Understanding the Principles
of Operation
The 3-point hitch linkage of the tractor lifts the aerator for
transport and lowers it for operation.
The power take-off (PTO) power from the tractor is
transmitted via shafts, a 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 penetration depth of the tines is determined by the
height of the depth control.
The distance between the holes created is determined by
the gear ratio (or hydrostatic traction pedal position) of the
tractor and the number of tines in each tine head. Simply
changing engine rpm does not change hole spacing.
Practicing the Operating
Procedures
Important:
When connecting the PTO, ensure that the
aerator is not lifted higher than is necessary. Lifting the
machine too high will cause the PTO shaft knuckles to
break (
Figure 25 ). The PTO can operate up to an angle
of 25°, but can never exceed a 35° angle when the aerator
is at its highest position, or severe shaft damage may
occur.

Before using the aerator, find a clear area and practice
operating the tractor with the aerator attached. Operate the
tractor at recommended gear settings and PTO drive speeds
and become thoroughly familiar with the aerator/tractor
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 ensure they are not damaged during operation.
CAUTION
To avoid personal injury, never leave the tractor seat
without first disengaging the PTO drive, engaging
the parking brake and shutting off the engine.
Never perform aerator repairs without first lowering
the aerator onto the storage stand or appropriate
blocking or jacks. Ensure that all safety devices are
secured in proper place before resuming operation.
Preparing to Aerate
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 in case tines
are damaged due to contact with foreign materials.
Operating the Machine
Note:
When using needle tine heads, make sure to read
the instructions included with the kit for unique operating
procedures.
1. Lower the aerator on the 3 point linkage so that the
tines are nearly to the ground at the lowest part of their
stroke.
2. At a low tractor engine rpm, engage the power take off
(PTO) clutch to start the aerator working.
Important:
Never operate the aerator without the
tine heads installed.
3. Select a gear that gives a forward speed of approximately
1 to 4 km/h (0.6 to 2.5 mph) at the rated PTO speed
of 540 rpm (refer to the tractor operator's manual).
4. As the clutch is released and the tractor moves forward,
lower the machine fully into the turf and increase
engine speed to give a maximum of 540 rpm at the
PTO.
Important:
Never operate the tractor PTO in
excess of 540 rpm or damage to the aerator could
occur.
Note:
Make sure that the roller is on the ground.
5. Note the hole pattern. If you require greater hole
spacing, increase forward the speed of the tractor by
shifting up a gear or with a hydrostatic drive tractor,
actuate the hydrostat lever or pedal to give faster speed.
For closer hole spacing, decrease tractor forward speed.
Changing engine speed, in a particular gear, will
not change the hole pattern.
Important:
Look backward frequently to ensure
that the machine is operating properly and
alignment is maintained with previous passes.
