INTRODUCTION INTRODUCTION We are pleased to have you as a Rhino customer. Your Rotary Cutter has been carefully designed with care and built with quality materials by skilled workers to give maximum service with minimum down time. This manual is provided to give you the necessary operating and maintenance instructions for keeping your rotary cutter in top operating condition. Careful use and timely service saves extensive repairs and costly downtime losses. Please read this manual thoroughly.
INTRODUCTION INTRODUCTION The Rhino TW120 Rotary Mower is designed for medium duty applications such as weed, grass, corn stalks, and light brush to 2" diameter. These mowers are single spindle with two free-swinging blades. Free swinging blades reduce the shock of impact when a stationary object is hit. Additional protection is provided by a slip clutch on the gearbox input shaft. A round blade holder allows the mower to “ride over” stumps and similar immovable objects.
INTRODUCTION INTRODUCTION KEY OPERATION POINTS • Cutting performance and distribution are best when cutter is level from side to side and front to rear. • In extra heavy material, rear chains will allow better discharge and better distribution than solid rear bands. • Never operate the Mower below full PTO speed of 540 or 1000 rpm. • Corn should be cut at 5 to 6 mph. If full PTO rpm cannot be maintained, use one lower gear.

OPERATION SECTION Operation Section 4-1 © 2011 Alamo Group Inc.
OPERATION RHINO TW120 ROTARY MOWER OPERATION INSTRUCTIONS OPERATION Rhino 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 2” diameter in areas such as pastures, industrial areas, and roadsides. The mower is equipped with protective deflectors and/or chain guards to prevent objects being thrown from the mower by the blades, however, no shielding is 100% effective.
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.
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.
OPERATION 2.2 Tractor Safety Devices If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning signals are obscured. Maintain all manufacturer equipped safety shields and guards.
OPERATION 2.5 Drawbar-Pull Type Mower OPERATION For pull type mowers (540 and 1000 RPM) equipped with an equal-angle driveline, 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 and tractor. If attaching the mower tongue clevis to a 3-point hitch drawbar supported by the lower lift arms, the attaching point must be extended past the main bar to allow for turning without binding the clevis and bar.
OPERATION 2.7 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. 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.
OPERATION 3. GETTING ON AND OFF THE TRACTOR Before getting onto the tractor, the operator must read and completely understand the implement and tractor operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete explanation. OPS-U- 0007 OPERATION Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completelystopped. (SG-12) 3.
OPERATION BEFORE leaving the tractor seat lower the implement, set the parking brake and/or set the tractor transmission in parking gear, disengage the PTO, stop the engine, remove the key, and wait for all moving parts to stop. Place the tractor shift lever into a low range or parking gear to prevent the tractor from rolling. Never dismount a Tractor that is moving or while the engine is running. Operate the Tractor controls from the tractor seat only.
OPERATION 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. Keep hands and feet from under the mower deck and clear of pinch points between the tractor hitch arms and mower pins.
OPERATION 5.2 3-Point Quick Hitch Our 3-Point Quick Hitch is designed to connect to a Quick-Attach Coupler making mounting and dismounting your mower easier. The 3-Point Quick Hitch is also designed to connect the cutter to a tractor’s three-point linkage without the use of a Quick-Attach Coupler. Crushing Hazard between Quick-Hitch and Implement. Do not allow anyone to stand between the Quick-Hitch and implement during hook-up operations.
OPERATION 5.4 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. If using a hydraulic cylinder, connect hydraulic hose ends into tractor hydraulic ports. 8. If the mower has been attached to a 3-point hitch drawbar, adjust any tractor equipped lower link check chains, guide blocks, or sway blocks to prevent the hitch and mower from swaying side to side. Note: Never raise the 3-point lift with the mower attached as catastrophic driveline damage will occur. 6.
OPERATION 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. 6. Securely block up the mower at this height. 7. Remove the bolts securing the tailwheel beam support brackets and allow the tailwheel(s) to rest at ground level.
