OUMX068,00004DF-19-19DEC13
Prevent Fires Please review these recommendations with all operators. See your
John Deere dealer with questions. Always follow all safety procedures posted on the machine and in
this operators manual. Before carrying out any inspection or cleaning, always shut off engine, set parking brake, and remove ignition key.
Besides routine maintenance, one of the best ways to keep your John Deere equipment running efficiently and to reduce fire risk is to regularly remove debris buildup from the machine.
After operating, allow machine to cool in an open area before cleaning or storing. Do not park machine near flammable materials, such as wood, cloth, or chemicals, or near an open flame or other sources of ignition, such as a water heater or furnace.
Completely remove any combustible materials from equipment before storing by emptying any grass catcher bags, containers, and cargo boxes.
Debris can accumulate anywhere on the machine, especially on horizontal surfaces. Remove grass and debris completely from engine compartment, muffler area, and from the mower deck or cutting units both before and after operating machine. Additional cleaning may be necessary when mowing or mulching in dry conditions.
In addition to cleaning machine before using and storing, keeping engine area clean provides the greatest impact on fire prevention. Other areas requiring regular inspection and cleaning include behind wheel rims, wire harness, hose or line routing, mowing attachments, etc. Compressed air, leaf blowers, or water assists in keeping these areas clean.
Safety
6
Frequency of these inspections and cleaning will vary depending on a number of factors, including operating conditions, machine configuration, operating speeds, and weather conditions (particularly dry, hot, and windy conditions). When you are operating in these conditions, inspect and clean these areas frequently throughout the day.
Excess lubrication or fuel/oil leaks or spills on the machine can also serve as collection sites for debris. Prompt machine repair and oil and fuel clean-up reduces the potential for debris collection.
Bearing failures or overheating can result in a fire. To reduce this risk, always follow the instructions in the machine operators manual regarding lubrication intervals and locations. Contact your local dealer if you have any questions about the lubrication intervals or location and if any unusual noises are coming from areas where bearings might be located. Washing the machine while warm may also reduce bearing life and increase potential for premature bearing failure.
Always shut off fuel when storing or transporting machine, if the machine has a fuel shutoff.
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.
OUO2005,0000221-19-27MAR19
Avoid Injury from Moving Parts
TCAL41683UN18JAN13
Keep hands, feet, clothing and other objects away from moving parts.
Do not attempt to remove any obstruction from tine area while aerator is in motion.
Keep hands and feet away from the tine area while the engine is running. When the engine is running, tining action will begin as soon as the aeration head begins to lower.
OUO1082,00064E0-19-15FEB13
Practice Safe Maintenance Only qualified, trained adults should service this machine. Understand service procedure before doing work. Keep area clean
and dry. Do not operate the engine in a confined space where dangerous
carbon monoxide fumes can collect. Never lubricate, service or adjust the machine or attachment while
it is moving. Keep safety devices in place and in working condition. Keep hardware tight.
Keep hands, feet, clothing, jewelry, and long hair away from any moving parts, to prevent them from getting caught.
Lower any attachment completely to the ground or to an existing attachment mechanical stop before servicing the attachment. Disengage all power and stop the engine. Lock park brake and remove the key. Let machine cool.
Disconnect battery or remove spark plug wire (for gasoline engines) before making any repairs.
Before servicing machine or attachment, carefully release pressure from any components with stored energy, such as hydraulic components and springs.
Release hydraulic pressure by lowering attachment or cutting units to the ground or to a mechanical stop and move hydraulic control levers.
Securely support any machine or attachment elements that must be raised for service work. Use jack stands or lock service latches to support components when needed.
Never run engine unless park brake is locked.
Keep all parts in good condition and properly installed. Fix damage immediately. Replace worn or broken parts. Replace all worn or damaged safety and instruction decals.
Check all hardware at frequent intervals to be sure the equipment is in safe working condition.
Do not modify machine or safety devices. Unauthorized modifications to the machine or attachment may impair its function and safety.

