A tiller may include an engine, a mobility assembly and a rotating assembly. The mobility assembly may be operably coupled to the engine to provide mobility of the tiller responsive to operation of the engine. The rotating assembly may be selectively coupled to the engine to provide rotation of the rotating assembly. The rotating assembly may include a rotatable shaft configured to turn when the rotation assembly is operably coupled to the engine, and one or more sets of tines disposed on respective tine assemblies. Each of the tine assemblies may include a hollow shaft for receiving the rotatable shaft. The one or more sets of tines may extend radially outward from the respective tine assemblies.
