Cord Tips
We ship three (3) thicknesses of Cutting Cord with your DR TRIMMER/MOWER.
The Cords are Blue (175-mil), Green (155-mil) and Orange (130-mil). Because conditions and vegetation
vary so much, you should experiment with Cord weights (diameters) to discover what works best for your
particular mowing and trimming situations. Here are a few things to keep in mind:
• If you buy Cutting Cord in rolls, cut it in 23" lengths.
•
Cord life depends on trimming conditions. Replace Cords when they become broken or frayed.
•
The smallest diameter Cord capable of cutting the material at hand combined with the fastest engine
speed usually provides the best grass trimming performance. When you need more power for thicker
growth such as berry canes, brambles, thistles, or ragweed, you may want to use the 155-mil or 175-mil
Cord in combination with the highest engine speed.
•
Ease the ends of the Cord into heavy growth and move slowly through thick growth. If there are woody
weeds in the material you are cutting, the cutting Cords may wrap around the stalks they cannot cut,
and pull away from the trimmer head.
•
Please note that installing more than two (2) Cords at a time does not improve trimming performance,
in fact, it can lessen it. Adding additional Cords creates drag on the Trimmer Head, robs the engine of
power, and may cause wrapping. Installing two (2) Cords, 180 degrees apart, is the best method for
optimal trimming performance.
•
When replacing Cords, do it one at a time and use the old Cord to mark the position for the new Cord
that you are replacing.
•
If the Cord breaks off flush at the Line Plate, use the new Cord to push out the old Cord.
•
Storing the Cord in a plastic bag with a damp sponge or cloth will help keep it pliable. You can also
soak your Cutting Cord in a bucket of room temperature water for a few days before use to make it
more pliable.
