General Equipment Safety

SAFETY. . . YOU CAN LIVE WITH IT!

General Equipment Safety Guidelines

Safety of the operator is one of the main concerns in designing and developing a new piece of equipment. Designers
and manufacturers build in as many safety features as possible. However, every year many accidents occur which
could have been avoided by a few seconds of thought and a more careful approach to handling equipment. You,
the operator, can avoid many accidents by observing the following precautions presented in this manual. To avoid
personal injury, study the following precautions and insist those working with you, or for you, follow them.

Replace any CAUTION, WARNING, DANGER or instruction safety decal that is not readable or is missing. Location
of such decals is indicated in this booklet.

Do not attempt to operate this equipment under the inuence of drugs or alcohol.

Review the safety instructions with all users annually.

This equipment is dangerous to children and persons unfamiliar with its operation. The operator should be a responsible
adult familiar with farm machinery and trained in the equipment’s operations. Do not allow persons to operate or

assemble this unit until they have read this manual and have developed a thorough understanding of the
safety precautions and of how it works.

To prevent injury or death, use a tractor equipped with a Roll Over Protective System (ROPS). Do not paint over,
remove or deface any safety signs or warning decals on your equipment. Observe all safety signs and practice the
instructions on them. Never exceed the limits of a piece of machinery. If its ability to do a job, or to do so safely, is in
question - DON’T TRY IT.

HD4SR & 12SR June 2015 1-3

Safety

Lighting and Marking

It is the responsibility of the operator to know the lighting and marking requirements of the local highway authorities
and to install and maintain any additional equipment to provide compliance with the regulations. Aftermarket lighting
kits are often available from your dealer.

This machine is equipped with lighting, marking, and signs in compliance with standards published by the American
Society of Agricultural Engineers for Slow Moving Agricultural Implements on Public Roadways.

Wheels and Tires

Tire Safety

• 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.

• Do not attempt to mount a tire unless you have the proper equipment and experience.

• Inating or servicing tires can be dangerous. Only trained personnel should be called to service and/or mount

tires.

• Only install tires and wheels with appropriate capacity to meet or exceed the anticipated weight to be placed on
the equipment.

DON’T FORGET! Your best assurance against accidents is a careful and responsible operator. If there is any portion
of this manual or function you do not understand, contact your local authorized dealer or the manufacturer.

1-4 June 2015 HD4SR & 12SR

Safety

Bale Skoop Operation Safety

Before Operating

• Carefully study and understand this manual.

• Install the safety warning light to indicate when the hitch is offset.

• Do not wear loose-tting clothing which may catch in moving parts.

• Always wear protective clothing and substantial shoes.

• It is recommended that suitable protective hearing and sight protectors (eye protection) be worn.

• The operator may come in contact with certain materials which may require specic safety equipment, relative to

the handling of such materials (examples: extremely dusty molds, fungus, bulk fertilizers, etc.)

• Keep wheel lug nuts or bolts tightened to specied torque.

• Ensure that the tires are inated to the recommended pressure.

• Give the unit a visual inspection for any loose bolts, worn parts or cracked welds, and make necessary repairs.
Follow the maintenance safety instructions included in this manual.

• Be sure that there are no tools lying on or in the equipment.

• Do not use the unit until you are sure that the operating area is clear, especially of people and animals.

• Because it is possible that this equipment may be used in dry areas or in the presence of combustibles, special

precautions should be taken to prevent res and re ghting equipment should be readily available.

• Don’t hurry the learning process or take the unit for granted. Ease into it and become familiar with your new
equipment.

• Practice operation of your equipment and it’s attachment. Completely familiarize yourself and other operators with
its operation before using.

• Make sure that the brakes are evenly adjusted (if equipped with brakes).

HD4SR & 12SR June 2015 1-5

Safety

Bale Skoop Operation Safety - Continued

During Operation

• SAFETY CHAIN: If the Bale Skoop is going to be transported on a public highway, the safety chain should be
connected. Always follow state and local regulations regarding a safety chain and auxiliary lighting when towing

farm equipment on a public highway. Only a safety chain (not an elastic or nylon/plastic tow strap) should be

used to retain the connection between the towing and towed machines in the event of separation of the primary
attaching system.

• Install the safety chain by crossing the chains under the hitch and secure to the draw bar cage, hitch or bumper
frame.

• Beware of bystanders, particularly children! Always look around to make sure that it is safe to start the engine
of the towing vehicle or move the unit. This is particularly important with high noise levels and quiet cabs, as you
may not hear people shouting.

• NO PASSENGERS ALLOWED: Do not carry passengers anywhere on or in the tractor or equipment.

