Leveling the Planter
During initial setup and periodically throughout the plant-
ing season, check that the planting units are running level.
When planting, the top of the hopper support panel (1)
should be parallel to the ground as shown in Figure 1-4.
To level the planter, the bottom of the main frame tube
must run between 20 and 22 inches above ground when
lowered into planting position. See Figure 1-4.
To obtain the correct height, reposition the planter hitch on
the tongue. Proper tongue adjustment improves seed
placement by allowing the row units to operate parallel to
the ground.
The mounting holes in the hitch have been offset so the
hitch can be turned over and bolted on in four positions,
giving eight possible hitching positions. Use the screw jack
to raise the front of the planter tongue. Adjust the planter
hitch to match your tractor drawbar. See Figure 1-5.
IMPORTANT: When hitching the planter to a different
tractor, check for a difference in drawbar heights. If
the heights are different, re-adjust height accordingly.
Achieving correct planter position can be difficult with
some attachment combinations, especially when planting
in hard to penetrate soils. Avoid using more attachment
down force than is required.
