The design of a string trimmer Part 1

A string trimmer works by centrifugal force is turned on in this line is not fast enough to keep the shell from its (rotary) principle is very stiff. Facts have proved that the line tougher and faster. Even round section nylon line capable of cutting grass and mild, woody plants quite good. Designed for a more powerful tool. Some have a single thread extruded shape, like a star, helping the bank to cut the material being cut; this line it is possible to reduce a large woody plant (shrub), or at least very effective annular tree skin them. These lines make the disk painstaking work less necessary.

The production line is hand wrapped around a reel before the job starts, so that the two ends extending from the reel housing. Reel motor rotation, although operators swing where the plants are trimmed trimmer line extending horizontally. Operators control the cleavage occurs, and can be easily trimmed ground level height. As lines are worn or broken, the operator on the ground, knocking the reel so that the release mechanism allows to extend the number of line on the spool and replace the waste unit. Newer models have "Auto Input" operation in which the line, guard small cutter to ensure exposure does not exceed the length of the cutting line can effectively swing through the motor length. The new line extension to operate more efficiently, because of its heavy weight and surface effects. Spinning speed is usually the hub via a trigger on the handle to control.
