A horizontal extension of a tiller frame supports the engine, gear box, and tine assembly of a tiller. The tiller frame has a portion which defines the tiller handle and includes a one-piece, forked end which provides the horizontal extension and, in addition, provides a generally vertical extension which supports the tiller wheels. At its forked end the tiller frame is generally delta-shaped having a broad, web-like portion extending between and integral with the horizontal and vertical frame extensions and arranged in a vertical plane.
