While skidding on a block, a stick got caught (2-3" in diameter and several feet long) in the tire chains on the skidder.
The stick was small enough that it passed through the protective grating on the side window on the door of the skidder. The inside window on the skidder door was slid open.
The stick entered the cab about 12" startling the operator.
