Important Safety Information

Listed below are common practices that may or may not be applicable to the products described in this manual.

Tire Safety

 Tire changing can be dangerous

and must be performed by trained personnel using the correct tools and equipment.

 Always maintain correct tire

pressure. Do not inflate tires above recommended pressures shown in the Operator’s Manual.

 When inflating tires, use a clip-on

chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available.

 Securely support the attachment

when changing a wheel.

 When removing and installing

laws.

 Use towing vehicle and trailer of

adequate size and capacity. Secure equipment towed on a trailer with chocks, tie downs, and chains.

 Sudden braking can cause a towed

trailer to swerve and upset. Reduce speed if towed trailer is not equipped with brakes.

 Avoid contact with any overhead

utility lines or electrically charged conductors.

 Always drive with load on end of

loader arms low to the ground.

 Always drive straight up and down

steep inclines with heavy end of skid steer on the “uphill” side.

 Engage park brake when stopped on

an incline.

 Maximum transport speed for an

attached equipment is 20 mph. DO NOT EXCEED. Never travel at a speed which does not allow adequate control of steering and stopping. Some rough terrains require a slower speed.

 As a guideline, use the following

maximum speed weight ratios for attached equipment:

20 mph when weight of attached equipment is less than or equal to the weight of machine towing the equipment.

10 mph when weight of attached equipment exceeds weight of machine towing equipment but not more than double the weight.

 IMPORTANT: Do not tow a load that

is more than double the weight of the vehicle towing the load.

Dig Safe - Avoid Underground Utilities

 USA: Call 811

CAN: digsafecanada.ca

Always contact your local utility companies (electrical, telephone, gas, water, sewer, and others) before digging so that they may mark the location of any underground services in the area.

 Be sure to ask how close you can

work to the marks they positioned.

Practice Safe Maintenance

 Understand procedure before doing

work. Refer to the Operator’s Manual for additional information.

 Work on a level surface in a clean

dry area that is well-lit.

 Lower attachment to the ground and

follow all shutdown procedures before leaving the operator’s seat to perform maintenance.

2/6/19

Important Safety Information

These are common practices that may or may not be applicable to the products described in this manual.

Prepare for Emergencies

 Be prepared if a fire starts.  Keep a first aid kit and fire

extinguisher handy.

 Keep emergency numbers for

doctor, ambulance, hospital, and fire department near phone.

911

Wear Personal Protective Equipment (PPE)

 Wear protective clothing and

equipment appropriate for the job such as safety shoes, safety glasses, hard hat, and ear plugs.

 Clothing should fit snug without

fringes and pull strings to avoid entanglement with moving parts.

 Prolonged exposure to loud noise

can cause hearing impairment or hearing loss. Wear suitable hearing protection such as earmuffs or earplugs.

 Operating equipment safely

requires the operator’s full attention. Avoid wearing headphones while operating equipment.

Avoid High Pressure Fluids Hazard

 Escaping fluid under pressure

can penetrate the skin causing serious injury.

 Relieve all residual pressure

before disconnecting hydraulic lines or performing work on the hydraulic system.

 Make sure all hydraulic fluid

connections are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system.

 Use a piece of paper or

cardboard, NOT BODY PARTS, to check for suspected leaks.

 Wear protective gloves and

safety glasses or goggles when working with hydraulic systems.

 DO NOT DELAY. If an accident

occurs, see a doctor familiar with this type of injury immediately. Any fluid injected into the skin or eyes must be treated within a few hours or gangrene may result.

Use Safety Lights and Devices

 Slow moving tractors, skid steers,

and self-propelled machines can create a hazard when driven on public roads. They are difficult to see, especially at night. Use the Slow Moving Vehicle (SMV) sign when on public roads.

 Flashing warning lights and turn

signals are recommended whenever driving on public roads.