• The tops of the bed and loader are extremely slippery, do not climb, stand, or crawl on them.

• Keep bystanders at least twenty-ve feet away from an operating machine or stacked hay. This allows bystanders

time to get away from a falling stack or away from a moving machine. The operator is a very busy person and it
is easy to miss seeing an observer while operating the Bale Skoop.

• Keep hands and clothing clear of moving parts.

• Do not clean, lubricate or adjust your equipment while it is moving.

• When halting operation, even periodically, set the tractor’s or towing vehicle’s brakes, disengage the PTO, shut
off the engine and remove ignition key.

• Be especially observant of the operating area and terrain - watch for holes, rocks or other hidden hazard. Always
inspect the area prior to operation.

• DO NOT operate near the edge of drop-offs or banks.

• DO NOT operate on steep slopes as overturn may result.

• Operate up and down (not across) intermediate slopes. Avoid sudden starts and stops.

• Pick the attest possible route when transporting across elds. Avoid the edges of ditches or gullies and steep

hillsides.

• Always return the hitch to the in-line position whenever moving from the stack to the bales or the bales to the
stack.

• Be extra careful when working on inclines.

• Periodically clear the equipment of brush, twigs or other materials to prevent buildup of dry combustible materials.

• Maneuver the tractor or towing vehicle at safe speeds.

• Avoid overhead wires or other obstacles. Contact with overhead lines could cause serious injury or death.

• Avoid loose ll, rocks and holes; they can be dangerous for equipment operation or movement.

• Allow for unit length when making turns.

• Do not walk or work under raised components or attachments unless securely positioned and blocked.

• Keep all bystanders, pets and livestock clear of the work area.

1-6 June 2015 HD4SR & 12SR

Safety

During Operation - Continued

• Operate the towing vehicle from the operator’s seat only.

• Never stand alongside of unit with engine running or attempt to start engine and/or operate machine while standing

alongside of unit.

• Never leave running equipment attachments unattended.

• As a precaution, always recheck the hardware on equipment following every 100 hours of operation. Correct all
problems. Follow the maintenance safety procedures.

After Operation (Storage)

• Following operation, or when unhitching, stop the tractor or towing vehicle, set the brakes, disengage the PTO
and all power drives, shut off the engine and remove the ignition key.

• Store the unit in an area away from human activity.

• Do not park equipment where it will be exposed to livestock for long periods of time. Equipment damage and
livestock injury could result.

• The tops of the bed and loader are extremely slippery, do not climb, stand, or crawl on them.

• Do not permit children to play on or around the stored unit.

• Make sure all parked machines are on a hard, level surface and engage all safety devices.

• Wheel chocks may be needed to prevent unit from rolling.

• Adopt safe driving practices. . .

• Keep the brake pedals latched together at all times. NEVER USE INDEPENDENT BRAKING WITH MACHINE

IN TOW AS LOSS OF CONTROL AND/OR UPSET OF UNIT CAN RESULT.

• Always drive at a safe speed relative to local conditions and ensure that your speed is low enough for an emergency
stop to be safe and secure.

• Reduce speed prior to turns to avoid the risk of overturning.

• Avoid sudden uphill turns on steep slopes.

• Always keep the tractor or towing vehicle in gear to provide engine braking when going downhill. Do not coast.

• Do not drink and drive!

• Comply local laws governing highway safety and movement of farm machinery on public roads.

• Be sure stock lights as well as accessory lights are connected and operating properly.

• Use approved accessory lighting, ags and necessary warning devices to protect operators of other vehicles on

the highway during daylight and night time transport. Various safety lights and devices are available from your
dealer.

• The use of ashing amber lights is acceptable in most localities, however some localities prohibit their use. Local

laws should be checked for all highway lighting and marking requirements.

• When driving the tractor and equipment on the road or highway under 20 mph (32 km/h) at night or during the
day, use ashing amber warning lights and a slow moving vehicle (SMV) identication emblem.

• Plan your route to avoid heavy trafc.

• Be a safe courteous driver. Always yield to oncoming trafc in all situations, including narrow bridges, intersections,

etc.

• Watch for obstructions overhead and to the side while transporting.

• Always operate equipment in a position to provide maximum visibility at all times. Make allowances for increased
length, width and weight of the equipment when making turns, stopping the unit, etc.

Maintenance Safety

Performing Maintenance

• Good maintenance is your responsibility. Poor maintenance is an invitation for trouble.

• Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a closed building. The
exhaust fumes may cause asphyxiation.

• Before working on this machine, stop the towing vehicle, set the brakes, disengage the PTO and all power drives,
shut off the engine and remove the ignition key.

