and rough terrain.
Make sure you are in compliance with all local and state regulations regarding transporting
equipment on public roads and highways. Lights and slow moving signs must be clean and
visible by overtaking or oncoming traffic when equipment is transported.
SAFETY CHAIN - If equipment is going to be transported on a public highway, a safety
chain should be obtained and installed. Always follow state and local regulations regarding
a safety chain and auxiliary lighting when towing farm equipment on a public highway. Be
sure to check with local law enforcement agencies for your own particular regulations. Only
a safety chain (not an elastic or nylon/plastic tow strap) should be used to retain the
connection between the towing and towed machines in the event of separation of the
primary attaching system.
Install the safety chain by crossing the chains under the tongue and secure to the draw bar
cage or hitch or bumper frame.
Beware of bystanders, particularly children! Always look around to make sure that it is
safe to start the engine of the towing vehicle or move the unit. This is particularly important
with higher noise levels and quiet cabs, as you may not hear people shouting.

machinery on public roads.
Use approved accessory lighting flags and necessary warning devices to protect operators
of other vehicles on the highway during daylight and nighttime transport. Various safety
lights and devices are available from your dealer.
The use of flashing amber lights is acceptable in most localities. However, some localities
prohibit their use. Local laws should be checked for all highway lighting and marking
When driving the tractor and equipment on the road or highway under 20 mph at night or
during the day, use flashing amber warning lights and a slow moving vehicle (SMV)
identification emblem.
Plan your route to avoid heavy traffic.
Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including
narrow bridges, intersections, etc.
Be observant of bridge loading ratings. Do not cross bridges rated lower than the gross
weight as which you are operating.
Watch for obstructions overhead and to the side while transporting.
Always operate equipment in a position to provide maximum visibility at all times. Make
allowances for increased length and weight of the equipment when making turns, stopping
the unit, etc.
Pick the levelest possible route when transporting across fields. Avoid the edges of ditches
or gullies and steep hillsides.
Be extra careful when working on inclines.
Maneuver the tractor or towing vehicle at safe speeds.
Avoid overhead wires or other obstacles. Contact with overhead lines could cause serious
injury or death.
Avoid loose fill, rocks and holes; they can be dangerous for equipment operation or
Allow for unit length when making turns.
Operate the towing vehicle from the operator’s seat only.
Never stand alongside of unit with engine running or attempt to start engine and/or operate
machine while standing alongside of unit.
Never leave running equipment attachments unattended.
As a precaution, always recheck the hardware on equipment following every 100 hours of
operation. Correct all problems. Follow the maintenance safety procedures.
Following operation, or when unhitching, stop the tractor or towing vehicle, set the brakes,
disengage the PTO and all power drives, shut off the engine and remove the ignition keys.
Store the unit in an area away from human activity.
Do not park equipment where it will be exposed to livestock for long periods of time.
Damage and livestock injury could result.
Do not permit children to play on or around the stored unit.
Make sure all parked machines are on a hard, level surface and engage all safety devices.
Wheel chocks may be needed to prevent unit from rolling.
Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.
Proper servicing and adjustments are key to the long life of any implement. With careful
inspection and routine maintenance, costly downtime and repairs can be avoided.
Some parts and assemblies can be quite heavy. Before attempting to unfasten any part or
assembly, arrange to support it by means of a hoist, by blocking or by use of an adequate
arrangement to keep it from falling, tipping, swinging or moving in any manner which may
hurt somebody or damage the equipment.
Always use lifting equipment that is adequately rated to do the job. Never lift equipment
over people.
Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a
closed building. The exhaust fumes may cause asphyxiation.
Before working on the equipment, stop the towing vehicle, set the brakes, disengage the
PTO and all power drives, shut off the engine and remove the ignition keys.
Be certain all moving parts on attachments have come to a complete stop before attempting
to perform maintenance.
Always use a safety support and block the wheels. Never use a jack to support the
Always use the proper tools or equipment for the job at hand.
Use extreme caution when making adjustments.
Never replace hex bolts with less than grade five bolts unless otherwise specified.
After servicing, be sure all tools, parts and service equipment are removed.
Where replacement parts are necessary for periodic maintenance and servicing, genuine
factory replacement parts must be used to restore your equipment to original specifications.
