The planter should never be transported faster than
20 miles per hour
!
Before transporting the planter, check and practice the
following items:
•
The planter can be transported with full boxes of seed.
It is best NOT to because the extra weight increases
the chances for problems on the road. Do not exceed
20 miles per hour.
•
Check to see that the gauge tires on the planter have
the proper inflation as listed in the Tire Inflation Chart
in "Section 9 Specifications" on page 28.
•
Comply with all Federal, State and Local Safety Laws
when traveling on public roads.
•
Remember, the planter is wider than the tractor and
extreme care must be taken to allow for safe clear-

Leveling the Planter
The planter must be level for the row units to function
correctly. Before leveling the planter check tire pres-
sures as specified in the Tire Inflation Chart in “Section
9 Specifications” on page 33.

side to side. It is best to adjust the links evenly before the

the field, stop the tractor on flat ground with the planter
lowered. Check the front-to-back level of the planter.
The bottom of the frame tube should be parallel to the
ground. If this is not parallel, adjust the upper link on the
tractor accordingly.
If the row unit arms are not parallel to the ground, the
gauge wheel modules must be adjusted equally. Mea-
sure the vertical distance between the front pivot and
rear pivot of a row unit arm, see Figure 2-3. This is the
amount that the gauge wheel needs to be adjusted.
Raise the planter and loosen the jam nut (A) on the
wheel module. To lower the planter, turn the nut (B) at
the opposite end of the link counter-clockwise and clock-
wise to raise the planter, see Figure 2-2. Tighten the jam
nut after reaching the desired wheel location.

WARNING!
Never work under the planter while in the raised position.