Operating Tips IMPORTANT: Always raise aerator first and then disengage PTO.
Do not reduce PTO rpm when aerator is temporarily raised out of the ground.
Around Greens and Teeboxes: Survey the green before aerating. Operate with PTO speed at 540 RPM. Do not operate at speed
below or above this speed. Plan your direction to minimize turning and maneuvering around
hazards at the end of a pass. Make the initial pass across the center of the green and work your
way to the outside. Keep PTO engaged and operating at 540 RPM when turning tractor
around to make another pass. Raise aerator only high enough to lift turf guards off the ground. Do not raise aerator to full 3 point hitch lift height.
Maintain consistent spacing while aerating a green by selecting a marking reference before starting.
On Fairways: Mark and/or flag all sprinkler heads and other items that could be
damaged or cause damage to the aerator. Start on the outside perimeter of the fairway and work your way to
the inside. Check for sand traps, water or other hazards before starting. Plan your direction to minimize turning and maneuvering around
hazards at the end of a pass. Avoid sharp turns while aerating. Keep PTO engaged and operating at 540 RPM when turning tractor
around to make another pass. Raise aerator only high enough to lift turf guards off the ground. Do not raise aerator to full 3 point hitch lift height.
Training: Practice before operating the aerator for the first time is critical to
quality performance. Read the operator manual to learn operating procedures.
Practice in an open field to become familiar with operating techniques necessary to maintain correct speed for proper hole spacing and hole quality.
General Operating Practice: Do not make sharp turns. Lift aerator out of ground to turn at the
end of fairway. Wait to aerate if the soil is too hard and compacted. Aerate after
rain or watering to achieve best results. Always carry extra tines and tools to replace a tine if it breaks while
you are aerating.

Aeration Hole Quality Coring Depth: Poor quality can result if the depth is set too deep.
Decrease the tine depth by 6 mm. (1/4 in) to 12.7 mm (1/2 in.) and check for improved hole quality.
Tine Type: Closed tubular tines will provide better quality holes than open-side tines. Use open-side tines in applications to overcome plugging in high sand-content soils or wet conditions.
Attachment Angle: Support legs provide the correct attaching angle at hook up for most conditions. Adjusting the angle too much or too little will be detrimentally affect hole quality. Adjusting angle too much can result in damage to the powershaft and/or gearbox.
Turf Guard: The turf guard needs to be firmly on the surface during operation or lifting may occur. This lifting is especially prevalent in turf with poor root conditions. Excessive turf guard pressure can cause marking in soft turf.
Damaged Aerating Linkage: If the hole quality is bad in one aeration linkage path only, then that associated linkage may have a damaged or missing part. First, inspect the linkage for any missing or loose hardware. Sometimes damaged linkage will make unusual

noise. Check for bent tines. Straighten or replace tines if needed. Replace linkage if needed.
Hole Spacing: Hole spacings greater than 76.2 mm (3 in.) can reduce the hole quality in some turf conditions.
Hard Soil: The aerator will raise up off the turf in hard soils conditions and the hole quality may be less than desirable.
Do not adjust hole depth deeper than what tines can penetrate, as damage can be incurred to all moving parts as well as Aercore frame.
OUO1082,00064EF-19-15FEB13
Pre-Operating Adjustments Level the aerator side to side. Adjust the aerator attachment angle side to side if necessary.
IMPORTANT: Do not raise 3-point hitch above 3/4 height while PTO is engaged or excessive wear to powershaft can occur. Raise to full height only when transporting the aerator with the PTO disengaged.
Set the rockshaft adjustable depth stop to the 3/4 position to prevent aerator from raising fully.
Adjust the speed of drop/lock valve so aerator lowers fairly quick without striking the ground abruptly.
Raise aerator slightly off the ground. Raise engine speed so that PTO speed is set to 540 RPM, and engage PTO. Check all moving parts for rubbing or interference. Disengage PTO, and turn off machine. Make any necessary adjustments.
