In order to reduce accidents and enhance the safe operation of mowers,
Alamo Group Ag Division,
in cooperation with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower Safety
Practices video and guide book.
The video will familiarize and instruct mower-tractor operators in safe practices when using industrial and agricultural mowing equipment. It is important that Every Mower Operator be educated in the operation of their mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This video, along with the mower operator’s manual and the warning messages on the mower, will significantly assist in this important education.
Your Authorized

If you lose or damage this manual a free replacement manual can be obtained from an authorized Rhino Ag dealer or by down loading the manual from the Rhino Ag website www.servis-rhino.com
BEFORE YOU START! READ, UNDERSTAND, and FOLLOW the information provided in this manual, the AEM
Mower Safety manual and the tractor operator's manual carefully to learn how to operate and service your machine properly. Failure to do so could result in personal injury to you and bystanders. All implements with moving parts are potentially hazardous. Every effort has been made to ensure that the machine is safe but operators must avoid engaging in unsafe practices and follow the written instructions provided. The manufacturer has designed this implement to be used with all its safety equipment properly attached to minimize the chance of accidents.
SAFETY FIRST. Completely read and understand the safety section of this manual before operating this equipment. Do not allow anyone to operate this equipment who has not fully read and understood this manual.
Contact your Dealer to explain any instructions that you do not fully understand.
The care you give your Rhino Ag Implement will greatly determine your satisfaction with its performance and its service life. Carefully read and follow the instructions in this manual to provide you with a thorough understanding of your new implement and its intended use and service requirements.
All references made in this manual to right, left, front, rear, top or bottom are as viewed facing the direction of forward travel with the implement properly attached to the tractor.
Replacement Parts information is located in a separate Parts Manual. Rhino Ag mowers use balanced and matched system components for blade carriers, blades, cuttershafts, knives, knife hangers, rollers, drivetrain components, and bearings. These parts are made and tested to Alamo Group Ag specifications. Non-genuine “will fit” parts do not consistently meet these specifications. The use of “will fit” parts may reduce mower performance, void warranties, and present a safety hazard. Use genuine Rhino Ag mower parts for economy and safety.
For future reference, record your Rhino Ag product model number and serial number.

Mower-Thrown Objects
Depending on the designed purpose, mowers are designed to cut grass, weeds, brush and crops. The mower blades have been designed and tested for rugged use. The mower blades, however, are not intended to contact solid objects like rocks, concrete or metal. Such impact can cause broken objects to be thrown up to 300 ft (92 m). Bystanders should never be within 300 ft (92 m) of an operating rotary mower or within 100 ft (30 M) of a properly equipped disc mower.
Operate Safely
Mower shielding is designed to reduce the risk of thrown objects and must be properly maintained and in place during mowing operations.
The risk of serious injury or death from thrown objects can be signifi cantly reduced by following three rules.
If all of these safety rules are not followed, the mowing operation must be stopped if anyone comes within the safety limit for the mower type.
First
— Inspect the area prior to mowing and remove stones, branches, wire, cable, metal, glass and other solid objects before operating. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator.
In non-crop areas with grass and weeds high enough to hide objects that could be struck by the blades, inspect the area and remove or mark large debris or obstacles.
Mow the area at an intermediate height. Inspect the area closely and remove or mark any remaining debris or obstacles. Mow again at desired fi nal height.
Follow
All Mower
Safety Rules
Second
— Mower-thrown object shielding must be used when operating near roads, parks, populated areas or other areas where thrown objects could injure bystanders or damage property. Follow the manufacturer's operator's manual.
Third
— Cross diagonally when mowing through ditches, sharp dips, and drops. Raise the mower to prevent the mower blades from hitting the ground.

Operate Safely
Mower-Thrown Objects (continued)
Disc Mowers
— When using a disc mower it is important to know the area to be mowed. If the operator has mowed the fi eld before and is familiar with all obstacles that may be present, it is suffi cient to watch ahead of the mower path for any additional objects that may have entered the fi eld. Be ready to stop or avoid any objects that could be hazardous if thrown by the mower. If you plan to mow an unfamiliar fi eld and it is next to a traveled road or people may be within 100 ft (30 m) of the mower you must inspect, and clean or mark the fi eld.
Mowing In Reverse
Do not mow while traveling in reverse. Objects are more likely to be thrown and can travel further.
Shut off the PTO, wait for the blades to stop turning, raise the mower, and then back up.
Mow traveling in the forward direction.
Do Not Mow in Reverse
Use Proper
Ground Speed
Mowing Ground Speed
Proper ground speed depends on terrain conditions and grass type, density and height to be cut:
— Normal ground speed range is 2 to 5 mph.
— Use slower ground speed for mowing tall, dense grass.
— Use faster ground speed for mowing medium height, thin grass and under smooth terrain conditions.
— Use slower ground speed for mowing in rough, sloping or unfamiliar terrain.
Disc mowers are designed to use faster ground speeds for operating in fi elds clear of debris and surface hazards.
Operate Safely
Extremely Tall Grass Mowing
You may need to mow extremely tall, non-crop grass twice. (See page 13,
Mower-Thrown Objects.
)
First mowing pass:
— Shut the mower and tractor down using proper equipment shut down practice before dismounting tractor. (See page 18,
Proper Equipment Shut Down
Practices.
)
— Inspect the area and remove or mark debris and obstacles.
— Cut grass higher (10-15 inches) to avoid hidden objects.
Second mowing pass:
— Shut the mower and tractor down using proper equipment shut down practice before dismounting tractor.
— Inspect the area and remove or mark debris and obstacles.
— Cut grass at desired height and, when possible,
90 degrees to the fi rst mowing pass.

