Operation

Note:
Determine the left and right sides of the
machine from the normal operating position.

Before Operation Safety

•
Never allow children or untrained people to
operate or service the machine. Local regulations
may restrict the age of the operator. The owner
is responsible for training all operators and
mechanics.
•
Become familiar with the safe operation of the
equipment, operator controls, and safety signs.
•
Know how to stop the machine and shut off the
engine quickly.
•
Check that operator-presence controls, safety
switches, and shields are attached and functioning
properly. Do not operate the machine unless they
are functioning properly.
•
Before operating, always inspect the machine to
ensure that the tines are in good working condition.
Replace worn or damaged tines.
•
Inspect the area where you will use the machine
and remove all objects that the machine could
strike.
•
Locate and mark all electrical or communication
lines, irrigation components, and other obstructions
in the area to be aerated. Remove the hazards, if
possible, or plan how to avoid them.
•
Ensure that your tractor is suitable for use with an
implement of this weight by checking with your
tractor supplier or manufacturer.
•
Shut off the engine and wait for all moving parts
to stop before making any adjustments to the
machine.
OutCross Traction Unit
Controls
Refer to the OutCross traction unit Operator's Manual
for information on controls and operation, as well as
additional information on setting up the aerator.

Tractor Controls

Become familiar with operating the following tractor
controls before you operate the aerator:
•
PTO engagement
•
Engine/PTO speed
•
3-point hitch (raise/lower)
•
Auxiliary valve operation
•
Clutch
•
Throttle
•
Gear selection
•
Parking brake
Important:
Refer to the tractor operator's
manual for operating instructions.

Principles of Operation

The 3-point hitch linkage/hydraulic top link on the
tractor lifts the aerator for transport and lowers it for
operation.
The power takeoff (PTO) power is transmitted
via shafts, gearbox, and O-ring drive chains to a
crankshaft, which drives 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 penetration is determined by
extending the hydraulic top link or setting the fixed top
link to the desired position.
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. Changing the engine speed does not change
the hole spacing.

Tractor PTO Speed

The aerator is designed to operate with a PTO speed
of up to 460 rpm depending on the size/weight of the
tines. Most tractors indicate a 540 PTO rpm position
on the rev counters. Since the engine and PTO
speeds are directly proportional, you can determine
the engine speed required for a 400 rpm PTO by
calculating as follows:
(Engine rpm at 540 PTO speed) x (400÷540) = required engine
rpm
For example, if the engine rpm were 2,700 for a PTO
speed of 540 rpm, you would get the following:
2,700 x (400÷540) = 2,000 rpm
In this example, running your tractor at 2,000 rpm now
provides you with a 400 rpm PTO speed.
If your tractor indicates some other engine rpm at 540
PTO rpm, substitute that number for the 2,700 that
was used above.
Note:
The recommended PTO speed for 10-inch
tines and shorter is 460 rpm and 425 rpm for tines
longer than 10 inches.
