The Allett 14 inch aerator quick change cartridge is part of the Allett complete lawncare system. The aerator cartridge is suitable for using with the Allett Kensington 14K cylinder lawn mower. By aerating your lawn you produce slits in the ground which provide extra movement and space for extra hydration and nutrients to be absorbed. The added nutrients help the lawn to grow thicker and greener for a healthier appearance all year round.
