OPERATION OPERATION RHINO CY60/72 HEAVY-DUTY ROTARY MOWER OPERATION INSTRUCTIONS Rhino Cyclone 60 and 72 (CY60/72) Heavy-Duty Rotary Mowers are manufactured with quality material by skilled workers. These rugged mowers are engineered for cutting vegetation up to 3” diameter in commercial, industrial, and agriculture applications such as mowing rights-of-way, roadsides, and pastures.
OPERATION 1. Standard Equipment and Specifications CY72 40 HP Cutting Capacity (Max.) 4” Cutting Height 1-9/16” Safety Deflector Rubber Belting Cutting Width 72” Overall Width 79-1/4” Overall Length 118” Base Unit Weight (Approx.) 1338 lbs.
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 horsepower required to operate the mower depends on several operating factors including the vegetation to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most mowing conditions, the CY72 mower requires a tractor with a minimum of 40 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 75 HP may cause mower damage by overpowering the unit in heavy cutting conditions. OPERATION 3.
OPERATION 3.5 Power Take Off (PTO) Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft or a 1-3/4” 20 spline shaft.
OPERATION 4.1 Boarding the Tractor Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt around you. OPERATION Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be seriously injured or killed from falling off and being ran over.
OPERATION 5. 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) 1. OPERATION 2. 3. 4. 5. 6. 7. 8. Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed. Shorten or remove the tractor drawbar to avoid interference when raising and lowering the mower. Board the tractor and start the engine.
OPERATION Never work under the Implement, the framework, or any lifted component unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death. (SG-14) 7.1 Setting Mower Height 3. 4. 5. 6. 7. 8. Park the tractor and mower on level ground. 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.
OPERATION 7.2 Setting Deck Pitch OPERATION To facilitate safe and efficient 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. In addition, a more even distribution of the clippings from the rear of the mower will be achieved with this deck pitch.
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 driveline can cause personal injury.
OPERATION CY72 Mowers The CY72 driveline is a bar and welded sleeve assembly and its length cannot be modified as described above. Contact your authorized dealer or Rhino Customer Service for recommendations to fit the mower to the tractor if there is a potential problem bottoming out the driveline. Engagement Check Procedure OPERATION • • • • • With the driveline attached, raise and lower the mower within its operating range.
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 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. OPERATION • • • • • • Ensure the manual canister is secured to the equipment with the operator’s manual inside. Ensure all safety signs are in place and legible. Replace missing, damaged, and illegible decals.
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. 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 • 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 Replace bent or broken blades with new blades.
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)” CY72 01/08 © 2008 Alamo Group Inc.

OPERATION 10. 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. To ensure safety while driving the tractor with an attached implement, review the following.
OPERATION 10.1 Starting the Tractor OPERATION 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. OPS-U-0033 10.2 Brake and Differential Lock Setting Make sure the tractor brakes are in good operating condition.
OPERATION 10.3 Raising the Mower be raised to avoid driveline damage. OPS-R-0042 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 10.5 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).
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. resulting in possible damage and premature wear. OPS-R-0022 11.
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. Inspect the cutting area for such objects before mowing. Remove any like object from the site. Never allow the cutting blades to contact such items. (SGM-6) OPERATION 11.
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 When you get to the end of a pass, slightly raise the mower (2-4”) before turning. Never raise the mower entirely while the blades are turning. If the mower must be raised higher than 12” from ground level, disengage the tractor PTO and wait for all mower rotation to come to a complete stop before proceeding to raise the mower. When turning, the angle between the tractor and mower should not be so great that a clattering of the U-joints occurs.
OPERATION Then lower the mower to the desired height and mow the vegetation a second time. If possible, select a mowing pattern that is at a 90 degree angle to the first pass to reduce streaking for a more uniform cut. OPS-R-0044 to avoid hitting these items. OPS-R-0028_A CY72 01/08 © 2008 Alamo Group Inc. Operation Section 4-33 OPERATION Stay alert and watch for trees, low hanging limbs, power lines, and other overhead obstacles and solid ground objects while you are operating.
OPERATION 11.6 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 OPERATION proceeding to drive or shut down the tractor.
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) 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.
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 14. TRANSPORTING THE TRACTOR AND IMPLEMENT Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind when you finish working in an area. Therefore, the operator must employ good judgement and safe operation practices when transporting the tractor and implement between locations.
OPERATION 14.2 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 When operating on public roads, have consideration for other road users. Pull to the side of the road occasionally to allow all following traffic to pass. Do not exceed the legal speed limit set in your country for agricultural tractors. Always stay alert when transporting the tractor and implement on public roads. Use caution and reduce speed if other vehicles or pedestrians are in the area. OPSU- 0022 Reduce speed before turning or applying the brakes.
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.

MAINTENANCE SECTION Maintenance Section 5-1 © 2008 Alamo Group Inc.
MAINTENANCE Before operating your Rotary Cutter, make sure it is properly lubricated and thoroughly inspected. Only a minimum of time and effort is required to regularly lubricate and maintain this machine to provide long life and trouble free operation. MAINTENANCE Always disengage the PTO before raising the Rotary Cutter for transporting or making adjustments. Lubrication Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
MAINTENANCE Gearbox Lubrication (Figure Mnt-0001 and Mnt-0011) Check the oil level after operating long enough for warmed oil to flow through the Bearings into the lower Gearbox cavity. Refill to the test plug level. Check the oil again before operation, after every 40 hours of mowing, and at the beginning and end of each mowing season. NOTE: Overfilling the Gearbox will cause pressure to build up and cause Oil Seals to leak.
MAINTENANCE MAINTENANCE Driveline Lubrication Grease Fittings are located on the Cross Assembly of each U-Joint (Figure Mnt-0002) and on the Round Housing (Figure Mnt-0003). Grease the UJoint after each 8 hours of use. Do not force grease through the Needle Cup Assemblies. Grease the Round Housing after every 8 hours of use, except in sandy soil conditions. Some PTO-to-Hitch connections may necessitate cutting a hole in the shields to be able to align the Grease Fitting holes for lubrication.
MAINTENANCE Driveline Shields/Slip Clutch Service Make certain that the Driveline Integral Shields are free to telescope and rotate around the Driveline without binding. Torque Limiter (CY72) Avoid overheating of the Torque Limiter by too long or too frequent slipping, as this can damage the friction plates and limiter parts. When checking Torque Limiter for overheating, DO NOT touch with hand. Torque Limiter could be extremely hot and cause severe burn.
MAINTENANCE Seasonal Torque Limiter Maintenance (CY72) MAINTENANCE It is important that the Torque Limiter slips when an obstacle or load heavier than the setting is encountered. Before using the cutter each season, use the following procedure to make sure the torque limiter will slip and give the overload protection required. 1. Loosen Bolts (#8) until gap between adjusting nut (#7) and guide ring is approximately 1/16". 2.
MAINTENANCE Blade Carrier Installation Clean the splines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and install special washer nut. Tighten nut holding blade carrier to minimum 400 ft. pounds, strike the carrier near the hub several times with a heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads. Retighten the nut to 400 ft. pounds. Install cotter pin and spread. Avoid personal injury.
MAINTENANCE MAINTENANCE Avoid personal injury. Always block the cutter up to prevent it from falling when the blades and/or carrier are being serviced. 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 POSSIBLE SERIOUS INJURY FROM THROWN BLADES.
