A raking implement has at least one, preferably two, rotating rake wheels which are driven via a power takeoff to rotate about upwardly extending axes. Each rake wheel has radially extending arms, the ends of which have tines on supports pivotally connected to the arms. The tines are pivoted to move from one working position to another or a transport position in response to the torque of the driving connection so that one or more working positions can be achieved automatically during operation. The driving connection includes a geared hub connected through a coupling or directly to the tine supports and the tine supports can be movably associated or linked to the radial arms to rotate same after the tines and supports have been pivoted to another position. One or more stops and other adjusting means are employed to arrange and/or limit the positions of the tines and supports relative to the remainder of the rake wheel. |
