OPERATION SECTION Operation Section 4-1 © 2013 Alamo Group Inc.
OPERATION BUSH HOG BH20 SERIES ROTARY MOWER OPERATION INSTRUCTIONS OPERATION Bush Hog rotary mowers are manufactured with quality material by skilled workers. These mowers are designed to cut grass, weeds, small brush and other vegetative material up to 3” diameter in areas such as pastures, industrial areas, and roadsides. The mower is equipped with protective deflectors and/or chain guards to prevent objects being thrown from the mower by the blades, however, no shielding is 100% effective.
OPERATION 1. OPERATOR REQUIREMENTS Safe operation of the unit is the responsibility of a qualified operator. A qualified operator has read and understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor operation and all associated safety practices. In addition to the safety messages contained in this manual, safety signs are affixed to the implement and tractor.
OPERATION 2. TRACTOR REQUIREMENTS The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take Off (PTO) at the mower’s rated speed while traveling at a ground speed between 2 and 5 MPH. Operating the mower with a tractor that does not meet the following requirements may cause tractor or mower damage and be a potential danger to the operator and passersby.
2.4 3-Point Hitch The tractor 3-point hitch must be rated to lift at least, 1025 lbs (BH25), 1160 lbs (BH26), and 1540 lbs (BH27). These models are designed to be mounted on a tractor CAT I or CAT II (BH25 & BH26) CAT II or CAT III (BH27) 3-Point or Quick 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, CAT II or CAT III dimensions, the mower may not fit or raise properly.
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.
OPERATION Never allow children to operate, ride on, or come close to the Tractor or Implement. Usually, 16-17 year-old children who are mature and responsible can operate the implement with adult supervision, if they have read and understand the Operator’s Manuals, been trained in proper operation of the tractor and Implement, and are physically large enough to reach and operate the controls easily. (SG-11) 3.
OPERATION 4. STARTING THE TRACTOR OPERATION 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. Essential Tractor Controls: • Locate the light control switch. • Locate the engine shut off control. • Locate the brake pedals and the clutch. • Locate the PTO control.
OPERATION 5.1 Connecting the Mower-Lift Type 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.
OPERATION 5.2 3-Point Quick Hitch OPERATION Our 3-Point Quick Hitch is designed to connect to a Quick-Attach Coupler making mounting and dismounting your mower easier. The 3-Point Quick Hitch is also designed to connect the cutter to a tractor’s three-point linkage without the use of a Quick-Attach Coupler. 5.3 Connecting Mower - Lift Type (Quick Hitch) Crushing Hazard between Quick-Hitch and Implement. Do not allow anyone to stand between the Quick-Hitch and implement during hook-up operations.
OPERATION 5.4 Safety Tow Chain If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the gross weight of the mower must be connected between the tractor and mower. This will help control the implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached to a secure location on the tractor and not to an intermediate support.
OPERATION 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.
OPERATION BH20 Series 04/13 © 2013 Alamo Group Inc. Operation Section 4-13 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.
OPERATION 6.2 Setting Deck Pitch OPERATION 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.
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.
OPERATION 6. Hold driveline sections parallel to each other and check for minimum 6” overlap. If driveline has been marked for cutting, overlap will be the distance between two marks. if driveline has less than minimum overlap, do not use. Contact authorized Bush Hog dealer. OPERATION NOTE: If driveline is the correct length, omit the following steps 8 - 11 and proceed to step 12. 7. Clamp driveline in a well padded vice to prevent damage to the shield. Cut off shield where marked. 8.
OPERATION 10. Deburr ends of driveline sections and clean away all chips and filings. 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.
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 implement and tractor must be performed. This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing parts as soon as noticed.
OPERATION 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 the manufacturers recommendations.

OPS-R-0039_H 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.
OPERATION • • Inspect blades and blade bolts for looseness and excessive wear. Make sure the mower is securely blocked up before crawling beneath. Replace damaged, worn and missing blades as complete sets to maintain rotary balance during operation. Ensure blade pan nut is tightened with the cotter pin inserted and spread. OPS-R-0041 Inspect blade pan and blade assembly for the following: OPS-U-0031 BH20 Series 04/13 © 2013 Alamo Group Inc. Operation Section 4-23 OPERATION 8.
