00 & 00HD Series Opener Depth
Press Wheel Adjustment
A press wheel is attached to each opener body. Press
wheels provide two important functions.
First, press wheels close seed furrows and gently press
soil over seed. To provide consistent seed 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.
Second, press wheels control seeding depth. To
maintain a consistent depth, the relationship between the
bottom of the opener disks and press wheel is fixed
upwardly by an adjustable stop on each opener. The
position of the adjustable stop determines how deep
seed is placed. Raising the stop increases seeding
depth. Lowering the stop decreases seeding depth.
Refer to Figure 55
Set opener seeding depth by adjusting press-wheel
height. To adjust, first raise openers slightly, then lift and
slide T-handles on top of openers. Adjust all press
wheels to the same height.
• For shallower seeding, slide T-handles toward drill.
• For deeper seeding, slide T-handles away from drill.
Note: Opener down pressure controls soil-firming
pressure on press wheel. Use press-wheel
adjustments to regulate seeding depth and
opener-down-pressure adjustments to control
opener penetration and soil firming.
