Abstract:
An applicator mechanism for applying a layer of aggregate material on a ground surface comprising:a. a bracket for mounting the applicator mechanism to a carrying device; b. 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; c. a spreading shaft attached to the hopper and in communication with the second opening having projections attached to said spreading shaft for spreading the aggregate material onto the ground surface through the second opening; and d. a paddle shaft having at least one member in contact with the projections so as to apply a varying force against said projections in order to control the size or amount of aggregate material exiting the hopper through use of a tensioning mechanism that adjusts the force applied to the projections by said at least one member.
