Abstract: A braking system for a rotary mower includes a brake element which is secured to an impeller and is urged by a spring normally into braking engagement with a fixed brake friction member. On start-up of a motor of the mower, rotation of the impeller causes axial movement of the brake element against the spring and out of braking engagement. Movement of the brake element may be assisted by mechanical means, for example by a multiple ball and ramp system or arrangement. In this embodiment, four equally spaced balls are normally located in ramped recesses formed in an upper face of an adaptor element, such that on start-up of the motor, the balls ramp up at least partially out of the recesses, and assist in urging a braking element and a friction element out of braking engagement with one another. This assist stops when the motor is turned off, the balls now moving back into their respective lowest positions in the recesses formed in the upper face of the adaptor element.
