Three words: Manage Thy Kingdom. This thing is the god of all things. Set it for 100% maples and 50% herbs. Collect it every week or so, sell the maples to get your money back, then you have some tree seeds (great farming exp) and herbs to help you level. All you have to do is plant trees, pay the farmer, and leave, then come back whenever. That's what I've done from 18-63 farming. :D Plus I've gotten 55-60 herblore from the herbs.
