SAFETY SAFETY A safe and careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions. The first section of this manual includes a list of Safety Messages that, if followed, will help protect the operator and bystanders from injury or death.
SAFETY READ, UNDERSTAND, and FOLLOW the following Safety (SG-2) PELIGRO! Si no lee Ingles, pida ayuda a alguien que si lo lea para que le traduzca las medidas de seguridad. (SG-3) DANGER! Never operate the Tractor or Implement until you have read and completely understand this Manual, the Tractor Operator’s Manual, and each of the Safety Messages found in the Manual or on the Tractor and Implement. Learn how to stop the tractor engine suddenly in an emergency.
SAFETY SAFETY DANGER! Never allow children or other persons to ride on the Tractor or Implement. (SG-10) Falling off can result in serious injury or death. DANGER! Never allow children to operate or ride on the Tractor or Implement. (SGM-11) WARNING! Do not mount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped. (SG-12) DANGER! Start tractor only when properly seated in the Tractor seat.
SAFETY WARNING! WARNING! PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS! Tractors with or without an Implement attached can often be noisy enough to cause permanent hearing loss. We recommend that you always wear hearing protection if the noise in the Operator’s position exceeds 80db. Noise over 85db over an extended period of time will cause severe hearing loss. Noise over 90db adjacent to the Operator over an extended period of time will cause permanent or total hearing loss.
SAFETY SAFETY WARNING! Never attempt to lubricate, adjust, or remove material from the Implement while it is in motion or while tractor engine is running. Make sure the tractor engine is off before working on the Implement! (SG-20) WARNING! 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.
SAFETY NEVER use drugs or alcohol immediately before or while operating the Tractor and Implement. Drugs and alcohol will affect an operator’s alertness and coordination and therefore affect the operator’s ability to operate the equipment safely. Before operating the Tractor or Implement, an operator on prescription or over-the-counter medication must consult a medical professional regarding any side effects of the medication that would hinder their ability to operate the Equipment safely.
SAFETY SAFETY WARNING! 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.
SAFETY Avoid mowing in the 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 in the reverse direction that you have not inspected and removed debris or foreign material.
SAFETY SAFETY WARNING! Use extreme care when lowering or unfolding the implement’s wings. Make sure no bystanders are close by or underneath the wings. Allow ample clearance around the implement when folding or unfolding the wings. Use extreme caution around buildings or overhead power lines. (S3PT-5) CAUTION! To prevent tipping of implement when stored in folded position, use carrying wheels or adequate stands on center frame.
SAFETY Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue Jack for lifting the mower only. Overloading the Tongue Jack can cause failure with possible serious bodily injury or even death.

OPERATION Mower Standard Equipment And Specifications TWR-120 OPERATION TWR-180 Note: The mower must be equipped with either single or double chain guards at all times. Alamo Industrial recommends mowers be equipped with double chain guards for all mowing purposes. Single chain guards may be used for agriculture purposes only and are specifically not recommended for highway, right-of-way, parks or greenbelt mowing. TWR-180 / TWR-120 12/04 © 2004 Alamo Group Inc.
OPERATION 1. OPERATOR REQUIREMENTS Safe operation of the rotary mower is the responsibility of a qualified operator. A qualified operator has read and understands both the mower and tractor Operator Manuals and is experienced in tractor and mower operations and all associated safety practices. In addition to the safety messages contained in this manual, safety message decals are affixed to the mower 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 2.3 Tractor Horsepower The horsepower required to operate the mower depends on several operating factors including the vegetation to be cut, terrain condition, operator experience, condition of the mower and tractor, and other factors. The recommended tractor HP for the TWR-180 is 85 HP, minimum 65 HP. The recommended tractor HP for the TWR-120 is 75 HP, minimum 50 HP.
OPERATION 2.7 Power Take Off (PTO) Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM will have a 1-3/8” diameter 6-spline shaft and those operating at 1000 RPM will have a 13/8” 21-spline shaft or a 1-3/4” 20 spline shaft.
OPERATION 3. GETTING ON AND OFF THE TRACTOR Before getting onto the tractor, the operator must read and completely understand the mower and tractor operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete explanation. WARNING! Do not mount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped. (SG-12) 3.
OPERATION 4. STARTING THE TRACTOR The operator must have a complete understanding of the placement, function, and operational use of all tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized dealer for tractor operation instructions if needed.
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 on blocks. Place a block in front of and behind the center section wheels to prevent the mower from moving. Keep hands and feet out from under the mower and clear of pinch points between the tractor and mower.
OPERATION 5.2 Connecting Mower Hydraulic Lines to the Tractor With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the control levers back and forth several times or placing the levers in the float position. Keep mower hydraulic lines, hoses, quick couplers, and swivels free of contamination. Never leave a disconnected hose end open and cap the tractor hydraulic outlet ports when not in use.
OPERATION 6.1 SETTING CUTTING HEIGHT The cut height for the center section is set by extending or shortening the depth collar located on the center lift cylinder. Cutting height for the wing cylinders will be automatically controlled by the hydraulic phasing system. Depth stops are also provided on the wing cylinders as back up for fine adjustments. IMPORTANT: If depth control stops are not set at the same height as the center cylinder, internal damage may occur to the phasing cylinders.
