OPERATION SAFETY
• Your Safety Is Always First! Familiarize yourself with the safety symbols and decals on pages 3 and 4.
•
All operators should read and understand the following sections of this manual prior to adjusting, maintaining, hitching to, or operating the AERA-vator:
OPERATION SAFETY, OPERATOR INSTRUCTIONS, PRE-OPERATION
CHECKS, MAINTENANCE CHECKS, MAINTENANCE SAFETY, OPERATOR
MAINTENANCE.
• In addition, remove and read the drive line safety and maintenance manual taped to the drive line shield. After reading the drive line manual, place it inside this manual for reference.
• For the safety and instruction of all operators, keep this manual stored on the AERAvator at all times.
• Never attempt to adjust, maintain, or remove debris from any moving part of this machine while it is attached to a tractor or other power source with the engine running.
• After operating, always disengage the power take off and switch the engine off prior to dismounting from the tractor or other power source and approaching the unit.
• Prior to starting, always inspect operating area for any hazards such as large rocks, steep slopes, low tree branches or wires. Flag objects difficult to see such as irrigation heads and water meters.
• Instruct all people in the work area to stay clear of the unit.
• Perform all pre-operation checks (page 8) prior to start up.
• Never engage the power take off while the rotors are off the ground. Always disengage the power take off before lifting the unit. High-speed rotors create a flying object hazard when they are lowered to the ground.
WARNING
* TO PREVENT A THROWN OBJECT HAZARD,
DO NOT ENGAGE PTO IN LIFTED POSITION.
* TO PREVENT A ROLL OVER HAZARD, DO
NOT LIFT UNIT ON HILLSIDE.
Figure 1. Tractor Roll Over/Thrown Object Warning

• Consult your tractor Operator's Manual regarding operation on slopes. Do not lift the unit while the tractor is moving (or parked) sideways on slopes above 5
°. The swing hitch may allow the unit to swing to the downhill side and cause the tractor to roll over. On slopes from 5
° to 15° always aim the tractor uphill before lifting the unit.
We do not recommend the unit being used on slopes above 15
°.
• Use extreme care and maintain moderate ground speed when transporting or operating on slopes, over rough surfaces, or close to trees ditches and fences.
• Only operate during daylight hours or with good artificial light.
• The AERA-vator is not equipped for highway use. Be careful of traffic when operating near or crossing roadways.
OPERATOR INSTRUCTIONS
• The AE-80 AERA-vator is designed to attach to a tractor with a category one three point hitch, 540 PTO, and a minimum of 35 horsepower. However, additional attachments (roller, seeder, etc.) may require a larger tractor for increased lifting capacity. Check the tractor owner and operator’s manual for lift capacity. The weight of the AE-80 and its attachments are listed in Specifications, page 31.
•
Before hitching to the AERA-vator familiarize yourself with all of the tractors control functions. Be prepared to stop the tractor movement, PTO operation, and the engine quickly in an emergency.

