SAFETY WARNING! The operator and all support personnel should wear hard hats, safety shoes, safety glasses, and proper hearing protection at all times for protection from injury including injury from items thrown by the equipment. (SG-16) SAFETY CAUTION! 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.
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.

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 others. For most mowing conditions, the SR14 and SR20 mower requires a tractor with a minimum of 75 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
OPERATION 2.6 Front End Weight A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership. 2.
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 DANGER! BEFORE leaving the Tractor seat, always engage the brake and/or set the Tractor transmission in parking gear, disengage the PTO, stop the engine, remove the key, and wait for all moving parts to stop. Place the Tractor shift lever into a low range or parking gear to prevent the Tractor from rolling. Never dismount a Tractor while it is moving or while the engine is running. Operate the Tractor controls from the Tractor seat only. (SG-9) Use hand rails and steps when exiting the tractor.
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. When connecting the mower hydraulic lines, keep 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. 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.
OPERATION LEVELING WING SECTIONS WITH CENTER 1. To level the wing sections with the deck center, adjust the leveling screw between the wing axle and the center axle. To lower the wing, loosen the jamnut and shorten the screw assembly, lengthen the screw assembly to raise the wing. After wings are leveled, retighten jamnuts to maintain settings. 6.
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, 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.
OPERATION 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 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 ¾ ¾ ¾ ¾ ¾ ¾ ¾ Inspect blades and blade bolts for looseness and excessive wear. Make sure the mower is securely blocked up before crawling beneath. Replace damaged, worn, and missing blades as complete sets to maintain rotary balance. Ensure carrier hub nuts are tightened with the cotter pin inserted and spread. Inspect the condition of the deck skid shoes and the skid shoe attaching hardware. Ensure each hydraulic cylinder is installed and retained correctly.
OPERATION 9. DRIVING THE TRACTOR AND MOWER 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 mower and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with an attached mower, review the following. DANGER! OPERATION WARNING! This Implement is wider than the Tractor.
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. 9.2 Brake and Differential Lock Setting WARNING! Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
OPERATION 9.3 Operating the Mower Wings Wings are positioned with hydraulic cylinders. It is recommended that the tractor be equipped with three hydraulic ports or a 3-spool control valve be used so that each section can be controlled independently. 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).
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 2-1/2” 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 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. NEVER raise the mower wings while the blades are turning.
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 10.6 Shutting Down the Mower To shut down the mower, first bring the tractor to a complete stop. Then slow down the mower by reducing the engine speed before disengaging the PTO. Wait for all rotating motion to stop before proceeding to drive or shut down the tractor.
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 braces to prevent the wings from falling BEFORE disconnecting the mower hitch from the tractor. Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service.
OPERATION 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 Before transporting the tractor on a public roadway or boarding a trailer for transport, the tractor brake pedals should be locked together. Locking the pedals ensures that both wheels brake simultaneously while stopping, especially when making an emergency stop. Use extreme caution and avoid hard applications of the tractor brakes when towing heavy loads at road speeds. Never tow the mower at speeds greater than 20 MPH.
OPERATION 13.1 Transporting on Public Roadways WARNING! DANGER! OPERATION 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 Make sure that all tractor flashing warning lights, headlights, and brake/taillights 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 where only equipped with operating lights. Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models. Reduce speed before turning or applying the brakes.
OPERATION 13.2 Hauling the Tractor and Mower OPERATION 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. Use adequately sized and rated trailers and equipment to transport the tractor and mower. Consult an authorized dealer to determine the proper equipment required.

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. WARNING 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 be dangerous. DANGER! Replace bent or broken blade with new blades.
MAINTENANCE BLADE SHARPENING Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in FIGURE 22. Always sharpen blades by grinding. 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. IMPORTANT: When sharpening blades, grind each blade the same amount to maintain balance. The difference in blade weights should not exceed 1 ounce.
MAINTENANCE BLADE CARRIER REMOVAL Remove cotter pin and loosen slotted nut on gear box shaft. Loosen but do not remove the nut until the blade carrier is loosened. Use a suitable two-jaw gear puller to pull carrier off tapered gear box 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.
MAINTENANCE SEASONAL CLUTCH MAINTENANCE It is important that the clutches 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/frozen together. Before using the cutter use the following procedure to make sure the clutch will slip and give the overload protection required. 1. 2. 3. 4.
MAINTENANCE 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. 2. 3. 4. 5. 6. Thoroughly clean the cutter. Lubricate the cutter as covered in Maintenance Section.

