I'm surprised the PDS didn't go off! (to borrow somebody's acronym from the old forum. Pinecone Detection System.) I believe the system was designed to go off whenever the sled got within 100 feet of a pinecone. All the device did was simply cause the crank to break in half, thereby rendering pinecone related damage impossible.