Mower Blade Maintenance
Do not take chances using damaged or bent blades.
The mower manufacturers from the Association of Equipment Manufacturers (AEM) and the Farm
Equipment Manufacturers Association (FEMA) advocate that you DO NOT reuse, straighten, hard face or weld mower blades. Death or serious injury could result if a broken blade is thrown from a mower.
25
Perform Maintenance Safely
Mower Blade Maintenance (continued)
—
How are mower blades made?
Mower blades are made of high strength alloy spring steel. They are hot-forged and shaped to meet the manufacturer’s individual specifi cations, then heat treated and tempered to a high strength, ductile state to reduce the possibility of breaking while mowing.
Blades are tested to ensure they meet strength, hardness, and ductility standards. If a blade fails to meet any of these specifi cations, it will not be used on the mower.
—
What happens when a mower blade bends?
It takes a great amount of impact force to bend the blade. This impact force often results in the blades being gouged or chipped. After a blade is damaged by a gouge or chip a blade failure is much more likely to occur. When a blade is severely bent, a microscopic crack may be created in the blade. Straightening the blade does not remove or repair this crack, but may cause additional cracks.
Additional stresses during mowing operations can result in an unexpected blade failure.
—
Avoid bending blades.
Help prevent mower blades from bending or cracking by avoiding contact with solid objects. Mower blades are intended to cut grass, shrubs, woody vegetation, and small trees and limbs. They are not intended to contact solid objects such as rocks, concrete, or steel posts. Inspect the area prior to mowing. Remove or clearly mark any solid objects and mow around them.
—
Replace damaged blades!
Inspect the mower blade(s) daily or after hitting any solid object. If a mower blade becomes damaged (bent, gouged, cracked) or worn more than 25 percent of the original size, it should be removed and replaced with a new blade. Always use the original manufacturer’s blades. Aftermarket brand blades may not meet the mower manufacturer’s strength, hardness and ductility requirements.
—
Do not take chances mowing with damaged or bent blades.
Using a damaged or straightened mower blade can result in the blade breaking and being thrown into the operator or a bystander causing death or serious injury. The price of a new blade is small compared to the potential for the serious injury that could result from a bent or broken blade being thrown from the mower.

Objetos arrojados por la cortadora de césped
Dependiendo del propósito previsto, las cortadoras están diseñadas para cortar hierba, maleza, broza y cultivos. Las hojas de la cortadora están diseñadas y probadas para uso intensivo. Las hojas de la cortadora, sin embargo, no están diseñadas para entrar en contacto con objetos sólidos como rocas, cemento o metales. Un impacto de este tipo puede arrojar objetos rotos hasta
300 pies (92 m) de distancia. Nunca debe haber personas ajenas a menos de 300 pies (92 m) de una cortadora giratoria en funcionamiento o a menos de 100 pies (30 m) de una cortadora de disco correctamente equipada.
Operación con seguridad
Los escudos de la cortadora están diseñados para reducir el riesgo de objetos arrojados y se deben mantener correctamente y en su lugar durante las operaciones de corte.
El riesgo de lesiones graves o muerte puede reducirse signifi cativamente si se siguen estas reglas.
Si no se siguen todas estas reglas de seguridad, la operación de corte debe detenerse en caso de que alguna persona ingrese dentro del límite de seguridad correspondiente a cada tipo de cortadora.
Primero
— Inspeccione la zona antes de cortar y retire las piedras, ramas, alambres, cables, metales, vidrios y otros objetos sólidos antes de hacer funcionar la máquina. Los objetos que no puedan retirarse deben marcarse con claridad y ser evitados con cuidado por el operador.
En áreas sin cultivos con hierba y maleza de altura sufi ciente como para ocultar objetos que podrían ser golpeados por las hojas, inspeccione la zona y retire o marque los residuos u obstáculos grandes.
Siga todas las reglas de seguridad
Realice el corte de la zona a una altura intermedia.
Inspeccione la zona atentamente y retire o marque cualquier residuo u obstáculo restante. Corte nuevamente a la altura fi nal deseada.
Segundo
— Los escudos para objetos arrojados por la cortadora deben usarse cuando se opera cerca de caminos, parques, zonas pobladas u otras zonas donde objetos arrojados podrían lesionar a personas ajenas o dañar la propiedad. Siga el manual del operador del fabricante.
Tercero
— Cruce en sentido diagonal cuando realiza el corte a través de zanjas, depresiones marcadas y hundimientos. Eleve la cortadora para evitar que las hojas de la cortadora golpeen el suelo.

