No protruding nuts/bolts etc. on the front face to interfere with the opponent.
  7. No part of the bulldozer may protrude beyond the front of the pusher plate.
  8. Only Meccano parts may be used to construct the bulldozer, except for any additional weight used solely to make up to comply with Rule 3 and the label to comply with Rule 10.
  9. Each round of the competition starts with the pusher plates of the two bulldozers touching each other face to face directly over the starting line.
