SAFETY General Safety Instructions and Practices SAFETY A 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 Engine Exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the state of California to cause cancer and birth defects or other reproductive harm. (SG-30) Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer, birth defects or other reproductive harm.
SAFETY 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. (SG-25) SAFETY NEVER use drugs or alcohol immediately before or while operating the Tractor and Implement. Drugs and alcohol will affect an operator’s alertness and coordination and therefore affect the operator’s ability to operate the equipment safely.
SAFETY The rotating parts of this machine continue to rotate even after the Tractor 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. (SBM-5) “Wait a minute...Save a life!” Do not put hands or feet under mower decks. Blade Contact can result in serious injury or even death. Stay away until all motion has stopped and the decks are securely blocked up.
SAFETY Equipment Operation Safety Instructions and Practices Never leave the Tractor and Implement unattended while the Implement is in the lifted position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure support under the A-Frame. Lower the implement carefully to the ground.
SAFETY Do not back up this implement when the boom or mower head is extended. Backing could damage the machine or its components. (SBM-19) Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor engine. Inspect the Mower to determine the source of the vibration. If Mower blades are missing or damaged replace them immediately. Do not operate the mower until the blades have been replaced and the Mower operates smoothly.
SAFETY Flail Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.
SAFETY Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped. (SG-12) Start tractor only when properly seated in the Tractor seat. Starting a tractor in gear can result in injury or death. Read the Tractor operators manual for proper starting instructions. (SG-13) Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health.
SAFETY 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. If you must enter in such areas, use a tractor with an enclosed Cab and close the windows to prevent insects from entering. If a tractor cab is not available, wear suitable clothing including head, face, and hand protection to shield you from the insects.
SAFETY Mow at the speed that you can safely operate and control the tractor and mower. The correct mowing speed depends on terrain condition and grass type, density, and height of cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided.
SAFETY Do not let the Blades turn when the Mower Deck is raised for any reason, including clearance or for turning. Raising the Mower deck exposes the Cutting Blades which creates a potentially serious hazard and could cause serious injury or even death from objects thrown from the Blades. (SRM-07) Maintenance and Service Safety Instructions and Practices SAFETY Make sure the PTO shield, integral driveline shields, and input shields are installed when using PTO-driven equipment.
SAFETY Always maintain the safety signs in good readable condition. If the safety signs are missing, damaged, or unreadable, obtain and install replacement safety signs immediately. (SG-5) Do not modify or alter this Implement. Do not permit anyone to modify or alter this Implement, any of its components or any Implement function. (SG-8) Never attempt to lubricate, adjust, or remove material from the Implement while it is in motion or while tractor engine is running.
SAFETY Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN, WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY CAUSE SERIOUS INJURY FROM THROWN BLADES. (SGM-10) SAFETY DO NOT weld or repair rotating mower components. Welds and other repairs may cause severe vibration and/or component failure resulting in part being thrown from the mower causing serious bodily injury.
SAFETY When transporting Boom Mower on a truck or trailer, the height or width may exceed legal limits when the boom is in the transport position. Contact with side or overhead structures or power lines can cause property damage or serious injury or death. If necessary lower boom to reduce height and/or remove mowing head to reduce width to the legal limits. (SBM-8) Secure the boom and mower head in the transport position before traveling on public roads.
SAFETY Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this equipment at high 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 proper transport speeds for you and the equipment.

ASSEMBLY TRACTOR SELECTION MINIMUM TRACTOR WEIGHT - including ballast weight if necessary: 7,750 lbs. MINIMUM HP REQUIREMENTS: 65 HP LINKAGE: ASSEMBLY Category 2 P.T.O. SHAFT: Tractor must be equipped with a live drive PTO to enable forward motion to be stopped while the flail head continues to operate. CHECK CHAINS/STABILIZERS: Check chains or stabilizers must be fitted and tightened.
ASSEMBLY TRACTOR PREPARATION Fitting Operator Guard Use tractor with safety glass windows if possible and fit Operator guard using the hooks provided. Shape mesh to cover all vulnerable areas. Remember the driver must be looking through mesh and/or poly carbonate glazing when viewing the flail head in any working position - unless the tractor/cab manufacturer can demonstrate that the penetration resistance is equivalent to, or higher than, that provided by mesh/poly carbonate glazing.
ASSEMBLY Suggestions to increase stability: ASSEMBLY • • Increasing rear wheel track; a tractor with a wider wheel track is more stable. Ballasting the wheel; it is preferable to use external weights but liquid can be added to around 75% of the tire volume – water with anti-freeze or the heavier Calcium Chloride alternative can be used. • Addition of weights – care should be taken in selecting the location of the weights to • ensure they are added to a position that offers the greatest advantage.