OUO1082,00064F0-19-15FEB13
Checking Machine Ground Speed NOTE: Machine ground speed directly affects forward hole spacing,
quantity of holes, and rate of coverage. Operating within 2 - 4.8 km/h (1.2 - 3 mph ) is recommended for most soil conditions.
1. Select a location to test ground speed.
2. Measure a test area 30.5 m (100 ft) in length.
3. Operate machine at required engine speed for PTO to operate at 540 RPM. Select a low speed and drive machine 30.5 m (100 ft). Record the time required to travel the distance.
4. Make three passes, recording the time for each pass. The average time should be 30 - 40 seconds for most conditions. Average times for operating at the low and high end of the recommended speed range are as follows:
a. at 2 km/h (1.2 mph), average time traveling the test distance should be 57 seconds.
b. at 4.8 km/h (3 mph), average time traveling the test distance should be 23 seconds.
5. Adjust speed accordingly to achieve the best results.
OUO1082,00064F1-19-15FEB13
Adjusting Attachment Angle NOTE: The aerator support legs provide the correct attaching angle for
most soil conditions.
TCAL41281UN21JAN13
1. Loosen locking nut (A) and turn center link (B) to increase or decrease aerator angle.
2. Tighten locking nut to lock center link in position.
OUO1082,00064F2-19-15FEB13
Adjusting Tine Depth NOTE: Before determining tine depth adjustment is needed, make
sure adjustment roller and turf guards were contacting the ground during operation of the aerator. If aerator is not lowered completely, tine depth will be less than expected. Tine depth can be adjusted to a maximum 4 in. (10 cm). Depth adjustment must be the same on both sides of aerator. Damage may result if depth adjustment is set deeper than what tines can penetrate the ground.
1. Raise aerator so roller is off the ground before attempting to adjust depth.
TCAL41282UN21JAN13
2. Remove spring locking pin (A) securing the depth control position at both sides of aerator.
3. Turn adjusting handle (B) to adjust up or down to desired depth. Use depth indicator label (C) to determine tine depth. The adjustment must be equal on both sides.
4. Install spring locking pin (A) to secure depth control arms in position at both sides of aerator.

Adjusting Holes-Per-Square-Foot
TCAL41283UN21JAN13
Increasing the ground speed will reduce the number of holes per square foot, but will increase forward hole spacing (A) and increase the square feet aerated per hour.
Changing the tine holder from 4x holders to 3x holders will increase the tine hole spacing (B) and decrease the number of holes per square foot.
OUO1082,00064F4-19-15FEB13
Operating the Aerator IMPORTANT: Always raise aerator first and then disengage PTO.
Do not reduce PTO rpm when aerator is temporarily raised out of the ground.
1. Complete the pre-operating adjustments for the aerator and remove the support legs if installed.
2. Start the engine.
3. Raise aerator so turf guards are slightly off the ground.
4. Set machine range shift lever to low gear.
5. Set machine at required engine speed for PTO to operate at 540 RPM.
6. Unlock the park brake.
7. Obtain proper ground speed.
NOTE: Operate with PTO speed at 540 RPM. Do not operate at speed below or above this speed.
8. Engage rear PTO.
9. Engage cruise control or optional speed control kit, if equipped, to maintain consistent ground speed.
IMPORTANT: Adjustment roller must make contact with turf surface for proper operation. Roller coming off the ground indicates tine depth is adjusted too deep. Damage to aerator can occur if depth is adjusted deeper than what tines can penetrate.
TCAL41284UN21JAN13
10. Lower aerator so adjustment roller (A) contacts the ground by moving 3-point raise/lower lever completely forward.
11. Maintain engine speed for PTO to operate at 540 RPM.
12. To raise the aerator at the end of a pass:
a. If turning around to make another pass, raise aerator just high enough for turfguards to clear the ground, do not disengage PTO and maintain PTO speed of 540 RPM.
b. If not turning around to make another pass, raise aerator and then immediately disengage PTO.
