Tiller
A tiller for cultivating soil has a power source and a tilling shaft mounted for undergoing rotation by a driving force supplied from the power source. The tilling shaft has a hollow outer shaft and an inner shaft extending through the outer shaft. The inner shaft has a variable rotating speed and/or direction of rotation relative to the outer shaft. A power transmission mechanism transmits a driving force from the power source to the tilling shaft. The power transmission mechanism has a first power transmission system for transmitting the driving force from the power source to the outer shaft and a second power transmission system transmitting the driving force from the power source to the inner shaft. The second power transmission system has a hydrostatic transmission comprised of a hydraulic pump and a hydraulic motor for effecting a stepless change of the rotating speed of the inner shaft as well as a selective change of its direction of rotation. Tilling claws are disposed on the tilling shaft for tilling soil.
