Planting Depth Adjustments
1.
Soil Conditions -
Changes in field conditions
can require changes to several of the
adjustments below.
2.
Row Unit Opener Depth
(page 65) - The
T-handle directly controls opener depth by setting
the press wheel height.
3.
Tool Bar Height
(page 57) - Spacers at the
center section (master) lift cylinders control the
center section tool bar height when the
implement is lowered.
Wings must also be level (page 59) for this
adjustment to accurately set wing gauge wheel
height.
In some conditions, increased cart weight
transfer (page 58) may be required to prevent
openers from lifting the tool bar.
4.
Wing Weight Transfer
(page 58) - If the wings
are not operating at desired planting depth, more
center section weight may need to be transferred
to wings.
5.
Coulter Depth
(page 62) - Coulters prepare the
furrow ahead of the openers. If coulters are
running too shallow or too deep, the openers may
not operate at the desired depth.
6.
Row Unit Spring Adjustment
(page 63) -
Several rows in tire tracks may need to be set to
higher down-force in certain conditions.
7.
Opener Wear
(page 64) - Over time, opener disk
wear can cause T-handle settings to become too
shallow.
Adjusting Tool Bar Height
See “” on page 23 for how to check tool bar height.
To change the tool bar height, add or remove master
lift cylinder rod spacers (1), see “
” chart on the following page.
To change spacers:
1. Lift the drill (page 32).
2. Add or remove spacers. Unused spacers are
stored on rod loops on the cart-implement link. If
you store spacers on hoses, make sure they
cannot slide into locations where they interfere
with implement operation.
The cylinder has 5.7 cm of exposed rod when
fully retracted, for a minimum tool bar height of
58.4 cm. All spacer combinations that increase
tool bar height above the minimum must be a
stack of at least 5.7 cm in height.
Each full centimeter of spacer stack height
modification changes the tool bar height by 2 cm.
Do not use a spacer stack taller than 10.2 cm, or
the furrow will be too shallow, or there will be no
furrow at all.
Chart values are approximate. Press wheel
settings, disk wear, and manufacturing
tolerances can cause actual heights and
depths to vary from chart values. Choose
spacer combinations based on actual field
measurements.
