The S40C has large wheels for great traction and a comfortable padded handlebar which folds for transportation.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.
