Opener Seeding Depth
Refer to Figure 18
A press wheel attached to each opener body con-
trols seeding depth. To maintain consistent depth,
the relationship between the bottom of the opener
disks and press wheel is fixed upwardly.
The press wheels also close the seed trench and
gently press soil over seed. To provide consistent
soil firming, press wheels are free to move down
from normal operating position. This maintains
pressing action even if opener disks encounter
obstructions or hard soil.
Refer to Figure 19
Set opener seeding depth by adjusting T-handles.
To adjust, first raise openers slightly, then lift and
slide T-handles on top of openers as shown. Ad-
just all T-handles to the same setting.
• For shallower seeding, slide T-handles for-
ward toward drill.
• For deeper seeding, slide T-handles back
away from drill.
