The FSA 30 battery-powered grass trimmer is an extremely light grass trimmer that is particularly suitable for mowing jobs in small yards, maintaining lawn edges and clearing around trees, under shrubs or along garden walls and stairs. It’s part of the AS System and powered by a removable lithium-ion battery that can also be used in other tools in the range, such as the HSA 26 shrub shears or HSA 30 hedge trimmer.
