Independent professional logger, 20 years experience. Operates in Auvergne (Massif Central) — mixed taillis, dead wood, abrasive conditions (sandy soil, granite dust). Saw: Husqvarna 572XP with a 20" bar (3/8" pitch, .050" gauge, 72 drive links). Cuts 6-8 hours per day, sharpens 2-3 times per session. Currently runs Stihl Rapid Super; replaces chains every ~30 cutting hours due to wear. Skeptical about brand-switching after 12 years on Stihl.