OPERATION 6.3 Setting Deck Pitch Lower Horse Power - Better Fuel Efficiency Increase Mulching To increase mulching of the grass or crop material during mower operation, the mower should be operated with the deck approximately 3/4" HIGHER IN THE FRONT THAN THE REAR. Operating the mower at this pitch will allow the mower to cut the grass twice and can result in a more even cut and improved distribution of the cut material.
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. A driveline not attached correctly to the Tractor PTO shaft could come loose and result in personal injury and damage to the Implement. (S3PT-17) OPERATION 7.
OPERATION Shorten the driveline profiles as follows: • • • • • • Engagement Check Procedure • With the driveline attached, 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. • Measure the distance from the mark to the end of the inner profile.
OPERATION 7.2 Constant Velocity (CV) Driveline Mowers are equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor and mower must be determined to ensure the joint angle does not over-extend which can cause CV joint damage. Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at angles up to 80°. Angles greater than 80° will result in mechanical damage to the CV joint and mower driveline.
OPERATION 8. PRE-OPERATION INSPECTION AND SERVICE Before each use, a pre-operation inspection and service of the implement and tractor must be performed. This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing parts as soon as noticed.
OPERATION OPERATION 8.1 Tractor Pre-Operation Inspection/Service 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 8.2 Mower Pre-Operation Inspection/Service Before each mower use, a complete inspection and service is required to ensure the mower is in a good and safe working condition. Damaged and/or broken parts should be repaired and/or replaced immediately. To ensure the mower is ready for operation, conduct the following. OPS-R-0007 • • • • • • • • Ensure the manual canister is secured to the equipment with the operator’s manual inside. Ensure all safety signs are in place and legible.
OPERATION 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.
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. Ensure the blade carriers are properly timed to avoid blade contact during operation. See instructions to properly time blades in the Maintenance Section.
OPERATION 8.3 Cutting Component Inspection OPERATION Inspect blade pan and blade assembly for the following: OPS-U-0031 TW120 01/11 © 2011 Alamo Group Inc.
OPERATION Operating the mower with loose blade hardware will damage the blade holder or blades and can result in blade breakage or blade fastener failure. Broken blades or bolts can be thrown out from under the mower for distances up to 300 feet. When the blades are replaced, the fastening hardware must be replaced. Check and retighten the blade hardware after the first eight hours of operation. In severe cutting conditions, recheck the blade carrier and blade bolt torque every 50 hours.
OPERATION 8.4 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 Rotary Mower PRE-OPERATION Inspection Mower ID#________________ Make ____________________ Date: Shift ________________ ____________________ OPERATION Before conducting the inspection, make sure the tractor engine is off, all rotation has stopped and the tractor is in park with the parking brake engaged. Make sure the mower is resting on the ground or securely blocked up and all hydraulic pressure has been relieved. Condition at Start of Shift Item Specific Comments if not O.K.
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. To ensure safety while driving the tractor with an attached implement, review the following.
OPERATION 9.1 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 9.2 Brake and Differential Lock Setting Make sure the tractor brakes are in good operating condition.
OPERATION 9.3 Raising the Mower 9.4 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 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).
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. 10. OPERATING THE TRACTOR AND IMPLEMENT THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE.
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-06) OPERATION 10.
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 10.4 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 10.6 Right of Way (Highway) Mowing • USE DOUBLE CHAIN GUARDS for highway, right-of-way, parks, greenbelt mowing, or all other mowing where human dwellings, vehicles, or livestock could be within 300 feet of the mower. • No shielding is 100% effective in preventing thrown objects. To Reduce Possibility of Injury: 1. MAINTAIN MOWER SHIELDING in good operational condition, 2.
OPERATION 10.7 Shutting Down the Implement OPERATION 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. Do not engage or disengage the cutterheads at a high RPM unless there is an emergency situation.
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) Lift-Type Mower - To disconnect the mower, first extend the tractor 3-point 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.
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: • 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 13.1 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 Use adequately sized and rated trailers and equipment to transport the tractor and implement.