The manufacturer will not claim responsibility for use of unapproved parts and/or
accessories and other damages as a result of their use.
If equipment has been altered in any way from original design, the manufacturer does not
accept any liability for injury or warranty.
If repairs require the use of a torch or electric welder, be sure that all flammable and
combustible materials are removed.
Do not weld or cut on any tank containing oil, fuel or their fumes or other flammable
material, or any container whose previous contents are unknown.
Cleaning solvents should be used with care. Petroleum based solvents are flammable and
present a fire hazard. Don’t use gasoline. All solvents must be used with adequate
ventilation and their vapors should not be inhaled.
Only adequately trained and qualified persons should work on hydraulics systems. You may be
severely injured or killed by being crushed under a falling piece of equipment. Always have
transport locks in place and frame sufficiently blocked when working on any implement.
Hydraulic fluid escaping under pressure can have sufficient force to cause injury. Keep all
hoses and connections in good serviceable condition. Failure to heed may result in serious
personal injury or death. Escaping hydraulic fluid under pressure can have sufficient pressure
to penetrate the skin causing serious injury. Avoid the hazard by relieving the pressure before
disconnecting lines or performing work on the system.
Make sure hydraulic fluid connections are tight and all hydraulic hoses and lines are in good
condition before applying pressure to the system. Use a piece of paper or cardboard, NOT
BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or
goggles when working with hydraulic systems. DO NOT DELAY! If an accident occurs, see a
doctor familiar with this type of injury immediately. Any fluid injected into the skin or eyes must
be treated within a few hours or gangrene may result.
Always secure equipment with solid supports before working on or under it. Never work under
equipment supported by hydraulics. Hydraulics can drop equipment if controls are actuated or
hydraulic lines burst or pressure is lost while disconnecting lines. Either situation can drop
machinery instantly even when power to hydraulics is off. Do not attempt to disconnect a
hydraulic cylinder or hose while the system is under pressure!
Check hydraulic hoses and fittings frequently. Brush and other debris can damage hoses and
fittings. Inspect and maintain equipment daily. Loose, broken, and missing hardware can
cause equipment to not perform properly and can result in bodily injury or death.
Hydraulic systems and oil can be hot and cause burns. Before working on any system, wait
until the oil has cooled.
Think, plan and check. Think through the entire procedure and identify all the steps that are
required. Plan what personnel will be involved, what needs to be shut down, what guards need
to be removed, and how (and under what conditions) the power will be restarted. Check the
machine over to verify all power sources and stored energy have been identified including
engines, hydraulic and pneumatic systems, springs and accumulators, and suspended loads,
Shutoff and lockout power before adjusting, servicing, maintaining, or clearing an obstruction
from this machine. Failure to heed may result in serious injury or death. Communicate with
everyone involved in a repair or maintenance operation, including bystanders, that work is being
done which involves keeping this machine safety at a ZERO ENERGY STATE.
OSHA’s requirements for lockout/tag out are covered in Section 1910.147 of the OSHA
standards. The LOTO standard establishes the employer's responsibility to protect workers
from hazardous energy. Employers are required to train each worker to ensure that they know,
understand, and are able to follow the applicable provisions of the hazardous energy control
Proper lockout/tag out (LOTO) practices and procedures safeguard workers from the
release of hazardous energy. The OSHA standard for The Control of Hazardous Energy
(Lockout/Tag out) for general industry, outlines specific action and procedures for
addressing and controlling hazardous energy during servicing and maintenance of
machines and equipment. Employers are also required to train each worker to ensure
that they know, understand, and are able to follow the applicable provisions of the
hazardous energy control procedures. Workers must be trained in the purpose and
function of the energy control program and have the knowledge and skills required for
the safe application, usage and removal of the energy control devices.
All employees who work in the area where the energy control procedure(s) are utilized
need to be instructed in the purpose and use of the energy control procedure(s) and
about the prohibition against attempting to restart or reenergize machines or equipment
that is locked or tagged out.
All employees who are authorized to lockout machines or equipment and perform the
service and maintenance operations need to be trained in recognition of applicable
hazardous energy sources in the workplace, the type and magnitude of energy found in
the workplace, and the means and methods of isolating and/or controlling the energy.
Specific procedures and limitations relating to tagout systems where they are allowed.