OPERATION 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, twist driveline yoke collar 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.
OPERATION “Bottoming Out” Check Procedure 1. Disconnect driveline from the tractor and slide the profiles together until fully compressed. 2. Place a mark on the inner shield 1/8” from the end of the outer shield and reattach the driveline to the PTO shaft. 3. With the PTO NOT TURNING, slowly drive the tractor with mower attached through the sharpest turn possible and watch shaft movement.
OPERATION 7.2 Constant Velocity (CV) Driveline For mowers 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 70°. Angles greater than 80° can 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 mower 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 mower and tractor 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 8.1 Tractor Pre-Operation Inspection/Service OPERATION Refer to the tractor operator’s manual to ensure a complete pre-operation inspection and scheduled service is performed according to manufacturer recommendations.
OPERATION ¾ ¾ Ensure that the Manual Canister is secured to the mower with the Operator’s Manual inside. Ensure all decals are in place and legible. Replace missing, worn, and unlegible decals. NOTE: The mower Operator’s Manual and affixed Decals contain important instructions on the safe and proper use of the mower. Maintain these important safety features on the mower in good condition to ensure the information is available to the operator at all times.
OPERATION ¾ ¾ ¾ ¾ OPERATION ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ Perform scheduled lubrication as specified in the maintenance section. Inspect each gearbox oil level and replenish if needed. A low oil level is a warning sign that the gearbox may be cracked or its seal is damaged and needs to be replaced. Ensure all gearbox vents are in place and free from clogs. Ensure each hydraulic cylinder is installed and retained correctly.
OPERATION DANGER Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge at the lower bend more than a 1/2" DEEP (due to running in gravel and/or the ground), REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY.
OPERATION DANGER! This Implement is wider than the Tractor. Be careful when operating or transporting this equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete abutments or other solid objects. Such an impact could cause the Implement and Tractor to pivot violently resulting in loss of steering control, serious injury, or even death. Never allow the Implement to contact obstacles. (S3PT-12) 9.
OPERATION 9.3 Operating the Mower Wings Wings are positioned with hydraulic cylinders. Ensure the hydraulic cylinders and lines are filled with oil by holding the valve control levers in the raised position until the cylinders fully retract (wings) and extend (center). Only operate the mower with both wings fully lowered, NEVER operate the mower with a raised wing. Wait until the blades are at a complete stop before raising wings.
OPERATION 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 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 10. OPERATING THE TRACTOR AND MOWER THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand the Safety and Operation Sections of the mower and tractor operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the mower and tractor without complete operating instructions.
OPERATION 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.
OPERATION 10.3 Engaging the Power Take Off (PTO) Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The mower wings must be completely lowered and the deck positioned at a safe mowing height. NEVER engage the PTO with the mower wings 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.
OPERATION 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 2” 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.
OPERATION DANGER! Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least 100 yards 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 this type of item discontinue mowing.
OPERATION When mowing across uneven areas such as road shoulders, ditch edges, and other uneven terrain, position mower so that one support wheel is near the highest point to prevent blades from cutting into gravel or dirt which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting in rapid wear or damage to these components. Blades contacting the ground may cause objects to be thrown out from under the mower deck.
OPERATION 11. DISCONNECTING THE MOWER FROM THE TRACTOR DANGER! WARNING! Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches. (S3PT-15) Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift the Tongue without using the Tongue Jack could cause strains or other injury.
OPERATION 12. MOWER STORAGE It is recommended that the mower be stored with the center section and both wings fully lowered to ground level. If the mower is stored with the wings in the raised position, select a level area and install wing transport lock pins to prevent the wings from falling BEFORE disconnecting the mower hitch and hydraulic hoses from the tractor. Store the mower with the center section transport lock pin installed or with the mower fully lowered.
OPERATION 13. TRANSPORTING THE TRACTOR AND MOWER Inherent dangers of operating the tractor and mower and the possibility of accidents are not left behind when you finish mowing an area. Therefore, the operator must employ good judgement and safe operation practices when transporting the tractor and mower between locations. By using good judgement and following safe transport procedures, the possibility of accidents while moving between locations can be substantially minimized.
OPERATION 13.1 Transporting on Public Roadways WARNING! DANGER! WARNING! Only tow the Implement behind a properly sized and equipped Tractor which exceeds the weight of the Implement by at least 20%. DO NOT tow the Implement behind a truck or other type of vehicle. Never tow the Implement and another Implement connected in tandem. Never tow the Implement at speeds over 20 MPH. (STI-6) Never allow children or other persons to ride on the Tractor or Implement.
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 mower on a public roadway. Replace the SMV emblem if faded, damaged, or no longer reflective.
OPERATION 13.2 Hauling the Tractor and Mower Before transporting a loaded tractor and mower, 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. Arrange the chains so that when tightened, the chains are pulling downward and against themselves.
