Opener Press Wheel Depth

Refer to Figure 4-12:

The depth of each opener can be adjusted by the posi-

tion of the press wheel, Figure 4-12. After setting the

coulters to the desired depth by using the depth control

on the end wheel cylinder, see page 22, you can now ad-

just your press wheels up or down to achieve the correct

seeding depth.

With the drill level and lowered to planting position, ad-

just the knob and adjustment trunnion located above

each press wheel. This will vary the height of the press

wheel which automatically changes the seeding depth of

the opener. Simply rotate the knob until the seeding

depth is correct.
