This is Patrick Martin, who is about to fall this 200 year-old Beech tree in Darmstadt, Germany.
Patrick runs both Stihl and Husqvarna saws. In the photo he is shown with his Husky 266SE, which is fitted with a 50 centimeter long bar (18").
Patrick likes falling these big hardwood trees. This one measured 95 centimeters at the base (37") and the main log was 11.5 meters long (35').
Thanks, Patrick, for these interesting pics.
