1. If the hydraulic system is not filled with oil it should be
purged of air before transporting and field operations.
Carefully hitch the Seeder to the tractor and connect
the hydraulic lift hoses.
2. Remove the Transport Locks. See Figure 3-8.
3. Check to make sure the tractor hydraulic reservoir is
full of the manufacturer's recommended oil.
4. Slowly raise the machine until all lift cylinders are
fully extended. Lower and raise the unit to verify that
all cylinders are working throughout the stroke. Fully
extend the lift cylinders and continue to hold the lever
until all cylinder rod movement stops. Raise/Lower
machine 5 times to purge air from the system.
5.
Do not loosen any hoses or fittings. Recheck tractor
reservoir to make sure it is within operating limits.
6. Re-install Transport Locks. See Figure 3-5.
Lift Circuit approximate oil requirement: .65 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.
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 3Pt 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 3-10.
F-1021-0719
WARNING
Figure 3-10: Air Manifold
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.
