BD7600-26 Table of Contents Index Introduction
Introduction
The BD7600-26 Drill is a towed seeding/fertilizing
implement. This two section min-till drill has a
working width of 26 feet (7.9 m) and folds to a width of
16 feet (4.9 m) for transport.
The seed metering system is ground drive or
hydraulic drive.
Intended Use Statement
The BD7600-26 Drill with standard equipment and/or
authorized attachments and options is intended to be
used as a seeding/fertilizing implement when
operated according to instructions and safety
precautions in this manual, machine decals, or other
information provided with the machine.
The drill has straight arm, double disk openers. The
opener disks make a seed furrow, and seed tubes
mounted between the disks place seed in the furrow.
Press wheels following the opener disks, close the
furrow and gauge the opener seeding depth.
The drill features active hydraulic down pressure on
the opener frames. Constant down pressure ensures
even opener penetration in uneven ground. Hydraulic
down pressure is adjustable at a single point.
A drill equipped with one-compartment boxes can be
used to drill either seed or small seed.
A drill equipped with two-compartment boxes allow
two different materials to be put down in the same
field pass. Dividers separate each drill box into two
compartments with an equal amount of feed cups for
each compartment. The two-compartment boxes
can be used for combinations, such as seed and
fertilizer, small seed and fertilizer, seed and small
seed, or small seed and small seed.
Use this implement to seed production-agriculture
crops in conventional or minimum tillage
applications. Do not modify the drill for use with
attachments other than Great Plains options and
accessories specified for use with the
BD7600-26 Drill.

Great Plains | 195-612M | 07/09/2021 12
Preparation and Setup
This section helps you prepare your tractor and drill
for use. Before using the drill in the field, hitch the drill
to a suitable tractor to inspect the systems and setup
the drill.
Pre-Setup Checklist
Read and understand “Safety Information”
beginning on page 3.
Check that all working parts are moving freely,
bolts are tight, and cotter pins are spread.
Check that all grease fittings are in place and
lubricated. See “Lubrication” on page 61.
Check that all safety decals and reflectors are
correctly located and legible. Replace if
damaged. See “Safety Decals” on page 6.
Inflate tires to the pressure recommended and
tighten wheel bolts as specified. See
“Specifications” on page 66.
Hydraulic Hose Connections
High Pressure Fluid Hazard
Escaping fluid under pressure can have
sufficient pressure to penetrate the skin.
Check all hydraulic lines and fittings before
applying pressure. Use paper or
cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. If
injured, seek immediate medical attention
from a physician familiar with this type of
injury.
Equipment Damage Risk
Use the proper hydraulic block to operate
openers, which depends on the type of
tractor hydraulics. If you are not familiar with
your tractor hydraulics, ask your dealer.
Hydraulic hoses have color coded handle grips to
help when connecting the hoses to the tractor
outlets.
To distinguish hoses on the same hydraulic circuit,
refer to the symbol on the handle grip. Hoses with an
extended-cylinder symbol feed the cylinder base
ends. Hoses with a retracted-cylinder symbol feed
the cylinder rod ends.
Electrical Connections
Make sure the tractor is shut down with accessory
power off before making the following connections:
lighting connector to tractor outlet
console connector to tractor harness
any optional or after-market electrical connectors.
These connections can be made in any order, and
must be made before moving the drill.
Hitch Drill to Tractor
Crushing Hazard
Serious injury or death can result when
standing between drill and moving tractor.
Do not stand or place any body part
between drill and moving tractor when
hitching drill. Keep others away. Stop
tractor engine and set parking brake before
installing hitch pins, and attaching
harnesses and hoses.
Negative Tongue Weight Hazard
This drill can have positive and negative
tongue weight, which can work the hitch
pin loose during transport. To avoid serious
injury, always use a clevis hitch or clevis
draw bar with locking-style hitch pin.

Drill Hitches
The drill has the following hitch options:
Clevis hitch
Single-tang, large hole
Single-tang, small hole
Scharmüller Cat 3
Cat 3/4 swivel type hitch
Use the clevis hitch with tractors that have single-tang draw bars. Use the single-tang hitch for tractors with
clevis draw bars. Always use a locking-style hitch pin sized to match the holes in the hitch and draw bar.
Hitch Height
Adjust the drill hitch to match the tractor draw bar height.
1. Extend the jack so the lowest hitch hole is 18 inches (45.7 cm) above ground level (A).
2. Install the drill hitch onto the tongue to match the tractor draw bar height. The hitch can be turned over for
six different hitch heights.
Always have two bolts in two holes of both the tongue and hitch.
(B) 32.0 in (81.3 cm)
(C) 29.0 in (73.7 cm)
(D) 26.0 in (66.0 cm)
(E) 21.5 in (54.6 cm)
(F) 18.5 in (47.0 cm)
(G) 15.5 in (39.4 cm)
When hitching the drill to a different tractor, check for a difference in draw bar heights. Adjust hitch
height as necessary.
3. Securely attach the safety chain to an anchor on the tractor capable of pulling the drill.

Great Plains | 195-612M | 07/09/2021 14
Hitch Installation
Install the hitch (1) onto the tongue and secure with
the bolt (2), lock washer, and nut. Assemble the
safety chain (3) and washer (4), and secure with the
longer bolt (5), lock washer, and nut.
Hydraulic System
High Pressure Fluid Hazard
Do not attempt to make hydraulic system
repairs. Great Plains strongly recommends
that all hydraulic system repairs are
completed by a trained professional who is
knowledgeable about how to safely
complete hydraulic system work. You
should only maintain or adjust your
hydraulics as described within this manual.
Compromising a closed hydraulic system
can cause serious injury or death.
The hydraulic system is fully charged and bled at the
factory prior to shipping. During routine use, cycle
hydraulics several times to purge air. If cycling the
hydraulics fail to produce smooth hydraulic motions, it
may be a sign that your hydraulic system may need
to be bled or otherwise serviced by a trained
professional; contact your Great Plains dealer for
service.
Frame Adjustments
Negative Tongue Weight Hazard
Raising openers on an unfolded, unhitched
drill will cause drill tongue to rise suddenly,
which can cause serious injury or death.
Make sure drill is hitched securely to tractor
draw bar, and safety chain is securely
attached to tractor before raising openers
and unfolding drill.
Frame adjustments are necessary prior to initial field
use. Adjustment instructions assume the drill is unfolded
and will remain attached to a suitable tractor, in the field,
and the hitch height adjustment has already been
completed. See “Hitch Height” on page 13 for more
information.
Wing Box Alignment
1. Place blocks ahead of the wing gauge wheels.
2. Pull forward against the blocks to rock the wing
frames back.
3. Pull forward until the stop bolts (1) are firmly
against the center drill frame.
4. Run a string line across the back of the drill
toward the outer ends of the wings.
5. For proper alignment, the outside ends (3) of the
wing boxes should be about 1 inch (2.5 cm)
ahead of the inside ends (2).
6. To adjust the box alignment, shorten or lengthen
the stop bolts to change the contact point with the
drill frame. Loosen the jam nut and adjust the
stop bolts in or out until the outside ends of the
boxes are about 1 inch (2.5 cm) ahead of the
inside ends.
7. Tighten the jam nut.