ASSEMBLY ATTACHMENT TO TRACTOR Reverse tractor squarely up to the machine. • Connect the tractors draft links - selecting the rear most hole in the machines lower link brackets that allow the machine to be mounted without contacting the tractor. • Ensure that the same hole is used on both sides. • If necessary fit the spacers supplied (as required) to minimise sideways movement of the tractor draft links within the hitch brackets. • Tighten tractor’s stabilizers.
ASSEMBLY .Fit the machine to top link (Optional Top Link available). • Raise machine on tractor linkage until the tractors PTO and the machines gearbox stub shaft are approximately in line. ASSEMBLY • The four levers of machine controls must be operated from the tractor seat. During this operation ensure no one is standing on or among the linkage arms or bars. Set tractor hydraulics to position control. Never allow anyone below the frame unless it is securely blocked up.
ASSEMBLY 1900 07/10 © 2010 Alamo Group Inc. Assembly Section 3-7 ASSEMBLY Check the welded in pins between the stabilizers jaws are in contact with the mounting rail. If not the machine must be lowered to the ground and the next higher hole on the stabilizer valve selected, the machine raised and contact checked. Repeat again in the third hole if necessary. On subsequent fitting to the same tractor the hole selected is always used.
ASSEMBLY ASSEMBLY • Adjust using the mounting hole that allows the P.T.O. and gearbox shaft to align as near as possible. • Fit positioning stops - these remain in position until tractor is changed. • Lower tractor linkage control so that the machine weight is taken by the yoke. 1900 07/10 © 2010 Alamo Group Inc.
ASSEMBLY Raise the stand legs into the work position and secure with lock pins. • Tighten check chains and/or stabilizer bars. • Fit machine controls into the cab. (Optional Cables available) • Measure P.T.O. and cut to dimension shown. ASSEMBLY • Note: for subsequent use on different tractors measure again - there must be a minimum shaft overlap of 150mm. 1900 07/10 © 2010 Alamo Group Inc.
ASSEMBLY Fit PTO shaft in position. • Attach torque chains to a convenient location to prevent rotation of the shaft guarding. • Ensure the Lift Ram tap and Slew Ram taps are open. • Operate the lift up controls and raise the dipper arm end just enough to clear the ground. • Pivot out the dipper arm until the tension link can be connected. ASSEMBLY • Do Not attempt to raise or lower the boom or mower head unless the Implement is securely attached to the Tractor.
ASSEMBLY Flailhead Attachment Operate machine controls to maneuver boom arm into flailhead attachment. The bottom of the hose connection bracket must be parallel with the ground. Refer to torque chart for correct bolt torque settings. ASSEMBLY With the arms at half reach and the flailhead clear of the ground carry out final adjustment of the lift arm leveling box to bring the main frame horizontal.
ASSEMBLY ASSEMBLY OIL REQUIREMENTS Tank Rear mounted hydraulic pumps are attached directly to the tractor PTO and will be operating when the tractor engine is running. Never start a tractor with a rear mounted pump attached without first filling the hydraulic tank with the correct hydraulic oil. Rhino specifies hydraulic oil based on ambient operating temperature ranges as prescribed in iso standards. The most common oil used in Rhino mowers is the AW ISO VG 100 Oil.
ASSEMBLY REMOVAL FROM TRACTOR Read carefully before commencing to remove the machine from the tractor. The order of the following steps must be followed exactly. Disconnecting the top link must be the last operation prior to driving the tractor away from the machine. Do not operate valve lever or machine controls through the rear cab window while standing on or among linkage components. Always seek assistance. Select a firm level site for parking the machine.
ASSEMBLY STORAGE ASSEMBLY If machine is to be left standing for an extended period of time, lightly coat the exposed portions of the ram rods with grease. Subsequently this grease should be wiped off before the rams are next moved. If the machine has to be stored outside tie a piece of tarpaulin or canvas over the control assembly, do not use a plastic fertilizer bag which could lead to rapid corrosion. SUBSEQUENT ATTACHMENT TO IDENTICAL TRACTOR Refer to and follow steps on ‘initial attachment to tractor.

The mower head will come to a complete stop within a suitable amount of time. Do not engage or disengage the cutterheads at a high RPM unless there is an emergency situation.
OPERATION • • • OPERATION • • • Thoroughly clean all debris from boom and head to prevent damage from rotting grass and standing water. Lubricate all grease points and fill oil levels according to the maintenance lubrication schedule. Tighten all bolts to the proper torque. Ensure all pins and other hardware are in place. Check the boom arm and head for worn and damaged parts. Perform repairs and make replacements so that the mower will be ready for use at the start of the next season.