UNDERSTANDING HOW THE SWING HITCH OPERATES
(PRIOR TO HITCHING TO TRACTOR)
With the swing stand lowered and the swing mast rearward to disengage the swing lock, grasp the hitch pins and rotate the
“A” frame to simulate operation in a sharp turn. Release the hitch pins and slowly pull the swing mast forward as it would be pulled by the top link during lifting. Notice how one mast chain tightens causing the
“A” frame and unit to realign and the spring on the lock link is compressed to make the swing lock engage upon alignment. Now push the swing mast rearward against the lock
Figure 2. Swing Hitch Operation link tab to disengage the swing lock and loosen the chains to allow sharp turns again.
This demonstrates how the top link of the tractor lift system switches the AERA-vator between the trail and lift modes.
CORRECTLY ADJUSTING THE HITCH TO THE TRACTOR
A category 1 hitch tractor is required with the lower links stabilized. With the AERAvator swing stand lowered connect the lower lift links to the “A” Frame and top link to the swing mast. Push the lift control lever on the tractor to the completely lowered position.
Lengthen the adjustable top link until the swing mast closes tight against the “A” Frame and the
AERA-vator swing stand is lifted 1/8 to 1/4 inch off the ground. This causes the combined weight of the AERAvator and the tractor hitch components to be transferred to the tines. This extended top link also
Figure 3. Hitch Adjustment causes the
7
AERA-vator to tilt backwards when lifting allowing gravity to assist the swing chains in aligning the unit with the tractor. DO NOT ADD ADDITIONAL WEIGHT TO THE
AERA-vator OR APPLY DOWN PRESSURE TO THE TRACTOR LIFT LINKS
DURING OPERATION.
• The geometry of tractor lift linkages varies, and a trial run over uneven ground is recommended. Ideally the swing lock will not engage when aerating over the crown of a hill and the tractor hitch is always free to float upward at all times. The tines should clear curbs etc., when lifted.
• When lowering for operation, lower slowly until the tines touch the ground. Then swiftly push the lift control lever on the tractor to the completely lowered position to instantly unlock the hitch. This is especially true when lowering the unit in a sharp turn. Failure to do this may cause the swing hitch not to disengage, resulting in damage to the machine and/or turf damage. In the event the unit should fail to unlock for trail mode, stop the tractor and repeat the lowering procedure.
DO NOT TURN THE TRACTOR WITH THE AERA-vator IN THE GROUND AND THE
SWING LOCK ENGAGED. DAMAGE TO EQUIPMENT MAY OCCUR!
• When operating diagonally downhill or transversely (sideways) on a hillside slope above 5
° the mast chains will not swing the unit uphill to center and lock on the tractor when the unit is lifted. Occasionally the unit will swing farther to the downhill side of the tractor creating the hazard of tractor roll over. If the tractor ever seems unstable, immediately lower the hitch and steer the tractor uphill or on a more level surface where it will center and lock when lifted.
• Do not back the unit up with the AERA-vator touching the ground. Always disengage the PTO, raise the unit, back to desired location and then lower the machine and engage the PTO.
• The operating ground speed of the tractor will depend on the amount of soil agitation required. Slower tractor ground speed (lower gears) will be used for renovating in extremely hard dry ground. Faster tractor ground speeds (higher gears) will be used for aeration work in normal conditions. To reduce the amount of soil agitation simply reduce the engine RPM. Three to four miles per hour is the most common speed range.
PRE-OPERATION CHECK LIST
(With the AERA-vator lowered and the tractor engine switched off...)
• Be sure that the implement is hitched to the tractor properly with all pins in place.
• Pin the swing stand in the up position.
8
• Be sure the driveline is correctly assembled.
(The end stenciled as the tractor end is connected to the tractor and not to the AERA-vator). Check to see that the end yokes are locked to the tractor PTO and gearbox shafts. Drive shields must turn freely on the driveline.
• See that all shields are correctly installed.
• Remove any debris caught in the rotors.
• Check gearbox oil level before first operation and every 200 hours of operation thereafter. (Refer to operator maintenance section.)
MAINTENANCE SAFETY
• Never attempt to clean, adjust, lubricate or perform any maintenance on the AERAvator while it is attached to the tractor or any other power source with the engine running.
• Read and understand all safety decals prior to performing any maintenance.
Replace any safety decals which are not legible.
• Never attempt to clean, adjust, lubricate or perform any maintenance on the AERAvator while it is attached to the tractor in the raised position unless safety blocks are inserted under the frame.
• When not attached to the tractor, always use the lifting hook to hoist the machine for maintenance. (See Figure 4). Use extreme caution when using lifting hook because center of gravity is affected by additional attachments and the unit may shift rearward. Do NOT hoist the machine with the seeder attached.
• When installing tines, performing any rotor shaft service, or removing debris from the rotors, ensure
Figure 4. Swing Stand/Lifting Hook that the rotor shaft does not rotate because a serious pinch injury could occur.

OPERATOR MAINTENANCE
• Check gearbox oil level before first operation and every 200 hours of operation thereafter. With frame level, remove oil level plug on front left side of gear box using
5/16” x 6” allen wrench through slots in the frame post. If required, add 90w-gear oil through plug in top of box until it appears at oil level plug. Replace both plugs securely.
• Grease driveline parts after the number hours use as shown in the following chart.
Figure 5 Drive Line Lube Chart
• The hitch flex joints at the top of the “A” frame and above the gearbox (see page 18) should be lubricated before first operation and weekly thereafter.
• After the first two hours of operation tighten all tines to 210-ft. lbs. Check for loose tines daily.
• When replacing lost or worn tines use a 15/16” extra deep socket (Socket is available through our repair parts. Order # AE60T003) and torque to 210 ft. lbs.
• CHECK BELT TENSION every 4 hrs. of operation for the first 12 hrs. and every
100 hrs. thereafter. Also, tighten belts if shaft hesitation is noticed during operation.
Over tightening belts may cause damage to the machine. Be sure to re-install belt shield after servicing.
• Use the applicable parts break down illustration pp.17-30 for maintenance removal, and assembly instructions.
• The AERA-vator shaft and rotor bearings are sealed and permanently lubricated requiring no routine maintenance.

