ABSTRACT:
The invention relates to a system for motor-driven ride-on lawn mowers of the type where the cutting assembly is placed in front of the front axle, in which the front wheels are adapted as driving and braking wheels and the rear wheels as steering wheels. The new feature is that the brake mechanism acting upon the front wheels is provided with a modulation apparatus which, independently of the power exerted by the driver on the brake pedal or the like, prevents the braking power acting upon the wheels from reaching the amount where the wheels would be locked.