• Be sure the bed is lowered against the bed rest and the loader is resting on the hitch or in its lowered position.

• Be certain all moving parts on attachments have come to a complete stop before attempting to perform maintenance.

• Always use a safety support and block the wheels. Never use a jack to support the machine.

• Always use the proper tools or equipment for the job at hand. Use extreme caution when making adjustments.

• A torque chart is provided in this manual for reference when tightening bolts and nuts.

• Never use your hands to locate a hydraulic leak on attachments. Use a piece of cardboard or wood. Hydraulic

uid escaping under pressure can penetrate the skin.

• When disconnecting hydraulic lines, shut off hydraulic supply and relieve all hydraulic pressure (see maintenance
section for instructions).

• Openings in the skin and minor cuts are susceptible to infection from hydraulic uid. If injured by escaping hydraulic
uid, see a doctor at once. Without immediate medical treatment, serious infection, gangrene and allergic reactions

can occur.

• Replace all shields and guards after servicing and before moving.

• After servicing, be sure all tools, parts and service equipment are removed.

• Do not allow grease or oil to build up on any step or platform.

• Never replace hex bolts with less than grade eight bolts unless otherwise specied. Refer to bolt torque chart for
head identication marking.

• Where replacement parts are necessary for periodic maintenance and servicing, genuine factory replacement parts

must be used to restore your equipment to original specications. The manufacturer will not claim responsibility
for use of unapproved parts and/or accessories and other damages as a result of their use.

• If equipment has been altered in any way from original design, the manufacturer does not accept any liability for
injury or warranty.

• A re extinguisher and rst aid kit should be kept readily accessible while performing maintenance on this equipment.

Setting up the Lever Controls

Although you may have your preference of tractor lever control setup, the typical lever conguration is “forward is
for lowering”, and “back is for lifting”. If this is not your standard be aware that the lever operation instructions below

represent this conguration.

Operation

1 Ton Backstop

½ Ton Backstop

3X4 Backstop

Building Stacks

CAUTION: Return stacker to the “in-line”
position when moving between bales in
field and stack. This reduces the chance
of running over anybody or anything in
the field.

Starting Stacks

1. Choose a level area, with enough room to maneuver
a tractor and Bale Skoop even after the stack is
nished. Note: If completely level ground is not
available, then build your stack uphill (front of tractor
and Bale Skoop facing uphill).

2. Begin stack by building a “backstop”. The proper
backstop should be built to withstand backing into the
stack every time a load is delivered. We recommend

the following back stop congurations:

1 Ton Squares: A 2 bale by 2 bale square set at one

end, perpendicular to the length of the bales in the

stack. The rst load in the stack should be only 3

bales tall.

½ Ton Squares: A 3 bale by 3 bale square set at one

end, perpendicular to the length of the bales in the

stack. The rst load in the rest of the stack should

only be 2 bales by 4 bales, with one extra in the

fth tier.

3 X 4 Bales: A 2 bale by 3 bale stack set at one end,

perpendicular to the length of the bales in the stack.

The rst load in the stack should be 4 bales high,

the second 5 bales high, and the rest should be 6
bales high.

5-10 June 2015 HD4SR & 12SR

Stacking

1. After the last bale(s) is/are picked up, raise the loader

all the way up. This squeezes the load between
the forklift teeth and the alignment arms making a
compact load.

2. Position the tractor and Bale Skoop in front of the
backstop.

3. Raise the bed to 70 or 80 degrees (so it is almost
vertical, but the weight of the bales is still clearly
against the bed).

4. Back up until the corner of the bottom bale on the
Bale Skoop comes into contact with the back stop.

5. Continue to raise the bed and back up until the load
is vertical. Important: It is critical that the rst load
into the stack is vertical. To avoid the stack tipping
over, DO NOT ALLOW THE BED TO GO PAST

VERTICAL on the rst load.

6. Lower the loader to release the alignment arms from
the stack.

7. Pull forward slowly, lower the bed all the way, and go
and retrieve another load.

Operation

CAUTION: Avoid overhead wires
to prevent serious injury or death.
Electrocution can occur without direct
contact.

CAUTION: Keep bystanders at least
twenty-five feet away from an operating
machine or stacked hay.

Note: Be sure the loader is raised enough not to hit

the hitch when the bed is lowered all the way.

Gathering Bales

Approaching Bales

1. The easiest way to pick up bales is by driving the Bale
Skoop perpendicular to the path of the baler.

2. Before arriving at a bale “offset” the hitch and lower
the loader all the way down until it is perpendicular
to the ground.

