What does tiller mean?
A tiller most commonly refers to the lever used to steer a boat. It is attached to the rudder, so moving the tiller changes the vessel's direction. The word can also denote a farmer or other person who tills soil, and, especially in North American English, a small powered agricultural implement used to cultivate a garden or field. These meanings are distinct but share the spelling and pronunciation /ˈtɪlər/. In nautical contexts, the tiller is valued for giving direct manual control of a vessel's steering; in figurative use, “being at the tiller” means being responsible for directing an organization, course of action, or undertaking. Although the agricultural and nautical senses have different historical developments, both remain established in modern English. The word is useful because it belongs equally to the worlds of navigation and farming.

Where does tiller come from?
The agricultural sense of tiller is an agent-noun formed from till, a verb inherited from Old English tilian, meaning “to cultivate” or “till.” The nautical sense has a separate and less certain origin and was already used in Middle English for the vessel's steering lever. The two similarly pronounced senses therefore have distinct historical developments despite sharing a modern form.

How tiller is actually used
In nautical use, the tiller is the steering lever rather than the submerged rudder itself. In agricultural contexts, especially in North American English, it denotes a compact powered cultivator. The figurative expression “at the tiller” means being in charge or having control.
