Garden Strimmers?

Question

whats the difference between a manual line feed and an automatic line feed on a petrol strimmer?

Answer 1

Not sure that petrol-powered matters all that much for this.  

An automatic line feed will use up your line more quickly, as it will spit out more line whenever it senses your cutting circle is too short, but it is less of a hassle to use.  Depends on how expensive and biodegradeable line is where you are, and how much that matters to you.

In some strimmers, putting in a new bobbin of line is a big hassle, and for those you might want to trade the minor inconvenience of having to tell the strimmer to spit out some more line manually (and having a smaller circle to cut with for awhile) for not having to do the replacement.

Answer 2

automatic feed lengthens as it breaks or wears down,with manual you have to do it yorself by manually pulling out the line.

Answer 3

automatic feed lengthens the cord as required. Manual you have to do it yourself