OPERATION OPERATION Operating the mower with loose blade hardware will damage the blade holder or blades and can result in blade breakage or blade fastener failure. Broken blades or bolts can be thrown out from under the mower for distances up to 300 feet. When the blades are replaced, the fastening hardware must be replaced. Check and retighten the blade hardware after the first eight hours of operation. In severe cutting conditions, recheck the blade carrier and blade bolt torque every 50 hours.
OPERATION 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 present, or Gouges or chipped areas in the cutting edge are larger than 1/2”(12.7mm), or The material on the leading edge has been worn away by more than 1/2(12.7mm)” BH20 Series 04/13 © 2013 Alamo Group Inc.

OPERATION Rotary Mower PRE-OPERATION Inspection Mower ID#________________ Date: ________________ IMPORTANT: Scan this QR Code for an electronic copy of this inspection sheet. www.algqr.com/rmi Condition at Start of Shift Item Specific Comments if not O.K.
OPERATION Tractor PRE-OPERATION Inspection Tractor ID#:________________________Make:________________________ OPERATION Date:______________________________Shift:________________________ 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 implement is resting on the ground or securely blocked up and all hydraulic pressure has been relieved.
OPERATION 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.
OPERATION 8.5 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 8.6 Brake and Differential Lock Setting Make sure the tractor brakes are in good operating condition.
OPERATION 8.7 Raising the Mower 8.8 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 8.9 Crossing Ditches and Steep Inclines When crossing ditches with steep banks or going up sharp inclines, it is possible that the main driveline inner profile will penetrate into the outer housing to its maximum depth until the assembly becomes solid (driveline is at its extreme shortest length).
OPERATION Inclines and ditches should be approached along a line which is at an angle as shown. This type of path will reduce the possibility of over-collapse of the driveline and resulting damage. If the gradient is so steep that such an approach increases the possibility of a tractor roll-over, select an alternate crossing path. 9. OPERATING THE TRACTOR AND IMPLEMENT THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE.
OPERATION Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. Inspect the cutting area for such objects before mowing. Remove any like object from the site. Never allow the cutting blades to contact such items. (SGM-06) OPERATION 9.
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.
OPERATION 9.4 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 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.
OPERATION OPERATION Do not let the Blades turn when the Mower Deck is raised for any reason, including clearance or for turning. Raising the Mower deck exposes the Cutting Blades which creates a potentially serious hazard and could cause serious injury or even death from objects thrown from the Blades. (SRM-07) Large, dense, or wet vegetation may need to be mowed in two or more passes to achieve a uniform cut. In such conditions, raise the cutting height to 12” or more on the first pass.
OPERATION Do not mow, or drive the tractor into material that is burning, or areas that recently burnt and may contain hot spots. Burning material, sparks, and coals could be thrown from the mower to areas of vegetation that might ignite. Tire damage can occur when driving over hot material. Oil and grease on the tractor and mower could ignite resulting in equipment destruction. Carry a fire extinguisher on the tractor at all times to extinguish possible fires encountered. 9.
OPERATION 9.7 Shutting Down the Implement OPERATION To shut down attached mower head, first bring the tractor to a complete stop. Decrease engine RPM to idle then disengage cutterhead. The mower head will come to a complete stop within a suitable amount of time. Do not engage or disengage the cutterheads at a high RPM unless there is an emergency situation.
OPERATION Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches. (S3PT-15) To disconnect the mower first extend the tractor 3point 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. After disconnecting the 3 lift points, remove the mower driveline from the tractor PTO shaft.
OPERATION 11. 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 12.1 Tire and Wheels Laminated Sectional Tires are designed for conditions where puncture proof performance is required and the mower will not be transported for long distances on roadways.
OPERATION 12.2 Transporting on Public Roadways OPERATION 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.
OPERATION 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. OPSU- 0022_A 12.
