Opener Depth
10HDP Opener Depth
Seeding depth on 10HDP Series is set by row unit depth.
Set frame height (page 21) before making row unit depth
adjustments.
10HD Series press wheel height is a stop adjustment
and not a spring adjustment. It establishes a fixed rela-
tionship between opener depth and the closed-furrow
surface at the press wheel
Refer to Figure 63
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. Initially adjust
all press wheels to the same height. Individual rows run-
ning in tire tracks may need to be set deeper
a
.
• For more shallow seeding, slide T handles forward
toward YP30 planter.
• For deeper seeding, slide T handles backward
away from YP30 planter.
If press wheels are lifting off ground, check front-to-back
level, and increase row unit spring down force.
If press wheels are digging into ground, reduce spring
down force at the row units.
20P Opener Depth
Refer to Figure 64
Side depth wheels
at the row-unit disks control
row-unit planting depth. The position of an adjustable
stop, using the T-handle
, determines planting depth.
With the planter raised, lift the side depth wheel against
the stop and measure the depth of exposed opener disk
below it.
Set planting depth by adjusting handle . To adjust, first
raise row-units slightly, then lift and slide handle on top of
row-units. Adjust all handles to the same setting.
For shallower planting, slide handle forward toward
planter.
For deeper planting, slide handle back away from
planter.
Check opener down-pressure and press wheel(s) after
adjusting depth. See “20P Series Down-Pressure” on
page 64 and “Press Wheel Adjustment” on page 83.
