Title: Arrangement for mounting a cutting head assembly of a delimbing device on a support member

Abstract: A delimbing device includes a cutting head assembly having (i) a cutting blade configured to cut branches off of a tree and (ii) a bar saw configured to cut through the tree. The device also includes a first support member supporting the cutting head assembly. The device further includes a second support member supporting the cutting head assembly. The device also includes a bearing assembly secured to the first support member and the second support member so that (i) the bearing assembly is interposed between the first support member and the second support member and (ii) the cutting head assembly can rotate relative to the second support member around an axis of rotation such that when a rotational force is applied to the cutting head assembly the cutting head assembly rotates from a first orientation to a second orientation. The bearing assembly is configured so that when the rotational force is removed from the cutting head assembly the cutting head assembly spontaneously returns to the first orientation from the second orientation.
