ABSTRACT:
A turf aerator is provided with a pair of drive wheels rotatably mounted on a drive shaft supported in a main frame of the aerator. Each drive wheel is provided with a radially extending flange and a pawl is pivotally mounted on each flange. A pair of sprockets are secured to the shaft for rotation therewith and disposed in engagement with a respective pawl. A drive sprocket is mounted for rotation with the shaft and is operatively connected to the shaft of an aerator assembly and a motor driven shaft by means of a chain interconnecting sprockets on each shaft. The pawls are arranged relative to the sprockets to positively drive the drive wheels in a forward direction while permitting one pawl to ratchet relative to the sprocket in engagement therewith and permitting rotation of the drive shaft in an opposite direction without imparting a drive to said wheels.