Use Seat Belt and ROPS

 Kubota recommends the use of a

CAB or roll-over-protectivestructures (ROPS) and seat belt in almost all power machines. Combination of a CAB or ROPS and seat belt will reduce the risk of serious injury or death if the power machine should be upset.

 If ROPS is in the locked-up

position, fasten seat belt snugly and securely to help protect against serious injury or death from falling and machine overturn.

Keep Riders Off Machinery

 Never carry riders on skid steer

or attachment.

 Riders obstruct operator’s view

and interfere with the control of the power machine.

 Riders can be struck by objects

or thrown from the equipment.

 Never use skid steer or

attachment to lift or transport riders.

AP-SC7072 Skid Cutter 326-974MK2/6/19

Table of Contents

Introduction

Kubota welcomes you to the growing family of new product owners. This Skid Cutter has been designed with care and built by skilled workers using quality materials. Proper assembly, maintenance, and safe operating practices will help you get years of satisfactory use from this product.

Application

SC7072 construction-grade Skid Cutter is designed with the commercial or high use consumer in mind. It features a rigid hitch mounting system, 1/4" thick deck, 4 swinging blades, and a bi-fold door on the front. The SC7072 is capable of cutting and shredding brush or trees up to 7" in diameter. Carbide mulching teeth mounted on the bottom of the blade carrier can be used for grinding stumps.The strong push bars on top and under the door of the SC7072 Skid Cutter allow the operator to push trees and brush over and away from the operator as they are being cut without damaging the unit. The ability to cut and mulch trees and stumps level to the ground makes this cutter ideal for clearing right-of-ways along road sides, pipelines or under electrical transmission lines with the speed and efficiency needed by today’s contractors. Farmers, ranchers and land developers will also benefit from this unit when clearing pastures or new development areas. The SC7072 Skid Cutter utilizes the power, compact size, and the go anywhere ability of a SVL to access over grown areas where a tractor and rotary cutter cannot go. The wide, full-length tapered skid shoes prevent the cutter from digging in or getting hung up in the soft ground usually found under heavy brush. Use if this skid cutter is limited to standard brush cutting. Use in significantly larger or denser brush will result in excessive heat and may damage the skid cutter or the skid steer.

Safety Information

DANGER

To avoid serious injury or death:

• Rotary Cutters have the ability to discharge objects at high

speeds; therefore, the use of front and rear safety guards is mandatory when cutting along roadways and in areas where people may be present. Stop blade rotation if a bystander is in or around the area.

• Do not use cutter as a fan. Cutting blades are not properly

designed or guarded for this use.

• Do not operate cutter with skid shoes higher than 16 1/2"

off the ground. Always use height adjusting safety chain to limit cutting height. Raising cutter too high will throw debris at the operator.

• All guards and shields must be installed and in good

working condition while operating the attachment.

• Do not operate cutter after dark without working lights.

The equipment can hit unseen objects or be hit by other vehicles. The operator can loose control of the power unit and cutter causing a wreck or roll-over.

WARNING

To avoid serious injury or death:

• Hydraulic fluid under high pressure can penetrate the skin

• Never carry riders on the attachment or power machine.

Riders can obstruct the operator’s view, interfere with control of the equipment, be pinched by moving components, become entangled in rotating components, be struck by objects, be thrown or fall from the equipment, etc.

• Do not cut on steep inclines. The power machine could flip

over causing damage to the equipment and serious bodily injury or death.

• Do not operate any hammer or mulching equipment on an

open cab machine or on a machine with a tempered front glass window/door. We strongly recommend use of a polycarbonate front glass door/window when operating any hammer or mulching equipment.

• Allow only persons to operate this implement who have

fully read and comprehended this manual, who have been properly trained in the safe operation of this implement, and who are age 16 or older. Serious injury or death can result from the inability to read, understand, and follow instructions provided in this manual.

• Do not become entangled in hydraulic hoses while entering

or exiting the skid steer operator station.

