Abstract
An aggregate spreading device includes a hopper, a conveyor system disposed below the hopper, and a spreader system extending from at least one side of the aggregate spreading device and configured to receive aggregate from the conveyor system. The spreader system includes a vertical support coupled to a frame of the aggregate spreading device, a first wall extending from a first end attached to the vertical support, and a second wall extending from a second end of the first wall. A lift actuator is configured to adjust the vertical placement of the spreader system and causing the first and second walls to move vertically.
