The support wheels and drag stake of a walk-behind rotary tiller are connected to the main frame of the tiller at a location rearwardly of the tiller tines through means of a mounting bracket, which is mounted for pivotal movement between and to be releasably secured in a first position, wherein the wheels are disposed in a downward position relative to the tiller frame for transport while the drag stake is in an inactive elevated position, and a second position, wherein the drag stake is disposed for retarding the forward progress of the tiller while the wheels are in an elevated position for contacting the ground only after the tines have reached the desired tilling depth.
