OPERATION
In instances where sufficient root growth exists, the turf
guards may be removed to attain maximum depth
without damaging the turf guards.

Tractor Controls
It is necessary to familiarize yourself with the operation
of the following tractor controls before you are able to
operate the aerator:
 PTO Engagement
 3 Point Hitch (Raise/Lower)
 Clutch
 Throttle
 Gear Selection
NOTE: Refer to tractor operator's manual for operating
instructions.
PRINCIPLES OF OPERATION
The tractor's three point hitch linkage lifts the aerator
for transport and lowers it for operation.
The tractor's power take-off (PTO) power is
transmitted via shafts, gearbox and drive belts to a
number of crankshafts which drive the tine holding
arms into the turf surface.
As the tractor travels forward with the PTO engaged
and the machine lowered, a series of holes are created
in the turf surface.
The depth of the tine's penetration is determined by the
mounted angle of the aerator and the height of the
depth control roller.
The distance between the holes created is determined
by the tractor's gear ratio (or hydrostatic traction pedal
position) and the number of tines in each tine head.
Simply changing engine rpm does NOT change hole
spacing.
TRAINING PERIOD
Before using the aerator, find a clear area and practice
using the machine. Operate the tractor at
recommended gear settings and PTO drive speeds
and become thoroughly familiar with machine
handling. Practice stopping and starting, raising and
lowering the aerator, disengaging the PTO drive and
aligning the machine with previous passes. A practice
session assures confidence in the performance of the
Aerator and helps ensure use of proper operating
techniques wherever the machine is operated.
If there are sprinkler heads, electrical or
communication lines or other obstructions in the area
to be aerated, mark these items to assure they are not
damaged during operation.
CAUTION
To avoid personal injury, never leave the
tractor seat without first setting the park
ing brake and disengaging the PTO drive.
Never perform aerator repairs without first
lowering the aerator onto the castor/safe
ty stand. Be sure all safety devices are se
cured in proper place before resuming op
eration.
BEFORE AERATING
Inspect the area of operation for hazards that could
damage the machine and remove them, if possible, or
plan how to avoid them. Carry replacement tines and
tools to effect repairs should tines contact foreign
materials.
