ABSTRACT:
A tine holder for turf aerating equipment includes a horizontal tine arm having a plurality of spaced apertures therein corresponding to mounting positions of the coring tines. The hollow tines are outwardly tapered at their upper ends and the apertures in the tine arm are of a diameter equal to the inner diameter of the upper ends of the tines. A tine holding bar disposed beneath the tine arm is provided with tapered apertures aligned with the apertures in the tine arm. The taper of the bar apertures corresponds to the taper of the tine upper end and permits the seating of the coring tines in the apertures with a small portion of each tine extending thereabove. A plurality of bolts passing through aligned bolt holes in the tine arm and tine holding bar permit a clamping of the tines against the tine arm in alignment with the tine arm apertures.
