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
