Lawn & Garden Fast Facts, Last Updated:09/09/2010 The line is hand-wound onto a reel before the job isstarted—leaving both ends extending from the reel-housing.The reel is turned by the motor and the line extends horizontallywhile the operator swings the trimmer about where the plants are tobe trimmed. The operator controls the height that cutting takesplace and can trim down to ground level quite easily. As the lineis worn, or breaks off, the operator knocks the reel on the groundso that a release mechanism allows some of the line in the reel toextend and replace the spent portion. A small cutter on theline-guard ensures that the line length exposed for cutting does noexceed the length that can be swung efficiently by the motor. Newlyextended line operates more efficiently because of its heavierweight and surface effects (the star-shaped edges). |
