Ideal for homeowners with medium to large lawns, this machine effectively removes the suffocating layer of thatch and moss, allowing vital water, air, and nutrients to reach the soil and grass roots. Powerful Engine & Dual-Purpose System At its core is a reliable 212cc Cobra 4-stroke engine, providing ample power to tackle even densely matted lawns. The S40C’s key feature is its interchangeable blade system. It includes two easily swappable cartridges to suit your lawn’s needs. The 18-bladed aeration cylinder is designed to cut into the soil, relieving compaction and improving drainage. The 24-spring tine cylinder efficiently rakes moss and thatch from the surface of the lawn, promoting better growth.

The working depth is fully adjustable between -15mm and 5mm, giving you precise control over the intensity of the treatment. For convenience, a simple transport mode lever lifts the blades or tines clear of the ground, making it easy to move across paths or patios without causing damage. The machine also features a 45-litre collection bag to gather the removed debris, folding handles for compact storage, and an engine on/off safety switch for secure operation.

Frequently Asked Questions What is the difference between scarifying and aerating with the Cobra S40C? The Cobra S40C comes with two interchangeable cartridges for these distinct tasks. Scarifying, using the 24-spring tine cylinder, is the process of raking out surface-level moss and thatch. Aerating, using the 18-blade cylinder, involves cutting into the soil to relieve compaction, which improves drainage and allows air and nutrients to reach the grass roots. Using both at different times of the year provides comprehensive lawn care. Is the Cobra S40C suitable for a large garden? Yes, with its powerful 212cc petrol engine and a 40cm (16″) working width, the Cobra S40C is well-suited for medium to large-sized lawns. Being a petrol model, it is not restricted by cable length, allowing you to cover extensive areas without interruption. How often should I scarify my lawn? For most UK lawns, scarifying is best done in the spring (April/May) or autumn (September/October) when the grass is actively growing and can recover quickly. A light scarify can be done once a year, while a lawn with heavy thatch build-up might benefit from treatment in both spring and autumn. What type of fuel and oil does the Cobra S40C use? The Cobra S40C uses a 4-stroke engine, which means you should use standard unleaded petrol (E10 is suitable). It requires separate engine oil (typically SAE30 or 10W-30) in the sump. It is crucial not to mix oil with the petrol, as this will damage the engine. Always check the user manual for specific recommendations. User Manuals / Downloads View Cobra Brochure