Cortadoras de disco
— Cuando se usa una cortadora de disco, es importante conocer la zona donde se va a cortar. Si el operador ha realizado cortes en el terreno antes y está familiarizado con todos los obstáculos que puede haber, es sufi ciente observar delante de la trayectoria de la cortadora para detectar cualquier objeto adicional que pueda haber ingresado en el terreno. Esté preparado para detenerse o evitar objetos que podrían ser peligrosos si son arrojados por la cortadora. Si piensa cortar en un terreno que no conoce bien y se encuentra junto a un camino transitado o puede haber personas a menos de 100 pies (30 m) de la cortadora de césped, debe inspeccionar y limpiar o marcar el terreno.
Apague la TDF, espere que las hojas dejen de girar, eleve la cortadora y, después, retroceda.
Corte desplazándose en sentido de avance.
Use la velocidad de desplazamiento correcta
Cómo cortar en retroceso
No corte mientras se desplaza en retroceso. Es más probable que se arrojen objetos y que éstos puedan llegar más lejos.
No corte en retroceso
Velocidad de desplazamiento durante el corte
La velocidad de desplazamiento correcta depende de las condiciones del terreno y del tipo de hierba, la densidad y la altura que debe cortarse:
— El rango normal de velocidad de desplazamiento es de
2 a 5 mph (3.2 a 8 km/h).
— Use una velocidad de desplazamiento menor para cortar hierbas altas y densas.
— Use una velocidad de desplazamiento mayor para cortar hierba delgada a altura media y con condiciones de terreno sin difi cultades.
— Use una velocidad de desplazamiento menor par acortar en terreno irregular, con pendientes o no muy conocido.
Las cortadoras de disco están diseñadas para usar velocidades de desplazamiento mayores cuando funcionan en terrenos despejados de residuos y peligros superfi ciales.

Revise los neumáticos y las ruedas a diario porque la estabilidad del tractor y la cortadora de césped puede verse signifi cativamente afectada por la presión de los neumáticos o daños en los neumáticos o en las ruedas.
Revise los neumáticos para verifi car:
— La presión correcta.
— Cortes y protuberancias.
— Clavos u otras pinchaduras.
— Desgaste desparejo o excesivo.
— Estado de los vástagos y tapas de las válvulas.
Revise las ruedas para verifi car:
— Daños en las llantas.
— Tuercas o pernos faltantes o fl ojos.
— Desalineación.
Todos los servicios de neumáticos deben ser realizados por un centro de servicios para neumáticos cualifi cado o por una persona de servicio autorizada debidamente capacitada en los procedimientos y el uso del equipo de seguridad destinado a los servicios de neumáticos.

¡ADVERTENCIA! Los tipos de ruedas y neumáticos que generalmente se encuentran en estos equipos requieren cuidados especiales al realizar servicios para evitar lesiones graves o la muerte.
No infl e los neumáticos por encima de la presión recomendada. Asegúrese de volver a colocar el lastre de los neumáticos si está instalado. Consulte las especifi caciones del fabricante para ver los requisitos de lastre.
Mantenga las tuercas de las ruedas apretadas según las recomendaciones del fabricante.
Es normal que la presión de los neumáticos aumente durante el funcionamiento; NO se debe reducir.
Nunca vuelva a infl ar un neumático que se ha desinfl ado mucho o por completo sin retirar el neumático de la rueda. Haga inspeccionar atentamente el neumático y la rueda para detectar daños antes de volverlos a armar.
Al agregar aire a un neumático, hágalo desde cierta distancia. Use una manguera larga con mandril de autofi jación. Siempre párese detrás de la trocha cuando ajusta la presión de un neumático.
Evite la explosión de los neumáticos
No infl e neumáticos con gases infl amables o con sistemas que usan un inyector de alcohol.
Nunca corte o suelde una rueda con un neumático infl ado instalado en ella. Esto podría causar descompresión explosiva.
Verifi que que el tamaño del neumático y la rueda coincidan correctamente.
Cuando reemplaza neumáticos, asegúrese de que sean de la clasifi cación adecuada especifi cada por el fabricante.
Los neumáticos no deben funcionar a velocidades más altas que las nominales. La mayoría de los neumáticos para agricultura están clasifi cados para una velocidad máxima de 20 mph (32 km/h).
Realización de mantenimiento con seguridad
Servicio y reparaciones completas antes de liberar la máquina
Apriete todos los pernos, accesorios y conexiones con las torsiones especifi cadas por el fabricante.
Instale todas las guardas, cubiertas y escudos después de realizar los servicios. Reemplace o repare los que estén dañados. Llene y recargue los sistemas a presión sólo con los fl uidos aprobados o recomendados por el fabricante.
Arranque el motor y revise para detectar fugas. (Consulte la página 23,
Riesgos del sistema hidráulico
.) Haga funcionar todos los controles para asegurarse de que el tractor y la cortadora de césped funcionan correctamente.
Pruebe la máquina si es necesario. Después de las pruebas, apague y verifi que el trabajo realizado. ¿Falta algún pasador, arandela, tuerca de seguridad, etc.?
Vuelva a revisar todos los niveles de fl uidos antes de liberar la máquina para el funcionamiento.
Todas las piezas deben ser inspeccionadas durante la reparación y deben reemplazarse si están gastadas, rajadas o dañadas. Las piezas excesivamente gastadas o dañadas pueden fallar y causar lesiones o la muerte.
Reemplace cualquier letrero dañado o ilegible.
Verifi que el trabajo de servicio cuando está completo
Mantenimiento de las hojas de la cortadora
No corra riesgos usando hojas dañadas o dobladas. Los fabricantes de cortadoras de césped de la Asociación de Fabricantes de Equipos (Association of Equipment
Manufacturers, AEM) y la Asociación de Fabricantes de
Equipos para Agricultura (Farm Equipment Manufacturers
Association, FEMA) piden que las hojas de cortadoras
NO se reutilicen, enderecen, refuercen en su superfi cie o suelden. Si una hoja rota es arrojada por una cortadora, podrían producirse lesiones graves o la muerte.

