SECTION 7 – OPERATION - ALL MACHINES
TRANSPORT TO FIELD POSITION
To place machine in field position from transport position,
follow this procedure:
1.
Hitch machine to tractor drawbar using a locking hitch
pin. Connection hydraulic hoses to tractor. Raise jack(s).
2. Select a level area in the field in which to open the ma-
chine.
3. IMPORTANT: Remove the transport locking pins if
they are in the lock position (See Fig. 30). Store pins
in the storage holes provided.
4. Back machine up slowly, maneuvering it so wings
open evenly. If wings do not open evenly, pull ahead
and try again. Open wings until they are slightly
ahead of the center.
5. Machines without Auto-Fold: Attach cables.
20’ hitch with Auto-Fold only: Retract Auto-Fold cyl-
inder (See decal 8Z0093 on page 1-3 for further in-
formation).
6. Extend the hydraulic cylinders located at rear of hitch
and lower the sections in a smooth continuous mo-
tion until the sections are resting on the ground.
When lowering machine to field position, a hydrau-
lic restrictor valve prevents the machine from “fall-
ing” too fast. Once the machine is resting on the
ground, it may be necessary to hold the hydraulic
control lever several seconds to allow oil to com-
pletely fill the cylinders and extend their full stroke.
7. Hinge wing machines only: The 1-1/4” x 9-1/2” lock
pins must be removed before field operation. Store
pins in storage holes provided.
FIELD TO TRANSPORT POSITION
To place machine in transport position from field position,
follow this procedure:
1.
Stop in a level area and back tractor up enough to pro-
vide slack in the pull cables. (20’ hitch with Auto-Fold
only – extend Auto-Fold lock cylinder.)
2. Hinged wing machines only: The 1-1/4” x 9-1/2” lock pins
must be installed before placing the machine into trans-
port position.
3. Raise the sections by completely retracting the hydrau-
lic cylinders located at rear of hitch.
4. Machines without Auto-Fold: Detach cables and secure
out of the way (draping over sections provide an easy
way of storing cables).
5. With the machine resting on its transport wheels, drive
the tractor forward. The wings should fold to trailing
(transport) position. NOTE: If the wings do not trail prop-
erly, transport wheel “toe in” may need to be adjusted
(See Fig. 32).
6. Install Transport Lock Pins.
UNHITCHING MACHINE
1.
Always select a level area in which to park machine. As
an added precaution, block the wheels on the hitch to
prevent the machine from rolling.
2. Insure that Transport Lock Pins are installed (See Fig.
30).
3. If hitch tongue is light, mount hitch jacks on wing tube
before tractor is removed. (See Fig. 31 and Page 1-2 –
Negative Hitch Weight Warning). Two wing tube jack
brackets are standard on all Superweeders. The sec-
ond wing tube jack bracket is optional on most Culti-
Harrows and Superharrows. Order PN 8C2280 for
bracket and PN 8D0330 for mounting U-bolt.
CAUTION! ALWAYS BLOCK UP THE
HITCH WHEN UNHOOKING A MACHINE
WITH MORE THAN 100 GALLONS RE-
MAINING IN THE SPRAYER TANK. HITCH
JACK WILL NOT SUPPORT MORE THAN
THIS WEIGHT.
4. After completing above steps, disconnect hydraulic
hoses, remove hitch pin, and drive tractor carefully
ahead.
CULTI-HARROW ADJUSTMENTS
LIFT ARM ADJUSTMENT
Once the Culti-Harrow is in field position, the lift arms can be
adjusted hydraulically. Lift arms should be parallel with the
ground. If the harrow is equipped with optional spring pres-
sure, the lift arms can be adjusted lower on the rear to put
spring pressure down on the sections. IMPORTANT: The
harrow lift arms should never ride on the harrow sections as
this will damage the lift arms and sections.
