Introduction
Introduction
Great Plains Manufacturing wants you to be satisfied with
any new machine delivered by the Great Plains Trucking
network. To ease the assembly task and produce a properly working machine, read this entire manual before assembling or setting up new equipment.
IMPORTANT: A crucial point of information about the
preceding topic. For safe and correct operation, read
and follow the directions provided before continuing.
Description of Unit
The 2S-2600 is a towed seeding implement. This two-section drill has a working width of 26 feet and folds to a transport width of 15 feet. The drill has straight-arm, doubledisk openers. The opener disks make a seed bed, and
seed tubes mounted between the disks place seed in the
furrow. Press wheels following the opener disks close the
furrow and gauge opener seeding depth. A T-handle on
the opener body is for seeding-depth adjustments. Seeding rates are adjustable with the seed-rate-adjustment
handle and the sprocket box.
The 2S-2600 features active hydraulic down pressure on
the opener frames. When used on a tractor with closedcenter hydraulics, constant down pressure ensures even
opener penetration in uneven ground. Hydraulic down
pressure is adjustable at a single point.
The 2S-2600F allows you to plant seed and apply fertilizer
in the same field pass. Dividers partition the drill boxesinto
seed and fertilizer compartments. The openers apply dry
fertilizer to the seed trench before the furrow is closed. You
also can use both compartments for seed.
Intended Usage
Use this implement to seed production-agriculture crops
in conventional-tillage applications.

Section 2 Setup
Section 2 Setup
This section covers drill preperation and setup. You must
hook the drill hydraulics to the tractor, bleed the drill hydraulics and make any necessary frame adjustments.
This section also includes instructions for folding and unfolding the drill. Read these instructions carefully before
folding or unfolding the drill.
Tractor Hookup
!
DANGER!
You may be severely injured or killed by being crushed between
the tractor and drill. Do not stand or place any part of your
body between drill and moving tractor. Stop tractor engine and
set park brake before installing the hitch pin.
!
WARNING!
This drill can have positive and negative tongue weight, which
can work the hitch pin loose during transport. To avoid serious
injury or death due to a road accident, always use a clevis hitch
or clevis drawbar with a locking-style hitch pin.
1. Use a locking-style hitch pin that is sized to match the
holes in the hitch and drawbar. Hitch drill to tractor
drawbar.
2. Securely attach safety chain to an anchor on tractor
capable of pulling drill.
3. Store jack on storage tube on top of tongue as shown
in Figure 2-1.
Hydraulic Hose Hookup
!
WARNING!
Escaping fluid under pressure can penetrate the skin causing
serious injury. Avoid the hazard by relieving pressure before
disconnecting hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result.
Great Plains hydraulic hoses are color coded to help you
hookup hoses to your tractor outlets. Hoses that go to the
same remote valve are marked with the same color.

Section 2 Setup
Great Plains Mfg., Inc.
1. Connect opener-lift hoses to circuit designated for hy-
draulic-motor control.
2. Connect transport-lift hoses to tractor remote valve.
3. Connect fold hoses to tractor remote valve.
NOTE: If your tractor has only two remote valves, you must
install a double-selector valve to combine the transport-lift
and opener-lift circuits. Refer to Two Outlet Hydraulic Kit,
“Options,” in the operator’s manual.
Bleeding the Hydraulics
To function properly, the hydraulics must be free of air. If
hydraulics are not bled, they will operate with jerky, uneven
motions and could cause wings to drop rapidly during folding or unfolding. Complete the following procedures during initial drill setup.
!
WARNING!
Rasing the openers on the unfolded, unhitched drill will cause
the drill tongue to rise suddenly, which could cause serious injury or death. Be certain that the drill is hitched securely to your
tractor drawbar and the safety chain is securely attached to the
tractor before raising the openers and unfolding the drill.
!
WARNING!
Escaping fluid under pressure can penetrate the skin causing
serious injury. Avoid the hazard by relieving pressure be-
fore disconnecting hydraulic lines. Use a piece of pa-
per or cardboard, NOT BODY PARTS, to check
for suspected leaks. Wear protective gloves
and safety glasses or goggles when working with hydraulic systems. If an accident
occurs, see a doctor immediately. Any fluid injected into the skin must be surgical-
ly removed within a few hours or
gangrene
could result.
Bleeding Opener Lift Hydraulics
Refer to Figure 2-3.
1. Check hydraulic fluid level intractor reservoir and fill to
proper level. Add fluid to system as needed. System
capacity for entire drill is about 4 1/2 gallons.
2. Make sure opener frames are locked up in road position. Refer to Opener Lock Up,“Operation Instruc-
tions,” in the operator’s manual.
3. Turn knob on both pressure-control valves (1) completely counterclockwise, then turn valves clockwise
far enough to build up 1000 psi (about three turns).
4. Turn knob on bypass valve (2) completely clockwise
for no oil flow.
5. Loosen hose-end fittings (3) at the locations shown in
Figure 2-3.
NOTE: Do not loosen an O-ring fitting for bleeding. Bleeding air from an O-ring fitting will damage the seal.
6. Slowly supply oil to top side of pressure-control valves
until oil begins to appear at a loosened hose fitting. As
oil begins to appear at a fitting, tighten that fitting.
7. Slowly supply oil to bottom side of pressure-control
valves until oil begins to appearat remaining loosened
hose fitting. As oil begins to appear at the fitting, tighten fitting. Continue to supply oil to bottom side of pressure-control valves until all openers are raised
completely.