OPERATION TRANSPORT POSITION • • • • Select ROTOR OFF and wait until rotor has stopped turning Ensure that the “LIFT” and “ANGLE FLOAT” are switched “OFF” Select “SLEW” mode on the control assembly. Operate “SLEW IN” Operate “LIFT” and “REACH” to position the machine. • Operate “REACH IN” until dipper arm contacts the transport cradle. Select “LIFT UP” and raise the arms until the tension link is 300mm from the tractor cab. Operate “ANGLE” and position the flail head in as compact position as possible.
OPERATION 19. TRANSPORT POSITION-Head Attached OPERATION The machine is transported in line to the rear of the tractor with a minimum of 300mm clearance between the tension link and the rear cross member of the tractor cab. 20. TRANSPORT POSITION-Head Removal With the flail head removed the arms are fully folded but the lift ram remains retracted.
OPERATION 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. Use extreme caution and avoid hard applications of the tractor brakes when towing heavy loads at road speeds. Never tow the implement at speeds greater than 20 MPH (25 kph).
OPERATION OPERATION The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day and night visibility. Make sure the SMV sign is clean and visible from the rear of the unit before transporting the tractor and implement on a public roadway. Replace the SMV emblem if faded, damaged, or no longer reflective.
OPERATION Reduce speed before turning or applying the brakes. Ensure that both brake pedals are locked together when operating on public roads. OPS-U- 0023 20.2 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 1900 07/10 © 2010 Alamo Group Inc.
OPERATION OPERATION Use adequately sized and rated trailers and equipment to transport the tractor and implement. Consult an authorized dealer to determine the proper equipment required. Using adequately sized chains, heavy duty straps, cables and/or binders, securely tie down both the front and rear of the tractor utilizing the proper tie down locations as specified by the tractor manufacturer. OPS-U- 0025 Arrange the chains so that when tightened, the chains are pulling downward and against themselves.
OPERATION 21. TROUBLESHOOTING GUIDE POSSIBLE CAUSE POSSIBLE REMEDY Hydraulic Cylinder Not Working Hydraulic level low. Check hydraulic fluid level. (See sight gauge on tank) Attempt to use another cylinder or pressure gauge. Check line for stoppage. Pump not functioning properly. Cylinder not functioning properly.

MAINTENANCE MAINTENANCE LUBRICATION General Grease all locations shown daily. PTO SHAFT INSPECTION 1. Regularly check the PTO guards for damage and ensure the anti rotation chains are in place and that their anchor points are in good condition. Do not operate the machine with any damaged guards - replace suspect items immediately. PTO SHAFT LUBRICATION 2. Lubricate all the points indicated in the diagram below at the intervals stated using a general purpose lithium based grease.
MAINTENANCE HYDRAULIC SYSTEM Oil Supply Filtration Maintenance A 125-micron suction strainer and a low-pressure 10-micron full flow return line filter protect the machine. Suction strainer The strainer is permanently fixed within the reservoir. Should symptoms of pump cavitation or spongy intermittent operation occur the tank must be drained and flushed out with a suitable cleaning agent e.g. clean diesel oil.
MAINTENANCE MAINTENANCE Hose Replacement 1. Replace one hose at a time to avoid the risk of wrong connections. 2. When the hose is screwed to an additional fitting or union, use a second spanner on the union to avoid breaking both seals. 3. Do not use jointing compound on the threads. 4. Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening hose end connections. Before changing hoses, study the installation.
MAINTENANCE FLAILHEAD CABLES The cables operate on a push/pull system with the spool centering springs always returning the spool to the neutral position when the handle is released. Care should be taken during installation and operation to ensure that the cables are not trapped or kinked. Any abrasion or damage to the outer casing should be sealed with plastic insulation tape to avoid moisture penetrating. No routine adjustment of the cables are necessary as they do not stretch.
MAINTENANCE MAINTENANCE PTO GEARBOX Refill the gearbox after the first initial 50 hours and thereafter yearly or 500 hour intervals. or whichever comes first. Drainage of the gearbox for an oil change is via the drain plug located on the base of the gearbox. To refill or for ‘topping up’ remove both plugs indicated below and fill gearbox via the filler plug to a point where the oil starts to run from the level plug orifice – replace plugs and tighten securely.
MAINTENANCE PROPER TORQUE VALUES FOR FASTENERS The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to this chart to determine the grade of bolts and the proper torque except when specific torque values are assigned in manual text. RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL* 1900 07/10 © 2010 Alamo Group Inc.
