US Patent 7874374 Turf aerator tine

A tine for a turf aerator comprises a hollow, generally cylindrical tine having a lower section that first contacts the ground as the tine is driven into the ground with the lower section having an open bottom mouth. The tine includes an aeration core exit. A core comprising a splitting or dividing wall is fixedly carried within the hollow tine to split or divide the aeration core into at least two sub-cores or pieces thereof, which are subsequently ejected from the tine through the exit. These two sub-cores dry more quickly than the single larger aeration core that would have been formed and ejected had the core splitter been absent.
