1. A sand spreader comprising:

  • a frame;

    ground wheels coupled to and supporting the frame for movement over the ground in use;

    a sand hopper mounted on the frame and having an opening at its lower end through which sand can be dispensed;

    a rotary auger mounted in the hopper and positioned in said opening therein for controlling the flow of sand from the hopper in use; and

    ,a driving wheel which is drivably coupled with the auger;

    a slide supporting the driving wheel for movement between an operative position in which the wheel is in peripheral engagement with one of the ground wheels supporting the frame of the spreader, whereby rotation of that ground wheel as the spreader moves over the ground in use drives the auger by way of the driving wheel, and an inoperative position in which the driving wheel is clear of the relevant ground wheel;

    a lever for moving the slide between a first position in which the driving wheel is in its said operative position and a second position in which the driving wheel is in its said inoperative position; and

    ,an over-centre linkage coupling the lever to the slide, said linkage being adapted to lock the slide in said first position when the lever is moved in the appropriate direction.
