ABSTRACT:
A debarking/delimbing apparatus having upper and lower flailing drums mounted crossway to a feed line for logs progressing through the apparatus. The upper flailing drum is pivotally mounted to enable movement of the flails toward and away from the feed line to accommodate different sized logs. A counter force urges raising of the upper drum but not sufficient to offset totally the gravity force. A gate across the inlet is connected to the upper drum mounting and when engaged by a log raises the upper drum in accordance with the diameter of the log. The length of the flails are only as long as needed to reach down to the mid-point of the largest size logs.
