SAFETY General Safety Instructions and Practices SAFETY A safe and careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions. The first section of this manual includes a list of Safety Messages that, if followed, will help protect the operator and bystanders from injury or death.
SAFETY The rotating parts of this machine continue to rotate even after the PTO has been turned off. The operator should remain in his seat for 60 seconds after the brake has been set, the PTO disengaged, the tractor turned off, and all evidence of rotation has ceased. (S3PT-10) “Wait a minute...Save a life!” Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch. Release of the control lever or mechanical failure will result in the Implement falling and possible injury or death.
SAFETY Always read carefully and comply fully with the manufacturers instructions when handling oil, solvents, cleansers, and any other chemical agent. (SG-22) SAFETY KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement and possible serious injury or death. (SG-24) Never allow children to play on or around Tractor or Implement. Children can slip or fall off the Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing themselves or others.
SAFETY DO NOT operate this Implement on a Tractor that is not properly maintained. Should a mechanical or Tractor control failure occur while operating, immediately shut down the Tractor and perform repairs before resuming operation. Serious injury and possible death could occur from not maintaining this Implement and Tractor in good operating condition. Equipment Operation Safety Instructions and Practices Use extreme care when lowering or unfolding the implement’s wings.
SAFETY Flail Mowers are capable under adverse conditions of throwing objects for great distances (100 yards or more) and causing serious injury or death. Follow safety messages carefully.
SAFETY Never allow children to operate, ride on, or come close to the Tractor or Implement. Usually, 16-17 year-old children who are mature and responsible can operate the implement with adult supervision, if they have read and understand the Operator’s Manuals, been trained in safe operation of the tractor and Implement, and are physically large enough to reach and operate the controls easily. (SG-11) Do not mount the Tractor while the tractor is moving.
SAFETY SAFETY In case of mechincal difficulty during operation, place the transmission in the park position, set the parking brake, shut down all power, including the PTO and the engine and remove the key. Wait until all rotating motion has stop before dismounting. (SG-39) Do Not operate this equipment in areas where insects such as bees may attack you and/or cause you to lose control of the equipment.
SAFETY Avoid mowing in reverse direction when possible. Check to make sure there are no persons behind the mower and use extreme care when mowing in reverse. Mow only at a slow ground speed where you can safely operate and control the tractor and mower. Never mow an area that you have not inspected and removed debris or foreign material. (SGM-8) Do not mow with two machines in the same area except with Cab tractors with the windows closed.
SAFETY DO NOT allow any person under a folded wing unless wing is securely locked up or supported. DO NOT approach the Implement unless the Tractor is turned off and all motion has ceased. Never work under the frame work, or any lifted component unless the implement is securely supported or blocked up. A sudden or inadvertent fall by any of these components could cause serious injury or even death.
SAFETY Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills only at a low speed and using a gradual steering angle. Rear mounted implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over.
SAFETY Transport only at safe speeds. Serious accidents and injuries can result from operating this equipment at unsafe speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly. SAFETY Before transporting the Tractor and Implement, determine the safe transport speeds for you and the equipment.
SAFETY Secure the Implement for transport before traveling on public roads. For pull-type Implements, secure the center axle using cylinder stops or transport pin and properly attach a safety chain between the Implement and Tractor. Secure wings in upright position on folding Implements using wing transport locks. (STI-7) Maintenance and Service Safety Instructions and Practices Make sure the PTO shield, integral driveline shields, and input shields are is installed when using PTO-driven equipment.
SAFETY Never attempt to lubricate, adjust, or remove material from the Implement while it is in motion or while tractor engine is running. Make sure the tractor engine is off before working on the Implement. (SG-20) SAFETY Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins have cotter pins and washers.
SAFETY Always disconnect the main PTO Driveline from the Tractor before performing service on the Mower. Never work on the Mower with the tractor PTO driveline connected and running. Blades or Drivelines could turn without warning and cause immediate entanglement, injury or death. (SRM-3) Wear gloves and exercise care when handling blades. Blades are SHARP and can cause lacerations to hands and other parts of the body if not safely handled.

A qualified operator has read and understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor operation and all associated safety practices. In addition to the safety messages contained in this manual, safety decals are affixed to the implement and tractor.