• Do not operate cutter without a polycarbonate door

mounted to the cab and protective eye wear such as safety glasses or goggles. Flying objects from the cutter can cause serious injury to the body and eyes.

• Do not abuse equipment. Incorrect use of the attachment

can damage equipment structurally and cause serious injury or death..

• Do not travel too fast. The rougher the terrain, the slower

you must travel. Always travel at a speed slow enough to be able to adjust the deck height before running it into the ground. Also, travel slow enough to stop before running or turning into obstacles ahead and on either side.

• Do not use attachment to lift, carry, push or tow other

equipment and objects. It is not properly designed or guarded for this use. The operator could lose control and cause a tipping hazard.

• Do not use attachment to pull and/or pry fence posts,

stumps, roots, rocks, or other objects out of the ground. It is not properly designed or guarded for this use.

• Do not use attachment as a lifting device for people or as a

Section 3: Operating Procedures

Table of Contents

• Do not operate cutter with blades that are out-of-balance,

bent, excessively worn, excessively nicked, or with blade bolts that are excessively worn. Such blades can break loose at high speeds.

• Do not alter attachment or replace parts on the attachment

with other brands. Other brands may not fit properly or meet OEM specifications. They can weaken the integrity and impair the safety, function, performance, and life of the attachment. Replace parts only with genuine OEM parts.

• Do not exceed rated cutting capacity of your cutter. See

specifications & capacities for specified cutting capacity. Exceeding rated cutting capacity can damage drive components, cutter blades, and deck components.

• Cutter deck can be slippery especially when wet. Always

step on anti-slip surfaces when possible. Never hurry. Make sure you have secure footing and hand hold when walking on the deck.

• Buildup of debris around moving components and

gearboxes is a fire hazard. Keep rotating parts and gearboxes free from debris to avoid serious injury and property damage.

• Avoid catching hydraulic hoses on brush, posts, tree limbs,

and other protrusions that could damage and/or break them.

• Always shut skid steer down using “Skid Steer Shut Down

Procedure” provided in this manual before dismounting to maintain and/or make adjustments to the skid steer cutter.

Cutting Instructions

IMPORTANT: Do not over angle hitch plate forward.

Over angling can cause damage to deck and hitch.

The Skid Cutter should be operated in one of three ways.

a. If cutting grass, weeds, or light brush operate with

the deck rear slightly higher than deck front.

b. If cutting heavy brush, operate with the deck front

3" to 5" higher that the deck rear for the length of the cutter. Lower the deck front and backup slowly mulching the debris and leveling brush root spike to ground level.

c. If cutting and mulching trees, operate by raising

deck front 12" to 15" higher than deck rear. Cut the tree so that it falls away from the operator. Upon tree falling, back up, then lower the deck front 6", drive forward to remove stump, back up, lower deck front to the ground, drive forward to mulch the stump to ground level. Lift deck front 12" to 15" and repeat steps above to mulch the fallen tree.

IMPORTANT: Do not lower operating mulcher down onto trees, saplings or bushes that are 12" tall.

NOTE: Your cutter is equipped with free swinging cutting blades to reduce shock loads to the cutter when striking an obstacle.

1. Thoroughly inspect the area to be cut for debris and unforeseen objects. Mark any potential hazards.

2. Set skid steer hydraulic lift arms and hitch angle to position the deck front at the preferred cutting height and the deck rear slightly higher.

3. Start the skid steer and engage hydraulic motor. Allow several seconds for cutter blades to become aligned properly. If deck continues to vibrate after several seconds, stop motor and inspect blades.

4. It is important to maintain correct hydraulic motor speed. Loss of motor speed will allow the blades to hinge back and result in ragged, uneven cutting.

5. Ground speed depends on two things: the density of material being cut and size of skid steer. Never run fast enough to overload the skid steer or cutter.

6. This cutter was designed to cut brush and small trees on gently sloping or slightly contoured right-of-ways, pastures, set aside acres, and row crop fields.

