The GH-4004 Aervator is a high utility farm implement that relieves compaction, aerates, cultivates and renovates. It can function as a rotary hoe, a disc, a roller and a harrow and increases the effectiveness of water and fertiliser.

Product Features

Aerate, Renovate and Maintain 00 Neutral Setting
The axle is straight
This is used when the soil structure is very friable.
The tines will usually penetrate their full depth.
This setting is usually used to maintain the soil structure, possibly once a year in a maintenance program.

Aerate and Renovate 2.50 Setting
The axle has 2.5 degrees of angle
This is ideal for your first use of the aervator.
If your ground is hard the tines may not penetrate very far, maybe only 25-50 mm.
Dont worry, this is normal. Aeration is not a quick fix.

Aerate and Renovate 50 Setting
The axle has 5 degrees of angle
Use this setting for subsequent uses of the aervator.
With each pass you should change the direction of travel.
Across then diagonally is ideal.

Cultivate and Renovate 7.50 Setting
The axle has 7.5 degrees of angle
On this setting the aervator starts to get aggressive.
You may require additional weight or ballast to achieve maximum depth.
This setting is best used after previous passes and will fracture any compaction layer.

If used on extremely hard ground the tines will probably not penetrate very far.

Cultivate 100 Setting
The axle has 10 degrees of angle
On this setting the aervator is very aggressive.
Again use weight.
This setting is best used after previous passes and will fracture any compaction layer.
If used on hard ground the tines will probably not penetrate very far.

Equipment Options

Aeration requires multiple uses of the aervator to achieve results.
Depending on your soil structure, this could take 12-24 months.
The ideal time to use is autumn and spring depending on your rainfall.
