We've been using the Greenworks rechargeable tiller with 40-volt, 4 amp-hour batteries for about 4 years. We have dense clay soil that sometimes gets crusty or clumpy, depending on the weather. Our beds are 4-by-20 foot size, and when we just need to transplant we simply fork the beds deeply and rake them out more or less smooth. But for seeding stuff, especially fine seeds like carrots, it often works out better to use the tiller, then rake it smooth and flat. We removed the wheels from our Greenworks since it's so easy to steer it by just leaning it left or right. We allow the tines to pull it forward, then pull slowly back to make it dig down, then lean it in the direction of the next pass and let it pull itself into position. It's very easy to use and gives very satisfactory results. We also have a Mantis 3-speed, 120-volt model from many years ago that got used for the same purpose but we got tired of moving cords around since that took 2 people and lots of cord for our big garden. One battery pack gives us enough juice for about 3 beds at 80 sq. ft. each. It's not good for breaking ground or incorporating unchopped organic material since the tines clog too easily. But it does work to incorporate if we use the Greenworks cordless 16" mower first to chop stuff down. For breaking sod on new ground we have an electric 30" tiller on the back of our trusty old G.E. Elec-trak 36-volt garden tractor. Two passes with that does the big jobs. We don't use it for annual "tillage" since just a long-tined garden fork does the job to deeply "fluff" our snow-compacted clay. A wheel hoe with stirrup blade finishes that job. All of our cordless stuff, the tractor, electric bikes, and our house are charged from our 4.4 KW PV system.
