PTO HORSEPOWER REQUIREMENTS
• PTO horsepower requirements are based on most normal dairy or beef rations. Horsepower requirements may vary
depending on the ration or material to be mixed.
• Refer to tractor weight requirements for these recommendations and transporting safety precautions for additional
tractor and towing requirements.
DRAWBAR ATTACHING SYSTEM
• Adjust tractor drawbar and/or the mixer clevis hitch so that the mixer is approximtely level. The top of the drawbar
should be 8”-12” below the tractor PTO shaft. Adjust the drawbar horizontally so that the hitch pin hole is 14”-16”
behind the tractor PTO and the drawbar is centered and locked into place.
• A hitch pin with a minumum of 1”diameter with a retainer pin is recommended for the 4400 mixer. A 1-5/16”diameter
hitch pin with a retainer pin is recommended for the 4500, 4600 & 4700 models.
HYDRAULIC SYSTEM
• Dual hydraulic outlets are required for operating the door and either the slide tray or the powerchute. If your tractor
has only a single set of ports, then either the 3 bank valve option or one of the 2 hose with manual selector valve
options should be ordered. On units with the power chute option, the chute hoses may be dicult to connect due
tothechuteweightontheliftcylinder.Liftweightochutecylindertoconnecthoses.Tractorhydraulicsystem
requirements are 6 GPM @ 1500 PSI when a slide tray is used, 15 GPM @2000 PSI when a 3-auger power chute is used.
MIXER SETUP
• Check for proper assembly, adjustment, and lubrication. Check to see that there is adequate oil in the oil bath. If power
chute is used, oil the roller chains. Check all bolt and set screws are tight.
• Be sure all shields are properly in place.

BEFORE attempting operation.
MIXER OPERATION
Always refer to Equipment Safety Guidelines & Before Operation sections of this manual before operating this mixer.
• The Maxi-Mixer was designed for blending dairy and beef rations. Most commonly used ingredients, including limited
amounts of dry stem hay, can be mixed quickly and uniformly in this mixer. If you have questions regarding your feed
ration or have other applications, please contact Sioux Automation Center, Inc.
• TheMaxi-Mixermixingperformancecanvarygreatlyaccordingtothedierencesinmaterials,loadingsequence,mixing
speed, and unloading methods.
GENERAL
• When the mixer is in operation it has many moving parts which could cause severe injury or death to persons coming in
contact with these parts. To help avoid serious accidents, please read and understand this manual.
SAFETY
• Do not load hay without other dry commodities in the mixer rst to act as a carrier or “lubricant”.
• Do not overload hay content, Sioux Automation Center Inc. recommends up to 15%-20% of hay by weight in the load.
Exceeding this percentage can decrease mixing performance or could potentially damage mixer and cause premature
wear on driveline components.
LIMITATIONS
• Do not use tough hay (20%-60% moisture) Always used cured, dry hay. Wet hay, foreign objects or overloading may
cause binding and damage to the mixer.
• Keep in mind the overall size of the mixer to allow clearance through doorways.
WARNINGS
• The mixer can mix an average load in 3 to 5 minutes. Due to this short mixing time, there is normally no reason to run
the mixer during loading except to level the materials or to breakup hay.
MIXING TIME
• When deciding when and how fast to operate the mixer, factors such as ingredients being used, the thoroughness of
the mix, and the time available to mix must be considered. Normal mixing speed is 3/4 to full PTO speed.
• Do not exceed rated PTO speed. When the mixer is operated faster than rated PTO speed the strain on the drive train and
mixer is greatly increased.

high grass content, high density bales,outdoor storage, use of hay preservatives, and excessive stem length.
HAY QUALITY
• Priortoloading,checkmixerforforeignobjectsandbesurethedoorisfullyclosed.
1. Load Commodities
• Adding ingredients like corn, soybean meal, cottonseed, etc. will act as a carrier or “lubricant” if hay is included
in the ration.
• If there are few commodities in the ration, substituting corn silage or haylage is preferred.
• Fill mixer between 1/3-1/2 full by volume in commodities and forage before adding the hay to the ration. This
will allow enough room for the hay to expand and bring feed level up so the top auger can assist in processing.
2. Load Hay
• Load processed hay. With the mixer running at 3/4 to full PTO speed, proceed loading the small square bale pieces
or tub ground hay into the mixer. Do not exceed 15%-20% of hay by weight.
3. Finish Loading Commodities
• Finish loading any other ingredients to complete the ration in order of least binding ingredient to most binding.
Example: dry commodities rst, corn silage second, haylage last.
4. Finish Loading Wet Commodities
• Any other wet feeds may be added at this time.

• FORAGES- Chopped hay, corn silage, and nely chopped crop residue can be mixed in the mixer. Wet and heavy forages
added in large volumes may require more power to mix.
• GRAINS- Ground, rolled, aked, and whole cereal grains, minerals, and concentrates, are all very easily mixed, and can
improve the mixing performance of the other materials.
• LIQUIDS- Supplements and liquid fat can be blended in the mixer. Some operators prefer adding liquids into the empty
mixer, and others add liquids on top of grains or roughage. Sticky liquids such as molasses tend to increase the power
requirements.

