tractor. Locate the eight knock-outs as shown by the
arrows in the illustration above. Knock these out
carefully with a punch as shown in the inset above
and twist out.
On decks without knock-outs, position the baffle and
discharge plates as shown in Steps 4 through 6, then
drill ten 11/32” holes at each of the locations to attach
the baffle plates.
