For work we have a couple Sthil brush cutters.
2005 FS 110 a older 1990 FS250
We use to cut back brush and grass around buildings (fire abaitment) and along a airport float plane harbor.
Lots of willow and alder, blueberry bushes, wild rose bushes and labridor tea, and a scrb type willow we just call buck brush, due to the tussok nature of the tundra and soft ground the wheel type string trimmers wont do.
We utilize the string trimmers and two types of steel blades.
The new tri wing type you sharpen with a flat file and the old style circular saw style that requires a round file and a heap of time to sharpen.
When cutting on inclines, ditches and water ways the handle bar type gives you some leverage when cutting sizeable brush.
The Sthil products have held up to some pretty heavy work over the years, given a new sparkplug or new gas line every 6 years.
I buy trimmer line on the 3 pound spool (square line) at each location I work (one less thing to throw in for the boat ride) 5 locations.
I keep a spare trimmer head just in case one has problems (48 mi from town by boat).
Any plant with a bark will make short work of your trimmer line.
Even the heavy stuff.
In the fall time the dry woody stalks of broad leaf plants (worm wood) are really hard on trimmer string line (snow drifting abaitment)