Transporting

WARNING

To avoid serious injury or death:

When traveling on roadways, travel in such a way that other vehicles may pass you safely. Use LED lights, clean reflectors, and a slow moving vehicle sign that is visible from the back to warn operators in other vehicles of your presence. Always comply with all federal, state, and local laws.

1. Be sure to reduce ground speed when turning; and, leave enough clearance so the Skid Cutter does not contact obstacles such as buildings, trees, or fences.

2. Select a safe ground travel speed when transporting from one area to another. When traveling on roadways, transport in such a way that faster moving vehicles may pass you safely.

3. Decrease transport speed when traveling over rough or hilly terrain.

4. When transporting skid steer and Skid Cutter on a trailer:

• Use towing vehicle and trailer of adequate

capacity.

• Always drive up a ramp with heavy end uphill.

• Engage skid steer park brake and remove ignition

switch key once it is loaded.

• Secure skid steer loader and attachment using tie-

downs and chains.

Skid Steer Shutdown Procedures

The following are basic skid steer shutdown procedures. Follow these procedures and any additional shutdown procedures provided in your skid steer Operator’s Manual before leaving the operator’s seat.

1. Reduce engine speed and shut-off all power to the attachment.

2. Park on solid, level ground and lower attachment until it is flat on the ground or on solid (non-concrete) support blocks.

3. Turn off engine, and remove switch key to prevent unauthorized starting.

4. Relieve all hydraulic pressure to auxiliary hydraulic lines.

5. If included, raise seat bar and move controls until both lock.

6. Wait for all components to come to a complete stop before leaving the operator’s seat.

7. Use steps, grab-handles and anti-slip surfaces when stepping on and off the skid steer or attachment.

General Operating Instructions

It is absolutely essential that you read and understand both the Operator’s Manual for your Kubota Skid Cutter and the Operator’s Manual for the skid steer unit you intend to attach it to before attempting to operate or cut with this combination of equipment. You must be able to read, comprehend, and adhere to all safety warnings and decals in order to avoid personal injury, fatalities, injury to others, or costly damage to property and equipment. We highly recommend that you be a skilled and competent skid steer operator prior to attaching and attempting to use the Skid Cutter. If there is any part of the information above or safe operating procedures you do not understand, please contact your nearest authorized dealer for a full explanation and training session if necessary.

If attachment is to be operated in reverse, make sure visibility to the rear of the power unit is appropriate for the attachment. Backup camera or mirror is recommended. Maintain cleanliness of lens or mirror.

Skid Steer Operating Instructions

WARNING

To avoid serious injury or death:

Do not operate any hammer or mulching equipment on an open cab machine or on a machine with a tempered front glass window/door. We strongly recommend use of a polycarbonate front glass door/window when operating any hammer or mulching equipment.

Assuming you have met all of the requirements and taken them seriously, it is time to take the next step and that is accomplished by dressing appropriately for the task. You will need to put on protective eye wear such as safety glasses, goggles, or a face shield. A hard hat, steel toed safety shoes, gloves, and hearing protection are also highly recommended. Never wear loose fitting clothing. A respirator or filter mask will help reduce the amount of dust, pollen, or agricultural chemicals potentially inhaled by the operator.

The next step is a static or non-running pre-inspection of the skid steer unit. You will want to make sure that the skid steer is equipped with a fully functioning ROPS (Roll Over Protective Structure) which does include seat belts and an operator safety enclosure. The cab must also be equipped with a polycarbonate door, which may have been supplied with the skid steer unit. If the skid steer is to be operated on local roadways, it must be equipped with appropriate Slow Moving Vehicle (SMV) and other required lighting packages so as to make it compliant with federal, state and local department of transportation requirements. The cutter drive motor must be matched to the output of the hydraulic capacity of the skid steer. Failure to do this could result in serious over-speeding of the cutting unit possibly resulting in serious injury, fatalities, or property damage. The universal quick-hitch mount should be in good working order and latches should be located to the open position. There should be no evidence of hydraulic leaks in and around the auxiliary hydraulic couplers. There must be a readily accessible attaching point for the Skid Cutter lift-limit chain on the lower front portion of the chassis frame. Finally make sure that all shields and safety features are in place and fully functional.

