Marker Operation
Both markers can be raised simultaneously, but they only
can be lowered one at a time, alternating from one side to
the other.
If both markers are required down at the same time, run
one marker down, momentarily start to raise it, reverse the
hydraulic lever and lower the opposite marker. Holding the
lever down then will force both markers down.
On open-centers tractor where the oil flow cannot be con-
trolled, the rate of flow of oil from the tractor may be great-
er than the rate at which the marker cylinder can accept it.
The tractor hydraulic control lever will have to be held until
the cylinder reaches the end of its stroke.
Transporting
!
WARNING!
Towing the planter at high speeds can lead to loss of vehicle
control. Loss of vehicle control can lead to serious road acci-
dents, injury and death. Do not exceed 20 mph. To maintain
steering control, you may need to add ballast to the tractor front
end. To determine the amount of ballast required refer to your
tractor’s operator manual.
Before transporting the planter, check and practice the fol-
lowing items.
1. Check that planter is securely hitched to a sufficient
tractor. Refer to Tractor Requirements, “Specifica-
tions and Capacities,” page 38 and Attaching Plant-
ers to Tractor, “Preparation and Setup,” page 7.
2. Unload hoppers before transporting if at all possible.
The planter can be transported with full hoppers, but
the added weight will increase stopping distance and
decrease maneuverability.
3. Check that tires are properly inflated. Refer to Tire
Inflation Chart, “Appendix,” page 40.
4. Comply with all federal, state and local laws when
traveling on public roads.
5. Remember that the planter is wider than the tractor.
Allow safe clearance.
Parking
See also Storage, “Maintenance and Lubrication,”
page 31, for information on long-term storage.
1. Park planter on a level, solid area.
2. Lower planter to the ground.
3. Lower parking stands to the ground as shown in Fig-
ure 2-3. If ground is soft, place a board or plate under
stands to increase contact area. Pin (1) stands in low-
ered position.
