All our 14'' and 17'' cartridges fit into our Classic Petrol mowers. This spring-tine cartridge is very versatile and helps keep the lawn canopy clean by gently removing thatch and moss. It is also great at collecting leaves, pine needles and even acorns to help with autumnal lawn health and lawn presentation.
You don't have the same precision using the cartridges as you would with the Kensington or Liberty 43 though as the Classic has pre-set heights of cut only.
This video explains the difference.
