Operating Instructions

STARTING THE MACHINE

Refer to the appropriate Tractor Owner’s Manual for

tractor starting and operating procedures.

ENGAGING THE AERATOR

Refer to the appropriate Tractor Owner’s Manual for

tractor starting and operating procedures.

1.

Release the tines into the operating position by

pushing on the foot trigger and using the lift

lever to lower the tines.

2.

Set the engine throttle at full speed.

3.

Begin driving the tractor forward slowly.

4.

Pull the PTO clutch lever UP to engage the

aerator.

IMPORTANT: DO NOT engage the PTO clutch

when transporting the machine.  DO NOT

engage the PTO clutch with the PTO shaft

disconnected (the aerator removed from the

tractor).

Normal Operation

IMPORTANT:  The aerator has a natural driving mo-

tion when engaged, so the speed of the tractor is

critical to ensure proper aeration and longevity of

aerator components.

1.

Adjust ground speed to properly position tines

as shown.

IMPORTANT: If ground speed is too fast, the re-

tractor plates will swing away from the front, causing

a shallow plugged hole.

IMPORTANT: If ground speed is too slow, the re-

tractor plates will swing forward and make constant

contact with the front frame, resulting in excessive

wear of tines and retractor plates.

2.

If an obstacle is encountered during operation

(sprinkler head, sidewalk, etc.), the PTO can

be disengaged and reengaged after passing

obstacle.

IMPORTANT: Minimum turning radius is 10 feet

(3.05 m).  Turning too tight can result in damage to

the turf and the aerator.

RECOMMENDATIONS FOR AERATING

For best results the ground must have a sufficient

amount of moisture to allow the tines maximum pen-

etration.

IMPORTANT: Operate the engine at full speed

when operating the aerator, to allow the engine to

produce full horsepower and to increase efficiency

of the engine cooling system.

•

Do not drive the mower backwards with the

aerator in the down position--it may cause

severe turf damage.

•

Driving the tractor too slow may cause turf

damage.

CAUTION

ALWAYS disengage the PTO clutch and

put the FSC in the NEUTRAL-PARK posi-

tion before starting the engine.

CAUTION

A safety interlock switch (seat switch)

will cause the engine to stop if the PTO

clutch is engaged and the operator is not

in the seat.  The function of this switch

should be checked by the operator rais-

ing off the seat and engaging the PTO

clutch; the engine should stop.  If the

switch is not working, it should be re-

paired or replaced before operating the

aerator.  DO NOT disconnect the safety

switches; they are for the operator’s pro-

tection.
