Lowering the feed dogs hands control of the fabric to you. Normally they grip and advance the fabric a fixed distance per stitch, which is what makes a straight seam straight. Dropped, they release it entirely.
What that is for.
Free-motion quilting — you move the quilt under the needle and draw with stitches. The machine stitches; you decide where.
Darning and mending — building up stitching across a hole in any direction.
Free-motion embroidery — thread painting on an ordinary machine.
Sewing on buttons, where the fabric must not move at all.
What else has to change. Fit a darning or free-motion foot, which hops rather than pressing. Stitch length becomes irrelevant — the length is however fast you move your hands relative to the needle. And use a hoop or a well-basted sandwich, because unsupported fabric flaps and skips stitches.
If your machine has no drop-feed lever, most come with a cover plate that sits over the feed dogs and does the same job.
Remember to raise them again. A machine that suddenly will not feed is usually a machine left in drop-feed.
Questions people actually ask
My stitches are uneven in free motion.
That is hand speed against machine speed. Run the machine faster than feels natural and move your hands slowly and steadily — most people do the opposite.
Do I need a special foot?
Yes. A standard foot holds the fabric down continuously and you cannot move it. A darning foot lifts between stitches.
