OPERATION 2. OPERATOR REQUIREMENTS OPERATION Safe operation of the unit is the responsibility of a qualified operator. A qualified operator has read and understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor operation and all associated safety practices. In addition to the safety messages contained in this manual, safety signs are affixed to the implement and tractor.
OPERATION 3. TRACTOR REQUIREMENTS The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take Off (PTO) at the mower’s rated speed while traveling at a ground speed between 2 and 5 MPH. Operating the mower with a tractor that does not meet the following requirements may cause tractor or mower damage and be a potential danger to the operator and passersby.
OPERATION 3.3 Tractor Horsepower The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the CY84 mower requires a tractor with at least 60 HP for a lift unit and 30 HP for a pull-type. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 90 HP may cause mower damage by overpowering the unit in heavy cutting conditions. 3.
OPERATION 3.5 Drawbar - Pull-Type Mower For pull-type mowers (540 and 1000 RPM) equipped with an equal-angle driveline, the tractor drawbar must be positioned at a 14” distance from the hitch point to the PTO shaft end for proper operation and minimal wear to the driveline and tractor. 3.6 Front End Weight A minimum of 20% total tractor weight must be maintained on the tractor front end at all times.
OPERATION 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.
OPERATION Never allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death. (SG-10) 4.2 Dismounting the Tractor Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud, ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support and never rush or jump off the tractor.
OPERATION 5. STARTING THE TRACTOR The operator must have a complete understanding of the placement, function, and operational use of all tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized dealer for tractor operation instructions if needed. OPERATION Essential Tractor Controls: • Locate the light control lever. • Locate the engine shut off control. • Locate the brake pedals and the clutch. • Locate the PTO control.
OPERATION Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches. (S3PT-15) 6.1 Connecting the Mower - Lift-Type 1. Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed. 3. Board the tractor and start the engine. Position the tractor to the mower with the 3-point lift arms positioned between the respective set of mower A-frame lift lugs.
OPERATION OPERATION 6.2 Connecting the Mower - Pull-Type 1. Make sure the tractor is equipped with the correct PTO shaft and the drawbar is extended 14” from the end of the PTO shaft to the hitch point. 2. Block the mower wheels in place and use the attached parking jack to raise or lower the tongue clevis to the height of the tractor drawbar. The parking jack can be rotated 15 degrees in each direction to obtain a near vertical position.
OPERATION Safety Chains When towing implements on a public roadway, use a safety chain with tensile strength equal to or greater than the gross weight of the unit being towed. This will control the implement in the event the hitch pin is lost during transport. After the ends of the safety chain are attached to the implement and the tractor, make a trial run by driving the tractor to the right and to the left to check for proper length.
OPERATION OPERATION 8. Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2½" before the tail wheel leaves the ground. This will allow the mower to follow the contour of uneven terrain. NOTE: Install optional check chains when there is a problem with the hydraulic 3-Point lift maintaining a set height or when a constant pre-adjusted cut height is required. See Check Chains in the Assembly Section for this accessory. 7.
OPERATION 7.3 Setting Deck Pitch To facilitate safe and efficient operation, the mower should be operated with the deck approximately 3/4” LOWER IN THE FRONT THAN THE REAR. Adjust the leveling rods linking the tongue to the rear axle until the front of the mower is at least 3/4” lower in the front that than the rear. To lower the front, lengthen the leveling rods and to raise the front shorten the leveling rods. IMPORTANT: Adjust the leveling rods the same amount and maintain equal tension in the rods.
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. A driveline not attached correctly to the Tractor PTO shaft could come loose and result in personal injury and damage to the Implement. (S3PT-17) OPERATION 8.
OPERATION Engagement Check Procedure • • • • • With the driveline attached, position the mower to the point where the telescoping driveline is at its maximum extension. Turn off the tractor and securely block the mower at this position. Mark the inner driveline shield 1/8” from the end of the outer shield. Disconnect the driveline from the tractor and separate the two driveline halves. Measure the distance from the mark to the end of the inner profile.
OPERATION 9.1 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 the manufacturers recommendations.
