Lesson 2/Learning Event 2
Aggregate Spreaders
Aggregate spreaders include such items as the standard hopper-type spreader, the nonstandard
whirl type spreaders, and the self-propelled spreader.

The drag boom is usually available through normal supply channels, but may be constructed in
the field. Shop brooms and 3- by 6-inch timbers are the best expedient construction materials.
