Refer to Figure 115
a. Down pressure (shown at maximum)
b. Wheel stagger (shown staggered)

Press Wheel Down Pressure

sets down pressure, which may need adjust-
ment 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.

might try one row before re-configuring the entire planter.

“Lift Cylinder Lock-Up” on page 29.
