Aerator [2] 
A make of a tractor or power unit pulled (but not PTO operated) metal-pronged double-roller aerator for decompacting synthetic surfaces. The rollers are connected by a chain and this helps the tines pry open the compacted infill without the severity of action that would occur from a mechanised or PTO driven roller aerator. There are 3 models, each with an operating depth of up to 35mm:
AR100: operating width of 1m; weight of 200kg; with a power need of >10hp.
AR150: operating width of 1.5m; weight of 450kg; with a power need of >20hp.
AR200: operating width of 2m; weight of 530kg; with a

Aercore
A range of pedestrian operated and mounted aerators which are manufactured by John Deere. There are four models:
Aerdrain Fork
A land handled rectangular framed hand fork with interchangeable tines: solid, hollow, taper slitting, and longer solid drainage tines. It is manufactured by SISIS.
Aero-Quick
An aeration unit, with a working width of 1.5m and weighing 240kg and being attached by a 3-point linkage. Interchangeable tines as well as other attachments creates a multi-purpose unit. Slit tines variations have working depths from 125mm to 215mm, hollow corers, a disc slitter attachment, as well as a combination rear roller, rake and brush attachment. It is manufactured by GreenTek.
Aeromain
A make of heavy-duty spiker attachment for a tractor or power unit such as the Auto-trac tractor; It was manufactured by SISIS.
Air2G2 324
A pedestrian operated air injection machine, with three probes which inject compressed air into the ground. It has a working width of 1.8m, a working depth from 15cm to 30cm depending upon the tines used and a weight of about 450kg. It has the capacity to inject 40 litres of air into each m2 of ground, helping to relieve soil compaction and improve drainage rates. Surface disturbance should not occur if operated correctly. It is manufactured by GT AirInject, USA.
Air2hp
An extension compressed air hand probe (hp). It is suitable for use in confined spaces, small areas, areas around trees, and areas where the Air2G2 cannot reach, such as golf bunkers. An external air compressor is also required to which it is attached, and the probe can influence an area with a diameter of up to 0.9m and to a depth of up to 1-metre. It is manufactured by GT AirInject, USA.
Airter Compact 26190
A tractor pto operated aerator, requiring a minimum of 70hp, which injects compressed air into the soil profile via hollowed tine nozzles (injection lances). The unit is 2m wide and has 26 injectors. It is manufactured by Novokraft AG.
Airter Light 1460
A tractor pto operated aerator, requiring a minimum of 30hp, which injects compressed air into the soil profile via hollowed tine nozzles (injection lances).
Airter Neo 12140
A tractor pto operated aerator, requiring a minimum of 35 hp, which injects compressed air into the soil profile via hollowed tine nozzles (injection lances).
