The Kensington 14B has a number of special features giving it an unbeatable cutting performance. The spring tine comb attached to the Kensington lifts the grass prior to cutting to ensure an even cut, and a zinc plated steel front roller and heavy steel rear roller help produce those beautiful, classic stripes that are the hallmark of an Allett lawn.
