Page 50 ALAMO INDUSTRIAL RX60-3, RX72-3, & RX84-3 ROTARY MOWER OPERATION INSTRUCTIONS Alamo Industrial rotary mowers are manufactured with quality material by skilled workers. These mowers are designed to cut grass, weeds, small brush and other vegetative material up to 3” diameter in areas such as pastures, industrial areas, and roadsides.
Page 51 OPERATION 1. OPERATOR REQUIREMENTS 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.
Page 52 OPERATION 2. 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.
Page 53 OPERATION 2.3 Tractor Horsepower The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the RX60-3 mower requires a tractor with at least 35 HP, the RX72-3 mower requires a tractor with at least 45 HP and the RX84-3 requires 60 HP.
Page 54 OPERATION Drawbar-Pull Type Mower For equipment operating at 540 RPM, the tractor draw- bar must be positioned at a 14” distance from the hitch point to the PTO shaft end for proper operation and min- imal wear to the driveline. 1000 RPM Models require 16 inch drawbar length.
Page 55 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 implement failure. Adapter use will also change the working length of the driveline exposing unshielded driveline areas.
Page 56 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) 3.2 Dismounting the Tractor Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake, idle the engine down, disengage the PTO, and lower the implement to the ground.
Page 57 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) 5. 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.
Page 58 OPERATION 4. Turn off the tractor engine and dismount. 5. One lift arm at a time, align arm end hole between the set of A-frame lift lugs. Insert hitch pin through the lug and arm holes and insert retaining pin into hitch pin. 6.
Page 59 OPERATION 5.3 Connecting Mower - Lift Type (Quick Hitch) 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.
Page 60 OPERATION IMPORTANT: Scan this QR Code with your smart phone to link to the PAMI Safe Implement Hitching Manual for more information on correctly connecting agricultural tractors to implements. Or type in your internet browser the following web address: www.algqr.com/hme Ops-0008-MISC 6.
Page 61 OPERATION 5. Level the mower side to side by manipulating one lower lift arm length. On most tractors, at least one of the lift arms is designed to allow for manipulation of its length. Shortening or extending will allow for deck leveling from side to side.
Page 62 OPERATION 6.2 Connecting the Mower-Pull Type 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.
Page 63 OPERATION 6.3 Setting Mowing Height-Pull Type 1. Park the tractor and mower on level ground. 2. Using the tailwheel ratchet jack or hydraulic cylinder, position the mower so the skid shoes are 1” less off the ground than the desired final cut height.
Page 64 OPERATION 6.4 Setting Deck Pitch Lower Horse Power - Better Fuel Efficiency To increase fuel efficiency and lower horsepower requirements for mower operation, the mower should be operated with the deck approximately 3/4" LOWER IN THE FRONT THAN THE REAR. Operating the mower at this pitch will allow the mower to cut the grass only once and requires less work from the tractor.
Page 65 OPERATION When attaching the Implement input driveline to the Tractor PTO, it is important that the connecting yoke spring activated locking collar slides freely and the locking balls are seated securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth several times to ensure it is securely attached.
Page 66 OPERATION Shorten the driveline profiles as follows: • Remove the driveline from the tractor. • Raise and lower the mower to find the position with the shortest distance between the tractor PTO shaft and cutter gearbox. Shut down the tractor and securely block the mower in this position.
Page 67 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.
Page 68 OPERATION The operator’s manual and safety signs affixed on the unit contain important instructions on the safe and proper use of the equipment. Maintain these important safety features on the implement in good condition to ensure the information is available to the operator at all times.
Page 69 OPERATION All Safety Shields, Guards and Safety devices including (but not limited to) - the Deflectors, Chain Guards, 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.

Page 76 OPERATION 9. DRIVING THE TRACTOR AND IMPLEMENT Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the implement and the tractor operating controls are set for safe transport.
Page 77 OPERATION 9.1 Starting the Tractor The procedure to start the tractor is model specific. Refer to the tractor operator’s manual for starting procedures for your particular tractor. Consult an authorized dealer if the starting procedure is unclear. Ensure the 3-point control lever is in the lowered position and the PTO is disengaged before starting the tractor.
Page 78 OPERATION 9.3 Raising the Mower Using the tractor 3-point hitch control lever, raise the mower off the ground about 6”, or just high enough to clear any ground obstacles. When raising the mower, make sure all connection points are securely attached and at least 1” clearance is maintained between the driveline and the deck.
Page 79 OPERATION 9.5 Crossing Ditches and Steep Inclines When crossing ditches with steep banks or going up sharp inclines, it is possible that the main driveline inner profile will penetrate into the outer housing to its maximum depth until the assembly becomes solid (driveline is at its extreme shortest length).
Page 80 OPERATION 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. If the gradient is so steep that such an approach increases the possibility of a tractor roll-over, select an alternate crossing path.
Page 81 OPERATION Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death.
Page 82 OPERATION Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 ft (100 m) or more) and causing serious injury or death. Follow safety messages carefully. STOP MOWING IF PASSERSBY ARE WITHIN 300 Feet (100 m) UNLESS: -Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;...
Page 83 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(3-8 kph). Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut.
Page 84 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 300 feet (90 m) in front and to the sides of the tractor and mower.
Page 85 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.
Page 86 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.
Page 87 OPERATION 10.6 Shutting Down the Implement To shut down attached mower head, first bring the tractor to a complete stop. Decrease engine RPM to idle then disengage cutterhead. The mower head will come to a complete stop within a suitable amount of time.
Page 88 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) To disconnect the mower, first extend the tractor 3- point hitch top link to remove tension on the top link hitch pin.
Page 89 OPERATION 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. The following are suggested storage procedures: • Thoroughly clean all debris off the mower to prevent damage from rotting grass and standing water.
Page 90 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. Once all mower parts are completely stopped, raise the mower to transport height. NOTE: When raising the mower, maintain 1”...
Page 91 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.
Page 92 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 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.
