The coring head of a ProCore SR75 deep tine aerator
consists of the aerator frame, a coring crankshaft as-
sembly, tine holders and aerating tines. The rotating
crankshaft assembly operates six (6) connecting rods
with linkage arm assemblies to provide effective tine
motion for deep turf aeration. The aerator frame pivots
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.
The coring crankshaft is composed of multiple crank-
arms, bearings, bearing housings and crank pins. The
crankshaft assembly is designed and assembled to en-
sure minimal vibration during aerator operation.
A variety of tines and tine heads are available for use on
ProCore SR Series aerators. Refer to the Operator’s
Manual for available options.