The next step is to perform a running check of the skid steer unit. As you get onto the skid steer and into the operator’ compartment always use factory provided hand-holds to ease or stabilize your entry. Fasten your seat belt once you are seated and begin to mentally orient yourself with the position of all controls, switches, pedals, levers, and their related functions. Once you are sure that the park brake is on, no people or animals are in close proximity, all control levers, pedals, and hydraulic systems are in neutral position, go ahead and start the engine. With the engine now running and the throttle at approximately one third, test all controls to make sure they are fully functioning. If at any time there is an equipment failure, shut the unit down and make immediate and full repairs.

Section 3: Operating Procedures

Table of Contents

For additional information, review the operator’s manual for your skid steer along with the manufacturers recommended checks before operation.

Skid Cutter Operating Instructions

Once all systems with the skid steer are “go” and fully functioning, it is time to connect to your SC7072. This is done by maneuvering the skid steer mounting plate into position under the universal quick hitch top angle bar. Once this is accomplished and the mower is fully supported by the skid steer lift arms, lower mower to a point approximately two inches above ground. Turn the engine off, set the park brake, and climb out of the skid steer. Lock the latch handles down to engage the hitch pins. Connect the hydraulic hoses to the appropriate auxiliary hydraulic outlets and case drain making sure to keep connectors clean. (Note: Hydraulic flow direction on all skid steers is not the same. Make sure hoses are connected properly or blades will rotate at a much slower speed.) Connect the height limiting safety chain to the chassis attaching point and restrict cutting height to no more that eighteen inches. This completes the attachment of the cutter to the skid steer.

The next step is to complete a pre-operation check of the cutter. Make sure all guards, safety shields, safety chains, and deflectors are in place. All hardware must be in place and appropriately tightened. Damaged, severely worn, or defective parts must be replaced prior to operation.

You should always inspect the area you intend to cut for debris and hazards located on the ground. No one, including people and animals, should be allowed within 100 yards of this cutter when in operation. If someone does approach, shut the cutter down immediately. The blades on this cutter should never be allowed to come in contact with objects such as wire, cable, rope, or chains that might become entangled. These types of entangled objects can become extremely hazardous by rotating outside of the cutter deck housing resulting in serious injury or death. Always inspect the area before you mow.

The best mowing results will be achieved at speeds up to 2 mph or as vegetation and ground conditions dictate. If you are mowing in particularly tall or dense brush, you may want to make two passes with the first pass being higher and the second pass made as a cross-cut at the desired cut height. The pressure gauge option enables the operator to determine the ground speed obtainable without stalling the cutter pressure gauge the pressure reading should be up to within 500 PSI of the skid steer’s output. Example: skid steer output = 3500 PSI, if the operator adjusts the ground speed so the pressure gauge reading is up to 3000 PSI then the cutter will not stall. If the ground speed causes the pressure to increase to 3500 PSI the cutter will stall and the blades will stop rotating. Conversely, if the pressure reading is less than 3000 PSI, the operator can increase their ground speed if desired. Driving too fast over uneven ground will cause the unit to undulate in a forward pitching motion. Only increase the ground speed when you are comfortable with how the complete system responds in various terrain.

The Skid Cutter should be operated in one of three ways.

1. If cutting grass, weeds, or light brush operate with the deck rear slightly higher than deck front.

2. If cutting heavy brush, operate with the deck front 3" to 5" higher that the deck rear for the length of the cutter. Lower the deck front and backup slowly mulching the debris and leveling brush root spike to ground level.

