Press Wheel Stagger
Refer to Figure 94
Press wheel assemblies other than “cast, adjustable”
have two threaded holes in the mount
for the wheel
bolt .
Note: Although staggered press wheel assemblies use
the same weldment as angle-adjustable
assemblies (below), the two hole staggered
mount
is always used at adjustment bolt hole “2”.
It cannot be moved to “1” or “3”.
The factory stagger setting has been found optimal for
residue flow. If your conditions appear to require even
press wheels, you might try one row before reconfiguring
the entire planter. To change the stagger:
1. Raise the planter and install the lift cylinder locks.
See “Install Lock Channels” on page 31 and
“Frame Lift Cylinder Locks” on page 102.
2. Remove the bolt , spacers , and lock-washer
for the left press wheel .
3. Move the wheel to the alternate of the two mounting
holes.
4. Re-install the bolt, lock washer and spacers. Tighten.
Press Wheel Angle
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 95
1.
Raise planter and install lift assist cylinder locks. See
“Install Lock Channels” on page 31 and “Frame
Lift Cylinder Locks” on page 102.
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
inch (19 mm) 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
available. Consult your Great Plains dealer.