OPERATION • Ensure deflectors and/or chainguards are in position and not damaged. Replace worn, broken, and missing pieces. OPS-R-0038 • • • Lift-Type - Ensure the tailwheel beam position support bolts are properly intalled and tightened. Pull-Type - Ensure that the tailwheel ratchet or hydraulic cylinder is installed and retained correctly to provide the desired cutting height. Inspect all bolts and screws and tighten to the recommended torque. OPS-R-0045 CY84 03/08 © 2008 Alamo Group Inc.
OPERATION • • OPERATION • • • • • Ensure the tractor PTO master shield and the mower slip clutch shield are in place, lowered, and in good condition. Ensure the driveline integral shield is in good condition and rotates freely. Ensure the driveline slip clutch (if equipped) is properly adjusted. OPS-R-0039 Inspect the gearbox oil level. A low oil level is a warning sign that the gearbox may be cracked or its seal is damaged and needs replacement.
OPERATION 9.3 Cutting Component Inspection Inspect blade pan and blade assembly for the following: OPS-U-0031 OPERATION Inspect the Blades daily for abnormal wear. REPLACE BOTH BLADES on that carrier IMMEDIATELY if either blade has: • • • • • Become bent or deformed from it’s original shape or Any cracks are visible, or Deep gouges in the blade’s surface are persent, or Gouges or chipped areas in the cutting edge are larger than 1/2”(12.
OPERATION 9.4 Blade Bolt Inspection OPERATION Inspect Blade Bolt Head daily for wear as followed: Inspect the Blade Bolt Heads daily for abnormal wear. REPLACE BOTH BLADE BOLTS on the Blades IMMEDIATELY if either blade bolts has: • Visible cracks or • If the blade bolt crown 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.

OPERATION Rotary Mower PRE-OPERATION Inspection Mower ID#________________ Make ____________________ Date: Shift ________________ ____________________ OPERATION Before conducting the inspection, make sure the tractor engine is off, all rotation has stopped and the tractor is in park with the parking brake engaged. Make sure the mower is resting on the ground or securely blocked up and all hydraulic pressure has been relieved. Condition at Start of Shift Item Specific Comments if not O.K.
OPERATION 10. DRIVING THE TRACTOR AND IMPLEMENT Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with an attached implement, review the following.
OPERATION 10.1 Starting the Tractor OPERATION The procedure to start the tractor is model specific. Refer to the tractor operator’s manual for starting procedures for your particular tractor. Consult an authorized dealer if the starting procedure is unclear. Ensure the 3-point control lever is in the lowered position and the PTO is disengaged before starting the tractor. OPS-U-0033 10.2 Brake and Differential Lock Setting Make sure the tractor brakes are in good operating condition.
OPERATION 10.3 Raising the Mower 10.4 Driving the Tractor and Mower Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent the operator from stopping quickly during an emergency.
OPERATION OPERATION Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills only at a low speed and using a gradual steering angle. Rear mounted implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over.
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. 11. OPERATING THE TRACTOR AND IMPLEMENT THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE.
OPERATION Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. Inspect the cutting area for such objects before mowing. Remove any like object from the site. Never allow the cutting blades to contact such items. (SGM-6) OPERATION 11.
OPERATION Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.
OPERATION 11.4 PTO RPM and Ground Speed OPERATION Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground speed.
OPERATION Do not mow with two machines in the same area except with Cab tractors with the windows closed. (SGM-11) Avoid mowing in reverse direction when possible. Check to make sure there are no persons behind the mower and use extreme care when mowing in reverse. Mow only at a slow ground speed where you can safely operate and control the tractor and mower. Never mow an area that you have not inspected and removed debris or foreign material.
OPERATION OPERATION When you get to the end of a pass, slightly raise the mower (2-4”) before turning. Never raise the mower entirely while the blades are turning. If the mower must be raised higher than 12” from ground level, disengage the tractor PTO and wait for all mower rotation to come to a complete stop before proceeding to raise the mower. When turning, the angle between the tractor and mower should not be so great that a clattering of the U-joints occurs.
OPERATION Then lower the mower to the desired height and mow the vegetation a second time. If possible, select a mowing pattern that is at a 90 degree angle to the first pass to reduce streaking for a more uniform cut. OPS-R-0044 CY84 03/08 © 2008 Alamo Group Inc. Operation Section 4-35 OPERATION Stay alert and watch for trees, low hanging limbs, power lines, and other overhead obstacles and solid ground objects while you are operating. Use care to avoid hitting these items.
