To adjust the beam:
1. Figure 63. Position the tractor facing a
wall or screen, 2m (6ft) away.
2. Mark a point on the wall or screen by
sighting down the hood centre line.
3. Draw a vertical line (1) through the point.
4. Draw a horizontal line (2) through the
vertical line (1) at headlight height (4).
5. Mark two points (3) on the horizontal
line representing the distance between
the two headlights, spaced equally ei-
ther side of the vertical line (1).
6. Adjust each headlight individually by ob-
scuring the other, so that the points (3)
marked on the wall or screen are in the
centre of the beam. The centre of the
headlight beam may be found by mark-
ing the extremities of the beam both
vertically and horizontally, and dividing
by two.