3. If cutting and mulching trees, operate by raising deck front 12" to 15" higher than deck rear. Cut the tree so that it falls away from the operator. Upon tree falling, back up, then lower the deck front 6", drive forward to remove stump, back up, lower deck front to the ground, drive forward to mulch the stump to ground level. Lift deck front 12" to 15" and repeat the steps above to mulch the fallen tree.

IMPORTANT: Use of this Skid Cutter is limited to standard brush cutting. Use in significantly larger or denser brush will result in excessive heat and may damage the Skid Cutter or the skid steer.

. When operating with a

When you do need to stop, make sure you set the park brake, shut the skid steer engine off, and allow time for the blades to stop rotating before you exit the power unit. With a little practice we are confident you will soon achieve safe and excellent results with your new Kubota SC7072 Skid Cutter.

Section 5: Maintenance & Lubrication

Maintenance

Proper servicing and adjustment are key to the long life of any attachment. With careful inspection and routine maintenance, you can avoid costly downtime and repair.

Check all bolts after using unit for several hours to be sure they are tight. Replace any worn, damaged, or illegible safety labels by obtaining new labels from your Kubota dealer.

The parts on your cutter have been specially designed and should only be replaced with genuine Kubota parts. Do not alter the cutter in a way which will adversely affect its performance.

DANGER

To avoid serious injury or death:

Always secure equipment with solid, non-concrete supports before working under it. Never go under equipment supported by concrete blocks or hydraulics. Concrete can break, hydraulic lines can burst, and/or hydraulic controls can be actuated even when power to hydraulics is off.

Hydraulic Maintenance

WARNING

To avoid serious injury or death:

Hydraulic fluid under high pressure can penetrate the skin and/or eyes causing a serious injury. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. Use a piece of cardboard or wood rather than hands when searching for leaks. A doctor familiar with this type of injury must treat the injury within a few hours or gangrene may result. DO NOT DELAY.

One of the most important things you can do to prevent hydraulic system problems is to ensure that your skid steer reservoir remains free of dirt and contamination.

Use a clean cloth to wipe the hose ends before attaching them to your skid steer. Replace the filter element for your skid steer’s hydraulic system at the prescribed intervals. These simple maintenances will go a long way to prevent occurrence of hydraulic problems.

WARNING

To avoid serious injury or death:

• Do not alter attachment or replace parts on the attachment

• Buildup of debris around moving components and

gearboxes is a fire hazard. Keep rotating parts and gearboxes free from debris to avoid serious injury and property damage.

• Backup alarm must be in good working order to warn

others. Use a backup camera or rear-view mirror that is in good condition to help see undesirable situations behind the unit. Drive at a slower speed to compensate for blind spots.

Cutter Blade Maintenance

WARNING

To avoid serious injury or death:

• Always shut power machine down using the “Shutdown

Procedure” provided in this manual before servicing, adjusting, cleaning, or maintaining the attachment.

• Do not operate cutter with blades that are out-of-balance,

bent, excessively worn, excessively nicked, or with blade bolts that are excessively worn. Such blades can break loose at high speeds.

IMPORTANT: Replace blades in sets with genuine OEM blades only. It is highly recommended to replace blades in sets. Not replacing blades in sets will result in an out-of-balance condition that could contribute to premature bearing wear/breakage and/ or structural cracks in gearbox and/or deck.

Always inspect blades before each use. Make certain they are properly installed and in good working condition. Blades that are damaged, worn, bent, or excessively nicked should be replaced. Never try to straighten a bent blade! Small nicks can be ground out when sharpening.

