I have been thinking, well, if I can use a sprinkler, could there be an automatic crop picker upper? I would be really grateful if any of you could do this .
Not exactly -auto- but there is a mod that allows you to harvest with your sythe. Which is simply amazing in how much time/effort it saves.
P sure there's a smapi auto farm mod, i dunno if that's what you're looking for but it shouldn't be too far back on the mods page, keep an eye out
