LawnMaster Aerator Cartridge for Healthier Soil and Stronger Lawn Growth Unlock the full potential of your lawn with the Cox LawnMaster Aerator – the perfect addition to your Cox LawnMaster system. Engineered for Australian conditions, this high-performance aerator transforms compacted soil into fertile ground, allowing water, nutrients, and oxygen to penetrate deep into the roots for a healthier, greener lawn. Fits current Cox LawnMaster Cylinder Mowers. Available in both 17" & 20" Cartridges. The COX LawnMaster Aerator attaches to current LawnMaster cylinder mowers via the cassette system, adding soil aeration to the machine's existing capability. Available in 17" and 20" sizes to match the mower. Compacted soil is one of the most common causes of underperforming lawns in Australia. When soil particles are compressed - by foot traffic, machinery, or simply heavy clay content - water and nutrients struggle to penetrate to the root zone. The aerator breaks up compaction by mechanically perforating the soil surface, allowing moisture, oxygen and fertiliser to reach where they're needed. Regular aeration improves drainage, encourages deeper root development and helps lawns recover from summer stress or heavy use. It is most effective when carried out in spring or early autumn, and works across the range of turf varieties grown in Australian conditions. Designed for users who want to manage soil health as part of a structured maintenance programme, rather than addressing compaction after visible decline has already set in.