Retraining of all employees to maintain proficiency or introduce new or changed control
OSHA outlines a six-step procedure for controlling hazardous energy:
Step 1: Prepare for shutdown. It must be determined what type of power system is
going to be deactivated including electrical, hydraulic, pneumatic or other energy
sources. Knowledge of shut down methods is necessary.
Step 2: Shutdown the equipment. This should be completed consistent with the
manufacturer’s instructions for the shutdown procedure and could be a simple as placing
a switch in the “off” position or pressing a button.
Step 3: Isolate the equipment. This step involves closing of valves, throwing the main
disconnects or circuit breakers and disconnecting or capping any auxiliary power
sources or secondary electrical systems.
Step 4: Apply the lockout/tag out device. This is done to prevent restoration of the
flow of energy and is done at all disconnect switches, valves or other energy isolating
devices. Locks are the preferred method of controlling energy and should be
supplemented with tags. Various lockout devices are available including group lockout
hasps. Locks should be individually assigned and have only one key.
Step 5: Control the stored energy. This step includes the release, disconnect or
restraint of any residual hazardous energy which may be present and a check that all
moving parts have stopped moving. It may also include the installation of “pancakes” or
blanking of pipe flanges, the installation of ground wires to discharge electrical
capacitors and the blocking or supporting of elevated equipment.
Step 6: Verify isolation of equipment. Double-check the steps and verify that the
equipment indeed has been shut down and that the lock and tag do control the stored
energy. Employees should be warned and the system tested, including pressing of all
start buttons to assure that the equipment will not start.
Rotary Cutter Safe Practices Messages from the
American Society of Agricultural and Biological Engineers
The following safe practices are recognized as being effective for enhancing safety, if followed,
but may not be adequate, complete, or entirely applicable for every situation. They may not
cover all possible hazardous situations; hence, they should be interpreted judiciously.
Personal protective equipment such as, but not limited to, gloves, safety glasses, hard hat,
and safety shoes should be worn when hazards to personal safety exist when operating
Lower mower, disengage PTO, stop engine, remove key, de-energize hydraulics, set
brake, and wait for all moving parts to stop before dismounting to park or service
Securely support or block up before working underneath any lifted mower or component to
avoid injury or death from inadvertent dropping due to hydraulic leak down, mechanical or
hydraulic system failure, or inadvertent operation of controls.
The tractor must be equipped with a roll-over protective structure (ROPS) except where the
use of ROPS would create an additional hazard. The operator must fasten seat belt snugly
prior to starting engine on tractors having ROPS in place. Avoid accidental fall-off or
possible injury or death from tractor or equipment run-over by using seat belt during
mowing operations.
Operate the mower from the operator’s seat only.
Do not allow riders on the mower.
Do not allow rider on the tractor unless there is a seat belt-equipped position that is ROPSprotected for each rider.
Visually check for hydraulic leaks and broken, missing, or malfunctioning parts, and make
necessary repairs. Do not use your hand to check for leaks: use cardboard or similar
material. Escaping hydraulic oil under pressure can have sufficient force to penetrate the
skin and cause a serious personal injury or death. The injected fluid may result in
gangrene if the fluid is not surgically removed immediately by a doctor familiar with this
form of injury.
Before disconnecting hydraulic lines, release all hydraulic pressure.
Keep implement input driveline, implement input connection, and tractor PTO shield in
place and in good condition when operating. Be sure the driveline is securely locked onto
the PTO.
Do not open access doors or remove guards until rotating components have stopped.
Mowers that are provided with intake and/or discharge shield that may be subject to routine
wear or deterioration must be inspected regularly and maintained as instructed by the
manufacturer in the operator’s manual.
Make certain the slow moving vehicle (SMV) sign and other reflectors are clearly visible.
Follow local traffic codes for slow moving vehicles when transporting on public roads.
Attach safety chain between towed mower and propelling machine as shown in operator’s
manual before towing on public roads.
Add enough weight to assure at least 20% of the tractors original weight is on the front
wheels for safe transport.
Tractor wheel tread spacing should be increased when working on incline or rough ground to
reduce the possibility of tipping.
Use stabilizer bars or sway blocks to prevent side sway of the cutter.