3. Bales are picked up on their 8 foot side.

4. The Auto Align system will allow the operator to
approach the bale from almost any direction.

WARNING: Keep bystanders at least
twenty-five feet away from an operating
machine or stacked hay.

WARNING: Avoid rocks rough terrain,
steep slopes, banks and drop offs when
possible. Always maneuver tractor at safe
speeds.

Operation

Stair-stepping ½ Ton Bales

Gathering Bales - Continued

Loading Bales

1. When the bale is between the alignment arms and
against the loader raise the loader. The alignment
arms will automatically squeeze the bale and then
the loader will raise.

CAUTION: The first bale or pair of bales
that is loaded onto the bed of the Bale
Skoop makes it very front heavy. Caution
must be exercised when the Bale Skoop
is in this position.

If operating a 12SR model Auto Align Bale Skoop

2. When the loader is raised, the alignment arms will
squeeze the bale, and the grab hooks will come from

behind the loader to hold the rst bale.

3. The alignment arms can then be opened to retrieve
the next bale.

Note: Keep the end of the alignment arms 12

to 14 inches (30 - 35 cm)off the
ground in order to pick up the
second bale slightly lower (6-15

inches(15 - 35 cm)) than the rst.

This stair-step will help allow the
bale to slide back without tipping
over.

Note: Keep alignment arms on the rst bale closed

until you get to the second bale.

4. Properly adjusted grab hooks will automatically
disengage when the loader is raised to a horizontal
position.

Operating all models of Auto Align Bale Skoops

5. Raise the loader until it is all the way up. Begin to
lower the loader and the alignment arms will open
allowing the bales to slide to the rear of the bed.

6. Repeat as many times as desired, or until the load
is complete (HD4SR full load is 4 bales (with 4x4
bales), 12SR full load is 12 bales (with 3x3 bales),
with 3 x 4 bales, the full load for both machines is 6
bales). Note: After the last bale(s) is/are picked up,
the loader should not be lowered.

7. Move hitch into the “inline” position before traveling
to the stacking area.

Transporting Bale Skoop

WARNING: Attach safety chain to Bale
Skoop and Tractor before moving on
highway.

CAUTION: Exceeding speeds of 20
mph (32 km/h) is not legal or safe on
public roads. DO NOT exceed 20 mph
(32 km/h) with this machine.

WARNING: Use Hitch Safety Pin to
lock hitch in the in-line position before
transporting Bale Skoop on public roads.
This will secure hitch in case of accidental
activation or failure of hitch cylinder.

REMEMBER: When transporting any piece of

oversized equipment:

• Be familiar with local laws by contacting local
authorities before transporting Bale Skoop on public
roads. Obey all regulations as they pertain to the

Bale Skoop. The specications at the front of the

manual contain most of the information that may be
needed.

• This machine is equipped with lighting, markings,
and signs in compliance with standards published
by the American Society of Agricultural Engineers
for Slow Moving Agricultural Implements on Public
Roadways.

• Use ags, warning lights and slow moving vehicle

signs as they are needed. Flag-persons may be
required by local authorities and may be helpful even
if they aren’t required.

• Always remember the extra width of the Bale Skoop.
The wheels on the Bale Skoop are approximately 10
feet 8 inches (325.1 cm) wide with the implement
tires, 10 feet 8 inches (325.1 cm) wide with the truck
tires, and 11 feet 3 (342.9 cm) inches wide with the

high otation Terra tires.

• Drive carefully at an appropriate speed for the
size and weight of the Bale Skoop. Allow for the
extra length of the trailer when making corners.
Reduce speed when navigating corners to prevent
overturning machine. Link brakes to prevent loss of
control during panic braking.

• Plan route to avoid heavy trafc. Drive in a courteous

manner.

• Never drink and drive!

Operation

HD4SR & 12SR June 2015 5-13

Operation

Tips and Techniques

It takes some time, generally about a week, for an
operator to get used to the controls, the movements,
and the capabilities of the Auto Align Bale Skoop.

Rotating Bales

• If approaching the bale “end-on” is desired, the bale
may be rotated, or spun, by closing the alignment
arms slightly and bumping the end of the bale with
the right alignment arm. When contact is made,
open the arms to push the end to the right causing
the bale to rotate into the loader.

Quarter Turning Bales

• To quarter turn a bale on the ground raise the loader
until the alignment arms squeeze together. With the
ends of the alignment arms positioned about halfway
up the side of the bale, move forward, while raising
the loader.

Note: Quarter turning with a Bale Skoop is very time

consuming and is not recommended for a larger
number of bales in a row.

• To quarter turn a bale with a 12SR model Bale Skoop

grab the rst bale before attempting to quarter turn

the second bale.

