INTRODUCTION
REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!
No accident-prevention program can be successful without the wholehearted cooperation of the
person who is directly responsible for the operation of the equipment.
To read accident reports from all over the country is to be convinced that a large number
of accidents can be prevented only by the operator anticipating the result before the accident is
caused and doing something about it. No power-driven equipment, whether it be transportation or
processing, whether it be on the highway, in the harvest field, or in the industrial plant, can be
safer than the man who is at the controls. If accidents are to be prevented--and they can be
prevented--it will be done by the operators who accept the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help; and they will
help, but their combined efforts can be wiped out by a single careless act of the operator.
It is said that, "the best kind of a safety device is a careful operator." We, at Killbros. ask
that you be that kind of operator.
Thank-You!
Killbros.
The following pages will provide you with infor-
mation regarding safety, operating and servic-
ing instructions for your new product. Use

OPERATIONS
ELECTRICAL HOOK-UP
DO NOT attempt to install, attach, or repair any electrical applications on the cart if work
area is wet. Allow area to dry before any work is to be done. Electrical shock or electrocution may
result if work area is not dry.
Your Grain Cart is supplied with a seven-point SAE connector plug, which will adapt to the
receptacle found on several new tractors on the market today. If not available, an SAE J S60A
seven-point outlet socket can be purchased from your Killbros dealer (order #104838).

The following schematic complies with ANSI/
ASAE Standard S279.9/SAEJ137 for new pro-
duction tractors. NOTE: Wiring specifications
may be different for older tractor models.
Consult your tractor operator’s manual or dealer
for proper wiring and installation. (Fig. 1) OM02482 Fig. 1
TRACTOR HOOK-UP
Make certain that you can see the driver and the driver can see you at all times to avoid
being struck by tractor while attempting to hook up the Cart.
--Make sure sufficient counterweight is used on the tractor’s front-end.
--Move draw bar into shortest position.
Selecting the proper hitch pin size for your tractor!

--With cart hitched to tractor, hook up P.T.O. (see pg. 9-C), following all safety precautions.
--Hook up 7-point electrical plug connection to tractor.
--Be sure hitch is positioned as shown. Gusset should be to top.
HYDRAULIC HOOK-UP
CAUTION! When coupling hyd. hoses to ports on tractor, be sure that coupler ends are
clean of dust, dirt and debris. Failure to do so could contaminate hydraulic system resulting in
excessive wear and possible failure.
-- Properly identify the hoses for the auger fold and the flow control operation.

8
-- It is advisable to use the hydraulic control lever closest to the operator (most commonly known
as control lever No. 1) to activate the flow control.
-- Once everything has been hooked up, test for any possible needed adjustments:
-Are tires inflated to proper pressure?
-Do Augers run smoothly?
-Does Dump Auger fully extend?
-Does P.T.O. operate properly?
-Is Slip Clutch set too loose or too tight?
-Do Flow Control Gates operate properly?
-Is Indicator Arm working properly?
-Are all lights working properly?
If any one of these is not adjusted properly please read the SERVICE section outlined in the
manual or contact your nearest KILLBROS dealer for further information.
With everything in good operating condition, be sure to close flow control gates before use.
OPERATION IN FIELD
The Grain Cart is not insulated. Keep away form all electrical lines and devices. Electro-
cution can occur without direct contact.
1. Make sure the flow control door is in the closed position before loading into the cart.
2. Engage PTO at a low RPM; and open flow control gate.
3. Increase speed to approximately 850 RPM for optimum unloading performance.
4. Use the flow control opening to slow the rate of the flow rather than the tractor’s RPM.
NOTE: If overload causes the clutch to slip (standard PTO drive) or motor to stall (hydraulic drive),
stop auger immediately. Excessive heating of the clutch will require replacement of internal parts.
Close flow control door and relieve auger unloaded pressure by opening bottom pit dump door to
remove some grain from auger.
5. Do not disengage the auger with the flow control open. Excessive start-up torque may result,
putting stress on the cart driveline and your tractor.
6. Properly identify the tractor remotes for proper hook-up of the flow control and auger fold. A
mix-up can damage the auger drive system.
7. Under any circumstance, DO NOT enter the cart with the auger or tractor running.
8. It is strongly advised that the unloaded auger always be returned to the transport position when
not in use.
Operating the PTO
When finishing operation of PTO driven equip-
ment, shift PTO control to neutral, shut off
the engine and wait until the PTO stops be-
fore getting off the tractor and disconnecting
the equipment.
Do not wear loose clothing when operating
the power take-off, or when near rotating equip-
ment.
To avoid injury do not clean, adjust, unclog,
or service PTO driven equipment when the
tractor engine is running.
Never exceed the recommended operating
speed for the particular equipment in use.
PTO drive shafts must only be used for their
intended purpose.
PTO drive shafts, clutches and freewheels are
designed for specific machine types and power
requirements. They must not be replaced by
other models.
NOTE: See the tractor and implement manu-
facturers’ operating instructions.
Ensure that the PTO shaft is securely con-
nected.