The linkage to the lower draft links should be set in the “Float Position”, allowing the unit to
Follow the contour of the terrain.
Shorten of remove drawbar so it will not interfere with the up and down movement of the cutter.
A crushing hazard exists when hooking-up equipment to a tractor. Do not allow
anyone to stand between
tractor and implement while backing-up to implement. Do not operate hydraulic 3point lift controls while someone is directly behind tractor near implement.
To mount the cutter, be sure it is sitting on as level ground as possible and follow the steps
outlined in the manual for attaching a three-point hitch implement.
1. Slowly back up to the rotary cutter while using tractor's 3-point hydraulic control to align lower
3-point arm holes with the hitch pins.
2. Engage tractor park break, shut tractor engine off, and remove key before dismounting from
the tractor.
3. Attach the cutter hitch pins to the lower three-point lift arms of the tractor.
4. Connect the tractor top link to the hole in the top of the A-Frame link or the cutter using the
pin supplied. With the rotary cutter attached to the tractor’s three-point hitch, proceed to
connection of the PTO as follows.
5. Slide the yoke with the quick disconnect pin onto the tractor PTO shaft. Move the yoke back
and forth to insure it is locked onto the shaft.
6. Attach the safety chain to the stationary point to prevent the shield from spinning.
7. Return to the tractor and slowly raise and lower the cutter to ensure that the drawbar, tires,
and other equipment on the tractor do not make contact with the cutter frame and driveline.
Move or remove drawbar if needed.
8. Adjust the lower lift arms on the tractor to level the cutter from left to right.
9. Adjust the length of the top-link to level the cutter from front to rear.
A driveline that is too long can bottom out causing damage to the tractor and cutter. Always
check the driveline collapsed length during initial setup, when connecting to a different tractor,
and when alternating between using a quick hitch and a standard 3-point hitch.
Telescoping tubes must always overlap by at least ½ of their length in normal operations and at
least 1/3 of their length in all working conditions.
Pay particularly close attention to the SAFETY MESSAGES regarding cutter transport. Avoid
unnecessary injuries and equipment damage by exercising cautious and conscientious travel
Attaching the cutter to the tractor increases the overall length of the working unit. Allow
additional clearance for the cutter to swing when turning.
Raise the cutter as high as possible for transporting while maintaining clearance between the
driveline and the deck of the cutter.
Tire pressure should be kept at around 20 PSI to decrease shock during transport. When using
puncture-proof, laminated tires, be sure that the flat side of the lug nut is against the wheel.
When transporting the cutter on a road or highway, use tractor warning lights, SMV
reflectors and other safety devices for adequate warning to the operators of other
Check the traffic regulations governing locale where mowing is to be done and work safely
within those guidelines
Be sure that the tractor lift lever is locked into the "transport" detent before attempting to
Transport the cutter. Make sure that at least 20% of the tractor weight is on the front tires.
Hold transport speed to 15 mph, especially when using puncture-proof, laminated
tires. These tires are designed for off road use only. They can be used on road
surfaces at very low speeds for a short distance. Heat from pavement friction can
build up causing the tire to ignite. The steel band holding the sections in place
could break, causing extensive damage to the cutter and tractor as well as possible injury to the
operator and passerby. When transporting up slopes with reduced front end weight the
tailwheel should be lowered as far as possible to provide a stop if the tractor rears up.
Avoid personal injury. Be sure the tractor engine is off and the key is removed
before making and adjustments.
IMPORTANT: Avoid very low cutting heights. Striking the ground with the blades
gives the most damaging shock loads a cutter can encounter and will cause
damage to the cutter and driveline.
To achieve maximum cutting efficiency and provide the most uniform cut, the cutter should be
operated with the rear
slightly higher (1/2"-3/4") than the front.
1. Place the tractor and cutter on level surface
2. Raise the cutter to the approximate desired cutting height with the tractor hydraulic lift
control lever.
3. Remove the gauge wheel adjusting bolt from the rear adjusting brackets. Adjust the
gauge wheel
leg to the desired cutting height and reinstall the bolt.
4. Lower slowly until the cutter is 1/2"-3/4" higher at the rear than the front. Position the
adjustable stop on the tractor lift quadrant against the lift control lever so that the cutter
can be returned to the same cutting height.
