Air-Ject Aerator

Model: BA-4

Aeration encourages roots to grow deeper by increasing the oxygen supply to the root zone for healthy green grass. The Bannerman BA-4 Air-Ject Aerator is a commercial grade self-propelled, walk behind aerator.

The Air-Ject can now be fitted with a total of 4 different types of tines: Core, Slitter, Fracture and Spiker. Our compact size allows for easy and safe operation in confined areas, and less operator fatigue.

Our new tine reel assemblies allow for smoother operation, and more holes per square yard.  The unique front tine reel system allows for the most maneuverability and speed in the industry.  Simply tilt back and turn; no more lifting and lowering like a rear tine aerator. Ballast weight bars maintain maximum penetration in the ground.
