Toro ProCore SR Series Service Manual page 43

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 SR54 and SR70 aerator
frames pivot on a single roller to allow aerating depth
control. The SR54--S and SR70--S aerators are
equipped with dual rollers.
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.
ProCore SR Series
The coring crankshaft is composed of multiple crank
arms, bearings, bearing housings and crank shafts. 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.
