Promote a Healthier, Greener Lawn

The Allett UCScarifier Cartridge is Allett’s most popular cultivation tool, specifically engineered to maintain the health and appearance of your lawn. Its primary function is to remove thatch, surface debris, and dead moss, which can stifle grass growth. By clearing this layer, the cartridge allows essential air and water to penetrate the soil surface, enabling nutrients to reach the grass roots with ease. This process helps to keep your lawn surface healthy and free from disease.

Gentle, Effective, and Versatile

Featuring rotating spring tines, the scarifier’s design is both effective and gentle on the lawn. It efficiently pulls out dead grass and moss while also lifting lateral growth, preparing the turf for a cleaner, more uniform mow. The spring tines allow for safe cultivation even where tree roots may be close to the surface, making it an ideal choice for all types of gardens. Allett recommends using the scarifier once a month during the mowing season to manage thatch levels effectively.

This cartridge is particularly suitable for beginners in turf cultivation, as its gentle action is unlikely to cause damage even if set too deeply, yet it delivers excellent results with regular use. Beyond dethatching, it’s also a useful tool for collecting leaves, pine needles, and even pine cones during the autumn. This cartridge is designed for use with the Allett Stirling mower and is part of the innovative Ultra-Change cartridge system (Int Pat App WO 2023/079275), offering a cultivation depth of up to -10mm.
