I found your Sun Joe 13.5 Amp Electric Tiller Demo videos on YouTube, and then found your blog from there.
I'm currently trying to expand my garden by plowing on contour. The plowing us being done by hand with shovel.
It works but uses a lot of human time and energy and I was wondering if there is a more efficient way.
I'm not opposed to using oil/gas to something more natural. Technique or technology to take either less human time, or less human labor, or both, than a shovel.
Do you have any ideas?