—
¿Cómo están hechas las hojas de la cortadora de césped?
Están hechas acero para resortes de aleación de alta resistencia. Se forjan en caliente y se les da forma para cumplir con las especifi caciones individuales del fabricante; luego, se tratan y templan a un estado dúctil, de alta resistencia para reducir la posibilidad de rupturas durante el corte. Las hojas se prueban para garantizar que cumplan con las normas de resistencia, dureza y ductilidad. Si una hoja no cumple con alguna de estas especifi caciones, no se utilizará en la cortadora de césped.
—
¿Qué sucede cuando se dobla una hoja de la cortadora?
Se necesita una gran fuerza de impacto para doblar la hoja. Esta fuerza de impacto a menudo resulta en que las hojas se agujerean o marcan. Una vez que una hoja está dañada por un agujero o una marca, es mucho más probable que ocurra una falla de la hoja. Cuando una hoja está gravemente doblada, puede crearse una rajadura microscópica en ella.
Enderezar la hoja no quita o repara esta rajadura, sino que puede causar rajaduras adicionales.Tensiones adicionales durante los trabajos de corte pueden resultar en una falla imprevista de la hoja.
—
Evite doblar las hojas.
Contribuya a prevenir que las hojas de la cortadora se doblen o rajen evitando el contacto con objetos sólidos. Las hojas de la cortadora de césped están destinadas a cortar hierba, arbustos, vegetación leñosa y árboles y ramas pequeños. No están diseñadas para entrar en contacto con objetos sólidos como roca, cemento o postes de acero.
Inspeccione la zona antes de usar la cortadora. Retire o marque claramente los objetos sólidos y corte alrededor de ellos.
—
Sustituya las hojas dañadas!
Inspeccione las hojas de la cortadora diariamente o después de golpear algún objeto sólido. Si una hoja de la cortadora de césped se daña (está doblada, agujereada, rajada) o desgasta más del 25 por ciento del tamaño original, debe retirarse y sustituirse con una nueva. Siempre use las hojas originales del fabricante. Las hojas de marcas no originales pueden no cumplir con los requisitos de resistencia, dureza y ductilidad del fabricante de la cortadora.
—
No corra riesgos usando hojas dañadas o dobladas.
El uso de una hoja de cortadora dañada o enderezada puede resultar en la ruptura de la hoja y que la hoja sea arrojada hacia el operador o una persona ajena causando una lesión grave o la muerte. El precio de una nueva hoja es bajo en comparación con la posibilidad de una lesión grave que podría resultar de una hoja doblada o rota arrojada por la cortadora

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. Understand what each control is for and how to use it.
Rhino typically offers three types of shielding to protect the operator, passerby, livestock, and property from thrown objects... deflectors, single chain guards, and double chain guards. Shielding should be selected based on the intended use of the mower. Double chain guards or deflectors should be used for highway, right-of-way, parks or greenbelt mowing or all other mowing where human dwellings, vehicles, or livestock could be within
300 feet of the mower. Chain guards are more durable, provide a longer service life and require less maintenance and replacement than deflectors. Single chain guards may be sufficient for agriculture and other mower use only where passersby or property are not within 300 feet of the mower during operation.
No shielding is 100% effective in preventing thrown objects. The possibility of injury and property damage from this hazard can be substantially reduce by selecting proper shielding, maintaining the mower and shielding in good operational condition, inspecting the area for foreign debris before mowing, operating the mower at a minimum cutting height of 4", and keep unprotected persons at a minimum distance of 300 feet from the mower at all times during operation.
Safety is of primary importance to the owner/operator and to the manufacturer. Observe all safety precaution decals on the machine and noted throughout the manual for safe operation of implement. If any assistance or additional information is needed, contact your authorized Rhino dealer. The owner/operator/dealer should know and understand the Safety Messages before assembly and be aware of the hazards of operating this cutter during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced when operating this machine.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR
INJURY.

INTRODUCTION
KEY OPERATION POINTS
• Cutting performance and distribution are best when cutter is level from side to side and front to rear.
• Never operate the Mower below full PTO speed of 540.
• Corn should be cut at 5 to 6 mph. If full PTO rpm cannot be maintained, use one lower gear.
Operating Noise Level/Sound Pressure
The sound levels at the operator's ear from the attached machine (rotary cutter) are at least 10 dB(A) below the levels from typical Agricultural tractors used to power and transport this machine. Therefore, the Noise emission values given by the OEM of the Agricultural tractor used to power and transport this machine would be valid when this machine is attached to and operated by that Agricultural tractor in all OEM recommended applications.

OPS-U- 0004
10 Twister Series 11/16
© 2017 Alamo Group Inc.
Operation Section 4-4
OPERATION
2.3 Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the TW14 mower requires a tractor with at least 15 HP, the TW15 at least 20 HP and the TW16 at least 25 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding recommended HP may cause mower damage by overpowering the unit in heavy cutting conditions.
2.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least 410 lbs for TW14, 475 lbsTW15 and 550 lbs for TW16. The TW14, TW15, and TW16 mowers are designed to be mounted on a tractor with a
CAT I 3-Point hitch. Refer to the tractor operator’s manual for the category of the tractor being used. If the hitch does not conform to ASABE CAT I dimensions, the mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount non-conforming hitches.
Depending on the hitch category, certain size pins are used to attach the mower to the tractor. CAT I hitches require 7/8” lower and 3/4” upper diameter hitch pins.
2.5 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 20 or 21-spline shaft.
NOTE:
The mower will not operate on tractors equipped with a 1000 RPM 21-spline or 1000 RPM 20-spline, 1-
3/4” shaft.
Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more than one speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an overrunning clutch must be used between the PTO output shaft and the driveline of the mower. An authorized tractor dealer can provide the over-running clutch and its installation if needed.
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. Consult an authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
10 Twister Series 11/16

