Press Wheel Centering
If one press wheel is running in the seed trench, or the
wheels are not centered over the trench, the angle
of
the press wheel assembly can be adjusted as follows:
Refer to Figure 57
1.
Determine how far, and in which direction, the press
wheel assembly needs to move to center the wheels.
2. Raise drill.
3. Loosen the
1 ⁄
2 in hex-head bolts and .
Note: Do not loosen the square-head bolts forward of the
hex-head bolts.
4. Turn the hex head cam under the forward hex
head jam bolt , and move the required amount.
5. Tighten both hex head bolts .
Press Wheel Assembly with Cast Wheels
Tight soil may require the need to drag/plow the trench
closed. The factory setting on press wheel assemblies
with cast wheels is 4˚(maximum plow). If the conditions
in your region appear to require less plow, there are two
additional settings: 2˚ (less plow) and 0˚ (no plow). To
change the plow setting:
Refer to Figure 58
1.
Raise drill.
2. Remove the bolt , lock-washer and spacers
for the press wheel .
3. Remove bolt , flat washer and hex nut for
casting .
4. Place a
3 ⁄
4
in open end wrench on tab of casting.
Rotate casting until the desired angle setting (4˚, 2˚
or 0˚) hole lines up with a hole on the press wheel
mount weldment
(only one set of holes will line up
for each setting).
5. With holes lined up replace casting bolt and flat
washer . Secure with hex nut .
6. Reinstall press wheel.
If press wheel adjustments do not provide satisfactory
furrow closing, your conditions may require alternate
press wheels. A variety of wheel assemblies are avail-
able. Consult your Great Plains dealer.