Note: Make sure the feet on the slider pipes of the

12SR grab under the edge of the bale, otherwise
they may catch a string.

Repositioning Bales

• If bales are located in a corner or tight place, the
alignment arms can be used to grab a bale and
reposition it in a better working location.

Tipping or Rolling Bales

• If the bales do not have enough stair-step the bales
might roll when traveling down the bed. If you have

to x the amount of stair-step after picking two bales

into the loader just raise the loader a few inches (4”­15” (10 - 38 cm)), then open the alignment arms so

the second bale can slide down in front of the rst.

Raise the loader again and the alignment arms will
re-squeeze the bale.

5-14 June 2015 HD4SR & 12SR

Lining up the center of the tractor with the edge of the stack

Tips and Techniques - Continued

• If the loader has been lifted too far and the grab
hooks have disengaged without enough stair-step
between the bales it is possible to get the bales to
slide on the bed. Most of the time if the bales are
rolling it is because they catch at the hinge between
the bed and the loader. Raise the loader until it is
exactly in-line with the bed and open the alignment
arms.. (Sometimes with wet bales this is the only
way to get the bales to slide.)

Stacking

• For better visibility while building stacks, center the
tractor against the edge of the stack, with the hitch

slightly offset; it is much easier to see what you are

doing. . . stacks turn out straighter too!

Operation

• Fine tune your stack by making minor adjustments
in your steering with the hitch control.

• The bales should be stacked on level ground. When
stacking on a slight incline, stack with the tractor
facing uphill. Stacking downhill or on a slight side

incline will make it difcult to build good stacks.

• If the stack is not tight enough, raise the bed all the
way up, pull the tractor and Bale Skoop forward three
feet, and back into the stack to push the bales tight.

(3) Watch Alignment Arms

The alignment arms are longer than the bales and will contact the stack if they are not opened up before the bed

is raised to its maximum height.

(4) On/Off Strings

The bales come out of the baler “On Strings”. If you want to pick up the bales “Off Strings” you must have a turner

for your baler.

(5) Remove/Add Bed Extensions

With the hitch offset and the loader in its lowest position, remove the pin from the bottom of the bed extension

and lift the extension off the machine. Turn the bed extension 180 degrees so that the front of the extension is
facing the other direction, place the extension back on the machine, and reinsert the pin.

CAUTION

BE ALERT

General

This section deals with two goals, maximum life and
dependable operation. Adopt a regular maintenance

and lubrication program. Care and sufcient lubrication

is the best insurance against delays.

SAFETY FIRST

REFER TO SECTION 1 AND REVIEW

ALL SAFETY RECOMMENDATIONS.

Safety

• Always shut off the tractor and remove key before
dismounting.

• Guard against hydraulic high pressure leaks with
hand and face protection.

• Never work under the implement unless it is in the
down position or securely blocked in place. Do not
depend on the hydraulic system to support the frame.

Warning

Securely support any machine elements that
must be raised for service work.

Caution

Keep service area clean
and dry. Wet or oily

oors are slippery.

6-2 June 2015 HD4SR & 12SR

Tighten Bolts

• Before operating the unit.

• After the rst two hours of operation.

• Check tightness periodically thereafter.

• Use Bolt Torque Chart on page 6-13 for correct
values on various bolts.

• Note dashes on hex heads to determine correct
grade.

Note: DO NOT use the values in the Bolt Torque

Chart if a different torque value or tightening

procedure is given for a specic application.

• Fasteners should be replaced with the same or higher
grade. If higher grade is used, only tighten to the
strength of the original.

Maintenance

Tires

• Inspect tires and wheels daily for tread wear, side
wall abrasions, damaged rims or missing lug bolts
and nuts. Replace if necessary.

• Tighten wheel bolts - refer to Bolt Torque Chart.

• Check tire pressure daily, when tires are cold. Tire

pressures for specic tires are listed in the “Machine
Specication” section at the front of this manual.

• Correct tire pressure is important.

• Do not inate tire above the recommended pressure.

Warning

After the rst 100 hours of use, re-torque all

wheel lug nuts.

Caution

Tire replacement should be done by trained
personnel using the proper equipment.

HD4SR & 12SR June 2015 6-3

Maintenance

Preventative Maintenance

Before operating your Bale Skoop carefully inspect the entire machine, and its components for any sign of excessive
wear or weakness. Always follow the Daily Maintenance, General Maintenance, and Year End Maintenance Checklists
to allow for early detection of possible hazards.

WARNING: Always wear eye protection and proper protective clothing while performing
maintenance on the Bale Skoop. Protective clothing includes, but is not limited to; heavy
pants and shirt, steel toed boots, and gloves.

