Press Wheel Down Pressure
Handle
sets down pressure, which may need
adjustment for different soil types and field conditions.
• Relax the handle forward (in the direction of travel) for
decreased down pressure.
• Pull the handle back for increased down pressure.
Note: Higher press wheel down pressures reduce the
down force on the main row unit shank
components, such as the openers. High press
wheel settings may require an increase in overall
row unit down force. See page 46.
Press Wheel Stagger
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 “Lift Cylinder Lock-Up” on page 62.
2. Remove the bolt , spacer , nut (not shown) and
lock-washer (not shown) for the left press wheel .
3. Move the spacer and wheel to the forward of
the two mounting holes at .
4. Re-install the bolt, lock washer and nut. Tighten.

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”.