IMPORTANT: When raising the cutter to transport height, be sure there is clearance between
the front of the deck and driveline. Damage will result if the driveline hits the cutter deck.
Power for operating the cutter is supplied from the tractor PTO. Refer to the tractor manual for
instructions on engaging ad disengaging the PTO. Always engage the PTO at low engine RPM.
Always operate at 540 RPM. Learn how to stop the tractor and cutter quickly in case of an
IMPORTANT: Stop the cutter and the tractor immediately upon striking and obstruction. Inspect
the cutter and repair before resuming operation.
Avoid personal injury. When attempting to stop a tractor which does not have live
PTO, the momentum created by the cutter can cause the tractor to be pushed
The installation of an overrunning clutch is recommended if the operating tractor does not have
live power take off. See your dealer for additional information.
To start operation, reduce engine speed and engage the tractor PTO. Before starting to cut,
gradually increase engine speed to develop 540 RPM at the PTO.
Install chain guards if operating with people or livestock in the area or close to
highways or buildings.
Enter the area to be cut with the cutter operating at 540 RPM and, if it becomes necessary to
temporarily regulate engine speed during operations, increase or decrease throttle gradually never exceed 540 RPM.
To transport, disengage the PTO and raise the machine to full transport height.
Proper ground speed for the cutter will depend upon the height, type and density of the material
to be cut. Normally, ground speed will range from 2 to 5 mph. Tall dense material should be
cut at low speed, while medium height material can be cut at a faster ground speed.
Always operate PTO at 540 RPM when cutting. This is necessary to maintain proper blade
speed to produce clean cut. Under certain conditions, the tractor tires may roll some of the
grass down and prevent it from being cut at the same height as the surrounding area. When
this occurs, reduce the tractor ground speed, but maintain 540 PTO RPM. The lower speed will
permit the grass to partially rebound and be cut. Taking a partial cut or reversing the direction of
travel may also produce a cleaner cut.
Avoid personal injury. Pick up all rocks and other debris before cutting. Enter new
areas carefully. Drive slowly and cut material higher the first time to allow the cutter
to clear unseen objects. Never assume an area is clear. Always check for hidden
Extremely tall grass should be cut twice. Raise the cutter and cut twice the desired height. Cut
the second time at the desired height at 90 degrees to the first pass.
Remember, sharp blades produce cleaner cuts and use less power.
Before cutting, study the area to determine the best cutting procedures. Consider the height
and type of material and the terrain type: hilly, level, or rough.
Avoid tractor rollovers: Be careful when operation the tractor and cutter on uneven ground.
Equip your tractor with a roll bar (ROPS) and seat belts. Keep seat belts tightened securely.
In uneven terrain, rear wheel weights, front tractor weight and/or front tire ballast should improve
stability. Pass diagonally through sharp dips and avoid drops to prevent "hanging up" the
tractor and cutter.
Avoid sudden stops and starts while traveling up or down hills.
When cutting on slopes, always operate the cutter in a downward motion and do not travel
across the face of a slope. Avoid operation on steep slopes. Slow down on sharp turns to
prevent tipping or loss of control.
Proper servicing and adjustments are the key to the long life of any machine. With careful and
systematic inspection of the Rotary Cutter, you can avoid costly maintenance, time and repair.
WARNING: For safety reasons, each maintenance operation must be performed
with the PTO shaft disengaged, cutter lowered completely to the ground or on
safety supported blocking, the tractor engine shutoff and the ignition key removed.
1. PTO U-Joints & Profiles
2. Tailwheel spindle tube
3. Tailwheel hub
Lubricate every 50 hours of operation. On the Brave 7 the flange mounted gearbox oil reserve
is 38 ounces. If the oil reserve is below normal level, check for a crack in the gearbox or leaking
seal. The oil must be checked after every 10 hours of operation. If oil flows out of the 1/8" oil
level plug the proper lubrication level is being maintained. If oil does not flow out of the plug,
add oil until it does.
Recommended lubricant is SAE80w-90EP oil. Check the oil in the gearbox when the cutter is
level. DO NOT over fill the gearboxes. This will cause pressure to build up and cause oil seals
to leak.
Grease fittings are located on the cross of each U-Joint, Grease after each 10 hours of use.