WARNING: When working with hydraulic fluid you should wear rubber gloves to prevent oil
from getting in cuts and scratches in your skin and causing infections or allergic reactions.

Hydraulic System Preventative Maintenance

DANGER: Remember to turn off hydraulic system and tractor and remove keys from ignition
before servicing the Bale Skoop. The bed and loader should be lowered to their lowest
position or securely blocked in position.

• Maintain tractor hydraulic system and uid according to manufacturers specications. Always use a good quality
hydraulic uid.

• Check the uid level in the tractor with the bed and loader cylinders retracted.

WARNING: Hydraulic fluid escaping under pressure can easily penetrate skin. Openings in
the skin and minor cuts are susceptible to infection from hydraulic fluid. If injured by escaping
hydraulic fluid, see a doctor at once. Without immediate medical treatment, serious infection
and allergic reaction can occur.

• Check for chafng or kinking of the hydraulic hoses, these are a source of leaks in hoses.

• Check hoses and cylinders for leaks and repair as necessary. Remember that hydraulic uid escaping under
pressure can penetrate human skin. Use a piece of cardboard or wood to look for a suspected high pressure leak.

• Replace all hoses or hydraulic components that show any sign of wear, cracks,leaking, etc.

6-4 June 2015 HD4SR & 12SR

Maintenance

Hydraulic Pressure Relief

IMPORTANT! RELIEVING HYDRAULIC PRESSURE FROM LINES

Repairs to hoses and cylinders will usually require disconnecting a tting connection. Fittings should not be

disconnected until the pressure in the hydraulic circuit has been relieved. Follow this procedure to relieve pressure
in the hydraulic lines.

WARNING: Hydraulic fluid escaping under pressure can easily penetrate skin. Openings in
the skin and minor cuts are susceptible to infection from hydraulic fluid. If injured by escaping
hydraulic fluid, see a doctor at once. Without immediate medical treatment, serious infection
and allergic reaction can occur.

WARNING: Always wear eye protection and proper protective clothing while performing
maintenance on the Bale Skoop. Protective clothing includes but is not limited to; heavy
pants and shirt, steel toed boots, and gloves.

WARNING: When working with hydraulic fluid you should wear rubber gloves to prevent oil
from getting in cuts and scratches in your skin and causing infections or allergic reactions.

1. Be sure bed is resting on its rest and loader is resting on the hitch or in its lowest position.

2. Park the tractor and Bale Skoop on level ground, place the transmission in park, set the parking brake, turn
off the tractor, and remove the key. When the tractor is off, move each of the hydraulic levers forward and back
approximately four times.

3. Uncouple the hoses from the tractor. Slowly unscrew the male hydraulic tips on the ends of the stacker hydraulic

hoses, turning them 1/8 th of a turn at a time watching for oil to start leaking out.

4. Use a bucket to catch leaking hydraulic uid.

5. Crack the hydraulic lines to the loader cylinders as they can have oil under pressure caught by the load check
valve.

Warning

HIGH-PRESSURE FLUID HAZARD

To prevent serious injury or death:

• Relieve pressure on hydraulic system before servicing or
disconnecting hoses.

• Wear proper hand and eye protection when searching for
leaks. Use wood or cardboard instead of hands.

• Keep all components in good repair.

Daily Maintenance

WARNING: After the first 100 hours of use, re-torque all wheel lug nuts.

Daily Check

Lubricate Lubricate all grease points with all-purpose, non-clay based grease. See

section for location of grease zerks.

Hitch Connection

Inspect Pins

Inspect Plastic

Inspect Hydraulics

Clean

Check the bolt system that connects the stacker to the tractor drawbar. A loose
connection will wear faster and possibly uncouple.

Check to make sure all pins and bolts are secure in their proper places. Inspect the
pivot pins for wear and replace as necessary.

Check all plastic wear plates for wear or breakage. See section in general
maintenance.

Inspect all hydraulic hoses, ttings, and couplings for signs of wear and x as
necessary. Check hydraulic uid in tractor and general hydraulic system as outlined

above.

Keep the Bale Skoop clean and free from mud and dirt, especially around hydraulic
cylinder rods and moving parts.

Axle Bearings

Wheel Lug Nuts

Tire Air Pressure

6-6 June 2015 HD4SR & 12SR

Check the oil level in the axle hubs and ll with 80-90 gear lube as necessary.

Examine the wheel lug nuts making sure all are tight and none are missing.

Check air pressure in tires. Tire pressures for specic tires are listed in the “Machine
Specication” section at the front of this manual.

