The rake (5) has tooth carriers (6A, 6B) with outer portions, respectively, where each outer portion extends along a longitudinal axis. Rake teeth (7, 8) comprise three different groups of legs. Leg end lines of the different groups of legs respectively exhibit polar angles with respect to a polar axis running through the longitudinal axis of the outer portions of the tooth carriers, in a view direction corresponding to the longitudinal direction of the outer portions of the tooth carriers. The polar angles are different from each other. |