The telescoping PTO shaft inside the shielding must be lubricated daily.
Disconnect the driveline from the tractor and pull the halves apart. Insert grease into the cavity
on the half attached to the gearbox and spread evenly. Install the driveline halves together.
Reconnect the driveline to the tractor. Raise and lower the cutter after applying grease to
spread over working joint area.
WARNING: When attaching the PTO yoke to the tractor PTO shaft, it is important
that the spring activated locking pin is seated in the groove on the PTO shaft. A
loose shaft could slip off and result in personal injury or damage to the cutter.
If a slip clutch is incorporated in the driveline, it is designed to slip, absorb the shock load, and
protect the driveline and cutter. NOTE: Slip clutch units use a Grade 8 bolt to retain the clutch
to the gearbox shaft. Always use Grade 8 bolts when replacing.
As with any torque limiter, damage can still occur to the blades or drive train before they slip;
therefore, it is still the operator’s responsibility to ensure that the area is clear of any
obstructions that could damage the machine.
Prior to the initial start-up operation and after periods of inactivity, the slip clutches should be
“RUN-IN” before the cutter is used again. This can be accomplished by using the following
1. Carefully loosen each of the 8 spring retaining nuts by 2 revolutions.
2. Start the tractor and engage the PTO for 2-3 seconds two times to permit slippage.
Disengage the PTO, shut off the tractor, and remove the key.
3. Inspect the clutch and ensure the clutch plates have slipped. A clutch that has not
slipped must be disassembled to separate the friction disc plates.
4. Tighten each of the 8 spring retainer nuts 2 revolutions to restore the clutch to the
original setting pressure.
The manufacturer’s recommended setting for this clutch is a compressed spring length of 1.14”.
By performing this procedure, the operator makes sure that the clutches are performing
correctly and are set properly.
Use only AG-MEIER INDUSTRIES LLC blades. They are made specifically for this
cutter. Substitute blades
may not meet Specifications and could be dangerous.
For servicing of the blades, the manufacturer has provided and access hole in the cutter deck
All blades must be replaced or reground at the same time to maintain proper balance in the
cutting unit.
Keep all blade bolts tight and, for better cutting, keep all blades sharp. Inspect the 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.
Always disconnect the driveline from the tractor and block the cutter securely before working on
the blades or blade carrier.
Inspect the blade carrier frequently. After operation, check the blade carrier hub for tightness on
the gearbox output splined shaft. Keep all blade bolts tightened to 600 ft. lbs. and, for better
cutting, keep all blades sharp. Always use AG-MEIER INDUSTRIES LLC blades. When
replacing blades, check the cutting edges in relation to the blade carrier rotation. For removing
the blade carrier hub from the gearbox, use a drift punch through the access hole or gear puller.
DO NOT hammer on the end of the gearbox output shaft, as this may cause damage to the
1. Replace all blades at the same time to maintain proper balance in the cutting unit.
2. Order AG-MEIER INDUSTRIES LLC blades and blade bolt kit.
3. Torque blade bolt lock nut to 600 ft. pounds. And extended cheater bar may be required to
achieve proper torque.
1. Sharpen all blades at the same time to maintain balance. The difference the blade weight
should not exceed 1 ounce. Unbalanced blades will cause excessive vibration which can
damage gearbox bearings. Vibration may cause structural cracks in the cutter housing.
2. Examine bolts for excessive wear and replace if necessary.
3. Follow the original pattern of the blade.
4. Sharpen the blades by grinding. Do not heat and pound out the edge. Do not sharpen to a
razor edge, but leave a 1/16" blunt edge. Do not sharpen the back side of the blade. See
Figure 13.
NOTE: Care should be taken in order not to remove any more material than necessary when
sharpening the blades.
All blades should be sharpened at the same angle as the original cutting edge.
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 the suggested storage procedures.
1. Thoroughly clean the cutter
2. Lubricate the cutter as covered in the Maintenance Section.
3. Tighten all bolts to recommended torque.
4. Check the cutter for worn or damaged parts. Make replacements immediately using
Genuine AG-MEIER IND. L.L.C.
5. Store the cutter in a clean, dry place with the cutter housing resting on blocks.
6. Use spray touch-up enamel where necessary to prevent rust and maintain appearance
of the cutter.
