Abstract
Disclosed is a method of spreading aggregate. In the method, an aggregate spreading device is attached to a host machine. The device includes a support frame, a hopper disposed on the support frame, a conveyor system disposed below the hopper, and a spreader system. The spreader system is actuated from a storage position to a deployed position, and a vertical position and a slope of the spreader system are adjusted relative to a grade line. The aggregate spreading device is pushed using the host machine. Aggregate is loaded into the hopper of the aggregate spreading device, and the aggregate is directed onto the conveyor system. The aggregate is conveyed through an exit opening in a sidewall of the hopper to the spreader system. The aggregate is distributed using the spreader system.
