Operator's Manual

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 the 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 that 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 the
recommended gear settings and PTO drive speeds and
become thoroughly familiar with machine’s 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 promotes 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.

To avoid personal injury, never leave the tractor seat
without first setting the parking brake and
disengaging the PTO drive. Never perform aerator
repairs without lowering the aerator onto the
castor/safety stand. Be sure all safety devices are
secured in proper place before resuming operation.
