A walk-behind tiller has a body and a pair of wheels mounted on the body for undergoing rotation to cause the walk-behind tiller to undergo travelling along a ground surface. A tilling device is mounted on the body for undergoing a first movement operation in which the tilling device travels along the ground surface while the tilling device is disposed in spaced-apart relation to the ground surface, a second movement operation in which the tilling device tills the ground, and a third movement operation in which the tilling device is maintained generally horizontal to the ground surface. A handle has proximal portions, a pair of grip portions connected to the proximal portions and configured to be gripped by an operator to maintain the tilling device generally parallel to the ground surface during the third movement operation, a pair of rising portions connected to the grip portions and configured to be tilted by the operator during the second movement operation to cause the tilling device to till the ground, and a cross portion disposed between the rising portions and configured to be gripped and pressed by an operator to produce a force tending to move the tilling device about the rotational axis to maintain the tilling device in spaced-apart relation to the ground surface.