9
A.Only use a completely shielded drive sys-
tem:
PTO drive systems with complete shielding,
include the tractor master shield and imple-
ment shielding installed all the time. If any
component of the shield system has been
removed for any reason it, or an identical
replacement part, must be installed before
operation.
B.Maximum Joint Angles:
1. Joint (Standard Type)
Continuous operation - 25 degrees
Short duration - 45 degrees
Stationary - 90 degrees
Check shaft articulation and clearance zone!
Joint articulations of more than 45 degrees
lead to damage. Contact between PTO drive
shaft and tractor or implement (e.g. three point
hitch, drawbar) lead to damage.
C. Coupling the PTO drive shaft (Fig. C1)
Twist Lock
1. Twist locking collar and simultaneously
push PTO drive shaft onto PTO shaft until
the locking device engages.
Check to insure all the locks are se-
cure before engaging the PTO drive shaft.
D. Lubrication (Fig. D1-D3)
Lubricate with quality grease before starting
work every 8 operating hours. Clean and
grease PTO drive shaft before each prolonged
period of non-use.
Molded nipples on the shield near each shield
bearing are intended as grease fittings and
should be lubricated every 8 hours of opera-
tion. Telescoping members must be lubricated
to operate successfully regardless of whether
a grease fitting is provided for that purpose.
Telescoping members without fittings should
be pulled apart and grease should be applied
manually. Check and grease guard tubes in
winter to prevent freezing.
E.Chains (Fig. F1-F3)
NOTE: The chain is intended to prevent the
shield from rotating against non-moving parts,
thereby preventing shield damage. A properly
installed chain will increase the service life of
the shield.

G.Assembling guard:
1. Grease collar groove and inner profile tube.
2. Fit shield tube into collar by centering the
slots over the collar teeth.
3. Align cone, centering grease nipple to
grease filling hole on collar. Press down-
ward to connect.
4. Make sure the three collar tabs are prop-
erly engaged by tapping on cone.
H. Slip Clutch - preset at factory
Damage may occur to other parts of the grain
cart if the spring tension is not set properly.
Correct operating procedure of the slip clutch
is to have it slip slightly with each use.
1. If adjustment is necessary, length from
flange surface to under side of nut should
be 29.25 MM (1.15”).
2. Tighten nuts following an alternating cross
pattern until reaching the height specified.
Check that height is constant for all
springs.
3. If too much slippage occurs, only tighten
each nut a quarter of a turn at a time.
This quarter turn will increase the torque
approximately 500-750 inch lbs.
4. After extended time without use, the slip
clutch may “freeze up”. It is very impor-
tant at the beginning of each season to
loosen the nuts, slip the clutch, and re-
tighten the nuts to the correct length.
1. Chains must be fitted to allow sufficient
articulation of the shaft in all working po-
sitions. Care must be taken to be sure
that chain does not become entangled with
drawbar hitch or other restrictions during
operation or transport of machine.
2. The PTO drive shaft must not be sus-
pended from the chain when PTO is not
in use or unattached from drive unit.
3. If chain should become unattached, do
not attempt to reattach it with the PTO
engaged. Turn off PTO and tractor engine
before making any repairs. If chain is
missing, replace it before use.
F.Dismantling guard:
1. Keep cone pressed downward and release
collar tabs by pushing with a screwdriver.
Push cone off tube.
2. Spread collar to remove from tube.
3. Slide tube off the shaft.

