The Kensington 20B 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 stainless steel front roller and heavy steel rear roller help produce those beautiful, classic stripes that are the hallmark of an Allett lawn.

Equipped with a six-bladed precision cutting cylinder delivering 79 cuts per metre, the Allett Kensington 20B is powered by a 127cc XR550 Briggs + Stratton petrol engine and has a 20”(51cm) cut. It also features an infinitely variable micro cutting height adjustment from ¼ to 1 ¼ inch (6mm-32mm).

For enhanced lawn care, a range of optional additional cartridges can be fitted in place of the standard cutting unit. These include; the 10 bladed cutting cylinder, Aerator, Lawn Brush, Dethatcher, Scarifier and a Verticut cartridge.
