This hoe turns a single crop-break into a full harvest run - it checks a 3x3x3 volume around whatever you hit for anything ripe, clears it all in one motion, and quietly restocks the field behind you.
Only crops that are fully grown (max age reached - a half-ripe wheat stalk is left alone) inside the 3x3x3 cube centered on your hit get harvested. For each one harvested, it immediately queues a replant:
After crops are handled, a second, wider 5x5x5 sweep clears anything else instantly-breakable nearby - flowers, tall grass, saplings, and other "bush-family" blocks - except anything that's a crop (those are strictly pass one's job, so a not-yet-grown wheat stalk caught in this wider net is left standing to keep growing). A few things get special treatment instead of a flat break: sugar cane is walked stalk by stalk and always leaves its base segment standing so the plant keeps growing, sweet berry bushes are harvested for their berries without the bush itself ever being destroyed, and melon/pumpkin stems are skipped entirely.
