ers and hex nuts (3). Slide mount forward so its leading edge
is about 3 15/16 inches ahead of front edge of drill frame
tube.
2. Bolt transport carrier (4) to transport-carrier mount so top
surface of saddle (5) is about 35 3/8 inches above top of drill
frame tube. Secure transport carrier with 1/2-by-2-by-3-inch
u-bolts (6), lock washers and hex nuts (7).
