And take all safety precautions. Okay. So now I'm going to take the battery.

String trimmers are used to trim the grass in tight spots that a lawn mower can't reach, like along a fence, under decks or near delicate plants and shrubs. On the other hand, lawn edgers are used to clean up borders along sidewalks and driveways.

Some cordless string trimmer models have two-in-one capability, meaning you can use them for multiple purposes. If you need to trim areas that your mower can't reach, or you want to be especially careful around your ornamental plants, you can use your two-in-one tool as a string trimmer.

The clipper is moved so that hair is positioned between the teeth of the comb, and cut with a scissor action when one blade slides sideways relative to the other. Friction between the blades needs to be as low as possible, which is attained by choice of material and finish, and frequent lubrication.

The trimmer mechanism includes two sets of blades that are moveable relative to each other to define a pair of cutting zones. One set of blades provides a coarse trim, while the following set of blades provides a finer trim. Also provides is a blade arrangement and a method of manufacture of a blade arrangement.

A strimmer is the same as a grass trimmer but is the colloquial term for the tool. This garden appliance is handheld and uses a nylon line as a plastic blade to cut grass and trim around the edges of the lawn. A strimmer is not the same as a hedge trimmer which is more of a saw for trees and hedges.

This battery is built to last and be charged again and again. 3 amp hours of runtime per charge means you can keep working, with none of the dreaded “memory effect” that drained older batteries. When fully charged it holds its charge for up to 18 months, or 500 days, so it's always ready whenever you need it.

The run time of the trimmer is 10-15 minutes per battery on a fully charged battery. Battery run time may vary depending upon factors including but not limited to charging conditions, battery maintenance, storage and environmental conditions.

The two main types of string trimmers are gas-powered and electric. Gas string trimmers are cordless, powerful, have two-cycle engines and require a mix of gas and oil to operate. These are often considered the best string trimmers for grass. They work especially well for large lawns.

A string trimmer, also known by the portmanteau strimmer and the trademarks Weedwacker, Weed Eater and Whipper Snipper, is a garden tool for cutting grass, small weeds, and groundcover.
