Tilther

This clever tool–conceptualized by Eliot Coleman- is a lightweight battery-powered tiller designed to work the top inch of your bed.

The cultivator makes it possible to mix in compost and refine the soil all while creating a perfect tilth for direct seeding or transplanting. Although it's not powerful enough to be used in our whole market garden, we rely on it in our greenhouses where a walking tractor doesn't maneuver easily. We recommend getting one or two18V batteries when purchasing your drill, as they run out of juice after 2 or 3-100' beds. Also,  keep in mind that this tool is not meant for working out rough soil, but rather for nicely finishing off seedbeds. Sold at www.johnnyseeds.com.

DeWalt has a new Flex Volt system whereby they now sell 20V batteries that have 3 times the power. I recommend using the Tilther with those.  Here is a link to buy just the battery. They can go on any 20V charger.
