An applicator mechanism for applying a layer of aggregate material on a ground surface comprising an adjustable bracket for mounting the applicator mechanism to a carrying device, a hopper attached to the mounting bracket having a first opening for receiving a supply of aggregate materials said hopper having a second opening for dispensing the aggregate material onto the ground surface, a first shaft attached to the hopper and in communication with the second opening having projections for spreading the aggregate material onto the ground surface through the second opening, a mechanism for driving the first shaft, a second shaft having at least one structure for interacting with the projections in order to control the size or amount of aggregate material exiting the hopper through use of a spring force that adjusts the tension applied to the paddle by way of a handle used to rotate the second shaft, and a mechanism for holding the tension handle in one of several predetermined positions.