OPERATION The tractor used to operate the mower must have the power, capacity and required equipment to safely operate the mower at a ground speed between 2 and 5 MPH. Operating the mower with a tractor that does not meet the following requirements may cause tractor or mower damage and could be a potential danger to the operator and passersby. Tractor Requirements and Capabilities • • • • • 2.
OPERATION 2.3 Tractor Horsepower The horsepower required to operate the mower depends on many factors including the vegetation to be cut, terrain condition, operator experience, and condition of the mower and tractor. For most mowing condition, the RC12 requires a tractor with at least 90 HP. Operating the mower with a tractor that does have adequate power may damage the tractor engine. OPERATION 2.4 3-Point Hitch Lift Type RC Flails should be coupled with a quick hitch only.
OPERATION If operating an older model tractor where the tractor’s transmission and PTO utilize on master clutch, an overrunning clutch must be used between the PTO output shaft and the driveline of the mower. Consult an authorized tractor dealer to purchase and install an over-running clutch if needed. Never operate the Tractor and Mower if the Implement input driveline is directly connected to the Tractor transmission.
OPERATION Never allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death. (SG-10) OPERATION Do not mount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped. (SG-12) 3.
OPERATION 4. STARTING THE TRACTOR The operator must have a complete understanding of the placement, function, and operational use of all tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized dealer for tractor operation instructions if needed. Essential Tractor Controls: • Conduct all pre-start operation inspection and service according to the tractor operator’s manual. • Make sure all guards, shields, and other safety devices are securely in place.
OPERATION Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches. (S3PT-15) OPERATION 6. SETTING THE MOWER Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven terrain.
OPERATION The mower’s cutting height is set by positioning the roller assembly for each mower section. Each section must be set at the same height to ensure an even cut across the entire width of the mower. Place the tractor and mower on a level surface and completely lower the mower to the ground. 2. Shut down the tractor, place the transmission in park, and set the parking brake before dismounting. 3.
OPERATION 6.1 Leveling Deck OPERATION To Facilitate a safe and efficient mowing operation, the mower should be operated parallel to the ground at all times. Never operate if front or rear of mower is tilted upward. Objects may be discharged at high speeds causing possible injury or even death. Adjust Top Link to level mower roller adjustment. Side Skid Shoes should always be parallel to ground throughout the full adjustment range.
OPERATION Before operating the Implement, check to make sure the Implement input driveline will not bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and through the support bearings or downward onto the PTO shaft, breaking it off. A broken drive line can cause personal injury.
OPERATION Shorten the driveline profiles as follows: • • OPERATION • • • • • Remove the driveline from the tractor. Position the mower to the point with the shortest distance between the tractor PTO shaft and cutter gearbox. Shut down the tractor and securely block the mower in this position. Pull driveline apart and reattach yoke to PTO shaft. Hold driveline sections parallel to one another and measure back 1” from yoke of each shaft and place mark on opposite section. Cut this length off with a saw.
OPERATION Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins have cotter pins and washers. Serious injury may occur from not maintaining this machine in good working order. (SG-21) Refer to the tractor operator’s manual to ensure a complete pre-operation inspection and scheduled service is performed according to the manufacturers recommendations.
OPERATION OPERATION All Safety Shields, Guards and Safety devices including (but not limited to) the Deflectors, Steel Guards, Gearbox Shields, PTO integral shields , and Retractable Door Shields should be used and maintained in good working condition. All safety devices should be inspected carefully at least daily for missing or broken components. Missing, broken, or worn items must be replaced at once to reduce the possibility of injury or death from thrown objects, entanglement, or blade contact.
OPERATION • • • • • • • • Inspect the condition of the drive belts. Ensure the slip clutch (rear mower section only) is properly adjusted and the friction plates are not frozen together. Reference the Maintenance Section for proper slip clutch maintenance. Ensure the slop clutch shield and drive belts shields are in place and in good repair. Ensure the tractor PTO master shield is in place, lowered and in good condition. OPS-F- 0016 .Inspect oil level in gearbox and replenish if needed.
