Achieve a Healthier Lawn with the Allett Slitter
The Allett C-Range Slitter Cartridge is a specialist accessory designed to significantly improve the health and appearance of your lawn. This non-powered cartridge works by penetrating the soil surface, creating small slits that act as channels. These channels allow vital oxygen, water, and nutrients to bypass the surface thatch and reach the grassroots where they are needed most.
Ground-Driven, Effective Aeration
Unlike powered tools, this lawn slitter operates in direct relation to the forward movement of the mower. It is driven by ground contact, making it a simple yet highly effective way to aerate the soil. This process encourages the development of a strong, deep root system, which is the foundation for thick, thriving, and resilient grass growth.

Frequently Asked Questions
Frequently Asked Questions
What is the main purpose of the Allett C-Range Slitter Cartridge?
The primary purpose of the slitter cartridge is to aerate the lawn. It cuts thin slits into the soil surface, which helps to relieve compaction and allows oxygen, water, and nutrients to penetrate more easily to the grassroots, promoting a healthier and more robust lawn.
Is the Allett C-Range Slitter powered by the mower’s engine?
No, the Allett slitter attachment is a non-powered cartridge. It rotates as a result of direct ground contact when you push the mower forward. This simple, mechanical action is highly effective for soil aeration without requiring engine power.
How often should I use a slitter cartridge on my lawn?
The frequency of use depends on your lawn’s condition, soil type, and the time of year. Generally, slitting is beneficial during the growing seasons (spring and autumn) every 4-6 weeks as part of a comprehensive lawn care routine. It helps to keep the soil open and receptive to nutrients and moisture.

The Allett C-Range Slitter cartridge is specifically designed for Allett C-Range cylinder mowers. It is part of the interchangeable cartridge system that makes these mowers so versatile for complete lawn care.