• Do not overload the mixer! Overloading causes excessive horepower requirements, increased strain on the mixer
driveline and poor mixer performance.
FILL LEVEL
• After the ration has been thoroughly mixed, open the mixer door to begin unloading. If the mixer is equipped with
a power chute, the chute must be running before the mixer door can be opened. The combination of the discharge
door opening and the mixer speed determines the ow of feed from the mixer. The door must be opened far enough
to prevent separation of materials, optional door ow control plates are available to help prevent separation. To stop
theowoffeed,closethedoor,(turnothepowerchute)thenshutothemixer.
• The Maxi-Mixer can be equipped with either a power chute, or a slide tray to assist in the delivery of feed. The chute
and tray heights are adjusted with hydraulic cylinders, but the chain stops provided on power chutes should be ad-
justed so that the chute clears all bunks, obstacles, etc.
UNLOADING
INSPECTION AND ADJUSTMENTS
IMPORTANT! READ BEFORE OPERATING MIXER. IT IS THE RESPONSIBILITY OFTHE OWNERTO MAKE
SURETHE MIXER IS SET UP PROPERLY. THE FOLLOWING RECOMMENDATIONS SHOULD BE HELPFUL
• Roller Chain Tighteners so they apply sucient spring tension to keep roller chains running smoothly. The chain will form
grooves in the tightener blocks. These grooves help to keep the chains in proper alignment, and the blocks need not be
turned unless the roller portion of the chain has worn into the block.
• Roller Chains for wear, proper alignment and tension. Adjust or replace if necessary. Roller chain connector links which
pass over polyethylene tightener blocks must have the legs of the cotter pins trailing to the direction of rotation.
• Safety Decals for readability. If any safety decals are removed, obstructed, or otherwise not understandable, they should
be replaced immediately. Keep all decals clean and visible.
• Safety Shielding to be sure all shielding is in place and functions properly. Replace all damaged or missing shielding
immediately - see parts pages for more information.
• Bolts and Set Screws after a few hours of use and each month thereafter. Tighten if necessary.
• Upper Auger Knives can be turned over for use on a new cutting edge and should be periodically sharpened, or replaced
if they are no longer suciently breaking up material.
• Lower Auger Round Knives can be rotated several times before sharpening or replacement is required.
• Discharge Chute Augers (optional) to keep from rubbing on the chute body: There are shims behind each chute auger
bearing for alignment. Periodically check chute liners for wear, replace as necessary.
• Trailer Hitch for proper location, alignment and tightness of attaching bolts. If the upper clevis bar becomes excessively
worn the hitch assembly should be unbolted and replaced as necessary. Frequently check the clevis attaching bolts for
tightness, and that the clevis is secure. Worn or damaged bolts must be replaced.

10-bolt rim: 300 ft lbs-Grade 8 Lug
• Tire Wear and Pressure must be checked to ensure that there is no excessive wear, and that tires are inated to the rec-
ommended operating pressure for each given tire.
• Rain can accumulate in mixer if stored outside, always remove drain plugs on hopper ends to allow unit to drain completely
and replace drain plugs before next use.
• FreezingWeather the PTO shield requires extra grease to prevent freezing. Snow can accumulate in mixer if stored outside,
always remove drain plugs on hopper ends to allow unit to drain completely and check hopper for snow or ice buildup
before operating unit. Thaw and remove any obstruction and replace drain plugs before next use.
IMPORTANT: WHEN WELDING ON THIS UNIT: Do NOT allow the current to ow through the bearings, roller chains, or scale
weigh bars. Ground directly to the item being welded. ALWAYS disconnect weigh bar cords from scale indicator before welding.
INSPECT AND ADJUST
• Scale Indicator: Refer to the electronic scale operators manual for adjustment information. The operator’s manual
for the Electroic Scales should be kept with this manual. Additional scale manuals may be obtained through Sioux
Automation Center, Inc.
• Load Cells: Should be kept clean, dry,and lubricated to insure dependabiltiy.
• Normal Scale Activity: Some warm up scale“drift”may occur after the scale is turned on but should zero balance within
10-15 minutes. Scale may zero shift over night due to temperature changes.

• It is extremely important that the following lubrication schedule be followed: Bearings: use a good quality
multipurpose grease. Replace all damaged or missing grease zerks immediately. Always clean zerks before using
grease gun. Pump the grease in slowly until a slight bead forms around the bearing seals. Once a month check lines
and connections on grease banks for leaks.
• Oilbath Oil: Use a good high quality universal oil. Use an oil that meets or exceeds hydraulic oil grade. Fill to the top
lower oilbath roller chains. Change yearly or whenever contaminated.
• Before operating a new mixer, the roller chains should be liberally lubricated and then the unit operated under a
no-load condition. This break-in period will allow the roller chains to be thoroughly lubricated and thus minimize
heat-up during operation.