Maintenance

General Maintenance

General Check

• Lug nuts should be tightened to 450-500 ft-lbs.

• Axle U-bolts should be tightened to 628 ft-lbs. This amount of torque will crush the threads so the U-bolts cannot
be re-used.

• Alignment arm chains should be kept tight to prevent cracking of the loader. Check the chain tightness by visually
inspecting the chains when the loader is fully raised. The chains should have little or no slack.

To tighten Alignment Arm Chains

1. Jack up the ends of the alignment arms and block them in place. This should create the most slack in the chain.

2. Release the safety latch and unhook the grab hook. Determine the link that would eliminate the most slack in

the chain.

3. Remove the double clevis pin in the end of the chain, hook the grab hook on the desired link, and re-lock the

safety latch.

4. Re-install the pin on the double clevis on the end of the chain through the pad eye on the alignment arm.

• Check all plastic wear surfaces used in the machine. These parts are located at the hitch pivot point, between the
hitch and the frame, at the alignment arm pivots, and in the grab hook pivots (if 12SR model).

• Periodically check all bolts. Use grade eight bolts for replacements. A torque chart is provided on page 6-12.

Cylinder Repair

The diagnosis and repair of the hydraulic cylinders on the Auto Align Bale Skoop should only be attempted by a

qualied service technician familiar with this type of repair.

Bed Extensions

The bed extensions are used to hold the fth tier in a load, depending on the dimensions of the bales being stacked.

Refer to the chart on page 5-16 to determine if your application requires the use of bed extensions. The bed extensions
can easily be removed, turned around, and re-pinned to the bed if it is desired to stack a different sized bale.

HD4SR & 12SR June 2015 6-7

Maintenance

Electrical Maintenance

Electrical components on the SR Bale Skoop do not need regular maintenance unless wires or cable are worn

or broken. This section briey outlines the function of the electrical systems and gives some basic guidelines for

maintenance and repair.

Warning Box System

This is a simple system used to warn the operator that the hitch is not in the in-line position. It consists of a micro
switch mounted on the frame of the stacker, a wire that runs the length of the hitch, and a box with a light which is
mounted in the cab.

Basic Maintenance and Notes

• Always check the wires for wear from rubbing on different components. When wear is detected, move the wires
or shield them.

• When trouble shooting, always check the wires for good connections.

• Use the Electrical Diagrams to rebuild wires if needed.

Wheel Bearing Adjustment

Wheel Bearing Adjustment Procedure (Double Nut Arrangement)

1. Prior to installing any wheel-end fasteners, make sure the spindle area is free of dirt and debris. As well, make
sure all nuts and washers are free of dirt. Clean mating surfaces are important for proper wheel-end assembly.

2. After properly installing the bearing cones and wheel-end seal onto the spindle, and the wheel-end is slid onto the
spindle, tighten the inner spindle nut with a torque wrench to 150-200 ft. lbs. to set the bearings and wheel-end.

CAUTION: DO NOT USE AN AIR IMPACT WRENCH TO TIGHTEN THIS NUT!

3. Loosen this inner nut to allow the brake drum to rotate freely. Backing off one (1) full turn is recommended.

4. Re-tighten the inner spindle nut to 50 ft. lbs. by hand using a torque wrench to position the bearings for nal

adjustment. CAUTION: DO NOT USE AN AIR IMPACT WRENCH TO TIGHTEN THIS NUT!

5. Back the inner spindle nut off 1/4 turn.

6. Install the retaining fastener or fasteners onto the spindle according to the fastener used. If washers are used,

be sure they are facing in the right direction and are clean. Make sure any washers with dowels t properly into

the mating holes.

7. Install the outer spindle nut. Using a torque wrench, tighten this nut to 250-300 ft. lbs. Resulting end play should
be .001” - .005”.

Note: If end play is not .001” - .005”, disassemble and repeat this procedure.

Maintenance

Year End Maintenance

Storage

• Park Bale Skoop on level ground.

• Lock hitch in the “in-line” position with hitch safety pin.

• Set loader on the hitch.

• Relieve pressure in lines to prevent “thermal” lock.

WARNING: Keep children away from the stored Bale Skoop. Many of the surfaces on the
machine are slippery and injuries may result from climbing on or around machine.

CAUTION: Keep livestock away from machine so they will not injure themselves or damage
the machine.

Preventative Maintenance

• Paint bed with a graphite impregnated paint (Slip Plate®) to keep it from rusting.

• Touch up any scratches or aking paint.

• Grease all zerks with an all-purpose, non-clay based grease. The non-clay based grease should help eliminate
the plugging of grease zerks.

• Cover tires to prevent sun damage.