OPERATION • • OPERATION • Inspect cutter knives and knife pins for looseness and excessive wear. Make sure the mower is securely blocked up before crawling beneath. Replace damaged, worn, and missing knives as complete sets to maintain cuttershaft balance. Remove any grass or other debris which may be wrapped around the cuttershafts. Inspect the condition of deck skid shoes and hardware. OPS-F- 0007 9.
OPERATION Transport only at safe speeds. Serious accidents and injuries can result from operating this equipment at unsafe speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly. Before transporting the Tractor and Implement, determine the safe transport speeds for you and the equipment.
OPERATION OPERATION 9.2 Brake and Differential Lock Setting Make sure the tractor brakes are in good operating condition. Tractor brakes can be set to operate independently allowing single rear wheel braking action or locked together to provide simultaneous rear wheel braking. FOR MOST DRIVING AND OPERATING CONDITIONS, THE BRAKE PEDALS SHOULD BE LOCKED TOGETHER TO PROVIDE THE MOST EFFECTIVE BRAKING ACTION. Always disengage the tractor differential lock when turning.
OPERATION 9.4 Driving the Tractor and Mower Start off driving at a slow speed and gradually increase your speed while maintaining control of the tractor and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent the operator from stopping quickly during an emergency.
OPERATION Lift-type units - Do not disengage PTO at end of row. Reduce speed and lower RPM. Raise 3-Point lift and proceed with turn. Only raise machine sufficiently to clear from turn. High loads are placed on U-Joints when shredder is raised at steep angles causing premature wear and driveline failure. Raise RPM slowly and bring machine up to speed before entering cut. OPERATION Optimum speed should be maintained while shredding.
OPERATION When confronted with an incline or ditch, do not approach from an angle which is perpendicular or straight on as damage to over collapse of the driveline may occur. When crossing such terrain, the wings should be fully lowered for a lower center of gravity and added stability. OPS-R-0021 When operating the tractor and mower across slopes and inclines, through ditches, and other uneven terrain conditions, it is important to maintain sufficient deck to ground clearance.
OPERATION OPERATION Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign objects should be removed from the site to prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing immediately if blades strike a foreign object.
OPERATION 10.1 Foreign Debris Hazards Before mowing, inspect the area to make sure there are no foreign objects that the mower blades could hit or become entangled with. Remove all foreign objects and debris. If objects are too big to remove, mark them clearly and be sure to prevent the mower blades from contacting them. Always wear your seat belt securely fastened and only operate the tractor and mower with the ROPS in the raised position.
OPERATION Flail Mowers are capable under adverse conditions of throwing objects for great distances (100 yards or more) and causing serious injury or death. Follow safety messages carefully.
OPERATION 10.4 PTO RPM and Ground Speed Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Recommended speed for efficient mower performance is between 2 and 5 mph. Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground speed.
OPERATION OPERATION Do not mow with two machines in the same area except with Cab tractors with the windows closed. (SGM-11) Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least 100 yards in front and to the sides of the tractor and mower.
OPERATION 10.6 Shutting Down the Implement To shut down the implement, first bring the tractor to a complete stop. Then slow down the implement by reducing the engine speed before disengaging the PTO. Wait for all motion to stop before proceeding to drive or shut down the tractor. RC12 12/05 © 2005 Alamo Group Inc.
OPERATION OPERATION 11. DISCONNECTING THE MOWER FROM THE TRACTOR Before disconnecting the mower, the PTO must be disengaged and all motion at a complete stop. Move the mower to a level storage location and lower to the ground. If the mower is not resting securely on the ground, block the mower up securely before attempting to disconnect it from the tractor. Use extreme care to keep feet and hands from under the mower and clear of any pinch points.
OPERATION Never stand or allow another person to stand between a running Tractor and the Mower when disconnecting the Implement from the Tractor 3-point hitch. Always shut the Tractor off completely and set the parking brake before attempting to disconnect the Mower pins from the Tractor hitch. 12. MOWER STORAGE Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service.
OPERATION OPERATION Before transporting the tractor and mower, idle the tractor engine, disengage the PTO and wait for all mower moving parts to come to a complete stop. Raise the mower sections and ensure transport locks engage. OPS-F- 0021 Before transporting the tractor on a public roadway or boarding a trailer for transport, the tractor brake pedals should be locked together. Locking the pedals ensures that both wheels brake simultaneously while stopping, especially when making an emergency stop.
