The coring head of a ProCore SR deep tine aerator con-
sists of the aerator frame, a coring crankshaft assembly,
tine holders and aerating tines. The rotating crankshaft
assembly operates a number of connecting rods with
linkage arm assemblies to provide effective tine motion
for deep turf aeration. The SR48 and SR72 aerator
frames pivot on a single roller to allow aerating depth
control.
Drive for the coring head is provided by the towing trac-
tor PTO output shaft. A gearbox on the ProCore aerator
is rotated by a driveshaft connected to the tractor PTO
shaft. The aerator gearbox provides rotation for the cor-
ing head crankshaft assembly with two (2) drive chains.
The drive chains are each tensioned by an adjustable
idler sprocket.
