The big idea of the sermon ought to match closely with the big idea of the text. Steven Matthewson, in his book The Art of Preaching Old Testament Narrative, counsels a progression in thinking about the big idea, beginning with the exegetical idea, building toward a theological idea, and ultimately a preaching or homiletic idea.
Loader (equipment) - Description. 1  A loader is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted square wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground.
When the grain tank is full, a tractor with a trailer on the back pulls alongside the combine. The grain is carried up from the tank by an elevator and shoots out of a side pipe (sometimes called the unloader) into the trailer. The unwanted straw chaff tumbles from the back of the machine.
