1. An aggregate spreading device configured to be reversibly attached to a host machine, the aggregate spreading device comprising:
a support frame comprising a first end and a second end;
a hopper disposed on the first end of the support frame;
a conveyor system disposed below the hopper;
a first spreader system configured to distribute aggregate received from the conveyor system;
a first lift actuator comprising a first vertical support coupled to the first spreader system and to the support frame at a first distal end of the hopper, the first lift actuator configured to raise and lower the first spreader system;
a first position actuator coupled to the first spreader system and to the support frame at a location between the first end and the second end, the first position actuator configured to transition the first spreader system between a storage position and a deployed position; and
a first slope actuator coupled to the first spreader system and to the first vertical support, the first slope actuator configured to adjust a first angle of the first spreader system relative to a grade line of ground over which the aggregate spreading device is configured to travel.
