Abstract
A turf aerator includes a retracting tine assembly and an input mechanism. The tine assembly includes a plurality of tines, a pair of swing arms, and a linkage for selectively moving the pair of swing arms and the plurality of tines from the operating position to the retracted position. The pair of swing arms support the plurality of tines and are configured to rotate the plurality of tines between an operating position to a retracted position. The input is coupled to the linkage and the input is operable to active the linkage to move the pair of swing arms and the plurality of tines from the operating position to the retracted position.