Operation Section 4-5
OPERATION
Never operate the Tractor and Mower if the Implement input driveline is directly connected to the Tractor transmission. Tractor braking distances can be substantially increased by the momentum of the rotating Mower blades driving the Tractor transmission even though the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
(S3PT-16)
Do not connect the PTO driveline to the tractor or operate the implement unless the implement is securely connected to the tractor.
2.6 Tire Spacing
Tractor tires should be set a minimum of 60” (1.5
m) apart measured from inside of tire to inside of tire, or maximum width possible. Refer to the tractor Operator’s Manual or consult an authorized dealer for instructions to change tractor tire spacing.
OPS-R- 0062
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
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)
3.1 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.
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. It is the operator’s responsibility to forbid all extra riders at all times.

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.
OPS-R-0001
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)
5.1 Connecting the Mower
1. Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid interference when raising and lowering the mower.
3. Board the tractor and start the engine. Position the tractor to the mower with the 3-point lift arms positioned at the same height and to the outside of the mower hitch pins.
NOTE:
Set the 3-point lift control to “Position
Control” so that the lift arms maintain a constant height when attaching the mower. See the tractor Operator’s Manual for correct settings when attaching 3-point equipment.
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. Walk around to opposite side and repeat procedure for remaining lift arm and hitch pin.
7. Extend or retract 3-point top link to align its end hole with the holes of the mower’s top link.
Insert the top link hitch pin and insert retaining pin into hitch pin.
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.

Operation Section 4-9
OPERATION
5.2 Safety Tow Chain
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.
After connecting both ends of the safety chain, drive the tractor to the right and left to check for proper chain length. Adjust length as necessary and allow only enough slack in the chain to make a maximum turn in both directions. When not in use, store the safety chain to protect it from mud or standing water by wrapping the chain around the tongue. Replace the safety chain if one or more links or end fittings are broken, stretched or otherwise damaged or deformed.

Ops-0008-MISC
6. SETTING THE MOWER
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven terrain.
NOTE:
Avoid very low cutting heights, striking the ground with the blades gives the most damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height which causes the blades to contact the ground.
OPS-U- 0010
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)
10 Twister Series 11/16
© 2017 Alamo Group Inc.
Operation Section 4-10
OPERATION
6.1 Setting Mower Height- Lift Type - (Standard or Quick Hitch)
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. Set the 3-point control lever stop at this position to maintain this height when raising and lowering the mower.
3. Shut down the tractor and remove the key.
4. Adjust the mower deck front to rear by extending or retracting the 3-point top link.
Always set front of deck 3/4” lower than rear for best performance.
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 adjusting fasteners securing the tailwheel frame in position and allow the tailwheel to rest on ground level. Align tailwheel frame between nearest sets of holes in adjustment strap and reinstall adjustment fasteners. Tighten all bolts and nuts.
8. Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2-1/2” before the tailwheel leaves the ground. This will allow the mower to follow the contour of uneven terrain.

Operation Section 4-11
OPERATION
6.2 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.
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.
OPS-U-0041_B
7. 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. Push the driveline yoke onto the
PTO shaft, release the locking collar, and position the yoke until the locking collar balls are seated onto the PTO shaft. Push and pull the driveline back and forth several times to ensure a secure attachment.
OPS-R-0003_A
10 Twister Series 11/16
© 2017 Alamo Group Inc.
Operation Section 4-12
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)
7.1 Driveline Length Check
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.
(S3PT-18)
When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most compressed position, the profiles do not ‘bottom out’, and when at its farthest extended position, there is sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1” clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a minimum profile engagement of 9” must be maintained.
“Bottoming Out” Check Procedure
• Disconnect driveline from the tractor and slide the profiles together until fully compressed.
• Place a mark on the inner shield 1/8” from the end of the outer shield.
• Reattach the driveline to the PTO Shaft.
• Raise the mower. Drive through a typical ditch which the unit may encounter and watch marks on the driveline. If the distance between the mark and the outer shield becomes less than 2” at any point there is a potential problem bottoming out the driveline and the driveline should be shortened.
OPS-R-0004_F
10 Twister Series 11/16
© 2017 Alamo Group Inc.
Operation Section 4-13
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.
• Pull driveline apart and reattach yoke to PTO shaft.
• Hold driveline sections parallel to one another and measure back 1” from yoke of each shaft and place mark on opposite section. Cut this length off with a saw.
• Round off all sharp edges and debur.
• Thoroughly grease then reinstall the driveline.
• Recheck for proper operation.
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.
• Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline profiles were engaged.
• If the engaged length is less than 9”, the shaft is considered too short and should be replaced with a longer shaft. Consult an authorized dealer to purchase the required driveline length.
NOTE:
When raising the mower, at least 1” clearance must be maintained between the driveline and the mower deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the mower can be raised. OPS-R-0005_E
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. By performing a thorough pre-operation inspection and service, valuable down time and repair cost can be avoided.
OPS-U-0029
Always disconnect the main PTO Driveline from the Tractor before performing service on the Implement. Never work on the Implement with the tractor PTO driveline connected and running. Rotating Parts, Blades or Drivelines could turn without warning and cause immediate entanglement, injury or death.