CAUTION: Direct sunlight will cause tires and hoses to deteriorate more quickly.

Storage

Preparing for Storage

• To insure longer life and satisfactory operation,
store the implement in a shed.

• If building storage is impossible, store away from

areas of main activity on level, rm, dry ground.

• Lock hitch in the “in-line” position with hitch safety
pin.

• Set loader on the hitch.

• Relieve pressure in lines to prevent “thermal” lock.

• Clean machine thoroughly.

• Inspect all parts for wear or damage.

• Avoid delays - if parts are required, order at the end
of the season.

• Lubricate grease ttings. (Refer to Maintenance

Section).

• Tighten all bolts to proper specications (Refer to

Maintenance Section).

• For a safer storage, lower the implement into eld

position and release the hydraulic pressure.

• Level implement using hitch jack and block up.

• Relieve pressure from hydraulic system.

• Raise frames, block up and relieve weight from the
tires.

• Cover tires with canvas to protect them from the
elements when stored outside.

• Coat exposed cylinder shafts (Refer to Cylinder

Shaft Protection).

• Paint bed with a graphite impregnated paint (Slip

Plate®) to keep it from rusting.

• Touch up any scratches or aking paint.

Note: Direct sunlight will cause tires and hoses to

deteriorate more quickly.

Warning

Do not allow children to play

on or around the machine.

Caution

Keep livestock away from machine so they
will not injure themselves or damage the
machine.

7-2 June 2015 HD4SR & 12SR

Cylinder Shaft Protection

The steps summarized below should be followed when
protecting chrome plated shafting on equipment:

• Position the equipment as it will be stored, and
identify all the exposed portions of the chrome plated
shafts.

• Clean dirt and dust from the exposed portions of
the shaft using a dry cloth or a cloth which has been
dampened with an appropriate solvent.

• Prepare a mixture of 60% oil-based rust inhibitor and
40% Kerosene. Apply a thin coating of this mixture
to the exposed surfaces of the chrome plated shaft.
No. 1 fuel oil may be substituted for Kerosene. A
cloth dipped in the mixture can be used to apply the
coating.

• Inspect the shaft surfaces after six months and apply
additional corrosion preventative mixture.

• If the equipment is to be moved and then stored
again for an extended period of time, the steps above
should be repeated for all shafts that were stroked
during the move.

• Before retracting the cylinders the protective
coating should be removed. This will prevent
fine sand and dirt that has accumulated in the
coating, from damaging the shaft seal. Under

no circumstances should sandpaper or other
abrasive material be used to clean the surfaces.

Plastic or copper wool in combination with an
appropriate solvent will remove most of the dirt.

Storage

Caution

Dirt in the hydraulic system could damage
O-rings, causing leakage, pressure loss and
total system failure.

Removing from Storage

• Review Operator’s Manual.

• Check tire pressure (Refer to Tire Pressure List).

• Clean machine thoroughly. Remove coating from
exposed cylinder shafts (Refer to Cylinder Shaft

Protection).

• Lubricate grease fittings (Refer to Lubricating
Section).

• Tighten all bolts to proper specications (Refer to

Bolt Torque Chart).

Manifold Valve

Troubleshooting

Troubleshooting Guide

Hydraulic System Overview

The movement of the loader on the Auto Align Bale Skoop is controlled by the Manifold Valve located under the

Bed. The Manifold consists of 5 pressure relief valves which are set to open when the uid pressure against them
reaches a designated pressure. These internal pressure relief valves are adjustable, allowing for ne-tuning of the

hydraulically actuated sequence of motions of the loader.

Troubleshooting the Hydraulics

The hydraulic systems for the Bale Skoop are fairly simple. Most problems are rooted either in mis-adjusted pressure
relief valve(s) in the manifold, or switched hoses entering the manifold.

When troubleshooting hydraulic problems always start with hose routing. Use the Hydraulic Hose Routing diagram

in the “Parts Breakdown” section to conrm the proper hose routing.

If hoses are properly routed, adjusting the pressure relief valves in the manifold should resolve the problem.

Use the Troubleshooting Chart on the next page to correlate the problem with a potential solution.

Valves and Valve Functions

Valve 2. Plug.

Valve 3. Sequence check valve causes the alignment arms to close rst

and then the loader to raise.

Valve 4. Counter balance valve which holds the loader up while the alignment

arms open.

Valve 5. Sequence valve which allows the alignment arms to close rst

before the grab hooks engage.

Valve 6. Check valve which causes the oil to ow in the right direction.

12SR Models Only

Grab Hook Valve

4-Way valve used to direct the ow of oil to the grab hook cylinder.
