WARNING

• Do not attempt to attach aerator with tractor’s

engine running.

• Do not stand between tractor and aerator with

engine running.

• Do not attempt to raise and lower tractor hitch

while standing between aerator and tractor.

4 INITIAL INSPECTION AND SET UP

4.6 SHORTENING PTO SHAFT __________________________________________________

1. The PTO shaft supplied is longer than required for

your tractor and must to be shortened to the correct

length.

a. Always cut equal amounts off each telescoping

tube and the cover. Ensure that when cut each

the tubes overlap each other by at least 1/3 of its

length in the maximum extended position.

b. The telescoping tubes must not bottom out on

the universal joint when raising or lowering the

aerator or damage will result.

2. Move machine and tractor to a level surface. Fully

lower the aerator and retract the top link completely.

Measure the distance (A) between the locking

groove on the tractor shaft and the locking groove

on the gearbox shaft. Repeat measurement with top

link fully extended. Fully raise the aerator, and take

measurements with top link fully extended and

retracted. Use the shortest measurement.

[Example: 26 in. (660.4 mm)]

3. Slide PTO halves completely together. Measure the

distance (B) between the center of the locking collar

on the tractor end of the PTO shaft and the center

of the pin hole on the clutch end of PTO shaft.

[Example: 28 in. (711.2 mm)]

4. Subtract the distance between PTO locking grooves

(A) from the distance between locking points (B). To

prevent the PTO shaft from bottoming out, add 1-1/2

in. (38 mm) to the result. This is the amount to be

removed from each shaft (C).

[Example: 28 in. - 26 in. = 2 in.]

[2 in. + 1-1/2 in. = 3-1/2 in. (88.9 mm)]

5. Separate the two halves of the PTO and remove the

cover shields.

6. Cut the determined length (C) from both halves of

PTO shaft. Remove any burrs and metal shavings

from both inner and outer tubes. Apply grease to the

inside of the outer tube and the outside of the inner

tube. PTO halves must slide together easily.

NOTE: Failure to clean and lubricate PTO shaft tubes

can result in damage to tractor PTO shaft and aerator

gearbox. For proper operation of the telescoping shaft,

equal amounts must be removed from both halves.

7. Assemble cover shields onto appropriate PTO

halves. Cut the safety shields so there is 1 in. (25.4

mm) of PTO shaft extending past end of shield.

8. Assemble the PTO shaft. Replace any decals that

were damaged by cutting PTO and shields.

9. Extend the top link.

10. Connect the PTO shaft to the aerator first and then

to the tractor. Fully raise and lower aerator and

extend and retract the top link in both positions, to

be certain PTO shaft does not bottom out or over

extend.

4.7 MOUNTING ADJUSTMENTS _________________________________________________

Refer to the tractor’s manuals for performing the

following adjustments. Setup and testing of the unit

should be done in a test area of turf.

1. Set the tractor hydraulic lift “lowering speed control”

to prevent the aerator from being lowered too quickly.

2. Set the hydraulic lift lever stop to control maximum

lift for operation (Roller should be 5 in. (127 mm) off

the ground). When raised, the tines are clear of the

ground and when lowered the aerator roller is firmly

on the ground.

3. The aerator must be centered and level on the

tractor. Tighten the tractor lift arm check chains to

prevent the aerator from swaying side to side.

4. Keep all tractor and aerator guards in place and

secure.

5. Operate the unit in a test area to become familiar

with the operation and handling of the machine.

NOTE: Jacobsen recommends that the machine is set up

and operated for the first time without tines installed. DO

NOT operate this machine without the roller on the

ground.

4.8 TINE INSTALLATION _______________________________________________________

1. Make certain the aerator is fully supported on stands.

If connected to a tractor, the parking brake should be

set and engine shut off.

2. Loosen the clamping bolts. Remove any previous

tines if installed.

3. Slide the proper size tine into holes in mounting

head until it bottoms out. Never use a smaller

diameter tine without the proper size adapters.

a. Coring (hollow) tines should be installed with

ejection slot towards the rear of the aerator.

b. Solid tines should be installed with the angled

face towards the front of the aerator.