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.
OPS-U- 0012
Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health.
(SG-23)
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. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly to determine the stopping characteristics of the Tractor and Implement. As you increase the speed of the Tractor the stopping distance increases. Determine the maximum transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after you determine that the equipment can be operated at a higher speed. Use extreme care and reduce your speed when turning sharply to prevent the tractor and implement from turning over. Determine the maximum turning speed for you and this equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your speed. When operating in traffic always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.

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.
OPS-U-0033
9.2 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. When engaged the differential lock will prevent or limit the tractor from turning. During normal cutting conditions, locking the differential provides no benefit and should not be used.
OPS-
U- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases; use extreme care and reduce your speed in these conditions. When operating in traffic, always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.

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. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the mower can be raised to avoid driveline damage
.
OPS-R-0042
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. If the power steering or engine ceases operating, stop the tractor immediately as the tractor will be difficult to control.
Perform turns with the tractor and mower at slow speeds to determine how the tractor with an attached mower handles a turn. Determine the safe speed to maintain proper control of the tractor when making turns. When turning with a towed implement, the overall working length of the unit is increased. Allow additional clearance for the mower when turning.
To avoid overturns, drive the tractor with care and at safe speeds, especially when operating over rough ground, crossing ditches or slopes, and turning corners. Tractor wheel tread spacing should be increased when working on inclines or rough ground to reduce the possibility of tipping.
Use extreme caution when operating on steep slopes. Keep the tractor in a low gear when going downhill. DO NOT coast or free-wheel downhill.

Operation Section 4-27
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). This type of abusive operation can cause serious damage to the tractor and mower drive by pushing the PTO into the tractor and through the support bearings or downward onto the PTO shaft, breaking it off.
Damage resulting from over-collapse of the driveline’s inner profile and its outer housing may allow the driveline to come loose from the Tractor which could cause bodily injury to the operator or bystanders and/or extensive damage to the Tractor or Implement.
OPS-R-0020
When confronted with an incline or ditch, do not approach from an angle which is perpendicular or straight on as damaged to over collapse of the driveline may occur.
When crossing such terrain, the implement should be fully lowered for a lower center of gravity and added stability.
OPS-R-0021
10 Twister Series 11/16
© 2017 Alamo Group Inc.
Operation Section 4-28
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.
When operating the tractor and mower across slopes and inclines, through ditches, and other uneven terrain conditions, it is important to maintain sufficient deck to ground clearance. Blade contact with the ground may cause soil, rocks and other debris to be thrown out from under the mower resulting in possible injury and/or property damage.
Ground contact also produces a severe shock load on the mower drive and to the mower blades resulting in possible damage and premature wear.
OPS-R-0022
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.
The operator must read and understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
OPS-U- 0015
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 Section 4-29
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)
10.1 Foreign Debris Hazards
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. Wait for all mower rotating motion to stop, then raise the mower and move the tractor and implement off the object. Inspect the area and remove, or mark the location of the debris. Inspect the condition of the mower and make any needed repairs immediately.
Make sure the blades are not damaged and the carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and only operate the tractor and mower with the ROPS in the raised position. If the tractor or mower hits a tree stump, rock, or bump, a sudden movement could throw you off of the seat and under the tractor and/or mower. The seat belt is your best protection from falling off the tractor and the ROPS provides protection from being crushed during a tractor roll-over.
OPS-R-0023
Remove Foreign Material
Raise Mower over solid objects
10.2 Bystanders/Passersby Precautions
If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once, idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the
300 foot distance.
OPS-R-0024
10 Twister Series 11/16

Operation Section 4-30
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;
-Mower sections or Wings are running close to and parallel to the ground without exposed
Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general debris has been removed.
NOTE:
Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area should be: inspected and large debris removed, mowed at an intermediate height, inspected, closely with any remaining debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and make the final cut more uniform).
(SRM-01)
10.3 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the implement to determine the cause of the noise or vibration and repair the abnormality.
OPS-U- 0027
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)
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.
(SGM-09)
10 Twister Series 11/16

Operation Section 4-31
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. 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. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.
If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The operator may be required to experiment with several gear range combinations to determine the best gear and range which provides the most ideal performance from the mower and most efficient tractor operation. As the severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to maintain the proper operating PTO speed.
OPS-R-0025
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.
(SG-26)
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.
(SGM-07)
10.5 Operating the Mower
Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must be equipped with a ROPS in the raised position or a ROPS cab.
The mower is designed to cut vegetation up to 1” in diameter. Sharp blades will produce a cleaner cut and require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern that provides the maximum pass length and minimizes turning.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to access areas to be cut, make sure there are no persons or other foreign debris behind the mower before mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to ensure tractor and mower control is maintained.

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. 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.
(SGM-1)
Avoid mowing in reverse direction when possible. Check to make sure there are no persons behind the mower and use extreme care when maneuvering 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)
Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck.

Operation Section 4-33
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. Sharp turns can cause premature failure of the joints and place pressure on the tractor PTO shaft and could cause extensive mechanical damage to the mower and tractor.
OPS-R-0027_A
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.

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.
• Lubricate all mower grease points and fill gearbox oil levels as detailed in the maintenance section.
• Tighten all bolts and pins to the recommended torque.
• Check the mower for worn and damaged parts. Perform repairs and make replacements immediately so that the mower will be ready for use at the start of the next season.
• Store the mower in a clean, dry place with the mower housing resting securely on blocks or at ground level.
• Keep the driveline yoke from sitting in water, dirt and other contaminants.
• Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.
It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If the mower has been exposed to such conditions, at the start of each mowing season, and any time it is suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal
Clutch Maintenance of the maintenance section in this manual.

