The Allett UC Verticut Cartridge is a highly effective and popular accessory within the Allett lawn care range. Engineered with thin, closely spaced blades, it excels at lifting lateral growth and removing moss, which in turn encourages tillering and fresh, vigorous growth. It is an indispensable tool for picking up flat-lying grasses that the main cutting cylinder might otherwise miss, ensuring a perfectly uniform finish.
Advanced Lawn Health and Thatch Control
Verticutting is a key practice for maintaining optimal lawn health and can be performed more frequently than intensive scarifying. This cartridge is the perfect solution for managing thatch levels throughout the growing season. While a small amount of thatch is beneficial, any layer exceeding half an inch can hinder healthy growth by preventing water and nutrients from reaching the soil. The verticut cartridge typically removes twice as much material as a scarifier, making it a powerful tool for lawn maintenance.
The primary aims of verticutting include:
- Pruning grasses to improve tillering and stolon formation, which significantly increases turf density.
- Controlling thatch by removing dead and dying grass plants from above the thatch layer before they can contribute to its build-up.
- Producing an upright grass sward prior to mowing, leading to a cleaner and more consistent cut.
- Providing a chemical-free method of controlling weeds and unwanted weed grasses.
- Removing annual meadow grass seed heads and promoting the growth of finer grasses like bent and fescue.
Effortless Integration and Use
This cartridge is designed for Allett’s homeowner range of cylinder mowers that feature the innovative Ultra-Change (UC) interchangeable cartridge system. It can be swapped with the main cutting cylinder in just a couple of minutes, without the need for tools. For best results, the verticut cartridge can be used approximately every two weeks from April to September. It is advisable to start on a higher setting (e.g., setting four) and gradually lower it. Crucially, the blades should not penetrate the soil, as this can cause damage; they are designed to operate within and just above the thatch layer.

Frequently Asked Questions
Frequently Asked Questions
What is the difference between verticutting and scarifying?
Verticutting is a less aggressive process than scarifying. Its thin blades are designed to lift lateral grasses and remove surface thatch and moss, effectively ‘pruning’ the lawn to encourage denser growth. Scarifying is a more intensive process that cuts deeper into the thatch layer and soil to remove a much larger volume of material, and is typically done less frequently. The verticut cartridge can be used regularly (e.g., every two weeks) to maintain lawn health between annual scarifications.
How often should I use the Allett Verticut cartridge?
For best results, the verticut cartridge can be used every two weeks or so during the main growing season, which is typically from April to September. This regular use helps to keep thatch levels under control and promotes a healthy, upright grass sward.
Which Allett mower is this cartridge compatible with?
The Allett UC Verticut Cartridge is specifically designed for use with the Allett Stirling cylinder mower. It utilises Allett’s ‘Ultra-Change’ system for quick and easy swapping of cartridges. Make sure to choose the correct size for your mower.
How deep should the verticut blades be set?
The blades should be set high enough so they do not penetrate the soil. The goal is for the tips of the blades to tease and lift the material in the thatch layer. It is recommended to start on a high setting, such as setting four, and gradually lower it until you can see it is effectively removing debris without digging into the ground, which could damage the blades and your lawn.
