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) Operator Safety Instructions and Practices The rotating parts of this machine continue to rotate even after the PTO has been turned off.
SAFETY Always read carefully and comply fully with the manufacturer’s 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. (SG-36) Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection when servicing hot components.
SAFETY SAFETY 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. Operating the Mower with excessive vibration can result in component failure and broken objects to be thrown outward at very high velocities.
SAFETY 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. (SG-23) Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause Implement driveline or blade failures resulting in serious injury or death.
SAFETY SAFETY 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(90 m) in front and to the sides of the tractor and mower. Make sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign objects. If you are unable to clearly see these type of items discontinue mowing.
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-08) Do not mow with two machines in the same area except with Cab tractors with the windows closed.
SAFETY Rotary 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 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) Never operate the Tractor and Mower if the Implement input driveline is directly connected to the Tractor transmission.

OPERATION 2. OPERATOR REQUIREMENTS OPERATION Safe operation of the unit is the responsibility of a qualified operator. 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 signs are affixed to the implement and tractor.
OPERATION 3. TRACTOR REQUIREMENTS The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take Off (PTO) at the mower’s rated speed while traveling 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 be a potential danger to the operator and passersby.
OPERATION The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the RX60 mower requires a tractor with at least 35 HP, the RX72 mower requires a tractor with at least 45 HP and the RX84 mower requres a tractor with at least 65 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
OPERATION 3.5 Drawbar-Pull Type Mower For equipment operating at 540 RPM, the tractor drawbar must be positioned at a 14” distance from the hitch point to the PTO shaft end for proper operation and minimal wear to the driveline. OPS-R- 0061 3.6 Power Take Off (PTO) This mower is designed to operate at a PTO speed of 540. Most tractors operate at either 540, or a combination of 540 and 1000 RPM PTO speeds.
OPERATION DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor PTO. Use of an adapter can double the operating speed of the Implement resulting in excessive vibration, thrown objects, and blade and implement failure. Adapter use will also change the working length of the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure can result from using a PTO adapter.
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) 4.2 Dismounting the Tractor Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud, ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support and never rush or jump off the tractor. OPS-U- 0009 5.
OPERATION OPERATION 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) 6. CONNECTING THE MOWER TO THE TRACTOR Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points between the tractor hitch arms and mower pins.
OPERATION 8. Adjust any lower link check chains, guide blocks, or sway blocks to prevent the mower from swaying side to side and possible contact with tractor rear tires. Note: Offset Adaptor Hitches are available to position the mower to the left or right. Mowers with Offset Adaptor hitches connect to the 3-Point hitch the same way as the mower A-frame. See Offset Adaptor Hitch in the Assembly Section for details to equip the mower with this feature. 6.
OPERATION 6.3 Connecting Mower - Lift Type (Quick Hitch) OPERATION Crushing Hazard between Quick-Hitch and Implement. Do not allow anyone to stand between the Quick-Hitch and implement during hook-up operations. Never operate the hydraulic 3-point lift controls while someone is directly behind the tractor. 1. Make certain the implement’s upper and lower hitch pins are secured. 2. Lower the tractor’s 3-point lift until the three Quick-Hitch hooks are lower than the implements hitch pins.
OPERATION 7.1 Setting Mower Height- Lift Type - (Standard or Quick Hitch) RX60/72/84 03/09 © 2009 Alamo Group Inc. Operation Section 4-13 OPERATION 1. Park the tractor and mower on level ground. 2. Using the 3-point hitch control lever, position the front of the mower with the side skids 1” less off the ground than desired cut height. For example, for a 3” cut, position the skids 2” from the ground.
OPERATION OPERATION 9. Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2½" before the tail wheel leaves the ground. This will allow the mower to follow the contour of uneven terrain. Note: Install optional check chains when there is a problem with the hydraulic 3-Point lift maintaining a set height or when a constant pre-adjusted cut height is required. See Check Chains in the Assembly Section for this accessory.