13.1 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.
Check your side view mirrors frequently and remember that vehicles will approach quickly because of the tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a public road.
OPS-U- 0019
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When transporting the

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.
OPS-U- 0020
Make sure that all tractor flashing warning lights, headlights, and brake/tail lights are functioning properly before proceeding onto public roads. While newer model tractors have plenty of lighting to provide warning signals and operating lighting, most older models are only equipped with operating lights.
Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models.
OPS-U- 0021
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.

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. 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. 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.
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.
While hauling the tractor and implement, make occasional stops to check that the tractor and implement have not moved or shifted and that the securing chains have maintained tension. If during transport a hard braking, sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of the load.

. The chart gives the frequency of lubrication in hours, based on normal operating conditions. Severe or unusual conditions may require more frequent lubrication
.
Use Multi-Purpose Gear Oil when required in Gearbox. Use N.L.G.I #2 grease for all locations designated with grease gun. Be sure to clean the fitting thoroughly before using grease gun. Failure to maintain proper lubrication will result in damage to U-joints, gearbox, and/or driveshaft.

GEARBOX
The gearbox should be full (18 ounces) 0.54 liters and not require additional lubricant unless the box is cracked or a seal is leaking. It is recommended that the hex oil level check plug be removed to check oil level after every 8 hours of operation. If required, oil should be added until it runs out hole.
Recommended lubricant is EP85W-140 Gear Oil.
NOTE
: Make sure mower is level when checking oil in the gearbox.
Gearbox capacity is 18 oz.
NOTE
: Overfilling of Gearbox will cause pressure to build up and cause Grease Seals to leak.
DRIVELINE LUBRICATION
Grease Fittings are located on the Cross Assembly of each U-Joint and on the telescoping tubes.
Grease the U-Joint after each 8 hours of use
(Figure MntP-R-0021)
. Do not force grease through the Needle Cup Assemblies. Grease the telescoping tubes after every 8 hours of use. To grease profile tube, disconnect drive from PTO and pull halves apart. Pump grease into outer profile tube and reinstall together. Lube slide Collar weekly with WD40 or equivalent weight oil.
The Driveline Integral Shields should not become dented or otherwise damaged. The Integral Shield Assembly has a Nylon Bearing at each end and should turn freely. This nylon bearing should require lubrication every 40 hours. To remove the Integral Shields for replacement or repair, turn the three Nylon Nuts 1/4 turn in the Shield
Slots of the Cone and Tube and remove them. Slip the Shield Cone Assembly off inner section of the Driveline.
Install the new or repaired Shield on the Driveline. Place the split Nylon Bearing over the Driveline Housing of
Shaft against the Yoke and in the Bearing groove. Install shield over the Housing so the Nylon Bearing fits into the Shield Bearing Retainer. Align a slot in the Shield Cone with on of the slots in the Shield. Put one of the
Nylon Nuts back in through the aligned slots and turn until it is perpendicular to the slots. Add the other two
Nylon Nuts.
Make certain that the Driveline Integral Shields are free to telescope and rotate around the driveline without binding.

IMPORTANT: Scan this QR Code with your smart phone to link to the ADMA
Driveline Safety Manual for more information on the safe use of a driveline during normal operation and maintenance. Or type in your internet browser the following web address: www.algqr.com/dme
Ops-0009-MISC
SHEAR PIN YOKE
Yoke is supplied with a grease fitting to lube between gearbox shaft and yoke. This allows yoke to spin freely on gearbox shaft when pin shears.
Failure to lube may cause yoke to gall and spin weld to shaft. Adding even small amounts of grease will greatly prolong life of yoke. The shear bolt (1/2” x 3”) MUST BE a Grade 2 to ensure that it shears when high torque load is encountered.

Maintenance Section 5-6
MAINTENANCE
SLIP CLUTCH
If a slip clutch is incorporated in the PTO driveline, it is designed to slip, absorb the shock load, and protect the driveline.
After the first hour of operation, the slip clutch should be checked for overheating. After this first check, the slip clutch should be checked weekly or anytime there is overheating. To adjust the slip clutch, tighten the spring nuts 1/8 (maximum) turn at a time. Bolts should NEVER be adjusted to the point where the springs are compressed solid.
The slip clutch should be checked periodically and adjusted to compensate for wear. The lining plates are 1/8” thick when new. Replace after 1/32” wear. If the mower has been idle for an extended period of time, or in wet weather, before operating check to make sure the friction lining plates are not frozen or rusted together. Should this freezing occur, refer to the procedure described in “Seasonal Clutch Maintenance”.
There are two friction lining plates in the slip clutch. These should be checked weekly for oil or grease, wear, and moisture which could cause corrosion on the drive plates.
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.
(SGM-3)
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)

MAINTENANCE
SEASONAL CLUTCH MAINTENANCE
It is important that the clutch lining plates slip when an obstacle or load heavier than the clutch setting is encountered. Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or humid air it is important to make sure that the clutch lining plates are not rusted/corroded together. Before operating the mower use the following procedure to make sure the clutch will slip and give the overload protection required.
1. Loosen nuts
(Figure Mnt-R-0082)
on springs until the springs can freely rotate, yet remain secure on bolts.
Tighten nut until there is a small amount of pressure on plates.
2. Mark outer plates as shown in
Figure Mnt-R-0082
.
3. Attach mower to tractor and start the tractor. Set the engine speed at 1200 RPM.
4. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates should break loose (check the mark).
5. Turn tractor off and tighten the nuts on the springs to their standard compressed length.
Note:
The clutch is equipped with either 31 mm or 35 mm length uncompressed springs. Determine the equipped springs for your mower and refer to
Figure Mnt-R-0082
to determine the Standard and Maximum
Compressed length for proper clutch adjustment.

