A towed implement for operation on roads and oft road. Known towed implements in agriculture have, e.g., pressurized air brakes which enable th em to be effectively braked, particularly during travel on roads, without causing skidding of the towing tractor. However when such brakes are used off road it is regarded as a drawback that, e.g., they cause damage to turf. As a solution to the problem of overly vigorous braking during off road operation, a towed implement is proposed wherein the braking force is controlled so as to be of a greater magnitude during on-roa d operation than it is for off road operation. For this purpose, a sensor is provided fo r sensing the operating condition of a component which provides a signal indicative of whether or not the implement is operating off road or on-road, with the signal being used t o control the amount of force used for braking the implement.