OPERATION 7.2 Connecting the Mower-Pull Type RX60/72/84 03/09 © 2009 Alamo Group Inc. Operation Section 4-15 OPERATION 1. Make sure the tractor is equipped with the correct PTO shaft and the drawbar is extended 14” from the end of the PTO shaft to the hitch point. 2. Block the mower wheels in place and use the attached parking jack to raise or lower the tongue clevis to the height of the tractor drawbar. The parking jack can be rotated 15 degrees in each direction to obtain a near vertical position.
OPERATION 7.3 Safety Tow Chain OPERATION If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the gross weight of the mower must be connected between the tractor and mower. This will help control the implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached to a secure location on the tractor and not to an intermediate support.
OPERATION 7.5 Setting Deck Pitch To facilitate safe and efficient operation, the mower should be operated with the deck approximately 3/4” LOWER IN THE FRONT THAN THE REAR. Setting Deck Pitch-Lift and Semi-Mount Type 8. DRIVELINE ATTACHMENT The driveline yoke and tractor PTO shaft must be dirt free and greased for attachment. To connect the mower driveline to the tractor PTO output shaft, pull the driveline yoke collar back and align the grooves and splines of the yoke with those of the PTO shaft.
OPERATION 8.1 Driveline Length Check 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.
OPERATION Shorten the driveline profiles as follows: • • • • • • Engagement Check Procedure • • • • • With the driveline attached, raise and lower the mower within its operating range. Position the mower to the point where the telescoping driveline is at its maximum extension. Completely shut down the tractor and secure in position. Mark the inner driveline shield 1/8” from the end of the outer shield. Disconnect the driveline from the tractor and separate the two driveline halves.
OPERATION 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) RX60/72/84 03/09 © 2009 Alamo Group Inc.

Ensure the driveline integral shield is in good condition and rotates freely. Ensure the driveline slip clutch (if equipped) is properly adjusted. OPS-R-0039 Inspect the gearbox oil level. A low oil level is a warning sign that the gearbox may be cracked or its seal is damaged and needs replacement. Ensure the gearbox vent is in place and free from clogs.
OPERATION • OPERATION • Inspect blades and blade bolts for looseness and excessive wear. Make sure the mower is securely blocked up before crawling beneath. Replace damaged, worn and missing blades as complete sets to maintain rotary balance during operation. Ensure carrier hub nut is tightened with the cotter pin inserted and spread. OPS-R-0041 9.3 Cutting Component Inspection Inspect blade pan and blade assembly for the following: OPS-U-0031 RX60/72/84 03/09 © 2009 Alamo Group Inc.
OPERATION Inspect the Blades daily for abnormal wear. REPLACE BOTH BLADES on that carrier IMMEDIATELY if either blade has: • • • • • Become bent or deformed from it’s original shape or Any cracks are visible, or Deep gouges in the blade’s surface are persent, or Gouges or chipped areas in the cutting edge are larger than 1/2”(12.7mm), or The material on the leading edge has been worn away by more than 1/2(12.7mm)” broken part with tremendous force which may cause serious bodily injury or death.
OPERATION 9.4 Blade Bolt Inspection OPERATION Inspect Blade Bolt Head daily for wear as followed: Inspect the Blade Bolt Heads daily for abnormal wear. REPLACE BOTH BLADE BOLTS on the Blades IMMEDIATELY if either blade bolts has: • Visible cracks or • If the recessed area on blade bolt is worn off or • If Blade Bolt has gouges or chipped areas.
OPERATION 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. Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment.
OPERATION OPERATION 10.2 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 10.4 Driving the Tractor and Mower Start off driving at a slow speed and gradually increase your speed while maintaining complete 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 OPERATION When confronted with an incline or ditch, do not approach from an angle which is perpendicular or straight on as damage to or over-collapse of the driveline may occur. OPS-R-0021_A Inclines and ditches should be approached along a line which is at an angle as shown. This type of path will reduce the possibility of over-collapse of the driveline and resulting damage.
