INDIVIDUAL OPENER SPRING PRESSURE SETTING
Each opener spring can be individually adjusted for down
pressure. This is useful when penetrating hard soil and
for seeding in tractor tire tracks. To adjust the pressure, remove the "w" clip at the bottom of the spring and place
it in a higher hole in the spring rod for more pressure or in
a lower hole for less pressure.
SEEDING IN TRACTOR TIRE TRACKS
When openers follow in tractor tire tracks and adjusting
the spring pressure on the openers does not give satisfac-
tory depth, Fig. 21, the opener lift arms at the top of the
spring rods can be turned over and bolted on the under-
side of the square lift shaft, Fig. 22. Be sure to adjust
spring pressure after making this change. WARNING: Ground clearance of these openers will be
reduced in transport.