PLEASE READ THE
FOLLOWING INFORMATION
BEFORE USING YOUR SCALE!
THE FOLLOWING STEPS MUST BE CONSIDERED WHEN USING YOUR SCALE AND TO REAL-
IZE ITS BEST PERFORMANCE. DIGI-STAR SCALES ARE MANUFACTURED TO PROVIDE 1/2%
MAXIMUM ERROR. A GOOD INSTALLATION AND PROPER USE ARE REQUIRED IN ORDER TO
OBTAIN ADVERTISED ACCURACY.
A GOOD INSTALLATION REQUIRES THAT ALL LOAD CELLS ARE PROPERLY INSTALLED WITH
“TOP” ACCURATELY POSITIONED.
OPERATION
TO INSURE + OR -1/2% MAXIMUM ERROR, THE UNIT MUST BE USED AS A STATIONARY
LOAD-OUT WEIGH HOPPER FROM BIN TO TRUCK, FOR EXAMPLE, THE GROUND MUST BE
SMOOTH AND LEVEL WITH MAXIMUM 5” SLOP PER 10 FEET.
TO INSURE + OR -1% MAXIMUM ERROR, THE UNIT MUST BE USED SO THAT ALL WEIGHT
MEASUREMENTS OCCUR ON FLAT SMOOTH GROUND (MAXIMUM OUT OF LEVEL 10” IN 10
FEET) IDEALLY, ALL WEIGHT MEASUREMENTS FOR A FIELD WOULD OCCUR IN THE SAME
SPOT.
WARNING!
ALWAYS DISCONNECT CABLES
FROM SCALE INDICATOR BEFORE

8. A BAD LOAD CELL WILL HAVE A READING
THAT IS EITHER UNSTABLE, OR MAKES THE
INDICATOR FLASH " RANGE", OR IS MORE THAN
THREE TIMES GREATER, OR LESS THAN THE
AVERAGE OF THE OTHERS. ADDITIONALLY, THE READINGS OF YOUR WEIGHT OVER EACH LOAD
CELL SHOULD BE SIMILAR. (PROBABLY 4 TIMES
±
OTHER.) ANY DIFFERENCES COULD BE AN
INDICATION OF A BAD LOAD CELL OR A
STRUCTURAL PROBLEM.

SERVICE TIPS
SELECTING PROPER TRACTOR FOR YOUR CART
Approximate loaded weight of cart -690 -> 41,500 Lbs.
-590 -> 35,000 Lbs.
Approximate loaded hitch weight of cart -690 -> 3,900 Lbs.
-590 -> 3,700 Lbs.
WHEEL NUTS
Check all wheel nuts for tightness before first load. Failure to do so may damage wheel nut seats.
Once seats are damaged, it will become impossible to keep nuts tight. Tighten nuts to 400 ft.Lbs.
Retighten after first three loads and check periodically during first season of use.
TIRE PRESSURE
The following is to be used a general guide for tire inflation. Figures may vary depending on specific
brand of tire used. It is important that tires are inspected after unit is loaded. The tire should stand
up with no sidewall buckling as tire rolls.

U-JOINTS
The U-joint will give you many years of service if grease is applied to each joint and spline weekly.
GEAR BOX
-- To check fluid level, grain cart must be sitting level.
-- The fluid level plug and fill plug is on the tip side of the gear box.
For maximum gear box life:
-- Check oil level every two weeks
-- Replace oil every season, fill to fluid level or 2 quarts 90 weight oil

AUGER SYSTEM
Annually check all bolts, nuts, and set screws.
Perform lubrication as specified. The vertical
auger screw on upper and lower auger tubes
are designed to self align while extending upper
auger. (See fig. 2 for exact location.) If auger
is still misaligned, check the gear box to see
that all hardware is secure and tight. Follow
the instructions listed on page 18 for gear
box adjustment.
OM02525
FLOW CONTROL GATE
The Flow Control Gate is designed to prevent
grain form putting an excess load on the
horizontal auger during initial start-up. If gate
is not working properly check:
-- the hyd. cylinder, making sure hoses are
attached properly, clevis pins are secure, and
fluid level in cylinder is at its recommended
level.
-- for any debris that may have wedged be-
tween gate and auger tube.
-- Indicator rod. See that it is not binding up.
INDICATOR ARM
The Indicator Arm lets the operator know the
position of the flow control gate, open or
closed. This arm is connected to the flow
control gate. If the indicator arm is not work-
ing properly see that the hardware connecting
the indicator rod is secure with flow gate and
not binding up. See flow control gate for fur-
ther adjustments.