OPERATION 13.1 Transporting on Public Roadways Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor must be equipped with all required safety warning features including a SMV emblem and flashing warning lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
OPERATION OPERATION Make sure that all tractor flashing warning lights, headlights, and brake/tail lights are functioning properly before proceeding onto public roads. While newer model tractors have plenty of lighting to provide warning signals and operating lighting, most older models are only equipped with operating lights. Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models.
OPERATION 13.2 Hauling the Tractor and Implement Before transporting a loaded tractor and implement, measure the height and width dimensions and gross weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the areas that will be traveled through. OPS-U- 0024 Arrange the chains so that when tightened, the chains are pulling downward and against themselves.
OPERATION OPERATION TROUBLE SHOOTING GUIDE Problem Possible Cause Remedy Excessive Vibrations Check gearbox bolts. Check for missing knives on cutter shaft. Check to see if knives are free swinging.

MAINTENANCE MAINTENANCE MAINTENANCE SECTION RC12 12/05 © 2004 Alamo Group Inc.
MAINTENANCE GENERAL MAINTENANCE Before doing any maintenance or adjusting on the mower always stop the tractor, place in park, remove the ignition key, and wait for all mower rotation to stop. Place adequate support bracing as need to safely work on the mower. In the day operation of the RC12 the operator should: MAINTENANCE Check for and tightened any loose bolts and shields. Lubricate all fittings every 8 hrs. See Lubrication. Periodically check fluid level in gearbox. See Lubrication.
MAINTENANCE MAINTENANCE To lubricate telescoping section of driveline, disconnect yoke from tractor and compress driveline until both slots on shields are aligned and grease fitting is exposed. Lubricate both u-joints before re-attaching to tractor. Inspect shields to ensure they rotate freely, replace bearings or shield if damaged. ROUTINE MAINTENANCE: Inspect belt drive for correct tension and remove any debris from inside belt shields. Incorrect tension will result in premature belt failure.
MAINTENANCE CUTTER SHAFT Routinely inspect cutter shaft for and replace any worn or damaged blades. When replacing worn blades always replace blade set directly opposite, (180 degrees) otherwise cutter shaft will be out of balance. Inspect bushing and bolt for wear and replace if necessary. Remove any debris which may become entangled around cutter shaft or bearings. Stop machine at first sign of excessive vibration and inspect cutter shaft and bearings.
MAINTENANCE PULLEY ALIGNMENT AND REMOVAL Pulleys will remain aligned during belt tension if inside pivot mount bolts (item 3) have not been loosened. Check alignment of pulleys by placing a straight edge along flat face of both pulleys. Check alignment at lower and upper end of pulley face when belt is tensioned. To relocate pulleys on drive and cuttershaft, first loosen belt tension and check for shaft movement to ensure they are not loose or have moved.
MAINTENANCE MAINTENANCE Never hammer edge of pulley which may crack. To move assembly, a soft blow hammer may be used on bushing only. If the pulley is free and the bushing is still tight on shaft, it may be necessary to wedge a screwdriver in saw slot of bushing to loosen and move hub. Do not apply excessive force which may split bushing. Never apply lubrication to threads or mating surfaces when assembling pulley and bushing.
MAINTENANCE CUTTER SHAFT AND BEARING REMOVAL Cutter Shaft Bearing Removal - Mnt-FL-0041 INSTALLATION: Clean all debris from shaft. Attach bearing (1) to bearing plate (2) using four 5/8" bolts (3) and locknuts (4). Slide assembly over shaft and align set screws with dimples in shaft. Install lock collar and apply thread locking compound to set screws and tighten in place. Attach bearing assembly and plate with outer four 5/8" bolts. Install belt as outline in Maintenance 5-6.

MAINTENANCE STORING THE RC12 • When storing the RC12 for an extended period of time, or at the end of a season, lubricate all bearings with enough grease to eliminate any cavities where water condensation may occur and cause damage. Refer to "Lubrication" for location of all grease fitting. Be sure the vent on top of the Gearbox is open. • Loosen the Set Nut and Spindle Jack to relieve drive belt tension. NOTE: Before next season's use be sure to adjust the drive belt tension.