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. Repair all damage and make certain rotor or blade carrier is balanced before resuming mowing.
OPERATION 11.1 Foreign Debris Hazards OPERATION 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. If you hit a solid object or foreign debris, stop the mower and tractor at once. Immediately idle the engine speed and disengage the PTO.
OPERATION Rotary 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.
OPERATION 11.4 PTO RPM and Ground Speed OPERATION 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(3-8 kph). 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 Do not mow with two machines in the same area except with Cab tractors with the windows closed. (SGM-11) 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.
OPERATION OPERATION 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) Large, dense, or wet vegetation may need to be mowed in two or more passes to achieve a uniform cut. In such conditions, raise the cutting height to 12” or more on the first pass.
OPERATION Do not mow, or drive the tractor into material that is burning, or areas that recently burnt and may contain hot spots. Burning material, sparks, and coals could be thrown from the mower to areas of vegetation that might ignite. Tire damage can occur when driving over hot material. Oil and grease on the tractor and mower could ignite resulting in equipment destruction. Carry a fire extinguisher on the tractor at all times to extinguish possible fires encountered. 11.
OPERATION 12. DISCONNECTING THE MOWER FROM THE TRACTOR OPERATION Before disconnecting the mower, the PTO must be disengaged and blade rotation at a complete stop. Move the mower to a level storage location and lower it 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 caused by the tractor hitch arms and mower pins.
OPERATION To disconnect the mower, first extend the tractor 3point hitch top link to remove tension on the top link hitch pin. When the pin is loose and easy to rotate, remove the pin from the mower. Next remove both lower hitch pins. RX60/72/84 03/09 © 2009 Alamo Group Inc. Operation Section 4-41 OPERATION After disconnecting the 3 lift points, remove the mower driveline from the tractor PTO shaft. Lay the driveline down carefully on support flat to avoid damaging the driveline or its shield.
OPERATION 13. 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. The following are suggested storage procedures: • OPERATION • • • • • • Thoroughly clean all debris off the mower to prevent damage from rotting grass and standing water. Lubricate all mower grease points and fill gearbox oil levels as detailed in the maintenance section.
OPERATION If the tractor’s hydraulic pump is not independent of the tractor PTO, or if the tractor PTO has to be run to have hydraulic power, disconnect the mower driveline from the tractor PTO output shaft. Secure the driveline to the mower deck to prevent driveline damage or loss during transport. OPS-R-0034 14.1 Transporting on Public Roadways Extreme caution should be used when transporting the tractor and implement on public roadways.
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 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.
OPERATION OPERATION Arrange the chains so that when tightened, the chains are pulling downward and against themselves. Carefully tighten the securing chains or other fasteners using boomers or binders to apply maximum tension. Use extreme care when attaching and removing the securing devices as the extreme tension involved when released has the potential to inflict serious injury.
OPERATION 15. TROUBLESHOOTING GUIDE Problem Possible Cause Remedy Excessive Vibration Check Gearbox Bolts Check for loose nuts on blade holder and blades. Check for bent output shaft. If shaft is bent, oil will normally leak from bottom seal. Check to see if blades are free swinging. Check for even wear on each blade tip. Were both blades changed at the same time? Blade Broken. Blade Carrier Bent. Blade hub not properly seated on shaft. New blade or bolts matched with worn blade or bolts.
OPERATION Bolts not tightened. Bolt hole elongated or oversized. Locknut worn out. Tighten Bolts to 300 ft./lbs. Replace Blade Carrier. Replace Locknut. Gearbox Noisy Low Lubricant. Rough gears. Worn Bearing. Check lubricant level. Run in or change Gears. Replace Bearing. Gearbox Leaking Damaged Oil Seal. Bent Shaft. Oil Seal Race rough. Oil Seal installed wrong.