ASSEMBLY
Some assembly is required before initial use
and operation. All Grain Carts are shipped
without the upper auger, work light, and hy-
draulic cylinder and hoses installed. The 690
model is shipped without the sideboards in-
stalled. If the dealer hasn’t already installed
all equipment, please refer to the following
guidelines for proper location and installation.
Before operation, double check to see that all
components are installed and working properly
to prevent damage to cart or personal injury.
All components of cart are shipped with cart
and stored in the least likely spot to be
damaged during shipping. All carts are shipped
with 1 upper auger, 1 work light, 1 hydraulic
cylinder, and 4 hydraulic hoses. The 690 Cart
is also shipped with 4 sideboards, 4 corner
braces, and 4 corner filler plates. The upper
auger is noticeable, located behind the ladder.
The hydraulic hoses are secured with cable
ties around the ladder. The hydraulic cylinder
is located on the right frame channel directly
behind front frame standard. The work light is
located, opposite the hydraulic cylinder, in a
box taped to the channel support. See Fig. 3
for locations.
The corner braces and filler plates are lo-
cated in a hardware bag on the frame oppo-
site the hyd. cylinder. The 690 sideboards
are shipped mounted flat on the top of the
cart. INSTALLATION
Refer to (Fig. 5). Remove hydraulic hoses
from ladder by cutting the cable ties used in
shipping. Be careful not to cut hoses. On one
end of each hose is a hydraulic coupler that
will attach to the tractor. Connect the oppo-
site end to the cart. (1) Connect the two
male hoses to the female fittings used for the
upper auger. To prevent damage to these
hoses, secure to outside rail of ladder. (2)
The remaining 2 hoses will attach to the bolts

ADJUSTABLE GEARBOX
OPERATION
Gearbox is pre-aligned at factory and welded,
centered on auger tube. Given time and wear,
gearbox may become out of alignment, caus-
ing excessive vibration and wear to the cart.
To correct this, follow these steps.
1. Break the two tack welds holding the plate
to the cart.
2. With tack welds broke, loosen the (4)
5/8” bolts. Be sure not to loosen them all
the way, auger may drop down, causing
total misalignment, or even injury.
3. With gearbox and plate free to move,
position auger so that it is center with
auger tube. Once centered, retighten bolts.
4. Clear work area and test run auger and
see that auger is centered with auger tube.
5. Once auger is set and centered with tube,
check tightness on bolts and tack weld
plate back into place. Run 2 tack welds
about 1” long on 2 sides of plate.

tom side of the cart for the flow control gate.
(3) U-brackets are welded along the inside
channel for protection of the hydraulic hoses.
Run the hoses between these brackets. (4)
Install work light to upper auger, securing it
to the brackets used for the upper bearing.
(5) Feed wire used for the light through the
channels welded to the backside of the upper
auger. (6) Install the upper auger so that it is
in the rest position, resting on the rest bracket
located to the back of the cart. Position au-
ger, lining up the holes where auger is hinged.
Once aligned secure hinge pin with expansion
pin. Refer to page 21 for hardware listing.
Auger screws will pre-align once upper auger
is extended. (7) Install hydraulic cylinder and
secure with cylinder pins and clips. The upper
auger or cylinder may have to be slightly
extended for proper alignment of cylinder pin
holes. Connect the cylinder hoses to the two
ports located below the lower auger tube.
Secure all hardware, wiring, and hydraulic
hoses and check for leaks.
SIDEBOARDS
Refer to Fig. 4 for locations of each step.
The side boards should be assembled with
care so the paint does not get scratched. (1)
Cut the bands that hold the sideboards to-
gether. (2) Remove the mounting brackets on
the front of the cart. Do not remove side
mounting brackets until after end boards are
in place. Take note that the bolts used for
shipping should also be used for the final
mounting of the sideboards. (3) Stand the
end boards up one at a time using the center
bar on the cart and the cart sides for support.
Swing the end boards around into their final
mounting positions and put two bolts in them
to keep them in place. (4) Remove the side
mounting brackets, also saving these bolts.
(5) Lift the sideboards into place and bolt
them to the cart. (6) Take the corner brack-
Fig.4
ets out of the hardware bag tied to the frame
of the cart. Bolt the corner brackets on the
outside of the sideboards using the top set of
holes on each corner. Use the small corner
bracket on the inside of the sideboards. This
small bracket is reversible so it can be used
on all four corners. Bolt the small bracket on
the bottom set of holes on each corner mak-
ing sure that the bracket covers any gaps
that may exist in the corners. Before using
cart check that all bolts are in place and
tightened. Refer to page 28 for complete
hardware listings and final assembly illustra-
tion.
