Aim Headlights

1. Park tractor on level ground, with lights 8 m (25 ft) from a wall.

2. Measure from top of hood to the ground (A). Place a strip of masking tape (B) on the wall at the same height.

3. Place a piece of tape, folded in the middle to make a point, on the top front center of the hood.

4. Using the hood tape as a guide, sight across steering wheel and hood to locate tractor centerline. Mark tractor centerline (C) on wall.

5. From tractor centerline (C), mark a point 130 mm (5 in.) out in each direction (D). This mark locates a point directly in front of each headlight center.

6. Turn light switch to road lights position, then set headlight dimmer switch to low beam.

7. Locate small zone of bright light projected by each lamp. Cover other lamps if necessary. Top of zone (E) should be 130 mm (5 in.) below the tape. Left edge of zone (F) should be 130 mm (5 in.) left of lamp location marked (D).

8. Adjust as necessary.
