Opener Depth (Press Wheel Height)
A press wheel attached to each opener body controls
seeding depth. To maintain consistent depth, the
relationship between the bottom of the opener discs and
press wheel is fixed upwardly by an adjustable stop on
each opener.
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 discs encounter obstructions or hard soil.
Refer to Figure 32
Set opener seeding depth by adjusting press-wheel
height. To adjust, first raise drill slightly, then lift and slide
T-handles on top of openers.
• For shallower seeding, slide T-handles toward drill.
• For deeper seeding, slide T-handles away from drill.
