What are cutting techniques using weed eater?

1. Screeding

For weeds that grows in paths, walkways, sidewalk cracks, and driveways, it is effective and fast to do with screeding. Do this by tipping the trimmer.

Make the string tips striking weeds at an angle rather than directly and with full force off the pavement. After that, move into the weed’s base, cutting them to the surface.

If angle the trimmer too shallow, then you are eating the string and ineffectively doing the cutting. If the angle is too sharp, the string can not hit enough of the weed’s base to cut evenly.

---

2. Scything

When you are up against an obstruction, you can not walk along or work in tall grass—bringing the trimmer into and out of work in a shallow U motion. By overlapping the scythes, techniques will even out the cut.

---

3. Edging

Where surfaces are parallel between grass and walkway or driveway, you can do the edging technique. Start by turning the trimmer, so the string is in a vertical position.

After that, walk the trimmer into the cut path so that it can eject or cut any material.

There could be rocks, debris, or dirt flying around. If the yards have never been edged, do not attempt to cut a crisp edge everything at once.

---

4. Tapering

Along a fence, retaining wall, tree, or curb tapering technique is very effective. This tapering means that you hold the trimmer, so the string strikes the grass at a slight angle.

Without tapering, the trimmer could cut shorter than the mowed grass. When you pitch the string tips toward the weed that you are trimming against, you are cutting less grass.

This trimming will also leave a tapered edge.