OPERATION 11.6 Shutting Down the Implement OPERATION To shut down the implement, first bring the tractor to a complete stop. Then slow down the implement by reducing the engine speed before disengaging the PTO. Wait for all motion to stop before proceeding to drive or shut down the tractor.
OPERATION Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches. (S3PT-15) Lift-Type Mower - To disconnect the mower, first extend the tractor 3-point hitch top link to remove tension on the top link hitch pin. When the pin is loose and easy to rotate, remove the pin from the mower. Next remove both lower hitch pins.
OPERATION 13. MOWER STORAGE Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service. The following are suggested storage procedures: • OPERATION • • • • • • Thoroughly clean all debris off the mower to prevent damage from rotting grass and standing water. Lubricate all mower grease points and fill gearbox oil levels as detailed in the maintenance section.
OPERATION If the tractor’s hydraulic pump is not independent of the tractor PTO, or if the tractor PTO has to be run to have hydraulic power, disconnect the mower driveline from the tractor PTO output shaft. Secure the driveline to the mower deck to prevent driveline damage or loss during transport. OPS-R-0034 14.1 Transporting on Public Roadways Extreme caution should be used when transporting the tractor and implement on public roadways.
OPERATION OPERATION The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day and night visibility. Make sure the SMV sign is clean and visible from the rear of the unit before transporting the tractor and implement on a public roadway. Replace the SMV emblem if faded, damaged, or no longer reflective.
OPERATION Reduce speed before turning or applying the brakes. Ensure that both brake pedals are locked together when operating on public roads. OPS-U- 0023 Before transporting a loaded tractor and implement, measure the height and width dimensions and gross weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the areas that will be traveled through.
OPERATION OPERATION 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.

MAINTENANCE SECTION Maintenance Section 5-1 © 2008 Alamo Group Inc.
MAINTENANCE Before operating your Rotary Cutter, make sure it is properly lubricated and thoroughly inspected. Only a minimum of time and effort is required to regularly lubricate and maintain this machine to provide long life and trouble free operation. MAINTENANCE Always disengage the PTO before raising the Rotary Cutter for transporting or making adjustments. Lubrication Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
MAINTENANCE Gearbox Lubrication The Gearbox has been filled with lubricant to the Test Plug Level prior to shipment. However, you should check the oil level at Test Plug before operating, and frequently thereafter. NOTE: Overfilling the Gearbox will cause pressure to build up and cause Oil Seals to leak. ATTENTION: If the Gearbox suddenly starts making an unusual noise, stop at once, check for leaks, and refill Gearbox as required.
MAINTENANCE Driveline Lubrication MAINTENANCE 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. Do not force grease through the Needle Cup Assemblies. Grease the telescoping tubes after every 8 hours use. Some PTO-to-Hitch connections may necessitate cutting a hole in the shields to be able to align the Grease Fitting holes for lubrication. Lubricate the shield bearings every 16 hours (Figure Mnt-0012).
MAINTENANCE Protective, Integral Shields - Lift-Type Driveline Integral Shields must be in place at all times when operating. CY84 03/08 © 2008 Alamo Group Inc. Maintenance Section 5-5 MAINTENANCE Protective Driveline Shields should be installed on Drivelines as shown in Figure Mnt-0013 below. The protective Integral Shields are assembled onto nylon bearings and should turn freely - but should not spin. Greasing the nylon bearings is not required but will not harm them.
MAINTENANCE Slip Clutch Avoid overheating of the Slip Clutch by too long or too frequent slipping, as this can damage the friction plates and limiter parts. When checking Slip Clutch for overheating, DO NOT touch with hand. Slip Clutch could be extremely hot and cause severe burn. MAINTENANCE If an adjustment is required, this may be done in the field by following the procedure outlined below. Following these instructions will give maximum rated torque and long life (Figure Mnt-0006). 1.
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.
MAINTENANCE Blade Removal MAINTENANCE To remove blades for sharpening or replacement, remove the cover plate on deck of cutter near gear box. Remove lock nut from blade bolt. NOTE: Inspect lock nut after removal and replace if threads are damaged. Always replace 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.
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. Thoroughly clean the cutter. 3. Tighten all bolts and pins to the recommended torque. 4. Check the cutter for worn or damaged parts.
