that openers will not run any deeper than coulters
till the soil.
Press Wheel Adjustment
Refer to Figure 19
Changing the height of the press wheels automat-
ically changes seeding depth. To adjust, lift T-
handle and slide forward or back.
• For shallower seeding, slide handle ahead to-
ward implement.
• For deeper seeding, slide handle back away
from implement .
Opener Mounting Height
Refer to Figure 20
You also can lower individual opener bodies that
run in tire tracks. To lower an opener, move open-
er-pivot bolt to lower hole in opener mount.
Opener Down Pressure
Refer to Figure 21
To adjust down pressure on individual openers
that run in tire tracks, change opener-spring
length. To increase down pressure, loosen the
jam nut at lower end of opener spring, then turn
flange nut. Each 6 mm (1/4-inch) turn adds about
6 kg (13 pounds) of pressure. After adjusting
flange nut, tighten jam nut.
IMPORTANT: Do not turn flange nut more
than 25 mm (one inch). Turning flange nut
more than 25 mm (one inch) could cause
opener damage.