4. Tighten clamping bolts

5. Adjust camber brackets as required for tines

installed. Section 6.4

6. Operate unit in a test area to fine tune adjustment

and achieve the desired hole spacing and surface

finish.

4.9 DETERMINE PROPER ENGINE SPEED ________________________________________

The aerator is designed to operate with a PTO speed

below 450 RPM depending on the size/weight of the

tines. Most tractors indicate a 540 RPM position on the

engine tachometer. Since the engine and PTO RPM’s

are directly proportional, you can determine the engine

RPM required for the desired PTO output.

Example:

Desired PTO speed = 400 RPM

Engine RPM with 540 RPM PTO speed = 2700 RPM

(Engine RPM at 540 PTO Speed) x = Engine RPM

In this example, running your tractor’s engine at 2000

RPM, will have a PTO speed of 400 RPM.

WARNING

Before you clean, adjust, or repair this equipment,

always disengage all drives, lower the aerator onto

stands, engage parking brake, stop engine and

remove key from ignition switch to prevent injuries.

Never install or remove tines by climbing under the

aerator. Tine must be installed standing behind unit,

as far back as possible in case unit is accidently

lowered

To prevent injury, wear gloves when installing or

removing tines. Tines may have sharp edges.

5 OPERATION

5.1 OPERATING PROCEDURES_________________________________________________

1. Under no circumstances should the engine be

started without the operator seated on the tractor.

Never start the engine with operator or bystanders

standing behind the aerator.

2. Never run the engine in an enclosed area.

3. Keep hands and feet away from moving parts. Do

not make adjustments with the engine running.

4. Do not attempt to adjust a fixed top link while the

machine is in operation or the engine is running.

5. Do not operate tractor or attachments with loose,

damaged or missing components. Whenever

possible aerate when grass is dry.

6. First operate in a test area to become thoroughly

familiar with the operation of the tractor, aerator and

control levers.

7. Study the area to determine the best and safest

operating procedure. Consider the type of terrain,

and condition of the surface. Each condition will

require certain adjustments or precautions.

8. Avoid operating near under ground services such as

water pipes, gas pipes or electric cables. Mark

locations of sprinkler heads and other known above

or below ground obstructions.

9. If aerating unknown or stony ground, set your depth

cautiously to avoid hammering the tines into hard

underground obstructions, as this will damage the

machine. If a hydraulic top link is used, reduce

penetration quickly if an underground obstruction is

encountered

10. Be aware of discharge direction and never direct

discharge of material toward bystanders. Never

allow anyone near the machine while in operation.

The owner/operator is responsible for injuries

inflicted to bystanders and/or damage to their

property.

11. Use discretion when operating near gravel areas

(roadway, parking areas, cart paths, etc.). Stones

discharged from the implement may cause serious

injuries to bystanders and/or damage the

equipment.

12. Disengage the PTO as soon as the roller lifts off

the ground.

13. Disengage the PTO, raise the aerator and slow

down when crossing paths or roadways. Look out

for traffic.

14. When transporting between work areas, always

proceed slowly and carefully, maintaining control of

the tractor.

15. Do not over extend the top link. This may cause

the tine heads to hammer the turf,

16. Stop and inspect the equipment for damage

immediately after striking an obstruction or if the

machine begins to vibrate abnormally. Have the

equipment repaired before resuming operation.

17. Slow down and use extra care on hillsides. Read

Section 5.6. Use caution when operating near drop

offs. To prevent overturning machine, avoid turning

on slopes. The aerator is heavy and changes the

handling of the tractor, particularly when raised.

18. Never operate the aerator in reverse

or severe

damage will occur. Disengage PTO and fully raise

aerator. Look behind and down before backing up to

be sure the path is clear. Use care when

approaching blind corners, shrubs, trees or other

objects that may obscure vision.

19. Never use your bare hands to clean, remove or

install tines. Use a brush to remove dirt and debris.

Tines edges may be extremely sharp and can cause

serious injuries.

CAUTION

To prevent injury, always wear safety glasses, leather work shoes or boots, a hard hat, and ear protection.

