PRESS WHEEL - OPENER LINKAGE DEPTH ADJUSTMENT

PLANTING DEPTH ADJUSTMENTS (CON’T.)

The depth of each opener is controlled by the height of the

wheel which automatically changes the seeding depth of

the opener, simply rotate the knob located directly above

each press wheel until the seeding depth is correct. A

self-locking spring clip holds the knob at your setting to

maintain the proper depth.

Each opener spring can be adjusted for down pressure.

This is useful when penetrating hard soil and for planting

in tractor tire tracks. To adjust the pressure, remove the

"W" clip at the bottom of the spring and place it in a higher

hole in the spring rod for more pressure, Fig. 21, and in a

lower hole for less pressure, Fig. 22. If too much penetra-

tion is achieved at the lowest pressure setting the "W"

clips may be completely removed.
