Abstract

A garden shredder to shred garden material comprising a feeder for receiving said garden material, one or more blades for shredding said garden material received by said feeder, a series-type electric motor connected to move said one or more blades, and an electronic controller for controlling the electric motor, the electronic controller comprising an electronic circuit including means to sense the speed of rotation of the motor and means to control the speed of the motor to reduce the increase of the speed of rotation of the motor when the load applied to the motor by said one or more blades is reduced or removed In this way, when there is no or only a small amount of garden material fed to the blades, the increase of the speed of rotation of the blades and hence the noise generated is reduced.