CAUTION

Before aerating, pick up all debris such as rocks, toys

and wire which can be thrown by the machine. Enter a

new area cautiously. Always operate at speeds that

allow you to have complete control of the unit.

WARNING

Before you clean, adjust, or repair this equipment,

always disengage all drives, lower aerator onto

stands, engage parking brake, stop engine and

remove key from ignition switch to prevent injuries.

OPERATION 5

5.2 STOPPING / PARKING______________________________________________________

To park the tractor under normal conditions:

1. Raise the aerator. When aerator roller lifts off the

ground, disengage the PTO then continue to raise

the aerator to the transport position and move away

from the area of operation.

2. Drive the tractor to the aerator stands.

a. Bring the tractor to a complete stop.

b. Disengage all drives, lower aerator onto stands

and engage parking brake. Secure aerator to

stands. Follow tractor engine shut down

procedure provided with tractor. Always remove

the ignition key.

If an emergency arises and the tractor must be parked in

the area of operation, follow the guidelines outlined by

the grounds superintendent.

5.3 TO DRIVE / TRANSPORT____________________________________________________

Read and follow all safety notes contained in this manual

when driving or transporting tractor. Never operate

aerator in reverse. When backing up, look behind you to

ensure you have a clear path.

Important: If this tractor is driven on public roads, it must

comply with federal, state and local ordinances. Contact

local authorities for regulations and equipment

requirements.

To raise aerator to transport position:

Raise the aerator. When aerator roller lifts off the ground,

disengage the PTO then continue to raise the aerator to

the transport position.

Important: The PTO must be disengaged while aerator

is raised.

5.4 AERATING _______________________________________________________________

To aerate:

1. Align the tractor for the first pass you wish to aerate.

2. Always aerate with the tractor engine running at

correct RPM setting. Section 4.9

3. Partially lower the aerator to a position just before

the tines contact the turf.

4. Engage the PTO and the desired gear on the tractor

and begin to move forward.

5. Immediately lower the aerator until the aerator roller

is firmly on the ground.

6. If the hydraulic top link is installed, extend link to

aerate at proper depth. If operating on undulating

ground, extend or retract the hydraulic top link to

maintain a constant aeration depth. Section 6.2

NOTE: Do not over extend the top link as this will cause

the tine heads to hammer the ground.

7. The aerator can work in both straight lines and

gentle curves to follow the contours of the playing

field.

8. At end of each pass, while still moving forward,

raise the aerator and disengage the PTO when the

roller lifts off the ground. Raising the aerator on the

move reduces turf disturbance and leaves a cleaner

finish.

If hydraulic top link is installed, retract the cylinder

before raising the aerator. This will give you greater

clearance between the tines and turf when

maneuvering over undulating ground.

WARNING

To prevent serious injuries, keep hands, feet and

clothing away from aerator when the PTO is engaged.

NEVER use your bare hands to clean, remove or

install tines. Use a brush to remove dirt and debris.

Tines edges may be extremely sharp and can cause

serious injuries.

NEVER operate machine in reverse. NEVER operate

the machine when in the raised position. DO NOT

operate this machine without the roller on the ground.

DO NOT operate aerator without rear shield or PTO

shields installed.

CAUTION

Do not attempt to adjust a fixed top link while the

machine is running. When using a fixed top link, the

aerating depth must be set in advance and can not be

adjusted during operation.

5 OPERATION

5.5 SUBSOIL CULTIVATION ____________________________________________________

Subsoil cultivation, fracturing or “heave” is created by a

forking motion of the tine in the soil as the aerator and

tractor move forward. Maximum heave is achieved with

long, large diameter solid tines.

Quality of finish

on the playing surface after aerating will

depend on various factors, including turf condition, root

growth and moisture content. The best results will be

achieved if the tines are vertical or tilted slightly to the

rear of the machine as it enters the soil. Tine tilt is

adjusted with the camber bracket [Section 6.4]. Never

have tines tilted under the machine. This will cause

damage to the camber brackets.

Aerating quality is better at speeds below 2 mph (3.2

kph). An initial forward speed of 1 mph (1.6 kph) is

recommended. Local turf conditions and hole spacing

requirements however may respond better to a different

speed.