AE-80 ROTOR SHAFT SERVICE INSTRUCTIONS
(Clean the machine thoroughly with a pressure washer)
Rotor Shaft Removal
(This will require a tractor with 3-point lift or overhead hoist. For safety reasons, only lift the
Aera-vator approximately two inches above the work surface, never place hands or feet
between the machine and the work surface).
The AE80 consists of two complete shaft assemblies and each shaft assembly can be removed separately. The following instructions are directed toward the removal of a single shaft. However, both shafts can be removed at the same time by completing each step of the procedure on each shaft before proceeding to the next. Alternatively, one shaft can be removed and then the other.
1. Remove belt cover, skid shoe and drive belts.
2. Remove 1/2” carriage bolts holding center-bearing support to main frame.
3. Remove 3/8" carriage bolts holding end rotor shaft bearing, drive end. (See Figure 6)
4. Move frame slightly to right and lift off of rotor shaft assembly.
Rotor Shaft Disassembly
1. Remove the 1-1/8" hex jam nut from the shaft end nearest to the damaged component.
2. Only remove the rotors and spacers required to reach the damaged component. Wipe the shaft clean before each rotor is removed. Each rotor bearing has two separate cones with a hex bore adapter pressed in each. Each cone is held in position by an internal grease seal, which allows the cones to be moved apart slightly. When they are moved apart any dirt allowed inside the hex adapters can fall between the cones and contaminate the bearing. If the cones are forced apart the internal seals become ruined and irreplaceable.

Rotor Hub Re-Assembly
(Keep all components clean to prevent bearing contamination)
1. Install internal snap ring in one side of rotor hub. Be sure snap rings expand full depth into
grooves.
2. Press new bearing and adapter assembly down tight against snap ring as shown in Fig. 9.
If bearing is loose in hub the rotor should be replaced.
3. Install snap ring in other end.
4. Apply a ribbon of general-purpose grease between the snap ring ID and bearing adapter OD on both ends of the rotor hub.
5. With the press tool inverted to fit the external seals, press the seals in both ends of the rotor
with the lips out. Wipe off excess grease. Be sure seals are not bent or cut and are seated firmly. If the seals are not tight, use a hammer and punch to stake the hub faces at
about 90
° intervals.

Rotor Shaft Re-Assembly
(Read this section thoroughly before beginning)
CAUTION: IF THE BEARING ADAPTERS ARE NOT PRECISELY TIMED 180
DEGREES APART IN EACH ROTOR AND ALIGNED BETWEEN ROTORS, SERIOUS
DAMAGE WILL RESULT.
1. Rotate the adapters in each rotor so the timing marks (See Figures 6, 10 &
11) are phased 180 degrees apart with hex bores aligned.
2. Use marker pen to assist with aligning timing marks between rotors.
Mark two rotor shaft flats 180 degrees
Figure 10. Timing Mark apart next to the threaded end (See Figure 11). The marked flats would have to align with the timing marks on any rotors not removed during servicing.

3. Install the required components in the sequence shown in Figure 11, double checking the timing mark locations and spacer lengths (see following table) as each rotor is installed.
CAUTION: CLEAN THE ROTOR SHAFT THOROUGHLY REMOVING ANY BURRS
THAT WOULD KEEP THE ROTOR ASSEMBLIES FROM SLIDING ON FREELY. IF A
BEARING ADAPTER JAMS, THE INTERNAL BEARING SEAL COULD BE FORCED
OUT AND IT IS NOT REPLACEABLE.
NOTE: THE SPACERS MUST BE FULLY SEATED IN EACH ADAPTER
COUNTERBORE BEFORE TIGHTENING. DO NOT FORGET TO PLACE THE
BEARING STAMPINGS ON EACH OF THE SHAFT BEARINGS DURING
REASSEMBLY. ALSO, THE 3/8" CARRIAGE BOLTS SHOULD BE PLACED IN THE
BEARING STAMPINGS ON THE DRIVE END OF THE SHAFT BEFORE THE PULLEY
IS REPLACED.
4. Replace the 1-1/8" hex jam nut and rotate each rotor occasionally as the nut is torqued to 350 ft-lbs. If any rotor locks up, the bearing adapters in the rotor are probably not phased 180 degrees apart or the spacers are not fully seated.

Rotor Shaft Installation
1. Roll Rotor Shaft Assembly into position under frame bearing holes with pulley on drive end.
2. Carefully lower unit in small increments while keeping both bearing flanges on the side of the frame end plate and center bearing support.
3. Note that as the frame ends and center bearing support are carefully lowered down beside each pair of bearing flanges it is necessary to push the unit away from the pulley end. This allows the frame end to pass the carriage bolts sticking through both bearing flanges next to the pulley.
4. When the frame ends align with the carriage bolt holes and the bearing flanges, pull the unit toward the pulley end to assemble nuts on carriage bolts.
5. Install bolts and nuts in center bearing support and other end plate being careful to align carriage bolt shoulders with the square holes in bearing flanges (hand tighten).
6. Tighten all bearing flange bolts 30-35 Ft-Lbs.
7. Tighten 3 bolts connecting center bearing support to frame 50-55 Ft. Lbs.
8. Install and tighten drive belts. Tighten both bolts in belt idler bracket 30-35 Ft. Lbs.
9. Install Skid Shoe and tighten bolts 15-20 Ft. Lbs.
10. Install Belt Cover and tighten bolts 8-12 Ft. Lbs.
11. Run the machine and check for loose or improperly installed components.
