According to the invention, there is provided a grass treatment apparatus (an aeration device), including a support, a ground treatment implement mounted on the support, means for sensing the operating position of the ground treatment implement relative to the ground in use, means for adjusting the ground treatment implement in response to the sensed position of the ground treatment implement to maintain the ground treatment implement at a desired operating position following the contour of the ground, over which the ground treatment implement travels in use. Alternatively, the invention is an aeration device having a frame that supports reciprocating tines, and a frame orientation control for an aeration device, and includes a means for sensing or tracking the ground that is operatively connected to a means to control a ram and the associated ram.
An aeration device comprising a frame supporting a series of reciprocating tine heads and a drive means to drive said reciprocating tine heads, where said frame is connectable to a pulling vehicle, and a frame orientation device comprising a means for sensing the ground, said means for sensing positioned on said aeration device, said means for sensing the ground operatively connected to a means to control the orientation of a frame.
