn edging or light grass maintenance.

This universal line is compatible with major brands including Troy-Bilt, Ariens, MTD, Swisher, and Poulan. As long as your trimmer head supports 0.155-inch diameter line, it should work effectively regardless of the brand.
