New for 2019, the Cobra S40C is a 40cm / 16" petrol scarifier and aerator in one. The modular blade system consists of a 16 spring tine cartridge for scarifying and a 17-blade cartridge for aerating the soil.


  • 212cc 4 stroke engine
  • Ergonomic and comfortable design
  • Padded and folding handlebar
  • 40cm / 16” working width
  • Scarifying cartridge with 16 spring tines
  • Aerating cartridge with 17 bladed cartridge
  • Easily switch between cartridges
  • 45 litre collector
  • Dial adjusted working height

The S40C is powered by a 212cc 4 stroke engine and the large wheels give excellent traction across long grass and uneven ground. A simple dial changes the height and depth of the cartridges with an operating range of -15mm up to +5mm.

Scarifying works by removing moss, weeds and thatch and allowing sunlight to reach the grass roots and preparing the lawn for grass seed. The cartridge rotates and the 16 sprung tines effectively rip the unwanted organic matter and collects it into the 45-litre bag for emptying. Scarifying is best suited for the spring and autumn months.

Aerating is an efficient way of getting moisture and oxygen deep into the soil and encouraging drainage when conditions are wet. The aerator cartridge rotates and claws at the surface removing any moss or detritus left after scarifying and collects it into the bag. The 17 robust blades can also be set to slice into the soil for increased aeration. This process is recommended regularly for the entire growing season and as and when required.
