OPERATION
Hydraulic Lift System
The 4620-24 Folding Seeder is equipped with a
Hydraulic Lift System to raise and lower the unit from
transport to planting position.
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 and locate Locks to
Storage Position. See Figure 3-7.
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 3-8.
Lift Circuit Hydraulic Fluid approximate requirement:
Machine Raised = 2.3 gallons
Machine Lowered = 2.0 gallons

DANGER
DANGER
The Folding Seeder should be folded/unfolded on
a large level area large enough to accommodate
the seeder when unfolded. Be sure other people
and pets are a safe distance away. Tractor should
be stopped and not moving, with the engine at a
slow idle.
DANGER
DANGER
Keep all bystanders away from the machine when
folding/unfolding or transporting.
The 4620-24 Folding Seeder is equipped with hydraulic
cylinders to fold and unfold the seeder from transport to
field position. A combination of the Fold, Lift and Wing
Lock Hydraulics will be used to fold/unfold the seeder.
Before unfolding/folding the seeder, be sure the seeder is
properly hitched to the tractor. See "Attaching Folding
Seeder to the Tractor" on page 3-2.

TABLE OF CONTENTS
UnFolding:
1. Fully raise the Seeder to relieve pressure off the
Transport Locks. Remove Transport Locks and
relocate to storage position. See Figures 3-7 and 3-8.
2. Activate Wing Fold Circuit. Continue to unfold the
seeder until the 4 x 20 Hydraulic Fold Cylinders have
fully extended.
3. Activate the Wing Lock Circuit (Auxiliary) retracting
the 3-1/2 x 6 Slide Lock Cylinder and extending the
two 2 x 3 Contour Lock Cylinders on each wing. Slide
Lock Hooks should be engaged on each side of the
Frame Tube and each wing will now move fore-aft
and laterally. See Figures 3-4 and 3-5.
4. Lower Seeder with 3-PT Hitch and Seeder Hydraulic
Lift to begin seeding.
Folding:
1. Raise seeder completely with Seeder Hydraulic Lift
and tractor 3-PT Hitch.
2. Activate the Wing Lock Circuit (Auxiliary) extending the
3-1/2 x 6 Slide Lock Cylinder completely and retracting
the two 2 x 3 cylinders on each wing. Seeder wings
should now be locked to prevent fore-aft and lateral
movement. See Figures 3-4 and 3-6.
3. Activate the Wing Fold Circuit. Fold the wings forward
completely
4. Install Transport Locks over Lift Cylinder Rods and
secure with bent pins and hair pin cotters. See
Figure 3-8.
