Abstract
A turf aerator includes a tine assembly and an input mechanism. The tine assembly includes multiple tines, a retractor plate for positioning the plurality of tines, and a linkage for selectively moving the retractor plate and the plurality of tines between an operating position and a retracted position. The input mechanism coupled to the linkage, the input mechanism operable to activate the linkage to move the retractor plate and the plurality of tines between the operating position and the retracted position.
Claims20
A turf aerator, comprising:
- a tine assembly comprising:
- a plurality of tines;
- a retractor plate for positioning the plurality of tines;
- and
- a linkage for selectively moving the retractor plate and the plurality of tines between an operating position and a retracted position;
- and
- an input mechanism coupled to the linkage, the input mechanism operable to activate the linkage to move the retractor plate and the plurality of tines between the operating position and the retracted position.

A turf aerator, comprising:
- a frame;
- a tine crank rotatably supported by the frame;
- a plurality of tines coupled to the tine crank;
- a swing arm rotatably supported by the frame;
- a retractor plate fixed to the swing arm, the tines passing through openings in the retractor plate;
- a linkage for selectively moving the retractor plate from an operating position to a retracted position, a first end of the linkage terminating at a pedal;
- a keeper bar fixed to the swing arm;
- a latch for engaging the keeper bar when the retractor plate is at the retracted position, the latch being rotatably supported by the frame;
- and
- an input for selectively rotating the latch to disengage the keeper bar, thereby allowing the retractor plate to move from the retracted position to the operating position.

A turf aerator, comprising:
- a frame;
- a tine crank rotatably supported by the frame;
- a plurality of tines coupled to the tine crank;
- a pair of swing arms rotatably supported by the frame;
- a retractor plate fixed to the pair of swing arms, the tines passing through openings in the retractor plate;
- a linkage for selectively moving the retractor plate from an operating position to a retracted position, a first end of the linkage terminating at a pedal;
- a keeper bar fixed to the pair of swing arms;
- a latch for engaging the keeper bar when the retractor plate is at the retracted position, the latch being rotatably supported by the frame;
- and
- a cable for selectively rotating the latch to disengage the keeper bar, thereby allowing the retractor plate to move from the retracted position to the operating position, the cable being operable by a release handle.
