[Brushcutter] Need trimmer head for big cords

Good morning from France

I need a new trimmer head for a Honda 435 UMK-E (four-stroke)
brushcutter. My favorite cord size is 3mm. I can look that up in
inches but do not really want to. Let's say big cords, the bigger
the better.

The problem is not that I do not find any.

The problem is that I *have* found some and none are really a
replacement for the original trimmer head that came with the machine
and lasted 9 years.

The first replacement virtually exploded on second use and I have
not located all parts yet.

The next was advertised for cords of *up to* 3mm but was unable to
cope with them.

My current trimmer head *does work*, but after a few minutes in
a real thicket, the cord is seized in its furrow and would not sort,
when I need to extend it anew.

I have a few guesses.

An advertised cord size of 3mm means *round* cords, most of the
time, while my own are square and more efficient this way, while
relatively inexpensive.

The Honda trimmer head was good for everything, while its diameter
was not above 10cm (most big trimmer heads are 13cm). While the
machine is powerful enough, recommendations may be given for smaller
heads, which resemble the original. In consequence, if I cannot find
a Honda reseller (a bit difficult in our region) I must know which
*other* brands would be possible.

Now. Your *experience* may be more interesting and more important
than an actual recommendation. However, if you happen to be in a
comparable situation, you might have a trimmer head in mind …

That would be cool.

Cheerio
