General Information

Coring Head Operation

The coring head of the Greens Aerator consists of a piv-
oting coring frame, two coring crank sets, tine arms with
connecting rods to provide vertical tine motion, turf
guards, tine holders and aerating tines.
Drive for the coring head comes from the engine
mounted pulley through a 3V section drive belt that is
tensioned by a spring loaded idler pulley. The drive belt
rotates the power shaft located on the coring head which
in turn drives the coring crank sets with roller chains.
The two coring crank sets are composed of welded
sprocket and crankarm assemblies that are supported
by bearings and bearing caps. For assembly purposes,
proper crank position is identified by alignment holes
that exist in crank gears and the coring frame. Crank
sets are timed to ensure minimal machine vibration.
A variety of aerating tines and tine holders are available
for use on the Greens Aerator. Refer to the Operator's
Manual for available options.
Coring Head Lock–Up Brackets
Whenever service is to be performed on coring head
components, fully raise coring head and raise lock–up
brackets on each side of machine. Once lock–up brack -
ets are raised, lower coring head until it rests on brack -
ets (Fig. 2).
After service is completed, raise coring head and lower
lock–up brackets.

Coring Head Adjustments

See Operator's Manual for adjustment procedures for