For best results aerating greens, use 2 to 3 in. (51 to 76

mm) front to rear hole spacing with tines at their

maximum depth.

For aerating fairways, use 4 to 6 in. (102 to 152 mm) front

to rear hole spacing. 7 to 8 in. (178 to 203 mm) hole

spacing indicates you are traveling too fast.

5.6 HILLSIDE OPERATION _____________________________________________________

Refer to your tractor manual for proper hillside operation

and slope limitations. Do not exceed the maximum slope

recommended by the tractor manufacturer.

1. Always aerate with the tractor engine running at cor-

rect RPM setting. Section 4.9

2. If the tractor tends to slide or the tires begin to

“mark” the turf, angle tractor into a less steep grade

until traction is regained or tire marking stops.

3. If tractor continues to slide or mark the turf, the

grade is too steep for safe operation. Do not make

another attempt to climb, raise aerator, disengage

PTO and back down slowly.

5.7 HOLE SPACING ___________________________________________________________

Front to rear spacing is a function of tractor gearing.

Some creeper gears will allow as low as 1 in. (25 mm)

spacing. Spacing greater than 8 in. (203 mm) is not

recommended in order to achieve proper aeration/

cultivation.

Because forward travel speeds and PTO speeds are

both directly tied to engine RPM, hole spacing should

remain constant for each gear, regardless of engine

speed.

Locate the desired hole spacing in the chart. Calculate

the engine speed required to match the desired PTO

speed (Section 4.9). Select the proper gear for your

tractor to match the correct speed for the desired hole

spacing.

If a ground speed chart or decal is not available for the

determined engine/PTO speed, the tractor’s ground

speed in mph can be calculated by measuring the

distance in feet traveled in 15 seconds and multiply by

0.0454545. When measuring the distance, engine must

be running at the determined speed.

Example: (Calculating mph)

Distance travelled in 15 seconds = 15 ft

15 ft x 0.0454545 = 0.68 mph

The tractor’s ground speed in kph can be calculated by

measuring the distance in meters traveled in 15 seconds

and multiply by 0.24. When measuring the distance,

engine must be running at the determined speed.

Example (Calculating kph)

Distance traveled in 15 seconds = 4.572 m

4.572 m x 0.24 = 1.097 kph

WARNING

To minimize the possibility of overturning, the safest

method for operating on hills and terraces is to travel up

and down the face of the slope (vertically), not across the

face (horizontally). Avoid unnecessary turns, travel at

reduced speeds, and stay alert for hidden hazards.

OPERATION 5

Hole spacing that is shaded in black is not recommended

5.8 AERATOR REMOVAL ______________________________________________________

1. With aerator fully raised, Install stands provided with

the aerator. Remove all tines from aerator. Lower

aerator until it is resting on the stand. Apply parking

brake, shut off tractor engine and remove the key.

2. Open the PTO cover and disconnect the PTO from

the tractor. Secure the PTO to the aerator’s “A”

frame.

3. Disconnect the top link from aerator.

4. Disconnect lower lift arms from aerator.

5. Start tractor. Slowly and carefully pull away from the

aerator.

6. Insert pivot pins and hairpins into aerator mounting

holes for storage.

5 OPERATION

5.9 DAILY MAINTENANCE _____________________________________________________

Important: For more detailed maintenance information,

see the Adjustments and Maintenance sections of this

manual.

1. Park the tractor on a flat and level surface. Fully

lower the aerator onto stands, engage parking brake,

stop the engine and remove the key from ignition

switch.

2. Grease and lubricate all points if required. To

prevent fires, wash the aerator after each use.

3. Inspect top link hydraulic hoses and tubes daily.

Look for wet hoses or oil spots and replace worn or

damaged hoses and tubes before operating the

aerator.

WARNING

To prevent serious injury from hot, high pressure oil,

never use your hands to check for oil leaks, use paper

or cardboard.

Hydraulic fluid escaping under pressure can have

sufficient force to penetrate skin. If fluid is injected into

the skin, it must be surgically removed within a few

hours by a doctor familiar with this form of injury or

gangrene may result.
