TO THE OWNER
Congratulations on the purchase of your new AerVator soil aerator.
Your new AerVator is designed to meet your agricultural aeration requirements. The
ease of operation and low maintenance will give you many trouble free hours of
operation.
Make certain that you read and understand the important instructions for the
adjustments, operation and the maintenance contained in this manual. If there are
any instructions which you do not fully understand, contact your Dealer for
clarification prior to using the unit.
When in need of replacement parts, specify the model and serial number of your
AerVator.
To give you many years of service, regular preventative maintenance should be
performed, ie lubricate bearings, touch up painted areas susceptible to rust and
corrosion, and store implement in a dry place in off-season when not in use.
We wish you many years of profitable use from our equipment.

FARM TECH AERVATOR
WORK SAFELY - FOLLOW THESE RULES !
A CAREFUL WORKER IS THE BEST INSURANCE AGAINST AN ACCIDENT
** BEFORE HANDLING THIS EQUIPMENT, READ THIS OPERATIONS MANUAL **
1. Hands, feet, clothing and other objects must be kept away from all moving
parts.
2. Use care when making adjustments.
3. Use the tool suppliedor the correct equipment for the job at hand.
4. When working under or around the tines, the frame must be supported.
5. When not in use, the 3 point linkage unit should have the jackleg extended down
and the safety pins engaged. This will prevent the implement from
tipping when detached from the tractor.
6. Prior to lowering and unhitching, lower the jack leg(s) and insert the jack safety
pin.
7. Remove tools, parts and maintenance equipment after servicing the unit.
8. Before and during operation the area should be checked to ensure that the
area is clear of both obstacles, hazards and personnel.
* KNOW WHERE AND HOW DEEP YOUR GAS, WATER AND ELECTRICAL
LINES ARE BURIED.
9. Caution should be exercised when operating close to ditches, fences
or on hillsides.
10. WARNING: Do not over ballast the weight box. This will result in the loss of
front steering and the tractor stability. In some instances, extra front counter
balancing may be required.
11. No riders other than the tractor operator. Never allow anyone to ride on the
AerVator frame at any time.
12. Do not attempt to remove obstructions while the AerVator is in motion.

AERVATOR – FIELD USE
1. Once in the field, lift the 4 jack stands then lower the machine to the ground.
2. Move forward to allow tines to penetrate the ground.
3. Once at best operating depth, check that the frame is level by adjusting both the top link
arm and level box on RH lift arm, as required.
4. On AV Series 100 units, more weight may be added to get extra penetration. Penetration
depth is governed by soil hardness due to dryness and compaction.
Note:
If a depth of only 60cm or so is achieved in hard soil conditions on the first pass, don’t
despair ! The first rain or irrigation will allow water into soil and not run off. Tine shatter
will occur and moisture will disperse into the soil starting the recovery of hard pan.
5. Cross working:
If possible, work at 90 degrees to the previous aerating direction. This gives superior results.
Working the same direction - move tractor over 1 - 2 metres to run on fresh tracks.
6. Frequency of working:
Depending on soil condition the frequency of aeration in a year will vary. The following gives
some guidelines:
A. Average soil conditions -
Once in Autumn, once in Spring.
Twice a year is an ideal annual maintenance program.
B. Hard soil conditions -
Work ground to best depth, use extra weight if necessary.
Waiting for “better” conditions is not necessarily a good idea, as the initial runover with
an Aervator will allow the next rain or irrigation to move into the soil.
Second and third workings can be planned to follow on after rain to meet aeration
targets.
7. Gang Settings:
ZERO -
This is a neutral setting.
Use only where a slot in the ground is required with little aeration.
Generally should not be used.
AERATE -
Setting 1 Most popular setting for aeration. Does not cause a lot of soil pick up off the tine.
Setting 2 This setting gives a lot more aggressive aeration and soil movement.
This gives a larger divot off the tine.
AERATE & CULTIVATE -
Setting 3 Light cultivation and aeration.
Depending on soil condition and speed of implement (ie 10kph or more).
Setting 4 Aggressive cultivation and aeration.
This setting gives good soil movement for cultivation, again depending on soil
condition and speed of implement.
ZERO AERATE CULTIVATE

AERVATOR – FIELD USE (cont’d)
8. LINKAGE MACHINES -
In stoney conditions, it is advisable to set the Tractor lift arms to the slide position (refer to
Tractor Manual as necessary). Most Tractors have a locating pin on the connecting link from
the lower linkage arm to the top lifting arm. The pin can be turned 90 degrees from the solid
position to sliding position. This allows each lower linkage arm to move independently so the
Aervator can walk over obstructions and reduce potential for breakage.
9. TRAILING MACHINES -
Adjust top link on drawbar to level the machine for working.
NOTE: This arm can be shortened to give more transport clearance.
Use lock out tap on hydraulic line for transport to release the hoses. Fit transport lockouts for
road transport.
For maximum weight transfer lift rear wheels off the ground.
Use wheels for depth control if less than full depth required.
10. TOW HITCH -
Welded tongue on rear bar, standard.
A floating tow hitch for pulling combine or other implement, available as optional extra.

HITCHING YOUR AERVATOR TO A TRACTOR
1. Set up the Aervator on level ground and stand on all 4 jack stands.
2. Reverse the tractor up to the Aervator, with the lower link arms at the same height of
the pick up attach points on Aervator.
3. Fit the right hand pin through the Aervator attach point first.
4. Continue to attach the left hand side. You may need to use level box to lift or lower link
arm to match attach point.
3 sets of holes allow the correct position to get the lift arms to suit the working conditions.
5. Connect the top link and adjust so machine is level.
Readjust if necessary when the machine is at working depth to keep frame level.
6. Tighten side sway chains on lower links to centralize and hold implement firm.
7. Lift Aervator off the ground with hydraulics.
Raise jack stands to top hole for transport and working, or remove altogether if so desired.
REGULAR MAINTENANCE
Bearings
• Grease bearings sparingly so as not to expand the metal seals. One or two pumps every 10
working hours.
Gang bolts
• Check regularly for tightness, particularly after changing settings.
Tine bolts
• After inital working period of 2 - 5 hours, re-tighten all tine bolts.
Note: Use 3/4” or 19mm ring or socket spanner on bolt head to tighten NOT on the nut.
These are special flange nuts with a serrated grip to bite into the metal and stop nut
turning.