MAINTENANCE DISASSEMBLY OF DIVIDER GEARBOX (Trained dealer personnel only) STEP 1 Place the Divider Gearbox on a flat surface. Drive a sharp object through the Seal and force it out of the Hub Cap. FIGURE 25. FIGURE 25 FIGURE 26 FIGURE 27 SR20M/SR14M 06/98 © 2004 Alamo Group Inc. Maintenance Section 5-15 MAINTENANCE STEP 2 Remove all eight of the M10 Bolts from both Cap Hubs, using a 14mm socket. FIGURE 26. Remove the Hub Assemblies and gaskets from the Main Housing. FIGURE 27.
MAINTENANCE STEP 3 Remove the Hub Assembly from the vise and place it on a solid surface with the Gear in an upright position. Using a Hammer, tap this Gear downward until the Adjusting Nuts fully exposed. Remove the Cotter Pin. Remove the Adjusting Nut. FIGURE 28. MAINTENANCE FIGURE 28 STEP 4 Laying the Hub Assembly on its side, tap the Gear end of the Output Shaft into the Gear and Bearing. Once the Shaft has cleared the Bearing, it can be fully removed from the Hub Assembly.
MAINTENANCE STEP 5 Remove all eight Bolts from Input Cap using a 14mm Socket. Then using a Hammer, tap the Output end of the Input Shaft. This will loosen the input Cap and allow the removal of the complete Input Shaft Assembly. FIGURE 30. FIGURE 30 STEP 6 The Input Gear and Bearing can be removed from the Input Shaft by tapping the end of the Input Shaft on a solid surface. FIGURE 31.
MAINTENANCE Assembly of WW75-340 STEP 1 Install the Bearing Race into the Hub cap. STEP 2 Install the Bearing on the Output Shaft. FIGURE 33. Place the Shaft into the Hub Cap. FIGURE 34. Place the Bearing FIGURE 35on the Shaft and carefully drive it down FIGURE 36. Replace any shims found in disassembly, Place the Gear FIGURE 37on the Shaft so that the threads, for the Adjusting Nut, on Shaft are exposed. FIGURE 34 FIGURE 35 MAINTENANCE FIGURE 33 FIGURE 36 SR20M/SR14M 04/94 © 2004 Alamo Group Inc.
MAINTENANCE STEP 3 Apply some Locktite on the Adjusting Nut FIGURE 38. Install the Adjusting Nut onto the Shaft FIGURE 39. Tighten the Nut until it is difficult to turn the Shaft FIGURE 40. While holding Hub, tap each end of the Shaft and check to see if it has loosened. Repeat this process until the Shaft no longer becomes loose in the assembly. Unscrew the Nut a small amount and again tap each end of Shaft while holding the Hub.
MAINTENANCE STEP 4 Apply a small amount of Silicon sealer to the bore of the Hub Cap and to the outside diameter of the Seal . FIGURE 42. Drive the Seal into the base of the Hub Cap. FIGURE 43-46. Care should be taken to keep the Seal in line with the base when driving it into place. MAINTENANCE FIGURE 42 FIGURE 43 FIGURE 44 FIGURE 46 SR20M/SR14M 04/94 © 2004 Alamo Group Inc.
MAINTENANCE STEP 5 Install the Bearing Race into the Main Gear Box Housing. STEP 6 Install Bearing on the Shaft. On the opposite end of the Shaft, install one .012" and one .020" Gear Adjusting Shims. Install the Gear Spacer and the Gear. Install one .020" thick Gear Adjusting Shim and install the Bearing. FIGURE 47& 48.
MAINTENANCE STEP 8 Install a total thickness of .020" of Shims onto Hub Cap. Mount the Hub Caps on the Housing and install four Bolts, placing them in every other bolt hole, and tighten. Check the rotation of the Gear mesh. The Gear set should turn smoothly with little noise. The maximum backlash of Gear Mesh should not exceed .022 inches. By adding Shims to Hub Cap the backlash may be increased, or it may be reduced by removing Shims .
MAINTENANCE STEP 11 Install the second Spindle Hub assembly on the Main Housing. Check the amount of backlash present between its Gear and the Gear on the Input Shaft. The amount of backlash between these two Gears needs to be set to the same amount that was set on the first Gear mesh. Add or subtract Shims as required. Once this adjustment is made, remove the Hub Cap and apply sealer as before, then reinstall on Housing. Install all eight bolts and tighten to a torque of 31 to 34 foot pounds.