Remove cutting blades and sharpen or replace as follows:

1. Properly shut down skid steer according to your skid steer Operator’s Manual.

2. Secure cutter deck in a raised position with solid supports before servicing underside of cutter.

5. Unscrew three 3/4" hex nuts (#1) to remove cutting blade (#4) and blade retainer (#3).

6. Blades should be sharpened at the same angle as the original cutting edge and must be replaced or reground at the same time to maintain proper balance in the cutting unit. The following precautions should be taken when sharpening blades:

IMPORTANT: The blades are double edged and can be flipped over and re-used after one side gets worn. The blades must be assembled as shown in Figure 5-2 alternating one blade right side up and the next upside down to achieve optimal cut.

a. Do not remove more material than necessary.

b. Do not heat and pound out a cutting edge.

c. Do not grind blades to a razor edge. Leave a blunt

cutting edge approximately 1/16" thick.

d. Always grind cutting edge so end of blade remains

square to cutting edge and not rounded.

e. Blades should weigh the same with not more than

1 1/2 oz. difference. Unbalanced blades will cause excessive vibration which can damage gearbox bearings and create structural cracks.

Refer to Figure 5-2:

IMPORTANT: Examine bolts, washers, and nuts for excessive wear and replace if worn.

7. Insert three 3/4-10X2 3/4 GR8 bolts (#5) through the blade carrier bottom (#10), blade retainer (#3) and cutter blade (#4), the blade carrier top (#9) and lock washers (#2). Secure with three 3/4" hex nuts (#1).

Skid Shoe Maintenance

WARNING

To avoid serious injury or death:

Excessive wear on skid shoes can damage side panels, cause inadequate operation of cutter, and create a safety hazard. Always replace skid shoes at the first sign of wearing thin.

Skid shoes should be inspected at the beginning of each cutting season and replaced when material thickness is less than 1/8" at any point or if other damage is evident. Order only genuine Kubota parts from your local Kubota dealer.

Refer to Figure 5-3:

Replace skid shoes as follows:

1. Raise the Skid Cutter 3" or more off the ground and place solid (non-concrete) support blocks under the cutter. Make sure the solid (non-concrete) support blocks are positioned so they will not interfere with skid shoe installation.

2. Lower cutter onto solid (non-concrete) support blocks, place skid steer in park, set park brake, shut the skid steer off and remove switch key.

3. Remove 3/8" hex nuts (#3), lock washers (#4), flat washers (#5), 3/8" plow bolts (#2) and two skid shoes (#1 & 6) from each side of the deck.

4. Plow bolts (#2) should be checked for wear and replaced if necessary.

5. Install the new skid shoes (#1 & 6) to one side of the deck as shown with 3/8"-16 GR5 plow bolts (#2), flat washers (#5), lock washers (#4) and 3/8" hex nuts (#3). Tighten nuts to correct torque.

6. Repeat step 5 for other side of the deck.

7. Raise cutter up and remove from solid (nonconcrete) support blocks.

Long-Term Storage

Clean, inspect, service, and make necessary repairs to the SC7072 when storing it for long periods and at the end of the season. This will help to ensure the unit is ready for field use the next time you hook-up to it.

To avoid serious injury or death:

DANGER

WARNING

• Always shut power machine down following the “Shutdown

Procedure” provided in this manual before leaving the operator’s seat.

• Do not alter attachment or replace parts on the attachment

Clean the Skid Cutter at the end of the working season or when the cutter will not be used for a long period.

1. Clean off any dirt or grease that may have accumulated on the cutter and moving parts. Scrape off compacted dirt from the bottom of the deck and then wash the surface thoroughly with a garden hose. A coating of oil may also be applied to the lower deck area to minimize oxidation.

2. Check blades, carbide teeth and hardware for wear and replace if necessary. See “Cutter Blade

Maintenance” on page 20 and “Carbide Teeth Maintenance” on page 21.

3. Inspect for loose, damaged, or worn parts and adjust or replace as needed.

4. Repaint parts where paint is worn or scratched to prevent rust.

5. Replace all damaged or missing decals.

6. Lubricate as noted in the Lubrication portion of this section starting on page 24.

7. Store the Skid Cutter in a clean, dry place. The deck should be positioned on a flat surface to suitable skid steer hook-up height. Ensure that the main frame is stable.
