Abstract
A tine holder for turf aerating equipment includes a horizontal tine arm having a plurality of spaced apertures therein having a diameter substantially equal to the inner diameter of the upper ends of the tines. The hollow tines are substantially cylindrical at their upper ends and abut the tine arm in alignment with the tine arm apertures. A tine holding bar disposed beneath the tine arm includes a plurality of tapered apertures aligned with the apertures in the tine arm. The tines pass through the tine holding bar apertures and are secured in position by split collets having frusto-conical exterior surfaces which seat within the tapered apertures of the tine holding bar. A plurality of bolts passing through aligned bolt holes in the tine arm and tine holding bar provide a tightening of the split collets to secure the tines in position against the tine arm.
