I have been looking for a small powered rotary hoe for years in Thailand with no success for home use
I recently found and ordered one on Lazada, Look for a power tiller, only one comes up priced at about 23,000 baht, click on it and scroll down to the bottom of the page, there are pictures of smaller models, i have ordered one with a 30cm/12inch cut and it costs less than 6000 baht
