Abstract:
1. A gas tiller having a travel configuration for transport over ground and a tilling configuration, the tiller comprising: a frame defining a first pivot axis and a second pivot axis substantially parallel to and spaced a distance from the first pivot axis; a motor coupled to the frame; a set of rotary tines coupled to the frame and operatively coupled to the motor; a swing arm pivotably coupled to the frame and supporting at least one wheel, the swing arm being pivotable about the first pivot axis between a first arm position, corresponding to the travel configuration and in which the wheel is in supporting engagement with the ground, and a second arm position, corresponding to the tilling configuration and in which the wheel is not in supporting engagement with the ground; and a drag stake coupled to the frame for pivoting movement about the second pivot axis between a first stake position, corresponding to the travel configuration and in which the drag stake is out of engagement with the ground, and a second stake position, corresponding to the tilling configuration and in which the drag stake is in engagement with the ground, movement of the swing arm between the first arm position and the second arm position causing movement of the drag stake between the first stake position and the second stake position.
