How does a grass trimmer work?

Garden trimmers have a line of nylon cord, which clips into the trimmer head and is spun at very high speed. As the cord spins it cuts through grass or other vegetation. Some models require you to change the cord when it wears out, or breaks by hitting a hard object such as a stone, but others have an integral cord spool which feeds through automatically as required and will only need replacing when the spool runs out.

Some models are fitted with a double cord, which provides higher performance for areas of the garden which are particularly overgrown. If you need a trimmer to keep your lawn edges looking perfect, choose a model with a rotating head. Then simply rotate to 180 degrees, which provides the right angle for the lawn edges.

Not only will your lawn edges be the envy of the neighbourhood, but your back will benefit too because you won't have to kneel down to cut the edges by hand. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
