1. Carefully hitch the Seeder to the tractor and connect
the Hydraulic Lift Hoses.
2. Check to make sure the tractor hydraulic reservoir is
full of the manufacturer's recommended oil.
3. If the Transport Locks are engaged, raise the Seeder
and remove the Transport Locks. See Figure 3-6.
4. Slowly raise the Seeder until both Lift Cylinders are
fully extended. Lower and raise the Seeder to verify
that both Cylinders are working throughout the stroke.
Fully extend the Lift Cylinders and continue to hold
the lever until both Cylinder Rods movement stops.
Raise/Lower Seeder 5 times to purge air from the
system.
5. Do not loosen any Hydraulic Hoses or Fittings.
6. Recheck tractor reservoir to make sure it is within
operating limits.
7. Raise the Seeder and install Transport Locks. See
Figure 3-5.
Lift Circuit approximate oil requirement: .81 gallons.
Rear Roller Air System
IMPORTANT
Do not at any time operate the Rear Roller Air System
Air Pressure below 15psi. The Air Springs must
maintain a minimum Air Pressure for proper inflation.
Too low of pressure will cause the Air Springs to rub
internally and lead to failure.
WARNING
Relieve Air System Pressure before attempting to
adjust or service Air Springs and Air Lines. Wear
protective gloves and safety glasses or goggles
when working with Air System. High pressure air
can propel debris at high speed, causing eye
injury or blindness. If you are injured, obtain
medical aid immediately.
IMPORTANT
Do not pressurize the Rear Roller Air System unless
all related components are installed.
Each Rear Roller Arm has an Air Spring to increase
down force on the Rear Roller which improves seed to
soil contact.
•
Air Pressure adjustments are made at the Air
Manifold on either the 3-PT Hitch or Drawbar. The
Manifold Schrader Valve allows Air Pressure to be
increased from an external source such as shop air or
allows Air Pressure to be decreased by releasing air
from the system. To relieve all System Air Pressure,
pull Relief Valve Pull-Ring. See Figure 3-8.

Pressure Gauge
•
The Rear Roller Air System can safely operate in a
range from 15psi to 100psi.
Recommended Air System Pressure is 90psi.
Do not exceed 100psi System Pressure which is the
maximum recommended working pressure the Air
Springs are rated for. Air Springs maximum jounce
pressure rating is 200psi. A Relief Valve in the
Manifold protects the Air System from excessive
pressure.
•
Do not remove or adjust the Relief Valve or damage
to the Air System may occur. The system is
maintenance free. Reduce Air Pressure to 15psi if
stored for an extended period of time.
