Wox Agri Services has developed an aerator toolbar to sit between the tractor and Guttler Green Master which it imports from Austria. The stars for the  Aermaster aerator are sourced from American maker Genesis Tillage. The Gen Till stars have a maximum working depth of up to 20cm.

The angle of the blades can be altered in 2° increments to increase their tilling effect.  Price for the Aermaster is £7,600.