MAINTENANCE
BLADE SERVICING
Inspect blades before each use to determine that they are properly installed and in good condition. Replace any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out when sharpening.
Use only original equipment blades on this cutter. They are made of special heat-treated alloy steel. Substitute blades may not meet specifications and may fail in a hazardous manner that could cause injury.
Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR
WELD ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE
BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM
THROWN BLADES.
(SGM-10)
• Manually wiggle the blade carriers to check for any looseness.
• Retighten any loose parts.
• Recheck torque every 50 hours.
Operating with loose blade hardware will damage the blade holder and blades. Whenever the blades have been removed or replaced, the hardware must be retightened after the first eight hours of operation. On new units check blade hardware and the blade nut torque after first 8 hours.
Operating with loose blade holder will damage the blade holder and output shaft, two initial tightenings are required. Retighten after one hour and again after the day of operation. In severe cutting conditions or commercial use, a daily inspection is required.
To help prevent structural damage caused by loose hardware, tighten gear case hardware as specified. Check torque after first 8 hours of use and every 50 hours thereafter.
NOTE:
Correct Blade Rotation is counter-clockwise viewed from the top.
Inspect Blades daily for normal wear. If Blades have a notch worn into the leading worn into the leading edge at the lower bend more than
1/2” DEEP
(due to running in gravel and/or the ground),
REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY.
Failure to replace such abnormally worn blades may lead to catastrophic failure of the blade and ejection of the broken part with tremendous force which may cause bodily injury or death.
NOTE:
Replace Blades in pairs after no more than 1/2” notch wear.

Maintenance Section 5-9
MAINTENANCE
BLADE SHARPENING
When sharpening blades, grind each blade the same amount to maintain balance. Follow original sharpening pattern as shown in
Figure Mnt-R-0008.
Always sharpen blades by grinding. Always sharpen both blades at same time to maintain balance. The difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause excessive vibration which can damage gear box bearings. Vibration may also cause structural cracks in cutter housing. DO NOT heat and pound out edge. Do not sharpen blade to a razor edge, but leave a 1/16” blunt edge. Do not sharpen back side of blade.
Avoid personal injury. Always block the cutter up to prevent if from falling when the blades and/ or carrier are being serviced.
BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is not available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite end of bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process until carrier breaks loose.

Maintenance Section 5-10
MAINTENANCE
BLADE CARRIER INSPECTION
Blade bolt fit into blade carrier should be checked every time blades are changed. The blade bolt fit into carrier as a snug slip fit. If the blade bolt fit appears to be loose or sloppy, measure the hole in blade carrier. If the bottom of the hole is 1/16” or greater than the shank of the new blade bolt the blade carrier should be replaced.
The shoulder of the blade bolt should bottom out against the blade pan when assembled to allow the blade to swing when an object is struck during operation.
Failure to replace a worn blade carrier as described above may lead to catastrophic failure of the blade, blade bolt and/or blade bolt nut resulting in the ejection of the broken parts of from under the mower at tremendous speed and force which could result in serious bodily injury or death.

Maintenance Section 5-11
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 450 ft-lbs, strike the carrier near the hub several times with a heavy hammer to seat to hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.
Re-tighten the nut to 450 ft-lbs. Install cotter pin and spread.
Operating the mower with a loose blade pan or holder can damage the taper connection on the gearbox output shaft. To ensure proper seating between the blade holder and output shaft, check and tighten the retaining nut after the first day of operation. Recheck the blade carrier attachment each morning before operating. Grasp the carrier firmly with both hands and try to push and pull the carrier with one hand while pulling and pushing with the other hand to try to rock or oscillate the blade carrier. If the carrier is loose, re-tighten the retaining nut before operating the mower.
Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few hours of operation.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from falling.
BLADE REMOVAL
Remove lockwasher and nut from blade bolt through inspection hole in deck of mower near the gearbox to remove blades for sharpening or replacement. See Figure MntP-R-0057. Always replace lockwasher and nut when replacing blade bolt. When installing blades be sure and check blade bolt pivot diameter for wear.
Replace bolt if worn more than 1/4 inch at any point. Tighten nut to 600 ft. lbs.

Blade Bolt Inspection
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.
Failure to replace abnormally worn blade bolts may lead to catastrophic failure of the blades and ejection of the broken part which may cause serious bodily injury or death.
Always replace Blade Bolts with new bolts whenever replacing the Blades.

STORAGE
Your rotary cutter represents an investment from which you should get the greatest possible benefit. Therefore, when the season is over, the cutter should be thoroughly checked and prepared for storage so that a minimum amount of work will be required to put it back into operation for the next season. The following are suggested storage procedures:
1. Thoroughly clean the cutter.
2. Lubricate the cutter as covered in Maintenance Section.
3. Tighten all bolts and pins to the recommended torque.
4. Check the cutter for worn or damaged parts. Make replacements immediately.
5. Place driveline in storage position resting on bracket.
6. Store the cutter in a clean, dry place with the cutter housing resting on blocks.
7. Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the cutter.
PROPER TORQUE 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*
NOTE:
These values apply to fasteners as received from supplier, dry or when lubricated with normal engine oil. They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants are used. This applies to both UNF fine and UNC coarse threads.
