A lawn mower with an integral chipper or shredder, comprising: a deck, having a general overall volute shape with a rearwards-facing funnel which runs along one side of said deck, expanding towards and exiting at the rear of said deck, the exit of said funnel forming an exit aperture at the rear of said deck, a skirt arranged around at least part of the perimeter of said deck, said deck and said skirt enclosing a cutting space under said deck, a handle connected to the rear of said deck, a front wheel set and a rear wheel set located at the front and the rear of said deck respectively, a motor attached to the outside top of said deck, said motor having a drive shaft extending downwards from said motor through said deck, the lower part of said drive shaft located substantially at the centre of said cutting space, at least one grass cutting blade or blades, at least one chipper or shredder blade or blades, said at least one grass cutting blade and said at least one chipper or shredder blade connected to said drive shaft within said cutting space so that in use said drive shaft causes said at least one grass cutting blade to rotate in a substantially horizontal grass cutting plane and said at least one chipper or shredder blade to rotate in a substantially horizontal chipping plane, said chipper or shredder blade located above said grass cutting blade so that said chipping plane is above said grass cutting plane in said cutting space, wherein said mower has a power take-off mechanism connecting to said rear wheel set and said motor and adapted to drive said rear wheel set in use, characterised in that a chipper or shredder tube having an upper end and a lower end, said lower end opening into said cutting space above and within a perimeter of a chipper or shredder cutting disc formed by rotation of said at least one chipper or shredder blade in use, and wherein said power take-off mechanism comprises at least a gearbox, an axle, a pulley wheel and a drive belt, said axle connected to said gearbox and also connected to said rear wheel set, said pulley wheel connected to said gearbox so that rotation of said pulley wheel drives said gearbox, said gearbox adapted to turn said axle when driven by said pulley wheel so that said rear wheel set is driven in at least a forward direction, said drive belt running in a continuous loop between said motor drive shaft and said pulley wheel, said drive belt connected to said drive shaft in such a way that said drive shaft drives said drive belt, said power take off mechanism and said chipper tube arranged so that said chipper tube passes through said continuous loop of said drive belt, and wherein said gearbox, said pulley wheel and said drive belt are connected to said mower in such a manner that said gearbox is below said pulley wheel and said drive belt in use. a deck, having a general overall volute shape with a rearwards-facing funnel which runs along one side of said deck, expanding
