Dual Line Trimmer Head Why Aluminum Lasts Longer

With a trimmer, the part that gives up first is usually not the engine, it is the head that snaps its line as it spins. The trimmer head is a wear item by nature: two nylon lines whirling at high speed, working against grass, vines and the odd stone, and it is the first thing to be used up.

Why is this one made of aluminum? Cheap heads are often all plastic, and the shell cracks after one solid hit, then the warped spool feeds line unevenly. This one uses an aluminum spool: the aluminum body takes the knocks without warping, turns true, and holds together through long high speed work instead of loosening and cracking, outlasting an all plastic head.

What does two line mean? Both lines cut at the same time, so the strip is wider than a single line, covering more in one pass. The two lines come pre fitted, so the head clips onto the machine and is ready to run with no threading.

What about a broken line? Thread the trimmer line back into the spool channel and press it home. Leave a little slack when threading, not pulled tight, and the feed runs smooth. When fitting new lines, choose a thickness that matches your machine and do not overdo it. Line that is too thick will not let the spool feed and will tangle and skip.
