INTRODUCTION
The Buhler Farm King 8” and 10” unloading augers reach where normal portable augers
can’t. They feature a loading hopper that fits right under hopper bottom bins and
hopper trailers for fast and easy access. With a hopper that is almost four feet square
and your choice of 8” or 10” diameter tubing, the Buhler Farm King unloading augers
transfer your grains and oilseeds much faster than conventional utility augers. The
weight is evenly distributed on either side of the pivot wheels. Because the unit is so
well balanced, it can be easily positioned by one person with a minimum of effort.
A hinged cleanout gate in the bottom of the hopper makes thorough cleaning simple.
You do not need to worry about spoiled grain or rusting that can occur when grain is left
sitting.
Buhler Farm King gives you a choice between hydraulic or electric motor. Adjustable
discharge height lets you position the auger to fit the job. Now, you can unload hopper
bins and trailers more quickly and easily than ever before.
Keep this manual handy for frequent reference. All new operators or owners must
review the manual before using the equipment and at least annually thereafter. Contact
your Buhler Dealer if you need assistance, information, or additional copies of the
manual. Visit our website at www.buhler.com for a complete list of dealers in your area.
The directions left, right, front and rear, as mentioned throughout this manual, are as
seen facing in the direction of travel of the implement.

SAFETY
Remember, YOU are the key to safety. Good safety practices not only protect you, but
also the people around you. Make these practices a working part of your safety
program. Be certain that everyone operating this equipment is familiar with the
recommended operating and maintenance procedures and follows all the safety
precautions. Most accidents can be prevented. Do not risk injury or death by ignoring
good safety practices.
The alert symbol is used throughout this manual. It indicates attention is required and
identifies hazards. Follow the recommended precautions.
The safety alert symbol means…
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
CAUTION
The caution symbol indicates a potentially hazardous situation that, if not avoided, may
result in minor or moderate injury. It may also be used to alert against unsafe practices.
WARNING
The Warning Symbol indicates a potentially hazardous situation that, if not avoided,
could result in death or serious injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against unsafe practices.
DANGER
The Danger Symbol indicates an imminently hazardous situation that, if not avoided will
result in death or serious injury. This signal word is to be limited to the most extreme
situations, typically for machine components that, for functional purposes, cannot be
guarded.

affect function or safety, and could affect the life of the equipment.
Inspect and clean the working area before operating.
Keep hands, feet, clothing, and hair away from moving parts.
Ensure bystanders are clear of the area before operating.

TRANSPORT SAFETY
Review Transport Safety instructions in tractor manual before moving.
Check with local authorities regarding transport on public roads. Obey all applicable
laws and regulations.
Make sure the SMV (Slow Moving Vehicle) emblem and all the lights and reflectors that
are required by the local highway and transport authorities are in place, are clean, and
can be seen clearly by all overtaking and oncoming traffic.
Take extreme caution in maneuvering on or around tight corners so as not to catch the
end of the auger on trees, buildings, power lines, etc.
When moving the auger on the road, always use a red flag, or if absolutely necessary to
move at night, accessory lights for adequate warning to operators of other vehicles.
Always travel at a safe speed.
Inflate transport tires to recommended pressure.
SERVICE AND MAINTENANCE SAFETY
Stop engine, set brake, remove ignition key, and wait for all moving parts to stop before
servicing, adjusting, repairing, or unplugging.
Support the equipment with blocks or safety stands before working beneath it.
Follow good shop practices including
- Keep service area clean and dry
- Be sure electrical outlets and tools are properly grounded
- Use adequate light for the job
Use only tools, jacks, and hoists of sufficient capacity for the job.
Replace and secure all shields removed during servicing before operating.
Use heavy leather gloves to handle sharp objects.
Check hydraulics regularly for leaks. Use cardboard to look for leaks, and use hand and
eye protection.
Relieve pressure on hydraulic system before repairing or adjusting.
Failure to follow proper procedures when mounting a tire on a wheel or rim can produce
an explosion, which may result in serious injury or death.
STORAGE SAFETY
Store the unit in an area away from human activity.
Do not permit children to play on or around the stored machine.
Support the frame on stands and blocks to provide a secure base.
SAFETY SIGNS
The following illustration shows the approximate location and detail of safety signs.
Keep all safety signs clean and legible and replace any that are damaged or missing.
When original parts are replaced, any safety signs affixed to those parts should be
replaced as well. Replacement safety signs are available from your local dealer.

SAFETY SIGN INSTALLATION
To install safety signs, ensure the installation area is clean and dry. Decide on the
exact position before you remove the backing paper. Remove the smallest portion of
the split backing paper and align over the specified area. Carefully press in place.
Slowly peel back the remaining paper and smooth the remaining portion in place. Small
air pockets can be pierced with a pin and smoothed out.

ASSEMBLY INSTRUCTIONS
1. Bolt the hopper and tube together using six ½” x 1 ¼” hex bolts, lock
washers, and hex nuts on the 10”. Use 3/8" x 1" hex bolts on the 8”.
2. Bolt the stand to the tube using four ½” x 1 ¼” hex bolts, lockwashers, and
hex nuts. The stands have a high and low position (see chart).
2. Bolt the rubber strips around the hopper using the metal strips and plates
supplied. Use ¼” x ¾” hex bolts, lockwashers, and hex nuts.
3. Hydraulic only – attach the two ½” x 18” hydraulic hoses from the valve
to the hydraulic motor.
4. Motor Drive only -
- Assemble motor mount using ¾” nuts.
- Mount 12" pulley on flighting and 3 ½” pulley on motor. Use a 1725 rpm
motor with 3 to 5hp and a B-54 V-belt.
- Mount belt guard using ¼” x 1" hex bolts and ¼” hex nuts.

8” & 10” Unloading Auger

OPERATING INSTRUCTIONS
When operating an auger for the first time when new, or at the beginning of a season,
run only partially full until flighting becomes polished. Also check the spout and hopper
for bird nests or other obstructions before starting the auger.
The set screws in the universal joint joining the hopper and tube flighting must be
checked regularly and tightened if necessary. The brass bushing in the bushing holder
inside the hopper is another part that should be checked regularly and replaced if
necessary.
To check or service the universal joint or the brass bushing holder, remove the cover at
the front of the hopper.
Hydraulic Unloading Auger:
Approximate hydraulic requirements are:
12 gallons per minute pump capacity
1200-1400 psi hydraulic pressure
Auger rpm and capacity are adjusted using the flow control valve.
Motor Drive Unloading Auger:
Power requirement is from 3 to 5 horsepower electric motor 1725 rpm. Use the 12 inch
double pulley supplied on the auger. The 3 ½” double pulley with b-grooves and two B-
54 V-belts must be supplied by the customer. A 3 horsepower should be sufficient for
the 8”.
Both kinds of unloading auger have wheel stands with adjustable height. Specifications
are given on a chart included in the manual.

THEORY OF OPERATION
MAINTENANCE AND STORAGE
Lubricate the universal joint about every five hours and check to see that the set screws
in the universal joint are tight.
Clean the auger thoroughly after using as dirt draws moisture and causes metal to rust.
Store in a dry place if possible.
Remove belts and store in a cool dry place if auger is to be left outdoors.
At this time check all parts for wear and order replacement parts from your nearest
dealer.
When taking the auger out of storage, check inlet and outlet ends for obstructions and
check all bolts and set screws before using the auger.
ALERT: When replacing bearings or tightening a loose bearing collar, always
tighten collar, always tighten collar in the direction of shaft rotation
using a center punch or a similar tool.
Recommended tire pressure is 32 psi.
