Greetings! We run a market farm, 1 acre, and we're in the market for a new string trimmer and a small tiller. (We use a larger walk-behind tiller for most of our land, which works great. This would be an additional tool to use for smaller areas.) We're wondering if anyone has experience with the battery-powered Ryobi string trimmer, and specifically, the tiller attachment that can be used with it. It looks like it could be a good solution for us, and we like the idea of buying only one tool with multiple attachments. However, we're concerned about whether it will be powerful and durable enough for farm work. Thank you!
