Eternal metal trimmer heads

Most grass trimmers are factory fitted with semi-automatic line release heads. I pressed the head with the engine running - the line came out of the bobbin for some length and you can mow further. Convenient, but due to the plastic body of the coil, breakdowns occur:

In my case, the case broke off. Either the plastic is fragile, or something got into the slot in the lid attachment points.

Which trimmer head did you buy - article here: New type of trimmer reel: with manual line release. I explain why it is better than a semi-automatic

If you no longer want to mess with plastic spools, we wind the fishing line awkwardly into the bobbin (although some models have a different the principle of winding the line - without removing the cover, without removing the bobbin) - then your option is a completely metal head with mechanical fixation fishing line:

Even such uncommon models exist in several varieties. But the principle of fixing the fishing line is approximately the same: insert the fishing line (crosswise) into the holes in the aluminum body and tighten it with a bolt (or bolts under each exit).

Sometimes, with a small diameter of the fishing line, two pieces are inserted. According to reviews, such a trimmer head mows the grass very effectively. But for low-power electric trimmers it may not be suitable due to the high resistance of the grass (a lot of lines - more friction against the grass).

Prices and some assortment:

An overview of such a reel, the principle of attachment and installation of the fishing line, is shown in the video:

There are other types of metal trimmer heads. The next example is a spider head:

Indeed, it looks like a spider with many legs. The line is not bolted in this head. It is fixed by its bend.

Despite the fact that there is nothing to break in these trimmer heads, they have disadvantages. When grinding the fishing line (reducing its length in the process of work), the efficiency of the process also decreases. Less grass is cut in one pass with the trimmer. The line will have to be changed quite often, there will be a lot of scraps. Those. line consumption in such a reel can be even higher than in the classic version with a spool.

You also need to constantly carry a hex key with you to change the fishing line. The replacement process is not that fast.

There is another option for a metal head for a trimmer with an eternal line - a head with a chain like a chainsaw:

Many offers on aliexpress. But Russian online stores also offer:

Prices from 630 rubles.

It is, indeed, an eternal head with an eternal line. According to reviews, it is suitable for mowing thick grass, thin shrubs. On ordinary grass, its speed is low. The line head can handle normal grass faster. And, this is, so to speak, a universal option without consumables in the form of a fishing line.

Who will use - be careful! You need to mow in boots, better in tarpaulin. Because the chain is especially likely to get into trouble.
